Article Abstract

Atrial fibrillation (AF) is the most common arrhythmia in humans. AF is characterized by irregular and increased atrial muscle activation. This high-frequency activation obliterates the synchronous work of the atria and ventricles, reducing myocardial performance, which can lead to severe heart failure or stroke. The risk of developing atrial fibrillation depends largely on the patient's history. Cardiovascular diseases are considered aging-related pathologies; therefore, deciphering the role of telomeres and DNA methylation (mDNA), two hallmarks of aging, is likely to contribute to a better understanding and prophylaxis of AF. In honor of Prof. Elizabeth Blackburn's 75th birthday, we dedicate this review to the discovery of telomeres and her contribution to research on aging.

Aims: The PARACHUTE-HF trial (NCT04023227) is evaluating the effect of sacubitril/valsartan compared with enalapril on a hierarchical composite of cardiovascular events (cardiovascular death, first heart failure hospitalization), and change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in participants with heart failure and reduced ejection fraction (HFrEF) caused by chronic Chagas cardiomyopathy (CCC). We describe the baseline characteristics of participants in PARACHUTE-HF compared with prior HFrEF trials.

Methods And Results: PARACHUTE-HF, a multicentre, active-controlled, open-label trial, enrolled 922 participants with confirmed CCC, New York Heart Association (NYHA) functional class II-IV, and left ventricular ejection fraction (LVEF) ≤40%.

Background: Atrial fibrillation (AF) and heart failure (HF) frequently coexist in patients, with the development of AF often preceding HF decompensation. We sought to evaluate whether daily remote monitoring of ICD parameters could predict AF occurrence using machine learning techniques in a real-world cohort.

Methods: Data from patients with primary prevention ICDs transmitted daily to the Northwell centralized remote monitoring center between 2012 and 2021 were extracted.

How Often is Multifocal Atrial Tachycardia Mistaken for Atrial Fibrillation in the Emergency Department?

Objective: Multifocal atrial tachycardia (MAT), characterized by an irregularly irregular rhythm, is often regarded as a clinical imitator of atrial fibrillation (AF). We aimed to evaluate the prevalence of MAT misclassification as AF in the emergency department (ED) setting.

Methods: A retrospective analysis of 1,828 ECGs from patients discharged with AF diagnoses over five years.

Background: Fine particulate matter (PM) has been previously linked to cardiovascular diseases (CVDs). PM is a mixture of components, each of which has its own toxicity profile which are not yet well understood. This study explores the relationship between long-term exposure to PM components and hospital admissions with CVDs in the Medicare population.
