Abstract

The aim of this study was to examine the bidirectional association between atrial fibrillation and congestive heart failure (CHF) in older adults. We studied the association of atrial fibrillation at entry with incident CHF (N = 5281; 85% white, 42% male) and the association of CHF at entry with incident atrial fibrillation (N = 5233; 85% white, 42% male) in the Cardiovascular Health Study (CHS). Baseline atrial fibrillation was identified during the study electrocardiogram and by self-reported history, and incident cases were identified during subsequent study electrocardiograms and hospitalization data. Baseline CHF was identified by self-reported history and adjudication of medical records, and incident cases were identified using hospitalization data. Cox regression was used to compute hazard ratios and 95% confidence intervals (CIs) for the association between atrial fibrillation and incident CHF, and CHF and incident atrial fibrillation, separately. Over a median follow-up of 12.6 years, 534 (10%) participants developed atrial fibrillation. CHF was associated with an increased risk of atrial fibrillation (hazard ratio 2.0, 95% CI 1.4, 3.0). A total of 1692 (32%) participants developed CHF over a median follow-up of 11.7 y...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.
