The Evolving Paradigm of Revascularization in Ischemic Cardiomyopathy: from Recovery of Systolic Function to Protection Against Future Ischemic Events.

Purpose Of Review: We aim to reevaluate how the assessment of myocardial viability can guide optimal treatment strategies for patients with ischemic cardiomyopathy (ICM) based on a more contemporary understanding of the mechanism of benefit of revascularization.

Recent Findings: The assessment of viability in left ventricular (LV) segments with diminished contraction has been proposed as key to predict the benefit of revascularization and, therefore, as a requisite for the selection of patients to undergo this form of treatment. However, data from prospective trials have diverged from earlier retrospective studies.

Nationwide Analysis of Cardiac Arrest Outcomes During the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic had a significant impact on the chain of survival following cardiac arrest. However, large population-based reports of COVID-19 in patients hospitalized after cardiac arrest are limited. The National Inpatient Sample database was queried for cardiac arrest admissions during 2020 in the United States.

Pharmacotherapies in Heart Failure With Preserved Ejection Fraction: A Systematic Review and Network Meta-Analysis.

Various pharmacotherapies exist for heart failure with preserved ejection fraction (HFpEF), but with unclear comparative efficacy. We searched EMBASE, Medline, and Cochrane Library from inception through August 2021 for all randomized clinical trials in HFpEF (EF >40%) that evaluated beta-blockers, mineralocorticoid receptor antagonist (MRA), angiotensin-converting enzyme inhibitors (ACE), angiotensin receptor blockers (ARB), angiotensin receptor-neprilysin inhibitor (ARNI), and sodium-glucose cotransporter-2 inhibitors (SGLT2i). Outcomes assessed were cardiovascular mortality, all-cause mortality, and HF hospitalization.

The Challenge of Pregnancy in Women With Hypertrophic Cardiomyopathy.

Hypertrophic cardiomyopathy is a genetic disease that frequently presents at a young age. Pregnancy represents a state of high physiological stress to the cardiovascular system. Thus, pregnant women with hypertrophic cardiomyopathy face the potential for higher morbidity and, therefore, their management may become a significant challenge when complications develop.

Ecpella 5.5: An Evolution in the Management of Mechanical Circulatory Support.

There are several endovascular options for temporary mechanical circulatory support in patients with refractory cardiogenic shock. These devices are often utilized in tandem to provide maximal support, including the combination of venoarterial extracorporeal membrane oxygenation with the Impella device, termed ECPELLA. An underappreciated characteristic of mechanical circulatory support is whether they provide cardiac "replacement" and/or cardiac "assistance.

Trends in 10-Year Predicted Risk of Cardiovascular Disease Associated With Food Insecurity, 2007-2016.

Introduction: Consumption of a healthy diet improves cardiovascular (CV) risk factors and reduces the development of cardiovascular disease (CVD). Food insecure (FIS) adults often consume an unhealthy diet, which can promote obesity, type 2 diabetes mellitus (T2DM), hypertension (HTN), and hyperlipidemia (HLD). The Supplemental Nutrition Assistance Program (SNAP) is designed to combat food insecurity by increasing access to healthy foods.

Cost-Effectiveness of Coronary Artery Bypass Surgery Versus Medicine in Ischemic Cardiomyopathy: The STICH Randomized Clinical Trial.

Background: The STICH Randomized Clinical Trial (Surgical Treatment for Ischemic Heart Failure) demonstrated that coronary artery bypass grafting (CABG) reduced all-cause mortality rates out to 10 years compared with medical therapy alone (MED) in patients with ischemic cardiomyopathy and reduced left ventricular function (ejection fraction ≤35%). We examined the economic implications of these results.

Methods: We used a decision-analytic patient-level simulation model to estimate the lifetime costs and benefits of CABG and MED using patient-level resource use and clinical data collected in the STICH trial.

Differences in Short-Term Outcomes and Hospital-Based Resource Utilization Between Septal Reduction Strategies for Hypertrophic Obstructive Cardiomyopathy.

Background: Given clinical equipoise in a subset of obstructive hypertrophic cardiomyopathy (OHCM) patients who are candidates for both alcohol septal ablation (ASA) or septal myectomy (SM), other considerations such as cost, readmissions, and hospital length of stay (LOS) may be important to optimize healthcare resource utilization and inform shared decision making.

Methods: In this retrospective observational analysis of the United States Nationwide Readmissions Database years 2012-2014, we identified adults who underwent isolated septal reduction (SR) for OHCM. We studied the differences in short-term outcomes (inpatient mortality and 90-day readmission rate) and in-hospital resource utilization (LOS and costs) between the SR strategies.

Influence of diabetes mellitus interactions with cardiovascular risk factors on post-myocardial infarction heart failure hospitalizations.

Objective: There is a paucity of information regarding how cardiovascular risk factors (RF) modulate the impact of diabetes mellitus (DM) on the heart failure hospitalization (HFH) risk following an acute myocardial infarction (AMI).

Methods: Adult survivors of an AMI were retrospectively identified from the 2014 US Nationwide Readmissions Database. The impact of DM on the risk for a 6-month HFH was studied in subgroups of RFs using multivariable logistic regression to adjust for baseline risk differences.

Myocardial Viability Assessment Before Surgical Revascularization in Ischemic Cardiomyopathy: JACC Review Topic of the Week.

Ischemic cardiomyopathy results from the combination of scar with fibrosis replacement and areas of dysfunctional but viable myocardium that may improve contractile function with revascularization. Observational studies reported that only patients with substantial amounts of myocardial viability had better outcomes following surgical revascularization. Accordingly, dedicated noninvasive techniques have evolved to quantify viable myocardium with the objective of selecting patients for this form of therapeutic intervention.

Mental health disorders among patients with acute myocardial infarction in the United States.

Objective: To assess the prevalence, temporal trends and sex- and racial/ethnic differences in the burden of mental health disorders (MHD) and outcomes among patients with myocardial infarction (MI) in the United States.

Methods: Using the National Inpatient Sample Database, we evaluated a contemporary cohort of patients hospitalized for acute MI in the United States over 10 years period from 2008 to 2017. We used multivariable logistic regression analysis for in-hospital outcomes, yearly trends and estimated annual percent change (APC) in odds of MHD among MI patients.

Role of MicroRNA in Heart Transplant.

The need for noninvasive biomarkers for diagnostic, prognostic, and therapeutic purposes is increasingly being recognized in the field of heart transplantation. MicroRNAs are a class of novel biomarkers that control gene expression and influence cellular functions, including differentiation, proliferation, and functional regulation of the immune system. They can be detected in the serum, plasma, and urine and may serve as early noninvasive biomarkers for various disease processes.

Left Ventricular Assist Device Implantation in Hypertrophic and Restrictive Cardiomyopathy: A Systematic Review.

Left ventricular assist device (LVAD) implantation in patients with advanced heart failure due to hypertrophic or restrictive cardiomyopathy (HCM/RCM) presents technical and physiologic challenges. We conducted a systematic review of observational studies to evaluate the utilization and clinical outcomes associated with LVAD implantation in patients with HCM/RCM and compared these to patients with dilated or ischemic cardiomyopathy (DCM/ICM). We searched MEDLINE, EMBASE, and Scopus from inception through May 2019 and included appropriate studies describing the use of an LVAD in patients with HCM/RCM.

Optimal medical therapy with or without surgical revascularization and long-term outcomes in ischemic cardiomyopathy.

Objectives: Optimal medical therapy in patients with heart failure and coronary artery disease is associated with improved outcomes. However, whether this association is influenced by the performance of coronary artery bypass grafting is less well established. Thus, the aim of this study was to determine the possible relationship between coronary artery bypass grafting and optimal medical therapy and its effect on the outcomes of patients with ischemic cardiomyopathy.

Radial vs. Femoral Access for Percutaneous Coronary Artery Intervention in Patients With ST-Elevation Myocardial Infarction.

Background: We aimed to compare the safety and efficacy of transradial vs transfemoral access for coronary angiography and intervention in patients presenting with ST-segment elevation myocardial infarction (STEMI) without cardiogenic shock.

Methods: PubMed, Embase and Cochrane Central were searched for randomized controlled trials (RCTs) comparing outcomes of STEMI patients who underwent transradial angiography (TRA) compared to transfemoral angiography (TFA). Our outcomes of interest were major adverse cardiac events (MACE), all-cause mortality, severe bleeding, access site bleeding, myocardial infarction, stroke, and major vascular complications.

Rate, Causes, and Predictors of 30-Day Readmission Following Hospitalization for Acute Pericarditis.

Background: Acute pericarditis is a frequent cause of hospitalization in the United States. Although recurrence of this condition is common, few studies have investigated hospital readmissions in this patient population.

Methods: We queried the National Readmission Database for the years 2016 and 2017 to identify adult admissions for acute pericarditis, and analyzed the data for 30-day readmission.
