mitochondria play an important role in energy production for the cell. the proper function of a myocardial cell largely depends on the functional capacity of the mitochondria.  therefore it is necessary to establish a novel and reliable method for a non-invasive assessment of mitochondrial function and metabolism in humans. although originally designed for evaluating myocardial perfusion, 99mtc...

background: heart failure is one of the chronic heart diseases and a debilitating condition of increased prevalence in the elderly. one of the important and non‑pharmacological strategies for improving clinical outcomes in these patients is promotion of the self‑care. background and social environment in which a patient is trying to control his disease is an important factor in the self‑care. t...

background: acute renal failure describes as a syndrome by rapid decline in the ability of the kidney to eliminate waste products, regulate acid–base balance, and manage water homeostasis. when this impairment is prolonged and entered chronic phase, erythropoietin secretion by this organ is decreasing and toxic metabolic accumulates and causes hematological changes include decrease of hct, mcv ...

background: selenium (se) is an essential trace element mainly obtained from seafood, meat, and cereals. se deficiency has been identified as a major contributing factor in the pathogenesis of certain congestive heart failure (chf) syndromes. since there is controversy over the prevalence of se deficiency among patient with chf, the aim of this study was to assess the serum se concentrations in...

conclusions the hormonal levels were low in patients with idiopathic dilated cardiomyopathy. however, the prognostic significance of different hormonal deficiencies was not clear in our study populations who were receiving standard therapies for heart failure and had a relatively stable clinical condition. results except for testosterone level, the levels of gh, igf-1, t3, and t4 concentrations...

when i first met this nice lady, i was in an evening work shift of ccu. this 69 years-old woman had been referred recently to our ward. she had a pale and puffy face. she suffered from chf. she had a normal breathing, but her ankle was swollen.   we stabilized her condition easily but, it was just the first step in her treatment way. prevention of recurrence of heart attack was our goal. every ...

background: chronic kidney disease is a health problem in today’s world and hemodialysis is an alternative method for patients with chronic renal failure. preparing provincial and national information on the situation of patients can play a significant role in improving the quality of services provided to patients undergoing hemodialysis. objective: this study aimed to investigate the character...

n-terminal pro β-type natriuretic peptide (nt-probnp) is a valuable marker for monitoring the response to treatment in patients with heart failure. based on the clinically observed improvement of heart failure symptoms early after cardiac resynchronization therapy (crt), we sought to investigate whether crt induce any significant reduction in the plasma level of nt-probnp in three days after im...
