Article Abstract
Purpose: This study evaluated the use of a wearable, patch-based cardiac rhythm monitoring device in detecting postoperative atrial fibrillation (POAF) among cardiac surgical patients within 30 days after hospital discharge.
Description: From the SEARCH-AF (The Post-Surgical Enhanced Monitoring for Cardiac Arrhythmias and Atrial Fibrillation) CardioLink-1 trial, this study examined rates of POAF according to surgery type and the incremental value of continuous cardiac rhythm monitoring among patients who underwent valve surgery. The primary outcome was cumulative atrial fibrillation or atrial flutter lasting for ≥6 minutes detected by continuous monitoring or atrial fibrillation or atrial flutter documented by a 12-lead electrocardiogram within 30 days of randomization.
Evaluation: The primary outcome occurred in 8.2%, 13.5%, and 21.2% of patients who underwent isolated coronary artery bypass grafting (CABG), isolated valve surgery, and combined CABG and valve surgery. Relative to patients who underwent isolated CABG, those patients who had valve surgery were more likely to experience POAF. A higher diagnostic yield was obtained when the patch-based cardiac rhythm monitor was applied in patients who underwent valve surgery.
Conclusions: Use of a wearable, patch-based cardiac monitoring device was an effective detection strategy among patients undergoing valve surgery, given their higher risk of developing POAF.

Aims: Atrial fibrillation (AF) may be associated with adverse influenza-related outcomes. We assessed the relative vaccine effectiveness (rVE) of high-dose (HD-IIV) vs. standard-dose (SD-IIV) inactivated influenza vaccination against cardiovascular and all-cause hospitalizations and all-cause mortality according to history of AF.

Background: Postoperative atrial fibrillation (POAF) commonly occurs following surgical repair of degenerative mitral regurgitation (DMR) and is associated with unfavorable outcomes. This study aimed to identify preoperative risk factors for acute POAF in patients undergoing mitral valve repair for DMR, with a specific focus on the role of preoperative echocardiography.
Methods: A retrospective study was conducted involving 1127 DMR patients who underwent mitral valve repair between 2017 and 2022.

Background: Depression is a highly prevalent mental disorder worldwide and is often accompanied by various somatic symptoms. Clinical studies have suggested a close association between depression and cardiac electrophysiological instability, particularly sudden cardiac death (SCD) and arrhythmias. Therefore, this review systematically evaluated the association between depression and the risks of SCD, atrial fibrillation (AF), and ventricular arrhythmias.
