A sphygmomanometer that can detect atrial fibrillation may help to identify asymptomatic patients who might benefit from anticoagulation. Its performance in young people has not been reported. In a school project measuring blood pressure in 60 normal healthy male teenagers (age range 13-18 years; mean±SD 15.0±1.5 years), a Microlife BPA200 blood pressure monitor indicated atrial fibrillation in 11 participants (18%). These participants did not have any personal or family history of heart disease. They had sinus arrhythmia and had significantly lower systolic and diastolic blood pressure, body mass index and waist circumference (all p values <0.05). In young people, atrial fibrillation is very uncommon and false positives are likely. To avoid unnecessary alarm and referrals, this function is best turned off in young patients.

Background: A significant number of patients with atrial fibrillation (AF) on direct oral anticoagulants (DOACs) receives off-label or inappropriate doses. This study examines the prevalence, dosages, and clinical outcomes in AF-patients on DOAC therapy admitted to an emergency department (ED).

Methods: This retrospective single-center observational study utilized data from the Heidelberg Registry of Atrial Fibrillation (HERA-FIB), consecutively including patients with AF presenting to the ED of the University Hospital of Heidelberg from June 2009 to March 2020.

Objective: To explore the risk factors associated with postoperative atrial fibrillation (POAF) after off-pump coronary artery bypass grafting (OPCABG) and to construct a nomogram predictive model.

Methods: In this retrospective cohort study, clinical data of 193 patients who received OPCABG in Huai'an First People's Hospital Affiliated to Nanjing Medical University from June 2021 to November 2023 were retrospectively analyzed. Based on the established diagnosis of POAF, patients were divided into the POAF group (n=75) and the non-POAF group (n=118).

Background: Up to 50% of patients undergoing mitral transcatheter edge-to-edge repair (MTEER) have an indication for left atrial appendage occlusion (LAAO). However, prospective evaluation of this strategy is lacking.

Objectives: The aim of the study was to prospectively evaluate the outcomes of combined LAAO and MTEER.

Atrial fibrillation (AF), the most common sustained arrhythmia, increases stroke and heart failure risks. Here we review genes linked to AF and mechanisms by which they alter AF risk. We highlight gene expression differences between atrial and ventricular cardiomyocytes, regulatory mechanisms responsible for these differences, and their potential contribution to AF.

Background: This article focuses on the effect of body mass index (BMI) on cardiac structure and function in cases with non-valvular atrial fibrillation (NVAF). Only a few articles have investigated the relationship between BMI and the incidence of left atrial thrombus (LAT) or spontaneous echo contrast (SEC) in cases with NVAF.

Methods: This single-center retrospective study was conducted at The First People's Hospital of Changzhou.
