Abstract

Patients with hypertension who develop atrial premature complexes (APCs) are at a particularly high risk for atrial fibrillation (AF). We sought to identify medications and modifiable risk factors that could reduce the risk of AF imposed by presence of APCs in such a high risk group. This analysis included 4,331 participants with treated hypertension from the Reasons for Geographic and Racial Differences in Stroke study who were free of AF and cardiovascular disease at the time of enrollment (2003-2007). APCs were detected in 8.2% (n = 356) of the participants at baseline. During a median follow-up of 9.4 years, 9.9% (n = 429) of the participants developed AF. Participants with APCs, compared with those without, were more than twice as likely to develop AF (Odds ratio [95% confidence interval]: 2.36[1.75, 3.19]). This association was significantly weaker in statin users than nonusers (Odds ratio [95% confidence interval]:1.42[0.81,2.48] vs 3.01[2.11,4.32], respectively; interaction p-value = 0.02), and in angiotensin-II receptor blocker users than nonusers (Odds ratio [95% confidence interval]:1.31[0.66,2.61] vs 2.78[1.99,3.89], respectively; interaction p-value = 0.05). Borderline weaker associations between APCs and AF were a...Continue Reading

Cardiovascular Disorder in Diabetes

Diabetes is associated with an increased risk of cardiovascular disorders and heart failure. Discover the latest research here.

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.

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.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

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.
