background: myocardial infarction is the main cause of death worldwide. angiogenesis, a promising new therapy for the treatment of diffuse coronary artery disease, shows a poor response to conventional revascularization techniques. this study focused on improving myocardial function using endothelial cells (ecs) and mesenchymal stem cells (mscs) in a sheep animal model. methods: acute myocardia...

introduction: the aim of the present study was to evaluate the effect of exercise training and l-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (mi). methods: four weeks after the surgically-induced mi, 40 male wistar rats were randomly assigned to the following 4 groups (n=10): mi-sedentary control (sed) mi-exercise (ex) mi-sed...

introduction: although left ventricular(lv) function parameters measured by gated myocardial perfusion spect (gspect) have been validated, experimental data have revealed that the calculated the lv function parameters using gspect are affected by patient populations as well as particular acquisition and processing conditions. we tried to determine the normal values of gspect in an iranian popul...
