Cardiovascular disease significantly jeopardizes pregnancies in the United States, impacting 1% to 4% of pregnancies annually. Among complications, cardiac arrhythmias are prevalent, posing concerns for maternal and fetal health. The incidence of arrhythmias during pregnancy is rising, partly due to advances in congenital heart surgery and a growing population of women with structural heart disease. While most arrhythmias are benign, the increasing prevalence of more serious arrhythmias warrants a proactive approach. Guidance and reassurance suffice in many cases, but persistent symptoms require cautious use of antiarrhythmic drugs or other therapies for a safe outcome. Managing more serious arrhythmias requires a comprehensive, multidisciplinary approach involving specialists, including maternal-fetal medicine physicians, cardiologists, electrophysiologists, and anesthesiologists., Competing Interests: Kamala Tamirisa is on the Speakers Bureau for Abbott and Sanofi; Estefania Oliveros is funded by a research grant from Johnson and Johnson; Annabelle Santos Volgman is a consultant for Sanofi, Pfizer, Janssen, Novartis, and NIH Clinical Trials and holds stock in Apple, Inc.

Introduction: Balancing antithrombotic therapy for atrial fibrillation (AF) patients undergoing percutaneous coronary intervention (PCI) remains a clinical challenge due to coexisting thrombogenic risks. This review emphasizes the delicate balance required to prevent ischemic events while minimizing bleeding complications, particularly in the context of risk assessment., Areas Covered: This review spans from 2010 to October 2023, exploring the complexities of antithrombotic management for AF patients undergoing PCI. It stresses the need for personalized treatment decisions to optimize antithrombotic therapies effectively., Expert Opinion: The evolving evidence supports double antithrombotic therapy (DAT) over triple antithrombotic therapy (TAT) for these patients, showcasing a more favorable safety profile without compromising efficacy. Non-vitamin K antagonist oral anticoagulant (NOAC)-based DAT strategies exhibit superiority in reducing major bleeding events while effectively preventing ischemic events. Recommendations from the 2023 European Society of Cardiology (ESC) Guidelines advocate for NOAC-based DAT post-PCI, endorsing safer antithrombotic profiles.Challenges persist for specific patient categories requiring both oral anticoagulants and antiplatelets, necessitating personalized approaches. Future advances in intravascular imaging and novel coronary stent technologies offer promising avenues to optimize outcomes and influence antithrombotic strategies in AF-PCI patients.

During the past decade, direct oral anticoagulants (DOACs) have advanced and simplified the prevention and treatment of venous thromboembolism (VTE). However, there remains a high incidence of bleeds, which calls for agents that have a reduced risk of bleeding. Factor XI (FXI) deficiency is associated with lower rates of venous thrombosis and stroke compared to the general population with a lower risk of bleeding. In conjunction with this, phase 2 studies have demonstrated safety and the potential for reduced thrombotic events with FXI inhibitors as compared to currently available medications. The aim of this review is to summarize key data on the clinical pharmacology of FXI, the latest developments in clinical trials of FXI inhibitors, and to describe the efficacy and safety profiles of FXI inhibitors for the prevention of venous and arterial thromboembolism., Competing Interests: Declaration of conflicting interestsDr. Barnes serves on the Board of Directors for the Anticoagulation Forum and as a consultant for Pfizer, Bristol-Myers Squibb, Janssen, Bayer, AstraZeneca, Sanofi, Anthos, Abbott Vascular, and Boston Scientific.

Heparin-induced thrombocytopenia with thrombosis (HITT) is a rare immune reaction to the drug heparin that causes increased blood clotting, putting patients at risk for arterial and venous thromboembolism which can have severe consequences. We present a case of HITT successfully treated with the direct oral anticoagulant (DOAC), edoxaban. A 56-year-old man had surgery to remove a colorectal mass. After discharge, he developed chest discomfort, shortness of breath, and low oxygen levels and was diagnosed with a right-sided lobar pulmonary embolism. His platelet count dropped, his tests confirmed a diagnosis of HITT, and he was initially treated with fondaparinux. After showing clinical and laboratory improvement, he was switched to edoxaban. Despite being diagnosed with colonic adenocarcinoma during follow-up, the patient's platelet count returned to normal, and he did not experience any more blood clots or serious bleeding events. The use of DOACs like edoxaban as potential therapies for HITT is promising; further research is being conducted to evaluate their effectiveness, safety, and potential benefits for treating this acquired high-risk thrombophilia., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose of Review: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. The estimated lifetime risk of developing AF is higher in men; however, due to differences in life expectancy, the overall prevalence is higher among women, particularly in the older age group. Sex differences play an important role in the pathophysiology, presentation, and clinical outcomes of AF. Awareness of these differences minimizes the potential for disparities in AF management. Our review summarizes the current literature on sex differences in AF, including the epidemiology, pathophysiology, risk factors, clinical symptomatology, mechanisms, treatment, and outcomes. We also explore the implications of these differences for clinical practice and future research., Recent Findings: Women are more likely to present with atypical symptoms, have a higher stroke risk, and have a worse quality of life with AF when compared to men. Despite this, they are less likely to receive rhythm control strategies and anticoagulants. The sex-based differences in AF pathology and management might be a combination of inherent biological and hormonal differences, and implicit bias of the research entities and treating clinicians. Our review stresses the need for further sex-specific research in the pathophysiology of AF and opens a dialogue on personalized medicine, where management strategies can be tailored to individual patient characteristics, including sex., (© 2023.

Calcific aortic valve stenosis (CAS), the most prevalent valvular disease worldwide, has been demonstrated to frequently occur in conjunction with coronary artery disease (CAD), the third leading cause of death worldwide. Atherosclerosis has been proven to be the main mechanism involved in CAS and CAD. Evidence also exists that obesity, diabetes, and metabolic syndrome (among others), along with specific genes involved in lipid metabolism, are important risk factors for CAS and CAD, leading to common pathological processes of atherosclerosis in both diseases. Therefore, it has been suggested that CAS could also be used as a marker of CAD. An understanding of the commonalities between the two conditions may improve therapeutic strategies for treating both CAD and CAS. This review explores the common pathogenesis and disparities between CAS and CAD, alongside their etiology. It also discusses clinical implications and provides evidence-based recommendations for the clinical management of both diseases., Competing Interests: Declaration of Competing Interest Authors wish to declare no conflict of interest., (Copyright © 2023 Elsevier Inc.

Purpose of Review: Influenza imparts a significant health burden on the United States and global population. Furthermore, influenza is associated with acute cardiovascular events, including heart failure exacerbations, acute coronary syndromes, strokes, and overall cardiovascular mortality. We review the role of seasonal influenza vaccination in mitigating cardiovascular risk., Recent Findings: A large study assessed the impact of influenza vaccine on cardiovascular outcomes and mortality using the US National Inpatient Sample (NIS) database. This study included 22 634 643 hospitalizations. Vaccination against influenza was associated with a reduction in myocardial infarctions (MI) [relative risk (RR) = 0.84, 95% CI 0.82-0.87, P  < 0.001], transient ischemic attacks (RR = 0.93, 95% CI 0.9-0.96, P  < 0.001), cardiac arrests (RR = 0.36, 95% CI 0.33-0.39, P  < 0.001), strokes (RR = 0.94, 95% CI 0.91-0.97, P  < 0.001), and overall mortality (RR = 0.38, 95% CI 0.36-0.4, P  < 0.001)., Summary: Available data suggests that seasonal influenza vaccination is very effective in mitigating cardiovascular risk. Increasing the rates of influenza vaccination, especially among those with cardiovascular risk factors, is critical in preventing infection and attenuating influenza-related cardiovascular complications and adverse outcomes., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Cardiovascular disease is the leading cause of mortality for women and men. Prior studies have demonstrated the underrepresentation of women in published clinical trials, but no study to date has assessed inclusion of women in late-breaking clinical trials (LBCTs) presented at national meetings. The objective is to characterize the inclusion of women participants in LBCT presented at the 2021 American College of Cardiology (ACC), American Heart Association (AHA), and European Society of Cardiology (ESC) annual meetings and identify trial characteristics associated with improved inclusion. Methods: LBCT presented at the 2021 ACC, AHA, and ESC meetings were identified and the inclusion of women as participants was assessed. The inclusion to prevalence ratio (IPR) was calculated by dividing the percentage of women participants by the percentage of women in the disease population. IPRs <1 indicate underenrollment of women. Of the 68 LBCT, 3 trials were excluded due to lack of subject matter relevance. Results: Inclusion of women ranged from 0% to 71%. Only 47.1% of trials reported sex-specific analyses. The average IPR was 0.76 for all trials and did not vary based on conference, trial center, geographic region, or funding source. The average IPR varied based on subspecialty, with a statistical difference between interventional cardiology and heart failure (0.65 vs. 0.88, p  = 0.02). The average IPR was significantly lower for procedural studies compared with medication trials (0.61 vs. 0.78, p  = 0.008), as well as for studies with mean age <65 and trial size <1500 participants. There was no difference in IPR based on female authorship. Conclusions: LBCT can impact novel drug and device approval, intervention indications, and patient management. Nonetheless, most LBCT underenroll women, particularly, procedural LBCT. In 2021, sex-based enrollment disparities persist, highlighting the need to engage key stakeholders, including funding organizations, national governing bodies, editorial board members, and medical societies, in the creation of a coordinated strategic initiative to advance gender parity. These findings warrant further investigation to increase inclusion of women in trials, including potential enrollment requirements for consideration as LBCT by meeting organizers.

Portal Vein Thrombosis (PVT), a common complication of advanced liver disease, is defined as an obstruction of the portal vein due to thrombus formation that can extend to the superior mesenteric and splenic veins. It was believed that PVT occurred predominantly due to prothrombotic potential. However, recent studies have shown that decreased blood flow related to portal hypertension appears to increase PVT risk as per Virchow's triad. It is well known that there is a higher incidence of PVTs in cirrhosis with a higher MELD and Child Pugh score. The controversy for management of PVTs in cirrhotics lies in the individualized assessment of risks versus benefits of anticoagulation, since these patients have a complex hemostatic profile with both bleeding and procoagulant propensities. In this review, we will systematically compile the etiology, pathophysiology, clinical features, and management of portal vein thrombosis in cirrhosis., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Prakash, Bies, Hassan, Mares and Didia.)

In the United States, about one million people are seen to visit the operating theater for cardiac surgery annually. However, nearly half of these visits result in complications such as renal, neurological, and cardiac injury of varying degrees. Historically, many mechanisms and approaches have been explored in attempts to reduce injuries associated with cardiac surgery and percutaneous procedures. Devices such as cardioplegia, mechanical circulatory support, and other methods have shown promising results in managing and preventing life-threatening cardiac-surgery-related outcomes such as heart failure and cardiogenic shock. Comparably, cardioprotective devices such as TandemHeart, Impella family devices, and venoarterial extracorporeal membrane oxygenation (VA-ECMO) have also been proven to show significant cardioprotection through mechanical support. However, their use as interventional agents in the prevention of hemodynamic changes due to cardiac surgery or percutaneous interventions has been correlated with adverse effects. This can lead to a rebound increased risk of mortality in high-risk patients who undergo cardiac surgery. Further research is necessary to delineate and stratify patients into appropriate cardioprotective device groups. Furthermore, the use of one device over another in terms of efficacy remains controversial and further research is necessary to assess device potential in different settings. Clinical research is also needed regarding novel strategies and targets, such as transcutaneous vagus stimulation and supersaturated oxygen therapy, aimed at reducing mortality among high-risk cardiac surgery patients. This review explores the recent advances regarding the use of cardioprotective devices in patients undergoing percutaneous procedures and cardiac surgery.

Dyslipidemia, specifically elevated low-density lipoprotein (LDL) cholesterol levels, causes atherosclerotic cardiovascular disease (ASCVD) and increases the risk of myocardial infarction and stroke. Statins, a class of drugs that exert their effects by inhibiting HMG-CoA reductase, a key enzyme in the synthesis of cholesterol, have been the mainstay of therapy for the primary prevention of cardiovascular disease and lipids reduction. Statins are associated with side effects, most commonly myopathy and myalgias, despite their proven efficacy. This review explores non-statin lipid-lowering therapies and examines recent advances and emerging research. Over the previous decades, several lipid-lowering therapies, both as monotherapy and adjuncts to statin therapy and lipid-targeting gene therapy, have emerged, thus redefining how we treat dyslipidemia. These drugs include Bile acids sequestrants, Fibrates, Nicotinic acid, Ezetimibe, Bempedoic acid, Volanesoren, Evinacumab, and the PCSK 9 Inhibitors Evolocumab and Alirocumab. Emerging gene-based therapy includes Small interfering RNAs, Antisense oligonucleotides, Adeno-associated virus vectors, CRISPR/Cas9 based therapeutics, and Non-coding RNA therapy. Of all these therapies, Bempedoic acid works most like statins by working through a similar pathway to decrease cholesterol levels. However, it is not associated with myopathy. Overall, although statins continue to be the gold standard, non-statin therapies are set to play an increasingly important role in managing dyslipidemia., (Copyright © 2022 Elsevier Inc.

Purpose of Review: Cardiovascular disease is the most common cause of morbidity and mortality worldwide, and the risk is heightened in the presence of obesity. We review semaglutide, a drug recently approved for chronic weight management in adults with obesity or who are overweight., Recent Findings: On 4 June 2021, the US Food and Drug Administration approved semaglutide injection at 2.4 mg once weekly for chronic weight management in adults with obesity or overweight with at least one weight-related condition such as high blood pressure, type 2 diabetes mellitus, or high cholesterol. This subcutaneous injection is the first approved drug for chronic weight management in adults with general obesity or overweight since 2014. The drug is indicated for weight management in patients with a BMI of 27 kg/m2 or greater who have at least one weight-related ailment or in patients with a BMI of 30 kg/m2 or greater., Summary: Semaglutide offers adults with obesity or overweight a new treatment in conjunction with a weight management program consisting of reduced calorie diet and increased physical activity., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Heart failure is a major cause of morbidity and mortality globally. By the end of this decade, ~8 million Americans will have heart failure with an expenditure of $69.8 billion., Objective: In this narrative review, we evaluate the benefits, potential risks and the role of Mineralocorticoid Receptor Antagonists (MRAs) in the management of both Heart Failure with Preserved Ejection Fraction (HFpEF) and Heart Failure with Reduced Ejection Fraction (HFrEF)., Methods: We performed a comprehensive literature review to assess the available evidence on the role of MRAs in heart failure using the online databases (PubMed, Embase, Scopus, CINAHL and Google Scholar)., Results: Clinical evidence shows that MRAs such as spironolactone and eplerenone reduce mortality and readmissions for patients with HFrEF compared with placebo. Furthermore, one trial reported that MRAs reduce heart failure hospitalization in patients with HFpEF. The American College of Cardiology/American Heart Association Guidelines strongly recommend using MRA in patients with reduced Left Ventricular Ejection Fraction (LVEF) with Class II-IV symptoms, estimated glomerular filtration rate >30 ml/min/1.73 m 2 , and absence of hyperkalemia. Despite this, MRAs are underutilized in the management of heart failure., Conclusions: MRAs improve outcomes in patients with both HFpEF and HFrEF but remain underutilized., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Pulmonary arterial hypertension (PAH) is a devastating cardiovascular disease leading to right heart failure and death if untreated. Medical therapies for PAH have evolved substantially over the last decades and are associated with improvements in functional class, quality of life, and survival. PAH-targeted therapies now consist of multiple inhaled, oral, subcutaneous, and intravenous therapies targeting the phosphodiesterase, guanylate cyclase, endothelin and prostacyclin pathways. Patients with congenital heart disease (CHD) are at high risk of developing PAH and growing evidence exists that PAH-targeted therapy can be beneficial in PAH-CHD. However, the PAH-CHD patient population is challenging to treat due to the heterogeneity and complexity of their cardiac lesions and associated comorbidities. Furthermore, most high-quality randomized placebo-controlled trials investigating the effects of PAH-targeted therapies only included a minority of PAH-CHD patients. Few randomized, controlled trials have investigated the effects of PAH-targeted therapy in pre-specified PAH-CHD populations. Consequently, the results of these clinical trials cannot be extrapolated broadly to the PAH-CHD population. This review summarizes the data from high-quality clinical PAH treatment trials with a specific focus on the PAH-CHD population., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Chronic total occlusion (CTO) of a coronary artery is typically defined as a completely occluded artery without any antegrade flow and a duration of at least 3 months. We reviewed the current literature describing the optimal management of CTO including the role of revascularization and choice of modality, i.e., percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery. Databases (PubMed, the Cochrane Library, Embase, EBSCO, Web of Science, and CINAHL) were searched and relevant studies of patients with CTO were selected for review. The prevalence of coronary artery CTOs is approximately 25% among patients undergoing coronary angiography for angina. Available data suggests that PCI of CTO can be a technically complex procedure with relatively lower success rates compared with non-CTO PCI and typically associated with a higher complication rate especially at nonspecialized centers. Furthermore, successful CTO-PCI is associated with symptomatic improvement but does not appear to improve mortality, myocardial infarction, stroke, and repeat revascularization rates. Based on contemporary data, PCI of CTO lesions may be considered in patients with incapacitating angina despite treatment with optimal guideline-directed medical therapy and in whom based on coronary anatomy there is a reasonable chance of technical success with an acceptable risk., Competing Interests: Conflict of Interest Authors confirm that they have no conflict of interest., (International College of Angiology.

Atrial fibrillation (AFIB) is the most common heart rhythm abnormality and is associated with significant morbidity and mortality. While the treatment of AFIB involves strategies of rate with or without rhythm control, it is also essential to strategize appropriate therapies to prevent thromboembolic complications arising from AFIB. Previously, anticoagulation was the main treatment option which exposed patients to higher than usual risk of bleeding. However, with the advent of new technology, novel therapeutic options aimed at surgical or percutaneous exclusion or occlusion of the left atrial appendage in preventing thromboembolic complications from AFIB have evolved. This review evaluates recent advances and therapeutic options in treating AFIB with a special focus on both surgical and percutaneous interventions which can reduce and/or eliminate thromboembolic complications of AFIB., Competing Interests: Competing interests: None declared., (© American Federation for Medical Research 2020.

Purpose of Review: To review the clinical evidence on the use of percutaneous coronary intervention (PCI) revascularization options in left main (LM) disease in comparison with coronary artery bypass graft (CABG). Coronary artery disease (CAD) involving the LM is associated with high morbidity and mortality. Though CABG remains the gold standard for complex CAD involving the LM artery, recent trials have shown a trend towards non-inferiority of the LM PCI when compared with CABG in certain subset of patients., Recent Findings: Two recent major randomized trials compared the outcomes of PCI versus CABG in the LM and multi-vessel disease with LM involvement. The NOBLE trial included patients with all range of Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) scores and utilized biolimus drug-eluting stent (DES). The trial concluded that MACCE (major adverse cardiac and cerebrovascular event) was significantly higher with PCI (28%) when compared with CABG (18%) but overall stroke and motility were not different. EXCEL trial evaluated the same treatment option in low to intermediate SYNTAX score population with third-generation everolimus DES platform as PCI option. Results showed no significant differences in the composite primary endpoints of death, stroke, and myocardial infarction (MI) at the end of 30 days (22% versus 19.2%, p = 0.13), although repeat revascularization was higher in PCI group (16.9% versus 10%). Recent evidence suggests that PCI is an acceptable alternative to treat symptomatic LM stenosis in select group of patients. In low to medium SYNTAX score, particularly in patients without diabetes mellitus, PCI remains a viable option. Future trials focusing on evaluating subset of patients who would benefit from one particular revascularization option in comparison with other is warranted.

Background: Cooking with biomass fuels on open fires results in exposure to health-damaging pollutants such as carbon monoxide (CO), polycyclic aromatic hydrocarbons (PAHs), and particulate matter., Objective: We compared CO exposures and urinary PAH biomarkers pre- and postintervention with an improved biomass stove, the Patsari stove., Methods: In a subsample of 63 women participating in a randomized controlled trial in central Mexico, we measured personal CO exposure for 8 hr during the day using continuous monitors and passive samplers. In addition, first-morning urine samples obtained the next day were analyzed for monohydroxylated PAH metabolites by gas chromatography/isotope dilution/high-resolution mass spectrometry. Exposure data were collected during the use of an open fire (preintervention) and after installation of the improved stove (postintervention) for 47 women, enabling paired comparisons., Results: Median pre- and postintervention values were 4 and 1 ppm for continuous personal CO and 3 and 1 ppm for passive sampler CO, respectively. Postintervention measurements indicated an average reduction of 42% for hydroxylated metabolites of naphthalene, fluorene, phenanthrene, and pyrene on a whole-weight concentration basis (micrograms per liter of urine), and a 34% reduction on a creatinine-adjusted basis (micrograms per gram of creatinine). Pre- and postintervention geometric mean values for 1-hydroxypyrene were 3.2 and 2.0 μg/g creatinine, respectively., Conclusion: Use of the Patsari stove significantly reduced CO and PAH exposures in women. However, levels of many PAH biomarkers remained higher than those reported among smokers.

Rationale: Exposure to biomass smoke has been related to adverse health effects. In Mexico, one household in four still cooks with biomass fuel, but there has been no evaluation of the health impact of reducing indoor air pollution., Objectives: To evaluate the health impact of the introduction of an improved biomass stove (Patsari; Interdisciplinary Group for Appropriate Rural Technology [GIRA], Patzcuaro, Mexico) in Mexican women., Methods: A randomized controlled trial was conducted in the Central Mexican state of Michoacán. Households were randomized to receive the Patsari stove or keep their traditional open fire. A total of 552 women were followed with monthly visits over 10 months to assess stove use, inquire about respiratory and other symptoms, and obtain lung function measurements. Statistical analysis was conducted using longitudinal models., Measurements and Main Results: Adherence to the intervention was low (50%). Women who reported using the Patsari stove most of the time compared with those using the open fire had significantly lower risk of respiratory symptoms (relative risk [RR], 0.77; 95% confidence interval [CI], 0.62-0.95 for cough and RR, 0.29; 95% CI, 0.11-0.77 for wheezing) adjusted for confounders. Similar results were found for other respiratory symptoms as well as for eye discomfort, headache, and back pain. Actual use of the Patsari stove was associated with a lower FEV(1) decline (31 ml) compared with the open fire use (62 ml) over 1 year of follow-up (P = 0.012) for women 20 years of age and older, adjusting for confounders., Conclusions: The use of the Patsari stove was significantly associated with a reduction of symptoms and of lung function decline comparable to smoking cessation.
