The Uric Acid-to-High-Density Lipoprotein Cholesterol Ratio: A New Biomarker for Predicting Arrhythmia Recurrence After Atrial Fibrillation Ablation.

We aimed to assess the uric acid-to-high-density lipoprotein cholesterol (HDL-C) ratio (UHR) and several other parameters with respect to their performance in detecting recurrence among patients with atrial fibrillation (AF) who underwent ablation. This retrospective cohort study analyzed data from patients who underwent radiofrequency or cryoablation for paroxysmal, persistent, or long persistent AF between September 2021 and September 2023. After ablation, patients were monitored for 24 h, with an ECG Holter used for symptomatic cases.

Despite implementation of new interventional techniques and therapeutic advances, elderly patients with acute coronary syndrome (ACS) continue to be susceptible to in-hospital bleeding compared with younger ones. Thus, we investigated the incidence of in-hospital bleeding events and associated risk factors in elderly (≥ 75°years) ACS patients. We also wanted to define the bleeding sites, characteristics, and associated mortality.

Hepatitis C infection is associated with increased coronary artery atherosclerosis defined by modified Reardon severity score system.

Background: The link between arteriosclerotic disease in the carotid or coronary artery and chronic hepatitis C virus (HCV) infection has been shown in some studies although other studies have produced contrary results. However, the effect of chronic HCV infection on the extension or severity of coronary artery disease (CAD) has not been determined so the aim of the present study was to determine the effect of HCV infection on the severity of CAD.

Methods And Results: The study group comprised 139 HCV seropositive and 225 HCV seronegative patients with angiographically documented CAD.

Systolic total narrowing of left anterior descending coronary artery and flow interruption secondary to myocardial bridge: a rare case report and review of literature.

No pathological signs were recorded upon physical examination. The admission electrocardiogram (ECG) recorded during chest pain showed a large anterior wall myocardial infarction.

Sympathetic overactivity in patients with pulmonary stenosis and improvement after percutaneous balloon valvuloplasty.

Objective: Percutaneous balloon valvulotomy (PBV) is the procedure of choice for the treatment of valvular pulmonary stenosis (PS) with similar results comparable to surgical valvotomy but less invasive.

Methods And Results: Twenty-seven consecutive patients with PS being evaluated for PBV were enrolled in the study. Peak instantaneous transvalvular gradient, right ventricle (RV) diameter, mean atrial pressures, RV systolic pressure (RVSP), pro-brain natriuretic peptide (proBNP) levels significantly decreased immediately after PBV.

Relationship of admission QRS duration and changes in QRS duration with myocardial reperfusion in patients with acute ST segment elevation myocardial infarction (STEMI) treated with fibrinolytic therapy.

Background: Although ischemia induced QRS complex changes have been described previously, their relationship with impaired reperfusion, which is known to be associated with poor clinical outcomes, is not clear.
