The purpose of this study is to investigate the effect of the long-term aerobic exercises on cardiac structure, left ventricular stroke volume, and cardiac output. To achieve the purpose of the study, a total of 22 volunteers-including 10 people who have continued regular exercises and 12 people as the control group-were selected as subjects. With regard to data processing, the IBM SPSS Statist...

BACKGROUND Patients with signs and symptoms of heart failure and a normal left ventricular ejection fraction are said to have diastolic heart failure. It has traditionally been thought that the pathophysiological cause of heart failure in these patients is an abnormality in the diastolic properties of the left ventricle; however, this hypothesis remains largely unproven. METHODS We prospectiv...

Aging is associated with profound changes in the structure and function of the heart. A fundamental understanding of these processes, using relevant animal models, is required for effective prevention and treatment of cardiovascular disease in the elderly. Here, we studied cardiac performance in 4- to 5-mo-old (young) and 24- to 26-mo-old (old) Fischer 344 male rats using the Millar pressure-vo...

The relationship between external records of precordial movement and ventricular function has been studied in 61 patients with various cardiac disorders by comparing the records of the apical impulse to the left ventricular volume. A significant correlation between external recordings and the volume data was found in patients with normal or increased ventricular volumes: Patients with a normal ...

To investigate the relationship between diastolic abnormalities and left ventricular hypertrophy, 52 patients with hypertrophic cardiomyopathy (HCM) and 22 normal subjects were studied with digitized M mode echocardiography and two-dimensional echocardiography. Echocardiographic indexes of diastolic function were compared in patients with different extent of left ventricular hypertrophy. Time i...

BACKGROUND Obesity is a chronic and multifactorial disease, associated with increased cardiovascular risk, especially diastolic heart failure. OBJECTIVE To evaluate left ventricular diastolic function in morbidly obese patients in the pre-operative for bariatric surgery, correlating it with cardiovascular risk factors and heart structure. METHODS This is a cross-sectional study with 132 pat...

ABSTRACT Due to the frequency of major thalassemia in our country and cardiac complications secondry to iron overload as one of the most important causes of death in these patients and the absence of any similar study in this region (Kashan city), we studied the cardiac complications in patients with major thalassemia in Kashan in 1999 and 2000. A prospective descriptive study was perf...

Introduction: The correlation between right and left ventricular ejection fractions (RVEF and LVEF, respectively) has been studied in only a small number of patients with a marked decrease in RVEF and LVEF. The aim of the present study was to compare LVEF and RVEF in patients with ischemic heart disease. RVEF and LVEF were measured by Cardiovascular Magnetic Resonance (CMR) imaging. Materials a...

To elucidate the mechanisms by which the new bipyridine inotropic agent milrinone improves cardiac function, we examined multiple indexes of left ventricular diastolic function before and after administration of milrinone to patients with advanced (NYHA class III or IV) congestive heart failure. In 13 patients left ventricular pressure measurements were made with a micromanometer to permit asse...

INTRODUCTION The aim of the study was to evaluate left ventricular cardiac systolic and diastolic functions by echocardiography in multitransfused children and the possible risk of hepatitis C virus infection as an additional factor impairing cardiac functions in these patients. MATERIAL AND METHODS Echocardiographic studies of left ventricular function in 80 multitransfused patients aged 3 t...
