There are many myocardial and non-myocardial conditions that cause heart failure with normal left ventricular ejection fraction (LVEF). Among them, diastolic heart failure (heart failure due to diastolic dysfunction) is the most common cause of heart failure with normal LVEF. Diastolic heart failure easily can be diagnosed by comprehensive two-dimensional and Doppler echocardiography, which can...

Introduction: We aimed at evaluating the clinical, laboratory and echocardiography effects of intracoronary administration of autologous bone marrow stem cell transplantation in different clinical entities of chronic Heart Failure (HF) patients.   Methods: This procedure was carried out during an interventional study conducted in the Cardiology department from JAN 2012 to APR 2013. The HF ...

background: heart failure is a severe chronic disease and has a negative impact on the health-related quality of life (hrql). in addition to preventing disease progress, one of the important goals in heart failure treatment is to improve the patient’s quality of life. this study is aimed to compare three generic to specific quality of life instruments that are used in cardiac rehabilitation set...

Echocardiography has the ability to noninvasively explore hemodynamic variables during pharmacologic or exercise stress test in patients with heart failure. In this review, we detail some important potential applications of stress echocardiography in patients with heart failure. In patients with coronary artery disease and chronic LV dysfunction, dobutamine stress echocardiography is able to di...

rheumatic mitral valve stenosis is the most common form of organic heart disease encountered during pregnancy and continues to cause maternal and fetal mortality. medically refractory congestive heart failure due to mitral stenosis is a clinical challenge and its optimal management remains controversial. on the other hand due to hazard of x-ray to mother and fetus, there are some limitations fo...

background and objective: sleep-disordered breathing (sdb) is associated with increased morbidity and mortality in patients with heart failure (hf). we assessed the prevalence and the pattern of sdb in hf patients who were candidates for heart transplantation. materials and methods: twenty heart transplantation patients with ventricular ejection-fraction < 25% were recruited consecutively in a ...

Elevated sympathetic tone and b-AR desensitization are characteristics associated with heart failure (HF) contributors to the initiation of arrhythmia. Studies have shown that altered responsiveness in HF leads compartmentalization imparied sub-cellular cAMP signaling. Yet, if signaling is heterogeneously remodeled throughout intact heart, how this may contribute arrhythmia unknown. To assess w...

vein of galen aneurysmal malformation (vgam) is a rare congenital malformation, accounting for less than 1% of cerebrovascular abnormalities. the majority of reported cases have been associated with congestive heart failure (chf) in the neonatal period. herein, we present a case of vgam, diagnosed at 37 weeks of gestation during the intrauterine life case report: a full-term female newborn pres...

abstract         background and objective: scientific evidence reveals that the density of skeletal muscle microcirculations decreases in the patients with chronic heart failure. therefore, this study aimed to determine the impact of submaximal aerobic exercise training on restoration of fast/slow-twitch muscle fibers microcirculation in rats with myocardial infarction.          methods: in thi...
