Takotsubo syndrome (TTS) is characterized by acute and reversible left ventricular dysfunction with apical ballooning arising during acute stress situations. Acute ischemic stroke (AIS) is one of the known triggers of TTS; however, the impact of TTS on in-hospital outcomes of AIS remains unexplored. We utilized data from the National Inpatient Sample (2007–2014) to identify admissions for AIS with TTS and evaluated the temporal trends, baseline characteristics, in-hospital complications, length of stay, and all-cause mortality. Survey multivariable logistic regression was used to compute adjusted odds ratios (OR) and 95% confidence intervals (CI). An estimated 2242 (0.4%) TTS cases were identified among AIS hospitalizations (N = 4,392,471). The frequency of TTS was higher in elderly, white, and female patients. After adjustment for confounders, TTS incidence in AIS was associated with higher odds of in-hospital complications including cardiogenic shock (OR 8.84, CI 4.07–19.17, P < 0.001), cardiac arrest (OR 3.17, CI 1.57–6.42, P = 0.001), and venous thromboembolism (OR 1.68, CI 1.14–2.47, P = 0.008). Moreover, AIS hospitalizations with TTS showed higher odds of developing respiratory failure (OR 3.13, CI 2.42–4.05, P < 0.001) and requiring mechanical ventilation/intubation (OR 4.09, CI 3.14–5.32, P < 0.001) compared to the non-TTS cohort. The AIS-TTS cohort had a longer length of stay (8.59 vs 5.22 days), and their mortality rate was twice (10.2% vs 5.1%; P < 0.001) that of those without TTS. In conclusion, the prevalence of TTS in AIS remained ∼20 times higher than in the general inpatient population and predisposed AIS patients to worse inpatient outcomes. Further studies are needed to evaluate the impact of TTS on long-term outcomes in AIS. [ABSTRACT FROM AUTHOR]

Background: Tumor lysis syndrome (TLS) is a life‐threatening oncologic emergency associated with fatal complications including arrhythmia. The epidemiology and mortality outcomes of arrhythmia in TLS are scarcely studied in the literature. Methods: We used the National Inpatient Sample (NIS) to study the prevalence and outcome of arrhythmia in patients hospitalized with TLS (ICD‐9 code 277.88) from 2009 to 2014. Baseline characteristics, burden of arrhythmia, and pertinent outcomes were analyzed. Multivariable regression analysis was performed to identify the impact of underlying malignancy in predicting TLS‐related mortality. Results: A total of 9034 cases of arrhythmia among 37 861 TLS patients were identified. More than half of the arrhythmia cases (67%) were found among white old (>65) males admitted to large bed size and urban teaching hospitals. Arrhythmic cohort showed higher frequency of comorbidities such as fluid‐electrolyte disturbances, hypertension, congestive heart failure, renal failure, dyslipidemia, diabetes, pulmonary circulatory disorders, chronic pulmonary disease, coagulopathy, and deficiency anemia. The most common malignancies were leukemia, lymphoma, metastatic tumor, and solid tumor without metastasis. We found significantly higher odds of in‐hospital mortality among patients with TLS compared to general inpatient population on unadjusted (OR 9.69, 95% CI: 9.27‐10.13, P <.001) and adjusted (OR 4.62, 95% CI: 4.39‐4.85) multivariable analyses. Overall in‐hospital mortality (32% vs 21.3%), median length of stay (11 days vs 9 days), and hospital charges were higher among arrhythmic than nonarrhythmic patients. Conclusion: With the availability of more advanced cancer therapy in the US, nearly one in four inpatient encounters of TLS had arrhythmia. Arrhythmia in TLS patients was associated with higher odds of mortality and increased resource utilization. Therefore, strategies to improve the supportive care of TLS patients plus timely diagnosis and treatment of arrhythmia are of utmost importance in reducing mortality and health‐care cost.

The impact of coronavirus disease, 2019 (COVID-19), has been profound. Though COVID-19 primarily affects the respiratory system, it has also been associated with a wide range of cardiovascular (CV) manifestations portending extremely poor prognosis. The principal hypothesis for CV involvement is through direct myocardial infection and systemic inflammation. We conducted a systematic review of the current literature to provide a foundation for understanding the CV manifestations and outcomes of COVID-19. PubMed and EMBASE databases were electronically searched from the inception of the databases through 27 April 2020. A second literature review was conducted to include major trials and guidelines that were published after the initial search but before submission. The inclusion criteria for studies to be eligible were case reports, case series, and observation studies reporting CV outcomes among patients with COVID-19 infection. This review of the current COVID-19 disease and CV outcomes literature revealed a myriad of CV manifestations with potential avenues for treatment and prevention. Future studies are required to understand on a more mechanistic level the effect of COVID-19 on the myocardium and thus provide avenues to improve mortality and morbidity. [ABSTRACT FROM AUTHOR]

Data on utilization and safety of mitral Transcatheter Edge-to-Edge Repair (TEER) among hypertrophic cardiomyopathy (HCM) patients is limited. Our study aimed to assess the national utilization, safety, and clinical outcomes of TEER procedures among HCM patients using a nationwide real-world cohort. HCM patients undergoing TEER hospitalizations between 2015–2020 were identified using ICD-10 (International Classification of Diseases, (ICD-10-CM/PCS). HCM-TEER and HCM No-TEER formed the two comparison groups. Demographic characteristics, baseline comorbidities, procedural complications, inpatient mortality, length of stay (LOS), and cost of hospitalization were compared between the propensity-matched cohorts. Numeric values of 10 or less were not reported per NIS data use agreements. A total of 39,625 weighted cases of TEER were identified from 2015–2020. Of the included patients, 335 patients had the HCM diagnosis. The median age of the HCM-TEER group was 74 (70–79) vs. 79 (72–85) for the no-TEER cohort. The TEER procedure was more frequently performed among Caucasians (86.57%) and females (53.73%). The TEER procedure among HCM patients had similar in-hospital mortality (Adjusted odds ratio: aOR 1.50, 95% CI [0.68–3.29]; p = 0.30) and net adverse cardiac events (NACE) (aOR 1.16, 95% CI [0.73–1.85]; p = 0.51). TEER among HCM was associated with higher odds of gastrointestinal/hematological (aOR 2.33, 95% CI [1.29–4.19]; p = 0.003) complications. However, the odds of cardiac complications (aOR 0.57, 95% CI [0.33–0.96]; p = 0.03) were not higher. The median length of stay was similar in both the groups (median: 2 vs. 2, p = 0.74), although TEER among HCM was associated with higher costs of hospitalization ($44729.36 vs. $40513.82, p < 0.01). TEER is a minimally invasive procedure and could be a safe option for symptomatic HCM patients with significant MR who are poor surgical candidates. Mitral TEER among HCM has been increasingly utilized in recent years in the United States more commonly in obstructive HCM and is associated with no difference in mortality and net adverse cardiac events but higher odds for gastrointestinal/hematological complications than non-HCM patients.

There is a paucity of data about the sex differences in acute coronary syndrome (ACS) outcomes in patients with prior mediastinal radiation. The National Inpatient Sample database from years 2009 to 2020 were queried for ACS hospitalizations of patients with prior mediastinal radiation. The primary outcome was MACCE (major cardiovascular events), and secondary outcomes included other clinical outcomes. A total of 23,385 hospitalizations for ACS with prior mediastinal radiation exposure ([15,904 (68.01%) females, and 7481 (31.99%) males]) were included in analysis. Males were slightly younger than females (median, age (70 [62-78] vs 72 [64-80]). Female patients with ACS had a higher burden of hypertension (80.82% vs 73.55%), diabetes mellitus (33% vs 28.35%), hyperlipidemia (66.09% vs 62.2%), obesity (17.02% vs 8.6%) however, males had a higher burden of peripheral vascular disease (18.29% vs 12.51%), congestive heart failure (41.8% vs 39.35%) and smoking (70.33% vs 46.92%). After propensity matching, primary outcome MACCE was higher in males (20.85% vs 13.29%, aOR: 1.80 95% CI (1.65-1.96), P < 0.0001) along with cardiogenic shock (8.74% vs 2.42%, aOR: 1.77 95% CI (1.55-2.02), P < 0.0001) and mechanical circulatory support use (aOR: 1.48 95% CI [1.29 -1.71], P < 0.0001). We observed no differences in the length of hospital stay, however total hospitalization cost was higher in males. This nationwide analysis showed significant disparities in outcomes among male and female ACS patients with prior mediastinal radiation history, with increasing trend in hospitalization for ACS among males and females but decreasing mortality among females.

Background: Cardiovascular disease is the major cause of mortality in end stage renal disease (ESRD) patients on dialysis and myocardial infarction constitutes almost 20% of such deaths. We assessed the trends, characteristics and in-hospital outcomes in patients with ESRD.Methods: We used national inpatient sample (NIS) to identify patients with ESRD presenting with ST-segment elevation myocardial infarction (STEMI) for calendar years 2012-2016. Multiple logistic regression analysis and propensity matched data was used to compare outcomes for the purpose of our study.Results: Patients on dialysis who presented with STEMI were less likely to be treated with emergent reperfusion therapies including percutaneous coronary intervention, bypass graft surgery and thrombolytics with in first 24 h. In propensity-matched cohort, the mortality was nearly double in patients who have ESRD compared to patients without ESRD (29.7% vs. 15.9%, p < 0.01). In-patient morbidity such as utilization of tracheostomy, mechanical ventilation and feeding tubes was also more prevalent in propensity matched ESRD cohort. In multivariate regression analysis, ESRD remains a strong predictor of increased mortality in STEMI patients (OR 2.65, 95% CI, 2.57-2.75, p < 0.01).Conclusion: Our study showed low utilization of evidence-based prompt reperfusion therapies in ESRD patients with STEMI along with concomitant increased poor outcomes and resource utilization. Future research specifically targeting this extremely high-risk patient population is needed to identify the role of prompt reperfusion therapies in improving outcomes in these patients.

Background: Cardiomyopathy (CDM) in pregnancy is associated with maternal morbidity and mortality., Objectives: To explore trends and clinical outcomes in CDM subtypes during delivery hospitalizations., Methods: We used the National Inpatient Sample database to identify delivery hospitalizations between 2005-2020 by CDM subtypes: peripartum (PPCM), dilated (DCM), hypertrophic (HCM), and restrictive (RCM). Maternal and fetal outcomes were identified using International Classification of Diseases, 9th and 10th Revision, Clinical Modification codes. Baseline characteristics and temporal trends of CDM subtypes were analyzed. Maternal cardiovascular, pregnancy, and fetal outcomes were evaluated by CDM subtype using univariate logistic regression. The primary outcome was in-hospital mortality., Results: During 2005-2020, 37,125 out of 61,811,842 delivery hospitalizations were complicated by CDM. Among CDM-related delivery hospitalizations, the most prevalent were DCM (46%), followed by PPCM (45.6%), HCM (4.6%), and RCM (3.9%). The rates of in-hospital mortality (1.7%), adverse cardiovascular events such as acute heart failure (17%), cardiogenic shock (3.4%), and cardiac arrest (3.1%), and adverse pregnancy outcomes such as preeclampsia (14.2%) and preterm labor (11%), were highest among PPCM (all p < 0.0001). The prevalence of PPCM (49.1% to 38.5%) decreased while the prevalence of HCM (2.7% to 8.8%) and DCM (48% to 52.2%) increased over time., Conclusions: Over a 15-year period, PPCM had higher rates of in-hospital mortality, cardiovascular events, and adverse pregnancy outcomes compared to other CDM subtypes. While the prevalence of PPCM decreased over time, the prevalence of HCM and DCM increased. Hence, further research on cardiomyopathies during pregnancy and prospective studies on this vulnerable patient cohort are urgently needed., Competing Interests: Declaration of competing interest Dr. Sharma is supported by the AHA grant 979,462.

Background: Rural-urban disparities in peripartum cardiomyopathy (PPCM) are not well known. We examined rural-urban differences in maternal, fetal, and cardiovascular outcomes in PPCM during delivery hospitalizations., Methods: We used 2003-2020 data from the National Inpatient Sample for delivery hospitalizations in individuals with PPCM. The 9th and 10th editions of the International Classification of Diseases were used to identify PPCM and cardiovascular, maternal, and fetal outcomes. Rural and urban hospitalizations for PPCM were 1:1 propensity score-matched using relevant clinical and sociodemographic variables. Odds of in-hospital mortality were assessed using logistic regression., Results: Among 72,880 delivery hospitalizations with PPCM, 4,571 occurred in rural locations, while 68,309 occurred in urban locations. After propensity matching, there were a total of 4,571 rural-urban pairs. There was significantly higher in-hospital mortality in urban compared to rural hospitalizations (adjusted OR 1.54, 95% CI 1.10-1.89). Urban PPCM hospitalizations had significantly higher cardiogenic shock (2.9% vs. 1.3%), mechanical circulatory support (1.0% vs. 0.6%), cardiac arrest (2.3% vs. 0.9%), and VT/VF (4.5% vs. 2.1%, all p <.05). Additionally, urban PPCM hospitalizations had worse maternal and fetal outcomes as compared to rural hospitalizations, including higher preterm delivery, gestational diabetes, and fetal death (all p<.05). Notably, significantly more rural individuals were transferred to a short-term hospital (including tertiary care centers) compared to urban individuals (13.5% vs. 3.2%, p<.0001)., Conclusions: There are significant rural-urban disparities in delivery hospitalizations with PPCM. Worse outcomes were associated with urban hospitalizations, while rural PPCM hospitalizations were associated with increased transfers, suggesting inadequate resources and advanced sickness., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Limited data are available regarding in-hospital outcomes of transcatheter aortic valve implantation (TAVI) in the octogenarian population with chronic kidney disease (CKD). We sought to study the cardiovascular outcomes of TAVI in CKD hospitalization with different stages at the national cohort registry. We used the National Inpatient Sample database to compare TAVI CKD low-grade (LG) (stage I to IIIa, b) versus TAVI CKD high-grade (HG) (stage IV to V) in octogenarians. Outcomes such as inpatient mortality, cardiogenic shock, new permanent pacemaker implantation, acute kidney injury), sudden cardiac arrest, mechanical circulatory support, major bleeding, transfusion, and resource utilization were compared between the 2 cohorts. A total of 74,766 octogenarian patients (TAVI CKD-HG n = 12,220; TAVI CKD-LG n = 62,545) were included in our study. On matched analysis, TAVI CKD-HG had higher odds of in-hospital mortality (adjusted odds ratio [aOR] 2.18, 95% confidence interval [CI] 1.0-2.5, p <0.0001), cardiogenic shock (aOR 1.22, 95% CI 1.07 to 1.39, p = 0.0019), permanent pacemaker implantation (aOR 1.14, 95% CI 1.06 to 1.23, p = 0.0006), acute kidney injury (aOR 1.19, 95% CI 1.13 to 1.27, p <0.0001), sudden cardiac arrest (aOR 1.32, 95% CI 1.09 to 1.61, p = 0.004), major bleeding (aOR 1.1, 95% CI 1.006 to 1.22, p <0.0368) and higher rates of blood transfusion (aOR 1.62, 95% CI 1.5 to 1.75, p <0.0001) when compared with the TAVI CKD-LG cohort. However, there was no statistically significant difference in the odds of cerebrovascular accident and mechanical circulatory support use between the 2 groups., Competing Interests: Declaration of Competing Interest The authors have no competing interests to declare., (Copyright © 2023 Elsevier Inc.

End-stage renal disease (ESRD) and atrial fibrillation (AF) are commonly encountered, with ESRD itself serving as a well-established risk factor for AF. 1 The 2018 AF guidelines have recommended apixaban across all the spectrums of renal impairment, including patients on hemodialysis (HD), and the 2019 American Heart Association/American College of Cardiology/Heart Rhythm Society updated guidelines have suggested careful consideration of reduced dose of direct oral anticoagulants (DOACs) in patients with ESRD. 2 , 3 The current data on the safety and efficacy of warfarin versus DOACs in patients with AF with ESRD and HD is variable. This study aimed to perform a study-level meta-analysis to evaluate the effectiveness and safety of warfarin and DOACs in patients with AF who require dialysis., Competing Interests: Declaration of Competing Interest The authors have no competing interests to declare., (Copyright © 2023 Elsevier Inc.

The management of concomitant mitral valve (MV) disease in patients with hypertrophic cardiomyopathy (HCM) remains controversial. The 2020 American Heart Association/American College of Cardiology HCM guidelines recommend that MV replacement (MVR) at the time of myectomy should not be performed for the sole purpose of relieving outflow obstruction. At the national level, limited data exist on the surgical outcomes of MV repair/replacement in patients with HCM who underwent septal myectomy (SM). Hospitalizations of patients with HCM who underwent SM between 2005 and 2020 were identified using International Classification of Diseases, Ninth and Tenth Revision codes (International Classification of Diseases, Ninth and Tenth Revision Clinical Modification/Procedure Coding System). The 3 comparison cohorts were SM alone, MV repair, and MVR with concomitant SM. After propensity matching, 2 cohorts, SM + MVR versus SM + MV repair, were studied for surgical outcomes. Demographic characteristics, baseline co-morbidities, procedural complications, inpatient mortality, length of stay, and cost of hospitalization were compared between the propensity-matched cohorts. A total of 16,797 SM procedures were identified from 2005 to 2020. Among them, 11,470 hospitalizations had SM alone (68.2%), SM + MVR was seen in 3,101 (18.4%), and SM + MV repair comprised 2,226 (13.2%). After propensity matching, the MVR and MV repair formed the matched cohorts of 1,857. There were no significant differences in the odds of cardiogenic shock (adjusted odds ratio [aOR] 0.88, 95% confidence interval [CI] 0.63 to 1.24, p = 0.49), mechanical circulatory support requirement (aOR 0.58, 95% CI 0.37 to 0.90, p = 0.015), stroke (aOR 1.27, 95% CI 0.81 to 1.99, p = 0.29), and major bleeding (aOR 0.52, 95% CI 0.34 to 0.79, p = 0.0026) between the comparison groups. MVR, compared with MV repair, was associated with a higher risk of procedural mortality (8.02% vs 3.18%, aOR 2.98, 95% CI 2.05 to 4.33, p <0.0001), complete heart block (16.36% vs 12.15%, aOR 1.76, 95% CI 1.44 to 2.12, p <0.0001), and the need for permanent pacemaker (16.39% vs 10.62%, aOR 1.83, 95% CI 1.41 to 2.38, p <0.0001). The total length of hospital stay and median hospitalization cost was higher in the MVR group. SM in HCM concomitant with MVR is associated with higher procedural mortality and in-hospital complication risk. These real-world data support the 2020 American Heart Association/American College of Cardiology guidelines that in patients who are candidates for surgical myectomy, MVR should not be performed as part of the operative strategy for relieving outflow obstruction in HCM., Competing Interests: Declaration of Competing Interest The authors have no competing interests to declare., (Copyright © 2023 Elsevier Inc.

Transcatheter aortic valve replacement (TAVR) utilization is increasing, along with procedural success. Coronary angiography is frequently performed before the TAVR procedure for coronary artery disease workup. Chronic total occlusion (CTO) of the coronary artery shares common risk factors with aortic stenosis and could be challenging, especially in terms of procedural safety. The outcomes of TAVR among patients with concomitant CTO are not extensively studied. We analyzed the National Inpatient Sample database between October 2015 and December 2020 to evaluate the clinical characteristics, procedural safety, and outcomes among patients who underwent TAVR who had concomitant CTO lesions. A total of 304,330 TAVRs were performed between 2015 and 2020, 5,235 of which (1.72%) were in patients with TAVR-CTO and 299,095 (98.28%) in those with TAVR-no CTO. After propensity matching, there was no difference in the odds of in-hospital mortality (adjusted odds ratio [aOR] 1.28, 95% confidence interval [CI] 0.94 to 1.75, p = 0.11). However, TAVR-CTO was associated with an increased incidence of acute myocardial infarction (aOR 1.27, 95% CI 1.05 to 1.53, p = 0.01), cardiac arrest (aOR, 2.60, 95% CI 1.64 to 4.11, p <0.0001), and need for mechanical circulatory support (aOR 2.6, 95% CI 1.88 to 3.59, p <0.0001). There was no difference in the incidence of stroke, major bleeding, complete heart block, or requirement for permanent pacemaker between the 2 groups. However, the TAVR-CTO cohort had a slightly greater length of stay and total hospitalization cost. TAVR is a relatively safe procedure among those with concomitant CTO lesions; however, it is associated with a greater incidence of acute myocardial infarction, cardiac arrest, and requirement for mechanical circulatory support., Competing Interests: Declaration of Competing Interest The authors have no competing interests to declare., (Copyright © 2023 Elsevier Inc.

Transradial access (TRA) and transulnar access (TUA) are in close vicinity, but TRA is the preferred intervention route. The cardiovascular outcomes and access site complications of TUA and TRA are understudied. Databases, including MEDLINE and Cochrane Central registry, were queried to find studies comparing safety outcomes of both procedures. The outcome of interest was in-hospital mortality and access site bleeding. Secondary outcomes were all-cause major adverse cardiovascular events, crossover rate, artery spasm, access site large hematoma, and access site complications between TUA and TRA. A random-effect model was used with regression to report unadjusted odds ratios (ORs) by limiting confounders and effect modifiers, using software STATA V.17. A total of 4,796 patients in 8 studies were included in our analysis (TUA = 2,420 [50.4%] and TRA = 2,376 [49.6%]). The average age was 61.3 and 60.1 years and the patients predominantly male (69.2% vs 68.4%) for TUA and TRA, respectively. TUA had lower rates of local access site bleeding (OR 0.58, 95% confidence interval 0.34 to 0.97, I 2  = 1.89%, p = 0.04) but higher crossover rate (OR 1.80, 95% confidence interval 1.04 to 3.11, I 2  = 75.37%, p = 0.04) than did TRA. There was no difference in in-hospital mortality, all-cause major adverse cardiovascular events, arterial spasm, and large hematoma between both cohorts. Furthermore, there was no difference in procedural time, fluoroscopy time, and contrast volume used between TUA and TRA. TUA is a safer approach, associated with lower access site bleeding but higher crossover rates, than TRA. Further prospective studies are needed to evaluate the safety and long-term outcomes of both procedures., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2023 Elsevier Inc.

Utilization of radio-opaque coronary artery bypass graft markers is known to decrease the amount of contrast dye required to complete the procedure. The practice of marking bypass grafts varies significantly among surgeons. Limited data exist comparing the outcomes of percutaneous coronary intervention with and without coronary artery bypass graft (CABG) markers. We sought to explore the impact of proximal radio-opaque markers placed during CABG in subsequent percutaneous coronary intervention procedural risks. In our understanding of the current literature, this is the first meta-analysis conducted to evaluate the association between procedural angiographic metrics and CABG radio-opaque markers. We performed a query of MEDLINE and Scopus databases through August 2022 to identify relevant studies evaluating procedural metrics among patients with previous CABG with and without radio-opaque markers who underwent angiography. The primary outcomes of interest were fluoroscopy time, amount of contrast, and duration of angiography. We identified a total of 4 studies with 2,046 patients with CABG (CABG with markers n = 688, CABG without markers n = 1,518). 2-5 Total fluoroscopy time was significantly reduced among patients with CABG markers compared with those with no markers (odds ratio [OR] -3.63, p <0.0001). The duration of angiography (OR -36.39, p >0.10) was reduced, although the result was not statistically significant. However, the amount of contrast utilization was significantly reduced (OR -33.41, p <0.0001). In patients who underwent CABG with radio-opaque markers, angiographic procedural metrics were improved, including reduced fluoroscopic time and the amount of contrast agent required compared with no markers., (Copyright © 2023 Elsevier Inc.

Background: In the last two decades, risk factors, prevalence, and mortality due to coronary artery disease in young adults are on the rise. We sought to assess the prevalence, trends, and economic burden of ventricular tachycardia (VT) hospitalizations in young adults (< 45 years), further stratified by race and gender., Methods: The Nationwide Inpatient Sample was explored for hospitalizations with VT in patients (< 45 years) between 2005 and 2018 and divided among 3 groups of the quadrennial period using validated International Classification of Diseases (ICD) 9 th and 10 th revision Clinical Modification (CM) codes. The Pearson chi-square test and Wilcoxon rank-sum were used for categorical and continuous variables, respectively. We assessed the temporal trends of mortality in VT hospitalizations and trends of VT hospitalization stratified by age, sex, and race by using Joinpoint regression analysis. The primary outcome was in-hospital mortality trends. Secondary outcomes were trends of hospital stay in days, cost of care in US dollars, cardiac arrest, and discharge disposition., Results: Out of 5,156,326 patients admitted with VT between 2005 and 2018, 309,636 were young adults. Among them, 102,433 were admitted between 2005 and 2009 (mean age 36.1 ± 6.99; 61% male, 58.5% White), 109,591 between 2010 and 2014 (mean age 35.5 ± 7.16; 59% male, 54.2% White), and 97,495 between 2015 and 2018 (mean age 35.4 ± 7.00; 60% male, 52.3% White) (p < 0.07). In the young adults with VT, all-cause mortality was 7.37% from 2005 to 2009, 7.85% from 2010 to 2014 (6.5% relative increase from 2005 to 2009), and 8.98% from 2015 to 2018 (relative increase of 14.4% from 2010 to 2014) (p < 0.0001). Similarly, risk of cardiac arrest was on the rise (6.15% from 2005 to 2009 to 7.77% in 2010-2014 and 9.97% in 2015-2018). Inflation-adjusted cost increased over the years [$12,177 in 2005-2009; $13,249 in 2010-2014; $15,807 in 2015-2018; p < 0.0001)]., Conclusions: VT hospitalizations and related all-cause mortality, and healthcare utilization costs in young adults are on the rise in the study period. Hospitalization burden related to VT and poor outcomes were more notable for Black adults. Further studies are required for targeted screening and preventative measures in young adults., (© 2022.

Aims: The relative safety and efficacy of de-escalation, extended duration (ED) (&gt;12-months), and standard dual antiplatelet therapy for 12-months (DAPT-12) in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) remains controversial., Methods and Results: Online databases were queried to identify relevant randomized control trials (RCTs). ED-DAPT, high-potency (HP) DAPT, shorter duration (SD) DAPT, and low-dose (LD) DAPT were compared with DAPT-12. A trial sequential, bivariate, influential, and frequentist network meta-analysis (NMA) was performed to determine the pooled estimates. A total of 30 RCTs comprising 81 208 (40 839 experimental, 40 369 control arm) patients with CAD were included in the quantitative analysis. On NMA, compared with DAPT-12, all types of de-escalation, HP-DAPT-12, and ED-DAPT strategies had a statistically non-significant difference in the incidence of MACE at a median follow-up of 1-year. Similarly, there was no significant difference in the incidence of stroke, stent thrombosis, target lesion revascularization (TLR), target vessel revascularization (TVR), and all-cause mortality between DAPT-12 and all other strategies. The network estimates showed a significantly lower incidence of major bleeding with DAPT for 3-months followed by P2Y12-inhibitor monotherapy (RR 0.62, 95% CI 0.45-0.84), while a higher risk of bleeding with HP-DAPT for 12 months (RR 1.55, 95% CI 1.16-2.06). The net clinical benefit and rankograms also favoured DAPT-3 (P2Y12) and discouraged the use of HP-DAPT-12 and ED-DAPT. A subgroup analysis of 19 RCTs restricted to patients who presented with acute coronary syndrome (ACS) mirrored the findings of pooled analysis. A sensitivity analysis revealed no influence of any individual study or individual strategy on net ischemic estimates. The trial sequential analysis (TSA) illustrated a consistently non-significant difference at the interim analysis of trials, reaching the futility area for MACE, while the cumulative Z-values line surpassed the monitoring boundary as well as the required information size for major bleeding favouring de-escalation strategy., Conclusion: DAPT for three months followed by ticagrelor-only and use of aspirin + clopidogrel after a short period of high potency DAPT appears to be a safe strategy for treating post-PCI patients. However, given the methodological limitations and inclusion of a small number of trials in novel de-escalation strategies, these findings need validation by future large scale RCTs., (© The Author(s) 2022.

Background: Limited data is available on the comparison of outcomes of transradial (TR) and transfemoral (TF) access for percutaneous coronary intervention (PCI) in patients with end-stage stage renal disease (ESRD)., Methods: Online databases were queried to compare cardiovascular outcomes among TR. and TF in ESRD patients. The outcomes assessed included differences in mortality, cerebrovascular accidents (CVA), periprocedural myocardial infarction (MI), bleeding, transfusion, and periprocedural cardiogenic shock (CS). Unadjusted odds ratios (OR) were calculated using a random-effect effect model., Results: A total of 6 studies including 7,607 patients (TR-PCI = 1,288; TF-PCI = 6,319) were included. The overall mean age was 67.7 years, while the mean age for TR-PCI and TF-PCI was 69.7 years and 67.9 years, respectively. TR-PCI was associated with lower incidence of mortality (OR 0.46 95 % CI 0.30-0.70, p < 0.05, I2 0.00 %), bleeding (OR 0.45 95 % CI 0.29, 0.68, p < 0.05, I2 3.48 %), and transfusion requirement (OR 0.52 95 % CI 0.40, 0.67, p < 0.05, I2 0.00 %) (Fig. 1). There were no differences among TR-PCI and TF-PCI for periprocedural MI, periprocedural CS, and CVA outcomes., Conclusion: TR access was associated with lower mortality, bleeding, and transfusion requirement as compared to TF access in patients with ESRD undergoing PCI., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 Published by Elsevier B.V.)

Takotsubo syndrome (TTS) is characterized by acute and reversible left ventricular dysfunction with apical ballooning arising during acute stress situations. Acute ischemic stroke (AIS) is one of the known triggers of TTS; however, the impact of TTS on in-hospital outcomes of AIS remains unexplored. We utilized data from the National Inpatient Sample (2007-2014) to identify admissions for AIS with TTS and evaluated the temporal trends, baseline characteristics, in-hospital complications, length of stay, and all-cause mortality. Survey multivariable logistic regression was used to compute adjusted odds ratios (OR) and 95% confidence intervals (CI). An estimated 2242 (0.4%) TTS cases were identified among AIS hospitalizations (N = 4,392,471). The frequency of TTS was higher in elderly, white, and female patients. After adjustment for confounders, TTS incidence in AIS was associated with higher odds of in-hospital complications including cardiogenic shock (OR 8.84, CI 4.07-19.17, P  < 0.001), cardiac arrest (OR 3.17, CI 1.57-6.42, P  = 0.001), and venous thromboembolism (OR 1.68, CI 1.14-2.47, P  = 0.008). Moreover, AIS hospitalizations with TTS showed higher odds of developing respiratory failure (OR 3.13, CI 2.42-4.05, P  < 0.001) and requiring mechanical ventilation/intubation (OR 4.09, CI 3.14-5.32, P  < 0.001) compared to the non-TTS cohort. The AIS-TTS cohort had a longer length of stay (8.59 vs 5.22 days), and their mortality rate was twice (10.2% vs 5.1%; P  < 0.001) that of those without TTS. In conclusion, the prevalence of TTS in AIS remained ∼20 times higher than in the general inpatient population and predisposed AIS patients to worse inpatient outcomes. Further studies are needed to evaluate the impact of TTS on long-term outcomes in AIS., (Copyright © 2021 Baylor University Medical Center.)

Aims: To analyze the sex-based differences in the prevalence of cardiovascular disease risk factors and outcomes in older patients with prediabetes using demographically matched national cohorts of hospitalized patients aged ≥65 years., Methods: We queried the 2007-2014 National Inpatient Database to identify older patients (>65 years) admitted with prediabetes using ICD-9 Clinical Modification codes. The older patients were then subcategorized based on sex. Comparative analyses of their baseline characteristics, the prevalence of cardiovascular(CV) disease comorbidities, hospitalization outcomes, and mortality rates were performed on propensity-matched cohorts for demographics., Results: A total of 1,197,978 older patients with prediabetes (599,223 males; mean age 75years and 598,755 females; mean age 76years) were identified. Higher admission rates were found commonly among older white males (84.1%) and females (81.7%). Prediabetic older males showed a higher frequency of cardiovascular comorbidities compared to females. Prediabetic older males had higher all-cause in-hospital mortality (4.2% vs. 3.6%, p < 0.001), acute myocardial infarction (7.0% vs. 4.7%, p < 0.001), arrhythmia (36.3% vs. 30.5%, p < 0.001), stroke (4.8% vs. 4.6%, p < 0.001), venous thromboembolism (3.3% vs. 3.0%, p < 0.001) and percutaneous coronary intervention (3.1% vs. 1.5%, p < 0.001) compared to females., Conclusions: Our analysis revealed that among older patients hospitalized with prediabetes, males suffered worse in-hospital CV outcomes and survival rates compared to females., (Copyright © 2020 Primary Care Diabetes Europe.
