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...

Heart failure in children presents important characteristic features different from adult congestive failure, from a pathophysiological and mostly from an etiopathogenic point of view. Heart failure in children is, in most cases, a consequence of congenital structural cardiac abnormalities that remained unoperated, underwent a palliative operation or presented post-surgery complications, or of ...

background chronic heart failure (chf) is associated with unpredictably increased prevalence of hospital admissions. self-care is one of the most important aspects of management for patients with chf. self-care adequacy has led to increased satisfaction, independence in daily activities, reduced stress, and morbidity. objectives we aimed to assess the relationship between self-care behavior and...

Objective(s): Exercise training is a well-known accelerator for the treatment of chronic heart failure (CHF). The current study aimed to investigate the restorative effects of aerobic interval training (AIT) intervention on myocardial energy metabolism in CHF rats. Materials and Methods: Post-myocardial infarction (MI) heart failure animal model was established. The Sprague-Dawley rats were ran...

Chronic heart failure is a major and increasing cause of morbidity and mortality. Although it is widely recognized that chronic heart failure affects the elderly, little attention has been given to its study specifically in this patient group. For example, patients with chronic heart failure in clinical trials frequently have an average age of around 60 years, in comparison to one of nearer 80 ...

the incidence and prevalence of obesity are fast increasing worldwide. various indices have been used to measure and assess obesity. the body mass index (bmi) is the most common and practical of these indices. overweight and obesity exert considerable adverse effects on the cardiovascular system. these effects are mediated through various neurohormonal and cytokine pathways, most of which are i...

heart failure (hf) is still a major problem worldwide with high morbidity and mortality rates. the recently developed medication for hf is still incapable of reducing its morbidity and mortality, and clinical data supporting the efficacy and safety of its mainstay therapy remain insufficient. arginine-vasopressin (avp) plays important roles in circulatory and water homeostasis, one of which is ...

conclusions: left ventricular systolic heart failure, may result in inter and intra-atrial asynchrony even in clinically stable patients without significant pulmonary hypertension and diastolic dysfunction. results: in heart failure patients either inter or intra-atrial asynchrony were far more common in comparison with normal subjects (p=0.008 and p=0.007 respectively). patients and methods: t...

STUDY OBJECTIVE The impact of stable, chronic heart failure on baseline pulmonary function remains controversial. Confounding influences include previous coronary artery bypass or valve surgery (CABG), history of obesity, stability of disease, and smoking history. DESIGN To control for some of the variables affecting pulmonary function in patients with chronic heart failure, we analyzed data ...
