    Journal: Ter Arkh; 2006; 78(9):38-43. PubMed ID: 17076223.
    Abstract:
    AIM: To examine effects of trimetasidine on morphofunctional indices of the left ventricle (LV) in myocardial infarction (MI) patients on combined treatment. MATERIALS AND METHODS: Seventy five patients with primary macrofocal MI were randomized into 2 groups. Patients of group 1 (n = 38) received a combination of bisoprolol (beta-blocker) with enalapril (ACE inhibitor) in individual doses under control of blood pressure and blood creatinine level. Group 2 (n = 37) patients received the same combination of drugs and, in addition, trimetasidine in a dose 70 mg/day from postmyocardial day 7-10 for 6 months. Two subgroups from the groups were given systemic thrombolytic therapy (STLT) with streptokinase. MRT and cine-MRT of the heart were made for measurement of LV morphofunctional parameters. RESULTS: Low-field MRT of the heart in MI patients treated with adjuvant STLT (1500000 U within 6 hours after MI onset) and trimetasidine (preductal MB) in a dose 70 mg/day from the disease day 7-10 registered a significant inhibition of pathological LV postinfarction remodeling: a decrease of body surface indexed LV end diastolic volume by 10.3%, systolic volume--by 15.4%, LV myocardial tension--by 14.0%, sphericity index--by 7.1%; an increase in the index of relative wall thickness by 5.3%, cardiac index--by 9.2% compared to the group treated without trimetasidine. CONCLUSION: 6-month therapy with trimetasidine of MI patients leads to a significant regress of morphofunctional changes accompanying LV remodeling. Pathological LV postinfarction remodeling inhibits significantly in MI patients combined treatment of whom included STLT (streptokinase in a dose 1500,000 U within 6 hours after acute MI onset and trimetasidine in a dose 70 mg/day on postmyocardial infarction day 7-10).
