Pregnancy is associated with major structural and hemodynamic changes in the cardiovascular system that predispose women to an increased risk of atrial fibrillation. While these changes generally resolve after parturition, the impact of subsequent pregnancies on the risk of atrial fibrillation is unknown. We searched through PubMed for studies that have investigated the impact of multiparity on the risk of atrial fibrillation. The following Medical Subject Headings terms were used: ([repeated pregnancies] OR parity) AND ([Atrial fibrillation] OR AF). Studies with complete data were included in the current study. Out of 135 studies identified through the prespecified criteria, we selected 2 studies with relevant data. Increasing number of pregnancies was associated with an increased risk of atrial fibrillation in a dose-response relationship. Our systematic review suggests that multiparity is associated with an increased risk of atrial fibrillation. More studies are warranted to elucidate the association between repeated pregnancies and atrial fibrillation.

In this study, we compared the effects of various doses of dexmedetomidine on the incidence of atrial fibrillation following cardiac surgery in adults. 224 adult patients who underwent elective cardiac surgery were randomly assigned to two groups. The DEX0.

Introduction: Off-pump coronary artery bypass graft surgery (OPCAB) has been suggested as superior to on-pump coronary artery bypass graft surgery (ONCAB) in certain high-risk subgroups, but its benefit in patients with chronic obstructive pulmonary disease (COPD) remains controversial. This meta-analysis aimed to evaluate OPCAB versus ONCAB outcomes in COPD patients.

Methods: We followed PRISMA guidelines and searched PubMed, Embase, and the Cochrane Library in August 2024 for studies comparing OPCAB and ONCAB in COPD patients.

Stroke is one of the most common causes of disability in older adults. It remains a common cause of death and permanent functional limitation in individuals who are older than 80 years. Approximately 50% of all strokes occur in people over the age of 75, and 30% in those over 85.

Cardiovascular Disease-Specific Responses to Autonomic Denervation.

January 2025

Department of Cardiovascular Surgery, General Hospital of Northern Theater Command, Shenyang, Liaoning, China. Electronic address:

Background: Calcium-mediated autonomic denervation has been shown to suppress postoperative atrial fibrillation (POAF) after coronary artery bypass grafting.

Objectives: This study sought to evaluate whether similar autonomic denervation can prevent POAF after mitral or aortic valve surgeries.

Methods: This research consisted of 2 single-center, randomized, double-blind, sham-controlled trials: CAP-AF2 (Calcium Autonomic Denervation Prevents Postoperative Atrial Fibrillation in Patients Undergoing Isolated Mitral Valve Surgery for Mitral Regurgitation) for mitral valve (MV) surgery and CAP-AF3 (Calcium Autonomic Denervation Prevents Postoperative Atrial Fibrillation in Patients Undergoing Isolated Aortic Valve Surgery) for aortic valve surgery.
