Heart failure is common in the elderly population. Approximately 6 to 10 percent of the population 65 years or older have heart failure. Heart failure is the most common reason for hospitalization in elderly patients. Etiology of heart failure is often multifactorial in the elderly. The common causes of heart failure include ischemic heart disease, valvular heart disease, hypertensive heart dis...

BACKGROUND Since only little is known on stem cell therapy in non-ischemic heart failure we wanted to know whether a long-term improvement of cardiac function in non-ischemic heart failure can be achieved by stem cell transplantation. METHODS White male New Zealand rabbits were treated with doxorubicin (3 mg/kg/week; 6 weeks) to induce dilative non-ischemic cardiomyopathy. Thereafter, we obta...

background : the signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. the purpose of this study was to demonstrate the correlation between the filtered qrs duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes an...

BACKGROUND Surgical ventricular restoration is an option in patients with coronary artery disease, heart failure, postinfarction left ventricular aneurysm or ischemic dilated cardiomyopathy with or without ventricular tachycardia. The aims of this study were to investigate survival and re-admission for heart failure and to identify predictors for early and long-term mortality and re-admission a...

patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...

ihd as a modern epidemic of our age is one of the main causes of mortality in iran. this research was done in order to determine the relationship between place of residence and place of occupation (as indicator of air pollution exposures) and other risk factors with ihd. this is a case- control study of ihd involving 191 men aged 45 -70 years. the cases were 91 male patients with myocardial inf...

cardiovascular disease (cad) screening in asymptomatic patients with diabetes mellitus is controversial. an exercise stress test is a safe and effective initial testing for ischemic heart disease (ihd) screening. treadmill stress test is not the best screening method for a particular patient who is not able to exercise, abnormal electrocardiogram (ecg) or positive exercise treadmill test (ett) ...

the use of local anesthesia with lidocaine containing epinephrine in patients with cardiac disease is controversial in the literature. the aim of our study was determining the safety of use the local anesthesia contain epinephrine in patients with ischemic heart disease that undergoing reconstructive surgery. thirty two patients that had known ischemic heart disease and candidate to undergo rec...
