Introduction: Coronary heart disease is the most common cause of myocardial ischemia. The present study was aimed to evaluate the effect of resveratrol and aerobic exercise together and singularly on some cardiovascular risk factors in rat model of acute heart failure due to isoproterenol application.
Materials and Methods: In this experimental study, 46 male Wistar rats were divided into five groups randomly as follows: the healthy control (CON), isoproterenol induced myocardial infarction without implementation (ISO), resveratrol treated rats (ISO+RES), exercise treated rats (ISO+EXE) and combination of resveratrol and exercise groups (ISO+RES+EXE). Rats in the resveratrol groups received daily dose of 25 mg/kg/bw of resveratrol and exercise groups ran 1 h/d and 8 weeks on treadmill. Subsequently, all animals received subcutaneous isoproterenol on two consecutive days at the end of experiment. Then, animals anesthetized and blood samples were collected for analysis.
Results: The results showed that pretreatment with a combination of resveratrol and aerobic exercise led to a significant reduction in troponin-I in the animals. Also, exercise training, resveratrol and combinations of them were prevented the increasing CRP indices, but there was not significant effect in these groups (P> 0.05). Pretreatment with exercise training as well as combination of resveratrol and exercise training caused a significant decrease serum cholesterol and triglyceride levels were compared to the isoproterenol group (P≤ 0.001). Pretreatment with resveratrol, exercise training and a combination of both significantly increased in HDL-C and pretreatment only in mixed group led to significant decrease in LDL-C compared to the isoproterenol group (P= 0.001).
Conclusion: Regular exercise and resveratrol supplementation is likely to be effective on cardiovascular risk factors and the combination of the two variables in the prevention of inflammation and will have a significant role in heart damage caused by myocardial infarction
