摘要

Cardiovascular disease is one of the common causes of death worldwide, thus, there is an increasing need for discovering and identifying various measures for cardioprotection. This study evaluated the hypothesized cardioprotective effect of metformin therapy, in isoproterenol induced myocardial injury in rats. Normoglycemic Wistar rats of either sex, were divided in 4 groups (n=8) each. Two test groups were administered two different doses of metformin (100 mg/kg/day and 225 mg/kg/day respectively) orally, for 7 days prior to myocardial injury. Carvedilol (10 mg/kg/day by oraj gavage for 7 days) was administered to the positive control group. Evaluation parameters were 1. Pathological-(Histophological grading and Heart coefficient) & 2. Biochemical - (serum cardiac Troponin T and lactate dehydrogenase). The findings of our study are suggestive of cardioprotection, offered by prior short-term metformin therapy, against a subsequent myocardial insult, in normoglycemic experimental animals. This is a significant observationfor cardiovascular risk prevention in a clinical setting.
