Association Between Psychosocial Risk Factors and Readmissions After Acute Myocardial Infarction: Role of COVID-19 Pandemic.

Psychosocial risk factors (PSRFs) are known to be associated with worse cardiovascular (CV) outcomes. However, there are limited data on the impact of PSRFs on readmissions after acute myocardial infarction (AMI) before and during the COVID-19 (Coronavirus Disease 2019) pandemic. Therefore, we aimed to examine this association and whether the effects of PSRFs were amplified during the COVID-19 pandemic. We queried the 2019 and 2020 Nationwide Readmissions Database for adult (age ≥18 years) index admissions with AMI as the primary diagnosis. They were then divided into 2 cohorts based on the presence or absence of ≥1 PSRF and compared across non-COVID-19 (2019) and COVID-19 (2020) time periods. The primary outcome was 30-day all-cause readmissions. Secondary outcomes included cause-specific readmissions (cardiac, noncardiac, AMI, heart failure). Multivariable hierarchical logistic regression was conducted to evaluate differences in outcomes. The study included 380,820 patients with index AMI, of which 214,384 (56%) had ≥1 PSRFs. Patients with PSRFs were younger, more likely to be female, and had a higher prevalence of CV risk factors. Of 30-day all-cause readmissions were higher in patients with PSRFs in both eras. Moreover, noncardiac and heart failure readmissions were also higher in patients with PSRFs admitted with AMI in 2019 and 2020. This study of a nationally representative population magnifies the association of PSRF with more unplanned readmissions after AMI in both pre-COVID-19 and COVID-19 times.

Association of Psychosocial Risk Factors and Outcomes in Heart Failure: Does COVID-19 Affect Outcomes?

Psychosocial risk factors (PSRFs) have emerged as crucial nontraditional risk factors affecting outcomes in patients with heart failure (HF). There is a paucity of data studying these risk factors in HF nationally. Additionally, whether the COVID-19 pandemic impacted outcomes remains unexplored, given the increased psychosocial risk during these times. Our objective is to assess the impact of PSRFs on the outcomes of HF and their comparison across non-COVID-19 and COVID-19 eras. Patients with a diagnosis of HF were selected using the 2019-2020 Nationwide Readmissions Database. Two cohorts were created based on the presence or absence of PSRFs and compared across non-COVID-19 and COVID-19 eras. We examined the association using hierarchical multivariable logistic regression models. A total of 305,955 patients were included, of which 175,348 (57%) had PSRFs. Patients with PSRFs were younger, less likely to be female, and had a higher prevalence of cardiovascular risk factors. All-cause readmissions were higher in patients with PSRFs in both the eras. All-cause mortality [odds ratio, OR 1.15 (1.04-1.27), P = 0.005] and composite of MACE [OR 1.11 (1.06-1.16), P < 0.001] were higher in patients in the non-COVID-19 era. Compared to 2019, patients with PSRFs and HF in 2020 had significantly higher all-cause mortality [OR 1.13 (1.03-1.24), P = 0.009]; however, the composite of MACE was comparable [OR 1.04 (1.00-1.09), P = 0.03]. In conclusion, the presence of PSRFs in patients with HF is associated with a significant increase in all-cause readmissions in COVID-19 and non-COVID-19 eras. The worse outcomes evident in the COVID-19 era highlights the importance of multidisciplinary care in this vulnerable population.

Giant Coronary Artery Aneurysm: A Successful Diagnosis.

Coronary artery aneurysms (CAAs) are rare, with giant CAAs being even rarer. The precise pathophysiology of this phenomenon is still unknown. CAAs are seldom reported life-threatening abnormalities of the cardiovascular system. We herein present a case of a 74-year-old man who presented at the hospital complaining of chest pain. An adenosine thallium scan revealed a small, reversible defect in the inferior wall of the left ventricle extending into the apex, consistent with ischemia. Echocardiography uncovered a large right coronary artery (RCA) aneurysm, measuring 5.6 × 7.5 cm. Diagnostic coronary angiography confirmed the presence of a large RCA aneurysm and aneurysmal dilation of the left anterior descending and circumflex arteries with no flow-limiting lesions. A reversed saphenous vein interposition graft was placed from the ascending aorta to the right posterior descending artery. The RCA aneurysmal sac was resected and sent to pathology, which uncovered myxoid degeneration of the media as well as thrombus formation. No complications were encountered during the procedure. Early diagnosis is vital to avoid fatal complications of CAAs, and therapeutic approaches are currently individualized in view of absence of evidence-based management strategies.

Utilization of the Impella for hemodynamic support during percutaneous intervention and cardiogenic shock: an insight.

INTRODUCTION: Impella is a catheter-based micro-axial flow pump placed across the aortic valve, and it is currently the only percutaneous left ventricular assist device approved for high-risk percutaneous coronary intervention and cardiogenic shock. Areas Covered: Even though several studies have repeatedly demonstrated the excellent hemodynamic profile of Impella in high-risk settings, it remains underutilized. Here we aim to provide an up-to-date summary of the available literature on Impellas use in High risk settings as well as the practical aspects of its usage. Expert Commentary: Percutaneous coronary interventions in high rsk settings have always been challenging for a physician. Impella 2.5 and CP, have been proven safe, cost effective and feasible in High Risk Percutaneous coronary Interventions with an excellent hemodynamic profile.

Anti-arrhythmic medications increase non-cardiac mortality - A meta-analysis of randomized control trials.

INTRODUCTION: Anti-arrhythmic medications (AAMs) are known to increase cardiac mortality significantly due to their pro-arrhythmic effects. However, the effect of AAMs on non-cardiac mortality has not been evaluated. METHODS: Trials published in English language journals from 1990 to 2015 were thoroughly retrieved by searching websites such as PubMed, Medline, Cochrane Library, and Google Scholar. Randomized controlled trials reporting non-cardiac deaths as primary or secondary outcomes were used to compare AAMs to non-arrhythmic therapy (AV nodal blocking agents, implantable cardiovascular defibrillation (ICD), or placebo). Information regarding the sample size, treatment type, baseline characteristics, and outcomes was obtained by using a standardized protocol. The fixed effect model was used to perform meta-analysis, and results were expressed in terms of odds ratio (OR) with confidence interval (CI) of 95%, inter study heterogeneity was assessed using I (2). Intention to treat principle was applied to extract data. RESULTS: Total of 18,728 patients were enrolled in 15 trials; 9359 patients received AAMs and 9369 received non-arrhythmic therapy. AAMs were associated with an increased risk of non-cardiac mortality (OR=1.30, [95% CI: 1.12, 1.50], p=0.0005, I (2) index=24%) and all-cause mortality (OR=1.09, [95% CI: 1.01, 1.18], p=0.04, I (2)=54%) as compared to non-arrhythmic therapy. There was no difference in the cardiac mortality (OR=1.01, [95% CI: 0.92, 1.11], p=0.82, I (2)=53%) or arrhythmic mortality (OR=1.00, [95% CI: 0.89, 1.13], p=0.94, I (2)=64%) between the two groups. CONCLUSION: AAMs are associated with an increased risk of non-cardiac and all-cause mortality. The effect of AAMs, especially amiodarone, on non-cardiac mortality requires further evaluation.
