The study investigates the cardioprotective effects of 7-hydroxy frullanolide (7-HF) on myocardial infarction induced by isoproterenol in rats. The findings suggest that 7-HF significantly reduces myocardial injury by decreasing infarct size, preserving myocardial tissue histology, and reducing cardiac biomarkers. It also increases the expression of the cardioprotective gene Nrf2 and reduces the expression of iNOS. Additionally, 7-HF improves cardiac function by decreasing cardiac workload and reducing peripheral vascular resistance. The study concludes that 7-HF has potential as a cardioprotective agent, which may be due to its modulation of iNOS and Nrf2 genes and improvement of cardiac functions.

The study investigates the cardioprotective effects of the antioxidant flavonoid diosmetin in a rat model of myocardial infarction induced by beta 1-adrenergic receptor activation. Diosmetin was found to attenuate the effects of isoproterenol-induced myocardial infarction, as evidenced by improvements in electrocardiography, cardiac biomarkers, and histopathological analysis. The results suggest that diosmetin may offer therapeutic benefits for myocardial infarction by reducing oxidative stress and myocardial damage.
