background: serum trace element alteration has been reported in dilated and ischemic cardiomyopathy. the reports were controversial. we have studied serum zinc level in cardiomyopathy patients in northern province of mazandaran and compared them with healthy volunteers. methods: serum zinc level was measured in 30 ischemic and 18 dilated cardiomyopathy patients against 27 healthy volunteers. it...

introduction: differentiating between ischemic cardiomyopathy (icm) and idiopathic dilated cardiomyopathy (idcm) is important as coronary revascularization can improve prognosis in the ischemic subgroup. due to inherent problems of coronary angiography in patients with depressed ejection fraction (ef) introducing a noninvasive tool to diagnose those who will benefit from angiography seems to be...

conclusions lv twist, torsion and untwist and also rate of them are significantly impaired in dcm and this impairment is well-related to lv global systolic and diastolic dysfunction. vvi is a new noninvasive technique that can be used to evaluate lv torsional parameters. results lv twist value (5.54 ± 1.94° in dcm vs. 11.5 ± 2.45° in control group) and also lv torsion (0.71 ± 0.28°/cm in dcm vs...

background: cardiac resynchronization therapy (crt) is an effective treatment for patients with moderate to severe heart failure. however, 20-30% of patients remain non-responders to crt. we sought to identify which patients benefit the most from crt in regard to the etiology of heart failure. methods: eighty-three consecutive patients (62 men) who had a biventricular pacemaker inserted at tehr...

background differentiating ischemic from nonischemic cardiomyopathy is important both prognostically and therapeutically, although it may be difficult clinically. objectives we aimed to determine the diagnostic power of cardiogoniometry (cgm) in the differentiation of the ischemic from the nonischemic etiology of left bundle branch block (lbbb). patients and methods we studied 37 patients with ...

background: differences in the quantity and distribution of coronary veins between patients with ischemic and non-ischemic cardiomyopathy might affect the potential for the left ventricular (lv) lead targeting in patients undergoing cardiac resynchronization therapy (crt). in the current study, we assessed and compared the suitability of the coronary venous system for the lv lead placement in i...

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...

OBJECTIVES: To investigate the association between diastolic function and the different beneficial effects of cardiac resynchronization therapy in patients with heart failure due to different causes. METHODS: The 104 enrolled patients were divided into an ischemic cardiomyopathy group (n=27) and a non-ischemic cardiomyopathy group (n=77) according to the cause of heart failure. Before implant...

INTRODUCTION The aim of the study was to investigate at long-term follow-up the incidence of appropriate implantable cardioverter-defibrillator (ICD) shocks and of all-cause mortality in patients with ICDs with ischemic cardiomyopathy versus nonischemic cardiomyopathy. MATERIAL AND METHODS ICDs were implanted in 485 patients with ischemic cardiomyopathy and in 299 patients with nonischemic ca...
