Performance of heart has substantial role in breaking records of sports. Achieving to optimal performance of endurance Training builds upon the consistency in several parts of body specially heart. Type, intensity, term training programs is determining components of providing structural consistency and performance of heart especially in left ventricular. Aim of this research was comparing struc...

conclusions the findings suggest that chronic coadministration of nandrolone with moderate-intensity endurance exercise facilitates the vf occurrence in rat. complementary studies are needed to elucidate the involved mechanisms of this abnormality. results nandrolone, exercise, and their combination were associated with heart hypertrophy. exercise could prevent the incremental effect of nandrol...

stress-induced cardiomyopathy or takotsubo cardiomyopathy is a recently increasing diagnosed disease manifested by transient apical or mid left ventricular dilation and dysfunction. this sign is similar to acute myocardial infarction but without significant coronary artery stenosis. there are important and essential differences between takotsubo cardiomyopathy and acute myocardial infarction in...

background: preeclampsia is a condition observed during pregnancy and threatens the life of both mother and fetus. there are studies which suggest that preeclampsia play a major role in the left ventricular mass. the aim of this study is to compare the electrocardiographic changes in normal pregnant and preeclamptic women. methods: the studied groups consisted of 48 mild preeclamptic, 33 severe...

there are many treatment modalities available to acutely terminate incessant ventricular tachycardia with variable success rates, but some cases tend to prove refractory to all of them. we report a 59-year-old woman presenting with incessant ventricular tachycardia. echocardiography revealed a large true apical aneurysm and severe left ventricular dysfunction. the arrhythmia was controlled in t...

background: longer survival after the total repair of the tetralogy of fallot increases the importance of late complications such as right ventricular dysfunction. this is a prospective study of the right ventricular function in totally corrected tetralogy of fallot patients versus healthy children. methods: thirty-two healthy children were prospectively compared with 30 totally corrected tetra...

Recognition of the natural history and responsible leading factors for regression of left ventricular hypertrophy after successful renal transplantation are very important. The aim of this study was to assess the regression of left ventricular hypertrophy after successful renal transplantation among uremic patients. In this study 27 uremic patients (18 males and 9 females) with an average a...

Abstract Objective Cardiac dysfunction is a major cause of death in patients with beta thalassemia. In these patients, repeated blood transfusion, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body and this induced heart failure. Left ventricular ejection fraction was measured in major beta thalassemia (β-Th) patients to detect the rela...

the optimal treatment method for right ventricular failure after valve surgery complicated by a low cardiac output has not been determined, although several case reports have been published on patients with ventricular failure and arrhythmia who were bridged to cardiac transplantation using biventricular or left ventricular assist devices. this case series illustrates successful circulatory sup...
