Task: Intent Identification
Input (English): Angiotensin-converting enzyme (ACE) inhibitors improve prognosis in patients with post-myocardial infarction (MI) related cardiac dysfunction. Resveratrol is a polyphenol that has been reported to be beneficial in hypertension, ischemic heart disease, and cardiotoxicity in preclinical studies. Accordingly, we investigated the comparative and combinatorial efficacy of resveratrol and perindopril (ACE inhibitor) treatment on MI-related cardiac remodeling and contractile dysfunction.', 'Left anterior descending artery-ligated and sham-operated male Sprague-Dawley rats were gavaged with vehicle, resveratrol, perindopril, and combination of resveratrol+perindopril (2.5 mg/kg bodyweight/day) for 8 weeks (starting immediately after acute MI). Echocardiography was performed to assess cardiac structure and function at baseline and 8 weeks.', 'At 8 weeks, vehicle-MI rats had a significantly lower left ventricular ejection fraction (LVEF) and increased LV dilatation compared to vehicle-sham rats. MI rats treated with resveratrol, perindopril and a combination of both had significantly improved LVEF and reduced LV dilatation. Vehicle-treated MI rats also had increased level of lipid peroxidation product- malondialdehyde (MDA), proinflammatory protein- tumor necrosis factor-alpha (TNF-α) and cardiac fibrosis marker- collagen and decreased enzymatic activity of superoxide dismutase and catalase compared to vehicle-sham rats. Resveratrol, perindopril and combination of both significantly prevented the /ed to determine systolic functional parameter increase in MDA, TNF-α and collagen and improved the activity of superoxide dismutase and catalase in MI rats compared to vehicle-MI rats.
