Primary Prevention of Atrial Fibrillation - The Path Untread

Journal of Atrial Fibrillation

Abstract

The prevalence and incidence of atrial fibrillation (AF) is on the rapid rise. To slow down the AF epidemic, effective primary prevention strategies need to be instituted. Unfortunately, this is an area that has not been well-explored. There is a multitude of risk factors that predispose to the development of AF. Of these, the most common from an epidemiologic perspective are advanced age, hypertension, diabetes, ischemic heart disease, and heart failure. The first-line pharmacologic therapies for these predisposing conditions (e.g. beta blockers, renin-angiotensin system inhibitors, statins, and omega-3 fatty acids) appear to also have potential roles in the primary prevention of AF. Definitive data, however, is lacking as to efficacy of these drugs for this particular purpose. Large-scale, high-quality randomized clinical trials on AF primary preventive strategies are urgently required in order to guide clinical practice. For now, adherence to the guideline-based therapies of each individual risk factor appears to be the most reasonable approach for the primary prevention of AF.

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.

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.
