A Nomogram utilizing ECG P-wave parameters to predict recurrence risk following catheter ablation in paroxysmal atrial fibrillation.
J Cardiothorac Surg
January 2025
Department of Cardiology, Fujian Medical University Union Hospital, Fujian Heart Medical Center, Fujian Institute of Coronary Heart Disease, Fujian Clinical Medical Research Center for Heart and Macrovascular Disease, Fuzhou, 350001, China.
Objective: The objective of this study is to assess the predictive utility of perioperative P-wave parameters in patients with paroxysmal atrial fibrillation (PAF) undergoing catheter ablation, and to develop a predictive model using these parameters.
Methods: A total of 213 patients with PAF undergoing catheter ablation were retrospectively analyzed. P-wave parameters were measured within 3 days preoperatively and on the day postoperatively to determine their predictive significance for postoperative PAF recurrence.
Apixaban versus aspirin for stroke prevention in people with subclinical atrial fibrillation and a history of stroke or transient ischaemic attack: subgroup analysis of the ARTESiA randomised controlled trial.
Lancet Neurol
February 2025
Department of Medicine, McMaster University, Population Health Research Institute, Hamilton, ON, Canada.
Background: People with subclinical atrial fibrillation are at increased risk of stroke, albeit to a lesser extent than those with clinical atrial fibrillation, leading to an ongoing debate regarding the benefit of anticoagulation in these individuals. In the ARTESiA trial, the direct-acting oral anticoagulant apixaban reduced stroke or systemic embolism compared with aspirin in people with subclinical atrial fibrillation, but the risk of major bleeding was increased with apixaban. In a prespecified subgroup analysis of ARTESiA, we tested the hypothesis that people with subclinical atrial fibrillation and a history of stroke or transient ischaemic attack, who are known to have an increased risk of recurrent stroke, would show a greater benefit from oral anticoagulation for secondary stroke prevention compared with those without a history of stroke or transient ischaemic attack.

Ann Med
December 2025
Heart Centre, Turku University Hospital, Turku, Finland.
Background: Several randomized controlled trials (RCTs) have investigated the benefits of atrial fibrillation (AF) screening. However, since none have shown a significant reduction in stroke rates, the impact of screening on clinical outcomes remains uncertain.
Materials And Methods: We conducted a systematic review and meta-analysis of RCTs reporting clinical outcomes of systematic AF screening in participants without known AF.
Mechanistic Insights into Melatonin's Antiarrhythmic Effects in Acute Ischemia-Reperfusion-Injured Rabbit Hearts Undergoing Therapeutic Hypothermia.
Int J Mol Sci
January 2025
Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, Taoyuan Branch, Taoyuan 33304, Taiwan.
The electrophysiological mechanisms underlying melatonin's actions and the electrophysiological consequences of superimposed therapeutic hypothermia (TH) in preventing cardiac ischemia-reperfusion (IR) injury-induced arrhythmias remain largely unknown. This study aimed to unveil these issues using acute IR-injured hearts. Rabbits were divided into heart failure (HF), HF+melatonin, control, and control+melatonin groups.
