Acoustic cardiography is a completely new technology, it has great advantages in the rapid diagnosis of cardiovascular diseases. The purpose of this study was to investigate the clinical value of the fourth heart sound (S4), cardiac systolic dysfunction index (SDI), and the cardiac cycle time-corrected electromechanical activation time (EMATc) in the prediction of post-percutaneous coronary intervention (PCI) early ventricular remodeling (EVR) in patients with acute myocardial infarction (AMI). We recruited 161 patients with AMI of 72-h post-PCI, including 44 EVR patients with left ventricular ejection fraction (LVEF) < 50% and 117 Non-EVR patients (normal left ventricular systolic function group, LVEF ≥ 50%).

Objective: Ghrelin is a polypeptide that is closely associated with many cardiovascular diseases, such as hypertension, atherosclerosis, and heart failure. This article aims to understand the expression of ghrelin in patients with atrial fibrillation (AF).
Methods: A total of 182 patients with non-valvular heart diseases were recruited, among whom 92 had AF and 90 had sinus arrhythmia (SA).
Article Synopsis
- - The study investigates how low potassium levels (hypokalemia) affect the electrical behavior of the heart's left ventricle in rabbits, particularly focusing on ventricular repolarization and the potential risk for dangerous heart rhythms (malignant ventricular arrhythmia).
- - Twenty rabbits were divided into control (normal potassium) and hypokalemic groups to test differences in electrical properties like action potential duration and ventricular fibrillation threshold, revealing significant alterations in the hypokalemic group.
- - Results showed that hypokalemia prolonged repolarization duration and reduced the voltage required to induce fibrillation, indicating an increased risk for serious heart arrhythmias, especially associated with changes in specific protein expression related to heart muscle function.
