Background: Kawasaki disease (KD) is an acute febrile illness that largely affects young children before 5 years of age. Younger children with KD are reported to have a higher prevalence of coronary artery abnormalities. Little is known about infants in the first 3 months of age diagnosed with KD. Methods: A retrospective study was conducted at the National Institute of Pediatrics in Mexico City from 1995 to 2019. Clinical features, laboratory results and cardiac outcomes were recorded. Infants in the first 3 months of age were compared with older patients. Wilcoxon-Mann-Whitney analysis was performed for continuous variables and Fisher's exact test for categorical variables. Results: Six hundred and eighty-eight cases of KD were included in this study. Fourteen cases were diagnosed in the first three months of age. Heart failure and KD shock-syndrome was found in five cases (35.7%). Giant coronary artery aneurysms were found in six cases in the younger group (42.9%). Conclusions: Diagnosis of KD in children younger than 3 months of age is rare. In most cases, an incomplete presentation contributed to a delay diagnosis, treatment, and complications. Younger patients with KD have an increased risk of presenting cardiac complications, including giant coronary artery aneurysms, shock, and death.

A new coronavirus infection (COVID-19), which has spread widely in the human population in the past few years, is often complicated by a damage to the cardiovascular system, central nervous system, gastrointestinal tract, and respiratory system organs. The review describes the features of the clinical course and treatment of SARS-CoV-2 infection, which can lead to the development of cardiac complications both in the early and long-term periods. It is assumed that there are three main causes for the development of such complications (the affinity of the virus to endothelial proteins, the damage to blood vessels and the heart as a result of the immune response of the body and the toxic effects of drugs used to treat infection). Among the pathogenic mechanisms of the course of a new coronavirus infection that can lead to the development of cardiovascular complications, the following can be distinguished: manifestations of systemic vasculitis, coagulopathy, thrombosis, the phenomenon of “cytokine storm”, the direct cytotoxic damage to the myocardium, metabolic disorders, imbalance of the ionic composition of the blood, hypoxia and its consequences. The most common complications include myocarditis with arrhythmia (sinus tachycardia, bradycardia, atrial fibrillation and flutter, QTc prolongation, sudden cardiac death), cardiomyopathy (biventricular, isolated dysfunction of the right or left ventricle), cardiogenic shock, coagulopathy, thromboembolism (including strokes), vasculitis. Following recovery from COVID-19, many patients retain (or develop) the symptoms caused by the heart damage: a pain in the region of the heart, palpitations, appearance or aggravation of chronic heart failure, decompensation of hypertension, acute coronary syndrome. The main proposed directions for minimizing the risk of developing cardiac complications in COVID-19 patients include ECG monitoring (assessment of the QT interval, rhythm, conduction and repolarization), echocardiography in patients at risk, 24-hour ECG recording in patients who report palpitations. In addition, it is recommended to adjust the dosages of cardiotoxic drugs and to be cautious when prescribing anticoagulant therapy.

Aims Trastuzumab, the first humanized monoclonal antibody that targets human epidermal growth factor receptor 2 (ERBB2/HER2), is currently used as a first-line treatment for HER2 (+) tumours. However, trastuzumab increases the risk of cardiac complications without affecting myocardial structure, suggesting a distinct mechanism of cardiotoxicity. Methods and results We used medium from trastuzumab-treated human umbilical vein endothelial cells (HUVECs) to treat CCC-HEH-2 cells, the human embryonic cardiac tissue-derived cell lines, and human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) to assess the crosstalk between vascular endothelial cells (VECs) and cardiomyocytes. Protein mass spectrometry analysis was used to identify the key factors from VECs that regulate the function of cardiomyocytes. We applied RNA-sequencing to clarify the mechanism, by which PTX3 causes cardiac dysfunction. We used an anti-human/rat HER2 (neu) monoclonal antibody to generate a rat model that was used to evaluate the effects of trastuzumab on cardiac structure and function and the rescue effects of lapatinib on trastuzumab-induced cardiac side effects. Medium from trastuzumab-treated HUVECs apparently impaired the contractility of CCC-HEH-2 cells and iPSC-CMs. PTX3 from VECs caused defective cardiomyocyte contractility and cardiac dysfunction in mice, phenocopying trastuzumab treatment. PTX3 affected calcium homoeostasis in cardiomyocytes, which led to defective contractile properties. EGFR/STAT3 signalling in VECs contributed to the increased expression and release of PTX3. Notably, lapatinib, a dual inhibitor of EGFR/HER2, could rescue the cardiac complications caused by trastuzumab by blocking the release of PTX3. Conclusion We identified a distinct mode of cardiotoxicity, wherein the activation of EGFR/STAT3 signalling by trastuzumab in VECs promotes PTX3 excretion, which contributes to the impaired contractility of cardiomyocytes by inhibiting cellular calcium signalling. We confirmed that lapatinib could be a feasible preventive agent against trastuzumab-induced cardiac complications and provided the rationale for the combined application of lapatinib and trastuzumab in cancer therapy.

Background and Aim: Notwithstanding the improvement in therapies, patients affected by thalassemia major (TM) and intermedia (TI) are still at high risk of cardiac complications. This study aimed at evaluating the incidence and predictive factors for developing cardiac events in adult β‐TM and TI patients. Population and Methods: Data on diagnosis and clinical history were collected retrospectively; prospective data on new‐onset cardiac failure and arrhythmias, echocardiographic parameters, biochemical variables including non‐transferrin‐bound iron (NTBI) and labile plasma iron (LPI), magnetic resonance imaging (MRI) T2* measurement of hepatic and cardiac iron deposits, and iron chelation therapy were recorded during a 6‐year follow‐up. Results: Thirty‐seven patients, 29 TM and 8 TI, were included. At baseline, 8 TM patients and 1 TI patient had previously experienced a cardiac event (mainly heart failure). All patients were on chelation therapy and only 3 TM patients had mild‐to‐severe cardiac siderosis. During follow‐up, 11 patients (29.7%) experienced a new cardiac event. The occurrence of cardiac events was correlated to high LPI levels (OR 12.0, 95% CI 1.56–92.3, p.017), low mean pre‐transfusion haemoglobin (OR 0.21, 95% C.I. 0.051–0.761, p.21) and echocardiographic parameters suggestive of myocardial hypertrophy. Multivariate analysis disclosed high LPI and left ventricle mass index (LVMI) as independent variables significantly associated with cardiac events. Cardiac iron deposits measured by MRI T2* failed to predict cardiac events. Conclusion: LPI, Hb levels and echocardiographic parameters assessing cardiac remodelling are associated with cardiac events in adult TM and TI patients. LPI might represent both a prognostic marker and a potential target for novel treatment strategies. Further studies are warranted to confirm our findings on larger populations.

According to the World Health Organisation, as of October 2022, there have been 55,560,329 reported cases of SARS‐COV‐2 in patients under 19 years old. It is estimated that about 0.06% of these patients may develop MIS‐C, representing more than 2 million children worldwide. This systematic review and meta‐analysis examined the pooled prevalence of cardiovascular manifestation and cardiac complications in children hospitalised with MIS‐C. The PROSPERO register number is CRD42022327212. We included case‐report studies, case‐control studies, cohort studies, and cross‐sectional studies, as well as clinical trials or studies describing cardiac manifestations of MIS‐C and its sequelae in a paediatric population. Initially, 285 studies were selected, but there were 154 duplicates, and 81 were excluded because they did not fit the eligibility criteria. Thus, 50 studies were selected for review, and 30 were included in the meta‐analysis. A total sample size of 1445 children was included. The combined prevalence of myocarditis or pericarditis was 34.3% (95% CI: 25.0%–44.2%). The combined prevalence for echocardiogram anomalies was 40.8% (95% CI: 30.5%–51.5%), that of Kawasaki disease presentation was 14.8% (95% CI: 7.5%–23.7%), and that of coronary dilation was 15.2% (95% CI: 11.0%–19.8%). The rate of electrocardiogram anomalies was 5.3% (95% CI: 0.8%–12.3%), and the mortality rate was 0.5% (CI 95%: 0%–1.2%). Furthermore, 186 children still had complications at discharge, with a combined prevalence of such long‐lasting manifestations of 9.3% (95% CI: 5.6%–13.7%). Studies that assess whether these children will have an increased cardiovascular risk with a greater chance of acute myocardial infarction, arrhythmias, or thrombosis will be essential for healthcare planning.

Introduction:Growth differentiation factor-15 (GDF-15) is a cytokine that is associated with various metabolic and cardiac changes. Acromegaly is a chronic multisystemic disease that causes cardiac dysfunction due to an increased levels of growth hormone. We evaluated the association of GDF-15 with diastolic dysfunction in acromegaly.Methods:Fifty-four patients with acromegaly [active (n=24), inactive (n=30)] and 34 healthy controls were included in the study. The acromegaly group (AG) and control group (CG) were compared for their blood pressures, metabolic parameters, GDF-15 levels, and echocardiographic findings. The correlation analysis was performed between the GDF-15 and the parameters that may be associated with it in the AG.Results:GDF-15 was significantly higher in AG than in the CG (p

Background: Coronavirus disease-2019 (COVID-19) has been associated with pre-existing cardiac conditions as well as cardiovascular complications. The incidence rates of cardiac complications, age, and gender differences in this population are unknown. Objectives: We wanted to study the incidence of cardiac complications and mortality in patients with COVID-19. Methods: Data from the TriNetX COVID-19 global research network platform was used to identify COVID-19 patients. We compared patients with and without cardiac complications in patients with COVID-19 and obtained survival data. Results: The final cohort was composed of 81,844 patients with COVID-19. Cardiac complications occurred in 9.3% of patients as follows: acute coronary syndromes in 1.3%, heart failure in 4.4%, atrial fibrillation in 4.5%, sinus bradycardia 1.9%, ventricular tachycardia in 0.5% and complete heart block in 0.01%. Mortality was significantly higher in patients with the cardiac complications mentioned (20%) than in those without them (2.9%) (odds ratio 7.2, 95% CI, 6.7–7.7; p

Abstract Cardiac complications in patients with COVID-19 have been described in the literature with an important impact on outcome. The primary objective of our systematic review was to describe the kind of cardiac complications observed in COVID-19 patients and to identify potential predictors of cardiovascular events. The secondary aim was to analyze the effect of cardiac complications on outcome. We performed this systematic review according to PRISMA guidelines using several databases for studies evaluating the type of cardiac complications and risk factors in COVID-19 patients. We also calculated the risk ratio (RR) and 95% CI. A random-effects model was applied to analyze the data. The heterogeneity of the retrieved trials was evaluated through the I 2 statistic. Our systematic review included 49 studies. Acute cardiac injury was evaluated in 20 articles. Heart failure and cardiogenic shock were reported in 10 articles. Myocardial infarction was evaluated in seven of the papers retrieved. Takotsubo, myocarditis, and pericardial effusion were reported in six, twelve, and five articles, respectively. Arrhythmic complications were evaluated in thirteen studies. Right ventricular dysfunction was evaluated in six articles. We included 7 studies investigating 2115 patients in the meta-analysis. The RR was 0.20 (95% CI: 0.17 to 0.24; P < 0.00001, I 2 = 0.75). Acute cardiac injury represented the prevalent cardiac complications observed in COVID-19 patients (from 20 to 45% of the patients). Patients with acute cardiac injury seemed to be significantly older, with comorbidities, more likely to develop complications, and with higher mortality rates. Acute cardiac injury was found to be an independent risk factor for severe forms of SARS-CoV-2 infection and an independent predictor of mortality. Due to the scarce evidence, it was not possible to draw any conclusion regarding Takotsubo, myocarditis, pleural effusion, and right ventricular dysfunction in COVID-19 patients. Noteworthy, possible arrhythmic alterations (incidence rate of arrhythmia from 3 to 60%) in COVID-19 patients have to be taken into account for the possible complications and the consequent hemodynamic instabilities. Hypertension seemed to represent the most common comorbidities in COVID-19 patients (from 30 to 59.8%). The prevalence of cardiovascular disease (CVD) was high in this group of patients (up to 57%), with coronary artery disease in around 10% of the cases. In the majority of the studies retrieved, patients with CVD had a higher prevalence of severe form, ICU admission, and higher mortality rates.

Anorexia nervosa is an eating disorder with a multisystemic nature, affecting female adolescents predominantly. The disease is potentially fatal with cardiac complications being the leading cause. We present a clinical case of a 16-year-old girl with anorexia nervosa after a mental trauma, hospitalized in our Clinic in an extremely severe, pre comatose state with weight 26 kg, BSA – 1.12 m2 and BMI – 10.4. On the background of severe abnormalities in homeostasis, bradycardia with left ventricular extrasystoles in bigeminy and episodes of tachycardia with a frequency of 238/min. Echocardiography revealed reduce in the heart size and the left ventricular muscle mass, MI – I + degree and a small, apical pericardial effusion. During the echocardiographic follow-up, there was signifi cant hypertrophy of the left ventricle with obstruction in the outfl ow tract, with a reduction in ventricular size, without signifi cant change in left ventricular muscle mass. As a result of long-term, comprehensive treatment, with the participation of a team of specialists, the patient achieved true behavioural criticality, improved food tolerance, weight gain up to 46 kg with BMI - 18.4 and normalization of cardiac anatomy. Cardiac complications of anorexia nervosa are common, varied, and potentially lethal and require targeted cardiac monitoring and treatment. Left ventricular hypertrophy with obstruction in the ventricular outfl ow tract, fi rst described in 2006, is a rare but potentially fatal cardiac complication in patients with the disease.

Background: Despite a large amount of evidence evaluating elevated troponin I levels and adverse clinical outcomes, little is known about the role of a normal (negative) troponin I during the first 24 h of admission for risk stratification in patients with Coronavirus Disease 2019 (COVID-19). This study aims to evaluate the utility and negative predictive value of a serum troponin I level to predict in-hospital mortality. Methods: We retrospectively analyzed all adult patients (>18 years of age) with COVID-19 admitted to an HCA Healthcare facility between March 2020 and March 2021 who had a troponin I level drawn at admission. Patients were initially stratified into two groups based on their cardiac troponin I value in the first 24 h of admission (elevated vs negative). Results: A total of 65,580 patients were included in the final analysis. A negative troponin I value was associated with lesser odds of death during admission (OR = 0.32, 95 % CI 0.31–0.34, p

Coronavirus disease 2019 (COVID-19) is an ongoing global pandemic that has affected nearly 600 million people to date across the world. While COVID-19 is primarily a respiratory illness, cardiac injury is also known to occur. Cardiovascular magnetic resonance (CMR) imaging is uniquely capable of characterizing myocardial tissue properties in-vivo, enabling insights into the pattern and degree of cardiac injury. The reported prevalence of myocardial involvement identified by CMR in the context of COVID-19 infection among previously hospitalized patients ranges from 26 to 60%. Variations in the reported prevalence of myocardial involvement may result from differing patient populations (e.g. differences in severity of illness) and the varying intervals between acute infection and CMR evaluation. Standardized methodologies in image acquisition, analysis, interpretation, and reporting of CMR abnormalities across would likely improve concordance between studies. This consensus document by the Society for Cardiovascular Magnetic Resonance (SCMR) provides recommendations on CMR imaging and reporting metrics towards the goal of improved standardization and uniform data acquisition and analytic approaches when performing CMR in patients with COVID-19 infection.

Zika Virus (ZIKV) infection is a global threat. Other than the congenital neurological disorders it causes, ZIKV infection has been reported to induce cardiac complications. However, the precise treatment plans are unclear. Thus, illustrating the pathogenic mechanism of ZIKV in the heart is critical to providing effective prevention and treatment of ZIKV infection. The mechanism of autophagy has been reported recently in Dengue virus infection. Whether or not autophagy participates in ZIKV infection and its role remains unrevealed. This study successfully established the in vitro cardiomyocytes and in vivo mouse models of ZIKV infection to investigate the involvement of autophagy in ZIKV infection. The results showed that ZIKV infection is both time and gradient‐dependent. The key autophagy protein, LC3B, increased remarkably after ZIKV infection. Meanwhile, autophagic flux was detected by immunofluorescence. Applying autophagy inhibitors decreased the LC3B levels. Furthermore, the number of viral copies was quantified to evaluate the influence of autophagy during infection. We found that autophagy was actively involved in the ZIKV infection and the inhibition of autophagy could effectively reduce the viral copies, suggesting a potential intervention strategy for reducing ZIKV infection and the undesired complications caused by ZIKV.

Background: Methadone is one of the most useful opioids that can be used to achieve many therapeutic goals, and also it may be abused as an illicit drug. Methadone can cause different gastrointestinal, neurological, and cardiac complications. This study was performed to obtain a better understanding of the cardiac side effects of methadone in patients with methadone poisoning. Methods: This cross-sectional study was performed on 210 samples in Sina Hospital of Hamadan in a one-year period from March 2019 to March 2020. After assessing patients who had methadone poisoning and completing their demographic information and evaluation of changes in patients' EKGs, the data was collected and analyzed by SPSS 16 software. Results: Out of 210 participants, 178 (84.8%) were males and the rest were females. The average age of the studied patients was 39.56 years old. The study found that 6.1% of methadone-poisoned patients were illiterate. It was found in this study that the most common cardiac complications of methadone intoxication were sinus tachycardia (20%), QT interval prolongation (6.64%), and sinus bradycardia (4.3%), respectively; nevertheless, 66.2% of patients did not have any EKG abnormalities. Conclusion: According to the findings, it is necessary to have continuous cardiac monitoring for patients with methadone intoxication and by transferring such findings to medical centers, steps can be taken to use methadone more intelligently.

Feeding and Eating Disorders (FEDs) constitute a complex spectrum of psychiatric conditions, impacting physical and psychosocial well-being. This retrospective observational study aimed to dissect the electrocardiographic (ECG) alterations in pediatric patients with FEDs, correlating them with clinical factors, treatment modalities, Refeeding Syndrome (RS) and the reversibility of ECG abnormalities post-treatment. Analyzing records from a third level Italian Regional Center for FEDs in children and adolescents, the study encompassed 150 patients meeting the inclusion criteria. Sinus bradycardia was the prevalent ECG alteration, notably in Anorexia Nervosa (AN) restrictive type. Association analyses revealed links between the severity of AN, hormonal imbalances, and amenorrhea and ECG abnormalities. Pharmacological interventions, particularly antipsychotics, exhibited associations with a QT interval prolongation. RS demonstrated significant correlations with potassium and magnesium imbalances, which were linked to specific ECG changes. This study highlighted the reversibility of ECG abnormalities, concomitant with Body Mass Index improvement. This analysis underscores the critical cardiac implications of FEDs, advocating for multidisciplinary interventions and close cardiac monitoring. Early detection and holistic care are imperative in managing patients with FEDs in the developmental age, offering potential reversibility of cardiac alterations post-treatment. These findings underscore the need for prospective studies to validate these observations and delve deeper into cardiac involvement in FEDs., Competing Interests: The authors declare no conflicts of interest.

Objective: The objective of this study is to assess baseline plasma C-reactive protein (CRP) levels in patients with acute coronary syndromes and their significance in prognosis. Materials and Methods: The study was carried out at the department of internal medicine in a tertiary health care center. Fifty patients diagnosed with acute coronary syndromes (ACSs) (ST-elevation acute myocardial infarction (STEMI) or unstable angina (UA)/non-STEMI) were admitted and detailed history, clinical examination, and laboratory tests were done on each patient. All routine blood investigations were carried out along with electrocardiography and echocardiography in all patients. Plasma concentrations of CRP were measured with an ultra-sensitive latex immunoassay before reperfusion, 24 h after admission, and at discharge. Results: A total of 50 patients were taken. Thirty-eight cases were found to be male and the remaining 12 were female, of which 35 were STEMI and 15 were UA/NSTEMI. The maximum prevalence of ACS was observed in the age group of 41–50 years. Among all five presenting symptoms, chest pain was the most prevalent, followed by sweating, breathlessness, vomiting, and giddiness. The major risk factors in ACS include smoking being the most common followed by diabetes and dyslipidemia. In 16 patients, left ventricular failure was recorded, which was the most common complication followed by cardiogenic shock and atrioventricular block. ventricular tachycardia/ventricular fibrillation is recorded in five patients who died, 36 patients with complications, and three patients among 40 patients without complications where CRP levels are ≥0.6 mg/dl. Four patients out of 10 patients who showed CRP levels

Brucellosis is a zoonotic disease that remains an important public health problem in developing countries. It can affect almost all organs, including the heart. While cardiac complications of brucellosis are not common, they usually manifest as endocarditis. Brucella myocarditis, on the other hand, is a highly rare complication of brucellosis. In this case report, we present the case of a 35-year-old woman who was admitted to the hospital with severe palpitations, fever, and fatigue. Due to the patient's long history of brucellosis and clinical symptoms, she underwent cardiac evaluation, including cardiac magnetic resonance imaging, which was a promising method to diagnose Brucella myocarditis. Hopefully our patient responded well to Rifampin and Doxycycline with gentamicin. It is important to raise awareness of this rare but potentially serious complication of brucellosis and to emphasize the value of early diagnosis and treatment.

The pathophysiological mechanisms underlying severe cardiac dysfunction after aneurysmal subarachnoid haemorrhage (aSAH) remain poorly understood. In the present study, we focused on two categories of contributing factors describing the brain–heart relationship. The first group includes brain-specific cerebrospinal fluid (CSF) and serum biomarkers, as well as cardiac-specific biomarkers. The secondary category encompasses parameters associated with cerebral autoregulation and the autonomic nervous system. A group of 15 aSAH patients were included in the analysis. Severe cardiac complications were diagnosed in seven (47%) of patients. In the whole population, a significant correlation was observed between CSF S100 calcium-binding protein B (S100B) and brain natriuretic peptide (BNP) (rS = 0.62; p = 0.040). Additionally, we identified a significant correlation between CSF neuron-specific enolase (NSE) with cardiac troponin I (rS = 0.57; p = 0.025) and BNP (rS = 0.66; p = 0.029), as well as between CSF tau protein and BNP (rS = 0.78; p = 0.039). Patients experiencing severe cardiac complications exhibited notably higher levels of serum tau protein at day 1 (0.21 ± 0.23 [ng/mL]) compared to those without severe cardiac complications (0.03 ± 0.04 [ng/mL]); p = 0.009. Impaired cerebral autoregulation was noted in patients both with and without severe cardiac complications. Elevated serum NSE at day 1 was related to impaired cerebral autoregulation (rS = 0.90; p = 0.037). On the first day, a substantial, reciprocal correlation between heart rate variability low-to-high frequency ratio (HRV LF/HF) and both GFAP (rS = −0.83; p = 0.004) and S100B (rS = −0.83; p = 0.004) was observed. Cardiac and brain-specific biomarkers hold the potential to assist clinicians in providing timely insights into cardiac complications, and therefore they contribute to the prognosis of outcomes.

The relationship between the incidence of cardiovascular abnormalities and non‐alcoholic fatty liver disease (NAFLD) has long been postulated. Curcumin (CUR) is a potential anti‐atherosclerotic agent but its poor water solubility hinders its pharmacological use. Therefore, the present study aimed to investigate the effect of formulation of CUR nanoemulsion prepared using the spontaneous emulsification technique on high fat high fructose (HFHF)‐induced hepatic and cardiac complications. Fifty Wistar rats were divided into five groups. CUR nanoemulsion at doses of 5 and 10 mg/kg and conventional powdered CUR at a dose of 50 mg/kg were orally administered daily to rats for two weeks, and compared with normal control and HFHF control. Results revealed that the high dose level of CUR nanoemulsion was superior to conventional CUR in ameliorating the HFHF‐induced insulin resistance status and hyperlipidemia, with beneficial impact on rats' recorded electrocardiogram (ECG), serum aspartate aminotransferase (ALT) and alanine aminotransferase (AST) levels, leptin, adiponectin, creatine phosphokinase, lactate dehydrogenase and cardiac troponin‐I. In addition, hepatic and cardiac oxidative and nitrosative stresses, oxidative DNA damage and disrupted cellular energy statuses were counteracted. Results were also confirmed by histopathological examination. Practical applications: The use of curcumin nanoemulsion could be beneficial in combating hepatic and cardiac complications resulting from HFHF diets. [ABSTRACT FROM AUTHOR]

Emetine is one of the most highly potent anti-SARS-CoV-2 agents ever identified. In addition to having strong anti-SARS-CoV-2 activities, emetine has other valuable therapeutic effects such as strong anti-inflammatory and anti-arterial pulmonary hypertension (APH) properties, which are suitable for the treatment of COVID-19. Its proper concomitant therapeutic effect has led researchers to test this compound in clinical trials to combat COVID-19. However, due to the risks of cardiac complications, very low doses of emetine have been used in different studies, which may not have significant therapeutic effects. The p38 MAPK signaling pathway is strongly highlighted as an important operator in cardiac cellular damages such as disruption of cardiac fibroblast function and myopathy/cardiomyopathy. Inhibition of this pathway by appropriate inhibitors has also been considered by scientists as a promising strategy for the treatment of fatal host-related hyper-inflammatory immune responses following SARS-CoV-2 infection. Although remarkable stimulatory effects of emetine on activation of the p38 MAPK pathway have been reported in recent studies and strong evidence suggests that this pathway plays an effective role in the emetine's toxicities, it has not been discussed yet that emetine induced cellular cardiac complications may be due to the activation of this critical pathway. Considering these points could lead to the finding of strategies for applying the valuable potential of emetine in the treatment of COVID-19 at low risks. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to systematically assess the impact of cardiomyopathy on maternal pregnancy outcomes.Data Sources: PubMed, Ovid Embase, Ovid MEDLINE, Cochrane Library, and ClinicalTrials.gov were systematically searched from inception to April 24, 2022.Study Eligibility Criteria: Observational cohort, case-control, and case-cohort studies in human populations were included if they reported predefined maternal outcomes for pregnant women with cardiomyopathy (any subtype) and for an appropriate control population (pregnant women with no known heart disease or pregnant women with noncardiomyopathy heart disease).Methods: Two reviewers independently assessed the articles for eligibility and risk of bias, and conflicts were resolved by a third reviewer. Data were extracted and synthesized according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-Analyses of Observational Studies in Epidemiology guidelines.Results: A total of 14 studies (n=57,539,306 pregnancies) were eligible for inclusion. Women with cardiomyopathy were more likely to deliver by cesarean delivery than women with no heart disease (odds ratio, 2.96; 95% confidence interval, 2.47-3.55; I2=95%; P≤.00001) or women with noncardiomyopathy heart disease (odds ratio, 1.90; 95% confidence interval, 1.62-2.22; I2=91%; P<.00001). Having cardiomyopathy conferred a greater risk for experiencing severe maternal adverse cardiovascular events during pregnancy when compared with not having any heart disease (odds ratio, 206.64; 95% confidence interval, 192.09-222.28; I2=73%; P<.0001) or having noncardiomyopathy heart disease (odds ratio, 7.09; 95% confidence interval; 6.08-8.27; I2=88%; P<.00001). In-hospital mortality was significantly higher among women with cardiomyopathy than among women with no heart disease (odds ratio, 126.67; 95% confidence interval, 43.01-373.07; I2=87%; P<.00001) or among women with noncardiomyopathy heart disease (odds ratio, 4.30; 95% confidence interval, 3.42-5.40; I2=0%; P<.00001).Conclusion: Pregnant women with cardiomyopathy have increased risks for adverse maternal outcomes, including maternal death, when compared with both women with no heart disease and women with noncardiomyopathy heart disease. Our results highlight the importance of preconception risk assessments to allow for informed decision-making before pregnancy. Pregnancies affected by cardiomyopathy are high risk and should be managed by expert, multidisciplinary obstetrical and cardiology teams. [ABSTRACT FROM AUTHOR]

Anti-mitochondrial antibody (AMA)-positive myositis is a chronic disease characterized by skeletal muscle atrophy and is associated with cardiac complications and restrictive ventilatory impairment. This study aimed to determine the prevalence, rate of organ complications, and prognostic risk factors of AMA-positive myositis. We conducted a cross-sectional study using a nationwide questionnaire from 2011 to 2021, enrolling participants from neurology departments at 811 facilities certified by the Japanese Society of Neurology. A total of 380 patients were identified, with a prevalence rate of 0.3 per 100,000 persons. The frequencies of cardiac complications and restrictive ventilatory impairment were 53 and 33 %, respectively; whereas, those of cardiac device and respirator introduction were 32 and 22 %, respectively. The frequencies of recurrence, subacute exacerbation, no muscle strength improvement, cardiac device introduction, respirator introduction, and death were 29, 25, 54, 32, 22, and 12 %, respectively. According to univariate analysis, abnormal echocardiograms (odds ratio [OR], 5.43), restrictive ventilatory impairment (OR, 3.70), and inflammatory changes revealed by muscle biopsy (OR, 0.34) were associated with subacute exacerbations, whereas abnormal echocardiograms (OR, 8.00) and durations from onset to admission and diagnosis (OR, 2.99) were associated with cardiac device introduction. Multivariable analysis showed that restrictive ventilatory impairment was associated with recurrence (adjusted OR, 3.01), adjusted for the duration from onset to admission and diagnosis, and with subacute exacerbations (adjusted OR, 3.86), adjusted for abnormal echocardiograms and inflammatory changes. AMA-positive myositis is characterized by severe and urgent organ complications, and anticipatory management is critical for management of this disease. • The prevalence of anti-mitochondrial antibody-positive myositis is 0.3 per 100,000. • This disease is frequently accompanied by severe restrictive ventilatory impairment. • Ventilatory impairment was associated with recurrence and subacute exacerbations. • This disease is also frequently associated with severe cardiac sequalae.

Studies on Kawasaki disease (KD) in Arab countries are scarce, often providing incomplete data. This along with the benefits of multicenter research collaboratives led to the creation of the KD Arab Initiative [Kawarabi] consortium. An anonymous survey was completed among potential collaborative Arab medical institutions to assess burden of KD in those countries and resources available to physicians. An online 32-item survey was distributed to participating institutions after conducting face validity. One survey per institution was collected. Nineteen physicians from 12 countries completed the survey representing 19 out of 20 institutions (response rate of 95%). Fifteen (79%) institutions referred to the 2017 American Heart Association guidelines when managing a patient with KD. Intravenous immunoglobulin (IVIG) is not readily available at 2 institutions (11%) yet available in the country. In one center (5%), IVIG is imported on-demand. The knowledge and awareness among countries' general population was graded (0 to 10) at median/interquartiles (IQR) 3 (2–5) and at median/IQR 7 (6–8) in the medical community outside their institution. Practice variations in KD management and treatment across Arab countries require solid proactive collaboration. The low awareness and knowledge estimates about KD among the general population contrasted with a high level among the medical community. The Kawarabi collaborative will offer a platform to assess disease burden of KD, among Arab population, decrease practice variation and foster population-based knowledge. [ABSTRACT FROM AUTHOR]

Data on feasibility, management, and outcomes of liver transplantation (LT) in patients with pre-existing left ventricular systolic dysfunction (LVSD), severe coronary artery disease (CAD) or cirrhotic cardiomyopathy (CCM) is scarce. We reviewed outcomes of living donor liver transplantation (LDLT) in recipients with LVSD (ejection fraction [EF] < 50%) from our series of 1946 LDLT's performed between July 2010 and July 2018. LVSD was detected in 12 male patients with a mean age, BMI and MELD of 52 ± 9 years, 25 ± 5 kg/m2, and 19 ± 4 respectively. Out of these, 6 patients had CAD (2 with previous coronary artery bypass graft, 1 following recent percutaneous transluminal coronary angioplasty, 2 post myocardial infarction, 1 noncritical CAD), and 6 had CCM. The EF ranged from 25% to 45%. Ethanol was the predominant underlying etiology for cirrhosis (50%). During LDLT, 2 patients developed ventricular ectopic rhythm and were managed successfully with intravenous lidocaine. Stress cardiomyopathy manifested in 3 patients post operatively with decreased EF, of which 2 improved, while 1 needed IABP support and succumbed to multiorgan failure on 8th postoperative day (POD). Another patient died on POD30 due to septic shock. Both these patients had higher MELD scores (actual MELD), extremes of BMI (17.3and 35.8 kg/m2) and were diabetic. There were no long-term cardiac deaths. The 1-year, and 5-year survival were 75%, and 66%, respectively. Among potential LT recipients with LVSD, those with stable CAD and good performance status, and well optimized CCM patients may be considered for LDLT after careful risk stratification in experienced centers.

There have been several local and systemic adverse events associated with mRNA COVID‐19 vaccines. Pericarditis, myocarditis and myocardial infarction are examples of cardiac complications related to these vaccines. In this article, we conducted a systematic review of case reports and case series to identify the clinical profile, investigations, and management of reported cardiac complications post‐mRNA COVID‐19 vaccines. We systematically searched PubMed, Scopus, Web of Science, and Google Scholar, as well as the medRxiv preprint server, with terms including: 'SARS‐CoV‐2', 'COVID‐19', 'messenger RNA vaccine*', 'mRNA‐1273 vaccine', 'BNT162 vaccine', 'myocarditis', 'pericarditis', 'stroke' and 'Myocardial Ischemia' up to 25 September 2021. Studies were excluded if they were not case reports or case series, or reported cases from non‐mRNA vaccines. Case reports and case series were included that investigated the potential cardiac complications associated with mRNA COVID‐19 vaccines. The JBI checklist was used to assess quality and data synthesis was conducted using a qualitative methodology called narrative synthesis. Sixty‐nine studies, including 43 case reports and 26 case series, were included. Myocarditis/myopericarditis and pericarditis were the most common adverse events among the 243 reported cardiac complications, post mRNA COVID‐19 vaccination. Males with a median age of 21 years had the highest frequency of myocarditis. Almost three quarters (74.4%) of cases with myocarditis had received the BNT162b2 vaccine and 87.7% had received the second dose of the vaccine. Chest pain (96.1%) and fever (38.2%) were the most common presentations. CK‐MB, troponin, and NT‐proBNP were elevated in 100%, 99.5% and 78.3% of subjects, respectively. ST‐segment abnormality was the most common electrocardiogram feature. Cardiac magnetic resonance imaging, which is the gold‐standard approach for diagnosing myocarditis, was abnormal in all patients diagnosed with myocarditis. Non‐steroidal anti‐inflammatory drugs were the most prescribed medication for the management of myocarditis. Apart from inflammatory conditions, some rare cases of Takotsubo cardiomyopathy, myocardial infarction, myocardial infarction with non‐obstructive coronary arteries, and isolated tachycardia were also reported following immunisation with mRNA COVID‐19 vaccines. We acknowledge that only reviewing case reports and case series studies is one potential limitation of our study. We found that myocarditis was the most commonly reported adverse cardiac event associated with mRNA COVID‐19 vaccines, which presented as chest pain with a rise in cardiac biomarkers. Further large‐scale observational studies are recommended. [ABSTRACT FROM AUTHOR]

Abstract Background Previous reports have shown various cardiac complications to be associated with COVID-19 including: myocardial infarction, microembolic complications, myocardial injury, arrythmia, heart failure, coronary vasospasm, non-ischemic cardiomyopathy, stress (Takotsubo) cardiomyopathy, pericarditis and myocarditis. These COVID-19 cardiac complications were associated with respiratory symptoms. However, our case illustrates that COVID-19 myopericarditis with cardiac tamponade can present without respiratory symptoms. Case presentation A 58-year-old Caucasian British woman was admitted with fever, diarrhoea and vomiting. She developed cardiogenic shock and Transthoracic echocardiogram (TTE) found a pericardial effusion with evidence of cardiac tamponade. A nasopharyngeal swab showed a COVID-19 positive result, despite no respiratory symptoms on presentation. A pericardial drain was inserted and vasopressor support required on intensive treatment unit (ITU). The drain was removed as she improved, an antibiotic course was given and she was discharged on day 12. Conclusions Our case demonstrates that patients without respiratory symptoms could have COVID-19 and develop cardiac complications. These findings can aid timely diagnosis of potentially life-threatening COVID-19 myopericarditis with cardiac tamponade.

Background: Accumulating evidence demonstrates that white-coat hypertension (WCH) are associated with several risks and complications. In this study, we aimed to investigate the adverse effects of WCH compared with hypertensive and normotensive patients. Methods: A retrospective cohort study was conducted over five years. Blood pressure (BP) data was collected from both clinic visits and 24-h ambulatory blood pressure monitoring (ABPM) reports. Epidemiological data and complications, cardiac and noncardiac, were also recorded. Results: In total, 286 participants who were followed up for at least three years were included. The sample was divided into 99 normotensive patients (as a control group), 94 patients with clinically diagnosed hypertension (HTN), and 93 patients with WCH. Ischemic heart disease (IHD) was the most noted complication in the WCH group with a relative risk of 9.58 (1.23–74.16) (P = 0.008). Acute coronary syndrome (ACS) was significantly correlated with a relative risk of 2.06 (0.52–13.38). No significant correlation was noted with noncardiac complications. Both HTN and WCH groups showed a significant association with blood pressure variability (BPV). WCH was associated with an increased BPV in ambulatory daytime systolic measurements (P = 0.031) and a unique increase in diastolic measurement variability in office BP measurements (P = 0.020). Conclusion: WCH should be managed as HTN. WCH is associated with cardiac complications, particularly IHD, specifically in patients 55 years and older. WCH was significantly associated with a higher BPV in both ABPM and office-based measurements.

Background The decrease in effective blood volume after burns is closely related to abnormal heart function. Objective To investigate whether serum human epididymis protein 4 (HE4), an indicator of early renal injury, contributes to increased risk of cardiac complications in patients with burns. Methods Within 24 hours after hospital admission, clinical condition assessment and biochemical testing in patients with burns were performed. Multivariate analysis was performed by evaluating the relationship between serum HE4 levels and risk of cardiac complications (cardiac insufficiency, arrhythmia, and myocardial infarction) during hospitalization. Results The number (percentage) of cardiac complications in all included patients with burns was 80 (15.6%). The results of sensitivity analysis suggest that elevated serum HE4 levels were related to higher risk of cardiac complications in patients with sepsis (OR = 2.1; 95% CI, 1.19–3.17; P <.001) and in patients without sepsis (OR = 2.29; 95% CI, 1.33–4.71l; P =.005), respectively, after adjustments for clinical confounding factors were made. Sepsis did not have a modification effect on the association between serum and cardiac complications among these patients. Also, the results of ROC curve analysis showed that serum HE4 levels have good predictive value for predicting cardiac complications in patients with burns (AUC = 0.708; 95% CI, 0.61–0.81; P <.001). Conclusions In the current study, we identified that elevated HE4 levels contributed to increased risk of cardiac complications in the hospital in patients with burns. This novel finding suggests that burn patients with serum HE4 may provide the opportunity to predict cardiac complications before hospital admission. [ABSTRACT FROM AUTHOR]

Worldwide, more than 200 million non-cardiac surgeries are performed annually, and this number is constantly increasing; cardiac complications are the leading cause of death in such surgeries. So, in a multicenter study conducted in 27 countries, cardiovascular complications were present in 68% of cases of death in the postoperative period. Registers of recent years have shown that the number of such complications remains high, for example, with a dynamic assessment of troponins, perioperative myocardial damage was detected in 13-18% of cases. This review provides a critical analysis of the step-by-step algorithm for assessing cardiac risk of non-cardiac operations considering the emergence of new publications on this topic. The review discusses new data on risk assessment scales, functional state assessment, the use of non-invasive tests, biomarkers, the role of preventive myocardial revascularization in the preoperative period, and drug therapy. The issues of non-cardiac operations after percutaneous coronary intervention, perioperative myocardial damage are considered separately. The review emphasizes the difficulties in obtaining evidence, conducting randomized clinical trials in this section of medicine, which do not allow obtaining unambiguous conclusions in most cases and lead to inconsistencies and ambiguities in the recommendations of various expert groups. This review will help practitioners navigate this issue and help to use the optimal diagnostic and treatment strategy before performing non-cardiac surgery.

Abstract Background This study aimed to evaluate the effect of dipyridamole-thallium scanning (DTS) on the rates of 90-day cardiac complications and 1-year mortality in patients with a femoral neck fracture treated with hemiarthroplasty. Methods Between 2008 and 2015, 844 consecutive patients who underwent cemented or cementless hemiarthroplasty were identified from the database of a single level-one medical center. One-hundred and thirteen patients (13%) underwent DTS prior to surgery, and 731 patients (87%) did not. Patient characteristics, comorbidities, surgical variables, and length of the delay until surgery were recorded. A propensity score-matched cohort was utilized to reduce recruitment bias in a 1:3 ratio of DTS group to control group, and multivariate logistic regression was performed to control confounding variables. Results The incidence of 90-day cardiac complications was 19.5% in the DTS group and 15.6% in the control group (p = 0.343) among 452 patients after propensity score-matching. The 1-year mortality rate (10.6% vs 13.3%, p = 0.462) was similar in the two groups. In the propensity score-matched patients, utilization of DTS was not associated with a reduction in the rate of 90-day cardiac complications (matched cohort, adjusted odds ratio [aOR] = 1.32; 95% confidence interval [CI] 0.75–2.33, p = 0.332) or the 1-year mortality rate (aOR = 0.62; 95% CI 0.27–1.42, p = 0.259). Risk factors for cardiac complications included an American Society of Anesthesiologists grade ≥ 3 (OR 3.19, 95% CI 1.44–7.08, p = 0.004) and pre-existing cardiac comorbidities (OR 5.56, 95% CI 3.35–9.25, p < 0.001). Risk factors for 1-year mortality were a long time to surgery (aOR 1.15, 95% CI 1.06–1.25, p = 0.001), a greater age (aOR 1.05, 95% CI 1.00 to 1.10, p = 0.040), a low body mass index (BMI; aOR 0.89, 95% CI 0.81–0.98, p = 0.015), and the presence of renal disease (aOR 4.43, 95% CI 1.71–11.46, p = 0.002). Discussion Preoperative DTS was not associated with reductions in the rates of 90-day cardiac complications or 1-year mortality in patients with a femoral neck fracture undergoing hemiarthroplasty. The necessity for DTS should be re-evaluated in elderly patients with femoral neck fractures, given that this increases the length of the delay until surgery. Level of evidence Prognostic level III

The objective of the study was to explore the incidence and risk factors of perioperative cardiac complications (PCCs) for the oldest-old patients with CAD undergoing noncardiac surgery, which have not been evaluated previously.Patients and Methods: A total of 547 patients, aged over 80 years, with a history of CAD who underwent noncardiac surgery were enrolled in this retrospective study. Perioperative clinical variables were extracted from the electronic medical records database. The primary outcome was the occurrence of PCCs intraoperatively or within 30 days postoperatively, defined as any of the following complications: acute coronary syndrome, heart failure, new-onset severe arrhythmia, nonfatal cardiac arrest, and cardiac death. Multivariate logistic regression analysis and multivariate Cox regression model were both performed to estimate the risk factors of PCCs. The incidence of PCCs overtime was illustrated by the Kaplan–Meier curve with a stratified Log-rank test.Results: One hundred six (19.4%) patients developed at least one PCC, and 15 (2.7%) patients developed cardiac death. The independent risk factors contributing to PCCs were age ≧85 years; body mass index ≧30 kg/m2; the history of angina within 6 months; metabolic equivalents < 4; hypertension without regular treatment; preoperative ST-T segment abnormality; anesthesia time > 3 h and drainage ≧200 mL within 24 h postoperatively.Conclusion: The incidence of PCCs in elderly patients over 80 years with CAD who underwent noncardiac surgery was high. Comprehensive preoperative evaluation, skilled surgical technique, and regular postoperative monitoring may help to reduce the occurrence of PCCs in this high-risk population.Keywords: oldest-old, coronary artery disease, noncardiac surgery, perioperative, cardiac complications

BackgroundCardiac complications are important causes of morbidity in patients with thalassemia intermedia (TI). We aimed to assess left ventricular (LV) function, using new tissue Doppler imaging (TDI) indices, in order to diagnose early ventricular impairment in asymptomatic children and adolescence with the TI.Materials and MethodsWe investigated possible differences in echocardiographic systolic and diastolic parameters between a population of 28 asymptomatic patients (mean age, 13.6 ± 5.7 years) and 35 age-matched healthy control members. All of them underwent 2-D, pulsed Doppler, and tissue Doppler echocardiographic studies for the assessment of the LV mass, Trans-mitral velocities, mitral annular systolic and diastolic velocities, myocardial performance index (MPI), and myocardial acceleration during isovolumic contraction (IVA). The cardiac iron load was estimated by magnetic resonance imaging T2*.ResultsLeft ventricular hypertrophy (LVH) was found in 13 (46.4%) patients. We found significantly reduced TDI-derived peak systolic myocardial velocity (s′) in patients, whereas no significant difference was identified between the patients and control group members when the IVA was compared. The ratio of peak mitral inflow velocity to annular early diastolic velocity (E/e′) of the mitral valve as an index of the diastolic function was significantly higher in patients (9 ± 1 vs. 6 ± 1, p < 0.05). Choosing a TDI-derived MPI > 0.33 as a cutoff point, the global LV dysfunction was detected with a sensitivity of 78% and a specificity of 80%. The patients with LVH significantly exhibited higher values of TDI-MPI and lower values of s′ velocity and IVA when compared against the subjects with normal LV mass.ConclusionSubtle LV systolic and diastolic dysfunction develops early in young patients with the TI who have normal cardiac iron concentration. Moreover, LV remodeling as a main cardiac adaptive response plays a principal role in developing myocardial impairment.

AimsTo perform a systematic review assessing the clinical manifestations and outcomes of cardiorenal syndrome or the presence of both cardiac and renal complications in the 2019 coronavirus disease (COVID-19) patients.MethodsAll relevant studies about cardiorenal syndrome or both cardiac and renal complications in COVID-19 patients were retrieved on PUBMED, MEDLINE, and EMBASE from December 1, 2019 to February 20, 2022.ResultsOur search identified 15 studies including 637 patients with a diagnosis of cardiorenal syndrome or evidence of both cardiac and renal complications followingSARS-CoV-2 infection. They were male predominant (66.2%, 422/637), with a mean age of 58 years old. Cardiac complications included myocardial injury (13 studies), heart failure (7 studies), arrhythmias (5 studies), or myocarditis and cardiomyopathy (2 studies). Renal complications manifested as acute kidney injury with or without oliguria. Patients with cardiorenal injury were often associated with significantly elevated levels of inflammatory markers (CRP, PCT, IL-6). Patients with a diagnosis of cardiorenal syndrome or evidence of both cardiac and renal complications had more severe disease and poorer prognosis (9 studies).ConclusionThe presence of either cardiorenal syndrome or concurrent cardiac and renal complications had a significant impact on the severity of the disease and the mortality rate among patients with COVID-19 infection. Therefore, careful assessment and management of potential cardiac and renal complications in patients with COVID-19 infection are important to improve their outcomes.

Cardiac complications following non-cardiac surgeries are a significant cause of perioperative morbidity and mortality. This meta-analysis aimed to assess the incidence and predictors of cardiac complications in patients undergoing elective and urgent non-cardiac surgeries. A comprehensive literature search was conducted in PubMed, Embase, and Cochrane Library databases for studies published between 2010 and 2024. Eligible studies evaluated cardiac outcomes such as myocardial infarction, arrhythmias, congestive heart failure, and cardiac arrest, reporting odds ratios (ORs) and confidence intervals (CIs) for associated risk factors. A total of seven studies were included, encompassing data from diverse populations and surgical settings. The pooled analysis revealed an overall incidence of cardiac complications of 2.8% (95% CI = 2.1%-3.5%) in elective surgeries and 5.4% (95% CI = 4.0%-6.8%) in urgent surgeries. Urgent procedures were associated with a significantly higher risk of cardiac events compared to elective surgeries (OR = 1.42, 95% CI = 1.15-1.76). Independent predictors of cardiac complications included advanced age, preoperative comorbidities such as hypertension and diabetes, reduced left ventricular ejection fraction, and elevated preoperative cardiac biomarkers, such as troponin levels. Significant heterogeneity was observed across studies, largely attributed to variations in surgical populations and definitions of cardiac outcomes. Subgroup analyses demonstrated that age >75 years (OR = 1.50, 95% CI = 1.20-1.90) and emergency procedures in patients with pre-existing cardiovascular disease (OR = 1.75, 95% CI = 1.30-2.10) were critical determinants of adverse outcomes. Additionally, intraoperative hypotension and prolonged surgical duration were associated with increased risk. The findings underscore the need for comprehensive preoperative risk assessment and tailored perioperative management strategies to mitigate cardiac risk, particularly in high-risk patients undergoing urgent surgeries. Enhanced utilization of preoperative biomarkers and risk scoring systems, coupled with vigilant intraoperative monitoring, may help reduce the burden of cardiac complications. While improvements in perioperative care have mitigated some risks, disparities remain, especially in resource-limited settings, warranting further research., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

Infective endocarditis commonly presents with fever, malaise, fatigue, and chest pain. However, this case report details an atypical presentation of infective endocarditis when a 63-year-old male patient was referred by his general practitioner to the emergency department with shortness of breath and substantial weight loss to investigate his symptomatic anemia. His initial assessments revealed severe iron deficiency anemia without any gastrointestinal or any other source of bleeding. Further investigations demonstrated that the patient suffered from infective endocarditis caused by a rare causative organism, Streptococcus anginosus . Hence, our case report highlights the atypical presentation and the rare organism in addition to the possibility of close association between iron deficiency anemia and subacute bacterial endocarditis. The patient was managed by culture-guided intravenous antibiotics and discharged after serial negative cultures., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

Aims: We aimed to analyse serious cardiac adverse drug reactions to COVID-19 vaccines from the Europe-wide EudraVigilance database., Methods and Results: In this retrospective, cross-sectional study, the EudraVigilance database was searched to identify suspected serious cardiac post-vaccination adverse drug reactions to COVID-19 vaccines. This data was coupled with the number of total vaccine doses administered in the European Economic Area for Comirnaty (Pfizer BioNTech), Spikevax (Moderna), Vaxzevria (AstraZeneca), Jcovden (Janssen), Nuvaxovid (Novavax), products, available from the European Centre for Disease Prevention and Control 'Vaccine Tracker' database. The analysis included 772 228 309 administered doses of eligible vaccines from the 'Vaccine Tracker' database and 86 051 eligible records of cardiac adverse drug reactions from the EudraVigilance database. The frequency of most of the investigated adverse drug reactions was very rare (<1/10 000 i.e. <100/1 000 000 doses). The lowest risk of any serious cardiac adverse drug reactions was noticed for vaccination with Comirnaty (135.5 per million doses), while Spikevax, Jcovden, Vaxzevria, and Nuvaxovid were characterized by higher risk (respectively, 140.9, 194.8, 313.6, and 1065.2 per million doses). The most common complications of vaccinations included syncope, arrhythmia, tachycardia, palpitations, angina pectoris, hypertension, myocarditis, thrombosis, and pulmonary embolism., Conclusion: The risk of serious cardiac adverse drug reactions to COVID-19 vaccines is low and the benefit of active immunization against that disease seems to outweigh the potential risk of serious post-vaccination cardiac adverse drug reactions., (© The Author(s) 2024.

Rheumatic fever (RF) remains a significant global health concern, particularly in regions with limited access to health care. Despite its association with group A streptococcal infections, diagnosing RF can be challenging because of its diverse clinical presentations, including cardiac manifestations such as heart block. We present the case of a 13-year-old boy initially misdiagnosed with appendicitis whose subsequent evaluation revealed acute RF (ARF) with associated cardiac complications, including Mobitz type II heart block. Comprehensive cardiac investigations confirmed the diagnosis, highlighting the importance of considering ARF in patients presenting with cardiac abnormalities. Early recognition and management of ARF are crucial, particularly in cases involving cardiac manifestations such as heart block. Favorable outcomes were observed with appropriate medical therapy, emphasizing the effectiveness of multidisciplinary management in preventing disease progression., Competing Interests: The authors have reported that they have no relationships relevant to the contents of this article to disclose., (© 2024 The Authors.)

Background: Among cardiac complications of breast cancer radiotherapy (BC RT), there are very limited data on arrhythmia and conduction disorders, in particular severe cases requiring permanent pacemaker implantation (PPMI). Therefore, this exploratory study aimed to evaluate the risk of PPMI for BC patients treated with RT, compared with the general population and with BC patients not treated with RT. Methods: The study was performed on a 1/97 representative sample of the French health care database (EGB database). Adult women with a first BC treated with or without RT between 2008 and 2016 were included, followed until 2018, and de novo PPMI were identified. We compared the PPMI incidence in BC cohort relative to the general population with standardized incidence ratio (SIR) and evaluated the risk of PPMI in RT patients compared to patients without RT with a competing risk survival analysis. Results: A total of 3853 BCE patients were included. Among BC patients treated with RT, 28 PPMI cases were observed compared with 13 expected cases, corresponding to a SIR of 2.18 [95% CI: 1.45–3.06]. For BC patients not treated with RT, the SIR was 1.01 [95% CI: 0.40–1.90]. Patients treated with RT showed a borderline significant higher risk of PPMI compared with those not treated with RT (subdistribution Hazard Ratio = 2.08, 95% CI 0.87–4.97, p = 0.09). Conclusions: Our exploratory findings indicate that, over the last decade in France, BC patients treated with RT appeared to be at higher risk of PPMI than general population. Further studies are needed to expand on this topic.

Patients rely on healthcare providers as their most credible and frequent source of vaccine information. It is therefore crucial that healthcare providers are informed and have evidence-based, objective and clear guidance on vaccine efficacy and specific adverse events following immunisation (AEFI). Reported serious AEFIs are extremely rare for the COVID-19 vaccines. This article discusses the main AEFIs attributed to COVID-19 vaccines, including neurological complications of Guillain-Barré syndrome (GBS) and acute transverse myelitis (ATM), thrombosis; cardiac complications, including myocarditis, pericarditis and cardiomyopathy; and allergic reactions such as anaphylaxis, urticaria and skin rashes. The benefits of COVID-19 vaccination outweigh the risks; however, it is important that healthcare providers are aware of the risks and know how to recognise and manage them. [ABSTRACT FROM AUTHOR]

• Over 11 types of cardiac complications were reported in COVI-19 patients. • This is a first umbrella review study that reports the summarized data of 26 meta-analysis studies. • Our results confirmed that non-survivors of COVID-19 patients compared to severe and non-severe ones had the most incidence rate of cardiac complication. • The severe patients had a high incidence rate of cardiac complications compared with the non-severe patients. • Having cardiac complications was the main predictor of poor outcomes for COVID-19 patients. COVID-19 causes fatal cardiac damages. Despite many overwhelming meta-analysis related to cardiac complications following COVID-19 disease, no umbrella meta-analysis study has been conducted. We aimed to report the summarized pooled incidences of cardiac complications in the overall, critically ill, and deceased patients, compare the cardiac complications between the severe/non-severe or deceased/non-deceased patients, and also compare poor outcomes between patients with/without acute myocardial injury (AMI). PubMed, Scopus, web of science, Cochrane, ProQuest, Springer, Sage journals were searched before April 2021. After assessing the quality and duplicate data, data were run by the random/fixed-effect models, I2 heterogeneity index, Egger's test, and sensitivity analysis. After removing duplicate data, in the overall COVID-19 patients, the pooled incidence of AMI, heart failure, arrhythmia, cardiac arrest, and acute coronary syndrome (ACS) were 21%, 14%, 16%, 3.46%, and 1.3%, respectively. In the patients with severe disease, the pooled incidence of AMI and shock were 33 and 35%, respectively. Similarly, in the deceased COVID-19 patients, the pooled incidence rate of AMI and arrhythmia were 56% and 47.5%, respectively. The patients with severe disease were at higher risk of AMI (RR = 5.27) and shock (OR = 20.18) compared with the non-severe cases. Incidence of AMI was associated with transfer to the intensive care units (ICU) (RR = 2.92) and mortality (RR = 2.57, OR = 8.36), significantly. Cardiac complications were found to be increased alarmingly in COVID-19 patients. Baseline and during hospitalization checking with electrocardiography, echocardiography, and measuring of cardiac biomarkers should be applied. [ABSTRACT FROM AUTHOR]

Background and Objectives: We present a retrospective report on the cardio-hematological care of hematology patients at a university hospital in Poland during the COVID-19 pandemic. Materials and Methods: The number of hospitalizations at the Hematology Department and cardio-hematology consultations throughout 2019 and 2020 was analyzed. The types of cardiac procedures, risk factors, and complications were also assessed. Results: A significant reduction in the number of hospitalizations was observed in 2020 as compared to 2019. However, there were no significant differences in the incidence of hematological diseases between both of the analyzed years. In 2019, 299 cardiac consultations were performed in hematological patients, and there was a total of 352 such consultations performed in 2020 (p = 0.042). Less high-risk tests (transesophageal and stress echocardiography) were performed in 2020, in favor of the use of cardiac computed tomography in cardiac diagnostics as it was safer during the pandemic. At least one cardiovascular risk factor during cardiac consultation was noted in 42% and 48% of hematological patients in 2019 and 2020, respectively. Among 651 examined hematological patients, the most common findings were mild cardiac complications of hemato-oncological treatment, which were found in 57 patients. Conclusions: This study seems to confirm that during a pandemic there is an increased demand for well-organized cardio-hematology consultations. [ABSTRACT FROM AUTHOR]

Objective To examine the effectiveness and safety of epidural analgesia in the presurgical period in patients with hip fracture undergoing surgical repair. Design Systematic review. Methods The study protocol was registered with the PROSPERO systematic reviews registry with the (identifier CRD42019140396). Electronic databases were searched for randomized controlled trials comparing preoperative epidural analgesia with other forms of pain management in patients with a hip fracture. The primary outcomes included perioperative cardiac events and death. Pain, noncardiac complications, and adverse effects were also examined as secondary outcomes. The heterogeneity of the included studies was assessed with the I 2 statistic, and a random-effects meta-analysis was conducted once sufficient homogeneity was demonstrated. Results Four studies, which included a total of 221 patients, met the inclusion criteria. Preoperative epidural analgesia resulted in fewer cardiac events, which was a reported outcome in two included studies (relative risk 0.30; 95% confidence interval 0.14–0.63; I 2=0%). Preoperative epidural analgesia was also associated with a decreased perioperative mortality rate in a meta-analysis of two studies (relative risk 0.13; 95% confidence interval 0.02–0.98; I 2 = 0%). Pain was not pooled because of variability in assessment methods, but preoperative epidural analgesia was associated with reduced pain in all four studies. Conclusions Preoperative epidural analgesia for hip fracture may reduce perioperative cardiac events and deaths, but the number of included studies in this systematic review was low. More research should be done to determine the benefit of early epidural analgesia for patients with hip fracture. [ABSTRACT FROM AUTHOR]

Aims: Infection by SARS‐CoV‐2 may result in a systemic disease and a proportion of patients ranging 15%–44% experienced cardiac injury (CI) diagnosed by abnormal troponin levels. The aim of the present study was to analyse the clinical characteristics of a large series of hospitalized patients for COVID‐19 in order to identify predisposing and/or protective factors of CI and the outcome. Methods and results: This is an observational, retrospective study on patients hospitalized in two Italian centres (San Raffaele Hospital and Cremona Hospital) for COVID‐19 and at least one high‐sensitivity cardiac troponin (hs‐cTnt) measurement during hospitalization. CI was defined if at least one hs‐cTnt value was above the 99th percentile. The primary end‐point was the occurrence of CI during hospitalization. We included 750 patients (median age 67, IQR 56–77 years; 69% males), of whom 46.9% had history of hypertension, 14.7% of chronic coronary disease and 22.3% of chronic kidney disease (CKD). Abnormal troponin levels (median troponin 74, IQR 34–147 ng/l) were detected in 390 patients (52%) during the hospitalization. At multivariable analysis age, CKD, cancer, C‐reactive protein (CRP) levels were independently associated with CI. Independent predictors of very high troponin levels were chronic kidney disease and CRP levels. Patients with CI showed higher rate of all‐cause mortality (40.0% vs. 9.1%, p = 0.001) compared to those without CI. Conclusion: This large, multicentre Italian study confirmed the high prevalence of CI and its prognostic role in hospitalized patients with COVID‐19, highlighting the leading role of systemic inflammation for the occurrence of CI.

Aims/hypothesis: Hypoglycaemia is a common side effect of insulin and some other antihyperglycaemic agents used to treat diabetes. Severe hypoglycaemia has been associated with adverse cardiovascular events in trials of intensive glycaemic control in type 2 diabetes. The relationship between non-severe hypoglycaemic episodes (NSHEs) and severe hypoglycaemia in type 2 diabetes has been documented. However, an association between more frequent NSHEs and cardiovascular events has not been verified. This post hoc analysis of the LEADER (Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results) trial aimed to confirm whether there is an association between NSHEs and severe hypoglycaemic episodes in individuals with type 2 diabetes. In addition, the possible association between NSHEs and major adverse cardiac events (MACE), cardiovascular death and all-cause mortality was investigated. Methods: LEADER was a double-blind, multicentre, placebo-controlled trial that found that liraglutide significantly reduced the risk of MACE compared with the placebo. In this post hoc analysis, we explored, in all LEADER participants, whether the annual rate of NSHEs (defined as self-measured plasma glucose <3.1 mmol/l [56 mg/dl]) was associated with time to first severe hypoglycaemic episode (defined as an episode requiring the assistance of another person), time to first MACE, time to cardiovascular death and time to all-cause mortality. Participants with <2 NSHEs per year were used as reference for HR estimates. Cox regression with a time-varying covariate was used. Results: We demonstrate that there is an association between NSHEs (2–11 NSHEs per year and ≥12 NSHEs per year) and severe hypoglycaemic episodes (unadjusted HRs 1.98 [95% CI 1.43, 2.75] and 5.01 [95% CI 2.84, 8.84], respectively), which was consistent when baseline characteristics were accounted for. Additionally, while no association was found between participants with 2–11 NSHEs per year and adverse cardiovascular outcomes, higher rates of NSHEs (≥12 episodes per year) were associated with higher risk of MACE (HR 1.50 [95% CI 1.01, 2.23]), cardiovascular death (HR 2.08 [95% CI 1.17, 3.70]) and overall death (HR 1.80 [95% CI 1.11, 2.92]). Conclusions/interpretation: The analysis of data from the LEADER trial demonstrated that higher rates of NSHEs were associated with both a higher risk of severe hypoglycaemia and adverse cardiovascular outcomes in individuals with type 2 diabetes. Therefore, irrespective of the cause of this association, it is important that individuals with high rates of hypoglycaemia are identified so that the potentially increased risk of cardiovascular events can be managed and steps can be taken to reduce NSHEs.

Introduction: Serum brain-type natriuretic peptide (BNP) levels may be involved in detecting the breakdown of defense mechanisms in pregnant women. BNP and N-terminal pro-BNP (NT-proBNP) levels can be used in emergency settings as a biomarker to rule out or confirm cardiac complications. The present study was conducted as an attempt to evaluate the performance of BNP and NT-proBNP as diagnostic tools for cardiac complications, including heart failure and pre-eclampsia, in pregnant and recently-delivered women. Methods: This meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. To extract the data, articles meeting the inclusion criteria were directly reviewed by two of the authors. Disputes were resolved through discussion with all authors before data mining. In cases of unresolved disagreement, a third reviewer was consulted to achieve consensus. A quantitative analysis of the total bias of publications was performed using Stata software version 14.0, using funnel plots and Deek's test. Results: Overall, 13 unique studies were included in this review. The pooled sensitivity, specificity and positive and negative predictive values for diagnosing cardiac complications in pregnant women when BNP level was ≤ 100 ng/L, were determined to be 95, 62, 71 and 91%, respectively. The corresponding measures when the BNP levels were 100–500 ng/L were calculated to be 98, 92, 97 and 92%, respectively. The pooled sensitivity, specificity and positive and negative predictive values for diagnosing cardiac complications in pregnant women using NT-proBNP were 78, 74, 20.5 and 97%, respectively. Conclusion: Our results suggest that both BNP and NT-proBNP levels can be used as diagnostic tools among pregnant and newly-delivered women to diagnose cardiac complications, including heart failure and pre-eclampsia. While BNP showed a relatively better diagnostic accuracy compared to NT-proBNP, it must be noted that the number of studies evaluating NT-proBNP included in this meta-analysis was low and the studies were inconsistent in terms of cutoff value. Further studies are required to confirm the prospective use of BNP and NT-pro BNP in assessing common symptoms that indicate cardiac complications during labor. Moreover, the clinical use of the NT-proBNP test in this field requires further study. [ABSTRACT FROM AUTHOR]
