Abstract Background: Diastolic heart failure comprises 50 percent of cases of heart failure. The implications of increased levels of cardiac troponin I (CTnI) on congestive heart failure with preserved systolic function (AHF PEF) have been poorly evaluated. We hypothesized that its level might be elevated in AHF PEF so this evaluation was done in patients referred to Taleghani hospital with ...

Acute myocardial infarction causes depression of left ventricular function, but the capacity of the ventricle to recover from such an injury remains unknown. This problem was explored by measuring left ventricular function in eight intact conscious dogs before, 1 hr after, and again 6-8 days after myocardial infarction. Acute myocardial infarction was produced using a technique which entails gr...

Background and Aim: Heart failure is one of the most prevalent diseases with high mortality and disability. Beta blockers are among basic drugs treating the disorder and leading to reduction in cardiovascular mortality, and improvement of symptoms and left ventricular function. Regarding the increasing prevalence of this disease, the present study was carried out to compare carvedilol with meto...

Introduction: The present study is aimed to evaluate electrophysiological remodeling of atrioventricular (AV) node and ventricular conduction during experimental atrial fibrillation (AF) model in isolated heart of cirrhotic rats. Methods: Cirrhosis-induced electrophysiological remodeling was evaluated in 24 isolated retrogradely perfused rat hearts in 2 groups (control and cirrhotic). Cirrho...

LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...

Introduction:Asthma is the most common chronic inflammatory condition affecting the lower airways among children. Asthma may influence right ventricular (RV) function and patients may develop right ventricular hypertrophy, pulmonary hypertension and cor pulmonale. The main objective of this study is to determine RV dysfunction in asymptomatic asthmatic children as detected by ti...

The effects of a large arteriovenous fistula on left and right ventricular hemodynamics and cardiac myocyte size were examined in adult rats at 1 week and 1 month after surgery. Cardiac output, left ventricular function, and right ventricular function were evaluated before obtaining isolated myocytes for cell size measurements. Average heart weight increased 35% at 1 week and 86% at 1 month in ...

BACKGROUND The relation between left ventricular (LV) remodeling and ventricular arrhythmias after myocardial infarction is poorly documented. We investigated the relations between LV size, hypertrophy, and function and ventricular arrhythmias in 263 patients from the Survival and Ventricular Enlargement (SAVE) study, using quantitative 2D echocardiography and ambulatory ECG monitoring after my...
