OBJECTIVE The clinical use of doxorubicin, which is a strong antineoplastic agent, is limited due to its cardiotoxic side effects. Metformin is a drug with antihyperglycemic effects, and it has been shown to have a cardioprotective effect on left ventricular function in experimental animal models of myocardial ischemia. The present study investigated the cardioprotective effect of metformin in ...

The present study investigates the cardioprotective effect and antioxidant activity of a chronic treatment of Ginkgo biloba Phytosomes (GBP) in isoproterenol (ISO) induced cardiac necrosis in rats. Pretreatment of GBP 100 mg/kg daily for 30 & 45 days to rats treated with ISO (85 mg/kg, s.c) on the last 2 days, resulted in a significant cardioprotective activity reflected by attenuation of the I...

Hyperpolarization-activated cyclic nucleotide–gated (HCN) channels, primarily their HCN4 subtype, are one of the promising targets for development cardioprotective agents. HCN channel blockers have a selective bradycardic effect, preserving myocardial contractility and diastolic function not affecting electrophysiological parameters heart. This review continues series reviews on analysis compou...

Exercise increases serum opioid levels and improves cardiovascular health. Here we tested the hypothesis that opioids contribute to the acute cardioprotective effects of exercise using a rat model of exercise-induced cardioprotection. For the standard protocol, rats were randomized to 4 days of treadmill training and 1 day of vigorous exercise (day 5), or to a sham exercise control group. On da...

Previously, we demonstrated (17) that 11,12- and 14,15-epoxyeicosatrienoic acids (EETs) produce marked reductions in myocardial infarct size. Although it is assumed that this cardioprotective effect of the EETs is due to a specific interaction with a membrane-bound receptor, no evidence has indicated that novel EET antagonists selectively block the EET actions in dogs. Our goals were to investi...
