Analysis of risk factors in angiographically proven coronary artery disease in rural and urban Indian population. Prospective observational multicentre study: Kashmir Heart Survey.

Background: The global burden of cardiovascular diseases is increasing rapidly, and changing trends in epidemiological risk factors are identified among diverse Indian population. There has been a significant increase in heart attack deaths over the past 3 years after the COVID-19 pandemic. Are we missing a link? There is an urgent need for studies to confirm any epidemiological shift in coronary artery disease (CAD) risk factors.

Refining Cardiovascular Calcification in the Appraisal of Ischemic Heart.

Background: Even in asymptomatic patients, there is a high association of ischemia on myocardial perfusion scans in those with coronary artery calcification or valvular calcifications. Patients without coronary artery calcifications have exceeding-low rates of cardiovascular events. The absence of cardiovascular calcification, including coronary artery, valvular, and thoracic aorta is a strong negative predictor of myocardial ischemia.

Clinical, Demographic, and Angiographic Profiles of Amarnath Pilgrims Presenting With Acute Coronary Syndrome.

Introduction: The challenges posed by high altitude are particularly significant in terms of cardiovascular health. There are currently no data available on acute coronary syndrome (ACS) among Amarnath pilgrims. The objective of this study was to investigate the clinical and angiographic profiles of ACS among Amarnath pilgrims, focusing on demographic characteristics, risk factors, types of ACS, clinical presentation, angiographic findings, and in-hospital outcomes.

Left ventricular diastolic function and cardiotoxic chemotherapy.

Background: Left ventricular ejection fraction falls when the myocardium has already lost a significant portion of its functional capacity. There are conflicting data on whether diastolic dysfunction precedes systolic dysfunction after cardiotoxic chemotherapy. We aimed to study systolic and diastolic dysfunction after cardiotoxic chemotherapy and whether diastolic dysfunction can predict subsequent risk of systolic dysfunction.

Role of cardiac magnetic resonance imaging in identifying infarct related artery and non-ischemic pathogenesis in patients presenting with non ST elevation myocardial infarction.

Introduction: Identifying an Infarct-related artery (IRA)in Non-STEMI is sometimes tricky. Besides, myocardial infarction with non-obstructive coronary arteries (MINOCA) mimickers are often labeled as myocardial infarction. Late Gadolinium enhancement (LGE) on cardiac MRI can help in identifying IRA besides MINOCA mimickers.

Management of PDA device closure complicated by severe hemolysis by transcatheter retrieval and deployment of new device.

Background: Hemolysis after Patent ductus arteriosus (PDA) device closure is rare. Although in most cases, hemolysis settles on its own; however, in some cases it may not settle spontaneously and may require additional procedures like putting additional coils, gel foam or thrombin instillation, balloon occlusion, or removing it surgically. We report a case of adult PDA device closure who persisted with hemolysis and was managed by transcatheter retrieval.

Safety and efficacy of ARNI (valsartan/sacubitril) vs ACEI (enalapril) in acute heart failure - A prospective observational study.

Objective: To compare the safety and efficacy of valsartan/sacubitril (angiotensin receptor neprilysin inhibitor [ARNI]) against enalapril (angiotensin-converting enzyme inhibitor [ACEI]) in patients with acute heart failure at 6-month follow-up.

Methods: In this prospective, single centre, and observational study conducted between September 2017 and February 2020 in India, patients with acute decompensated heart failure with reduced ejection fraction (<40%) were included. Patients were divided in two groups: valsartan/sacubitril (ARNI) group and enalapril (ACEI).

Effect of Cereclor as Rejuvenator to Enhance the Aging Resistance of Reclaimed Asphalt Pavement Binder.

Asphalt is the most commonly used material for pavement construction around the world, and therefore, it is vital to acquaint a practice that restores the reclaimed asphalt pavement (RAP) binder properties to the required level of performance by adding proper rejuvenators. However, a rejuvenator may perform better in the early stages of its application but may not necessarily perform better in the long run. The aim of this study is to assess the rejuvenation effect on the aging resistance of RAP binder in long-life performance through applying artificial aging.

An Innovation in Pacemaker Lead Implantation via Persistent Left Superior Vena Cava: The "3D Alpha Curve" Stylet.

Persistent left superior vena cava (PLSVC) draining into coronary sinus is typically detected incidentally during transcatheter interventions using left subclavian venous approach. In our experience, we have encountered this anomaly on a few occasions and in all these cases we successfully implanted leads in the right ventricle (RV) by shaping the stylet into a "U-shaped" or "pigtail-shaped" curve. Herein, we report a case of an adult male who underwent successful dual-chamber pacemaker implantation via PLSVC through left axillary venous approach.
