Objective: Inflammation along with oxidative stress has an important role in the pathophysiology of unstable angina which leads to acute myocardial infarction, arrhythmias and eventually heart failure. Curcumin has anti-inflammatory and anti-oxidant effects and thereby, it may reduce cardiovascular complications. This randomized controlled trial aimed to investigate the effects of curcumin on t...

Introduction: Inhibition of renin angiotensin system represents an important approach in the management of cardiovascular diseases. The aim of this study was to explore the effects of pretreatment with non-hypotensive dose of angiotensin converting enzyme (ACE) inhibitor, ramiprilat and angiotensin type 1 (AT1) receptor blocker, losartan on myocardial infarct size and arrhythmias in a rat mo...

Aims: Ischemic heart disease is the most prevalent cause of mortality in current populations. In recent years, many researchers have focused on plants to discover new natural therapeutic agents. The aim of this study was to evaluate the antiarrhythmic effect of the ethanolic extract of pomegranate mesocarp on rat isolated heart following myocardial ischemia and reperfusion. Materials & Methods...

this study was conducted to assess the incidence of abnormalities of ventricular depolarization (late potentials) in children with sinus rhythm after open heart surgery and their relation to spontaneous ventricular tachycardia. open heart surgery, particularly operations involving ventriculotomy, may predispose patients to the development of ventricular tachycardia (vt) or ventricular fibrillat...

Introduction: Particulate matter (PM) increases the risk of heart disorders. Gallic acid (GA) with strong antioxidant properties has shown an effective role in reducing the complications of various diseases. The aim of this study was to evaluate the protective effect of Gallic acid in preventing cardiac arrhythmias due to exposure to particulate matter. Methods: In this study, 40 rats were pla...

Tachycardia is common in the pediatric age group. The most commonly seen arrhythmias in children are sinus tachycardia. However, supraventricular tachycardia is the most common tachyarrhythmia that necessitates treatment. Ventricular tachycardia is rare in healthy children but may be associated with sudden cardiac death.  The important risk factors that predispose children for arrhythmias inclu...

Objective To investigate the mechanism of ventricular dilation-induced arrhythmias by dilating isolated rat hearts. Methods Isolated rat hearts were perfused by Langerdorff method. After equilibration, 80 hearts were randomly divided into four groups as follows: (1) control group (n=20), (2) Ca2+ preconditioning (CPC) group (n=20), (3) streptomycin group (n=20), and (4) CPC + streptomycin group...

Objective(s) This study aimed to examine whether acetyl-L-carnitine (ALC) was able to reduce cardiac arrhythmias and infarct size in the ischemic-reperfused isolated rat heart. Materials and Methods The isolated hearts were mounted on a Langendorff apparatus then perfused by a modified Krebs-Henseleit solution during 30 min regional ischemia and 120 min reperfusion (control) or by enriched K...
