Anti-ischemic efficacy of combination of trimetazidine with enalapril in patients with stable effort angina and metabolic syndrome

Efficacy of combination of trimetazidine (60 mg/day) and enalapril in patients with stable effort angina and metabolic syndrome was assessed in a randomized placebo controlled study of 64 patients. Anti-ischemic activity of trimetazidine was found to be significant. It was most pronounced in patients with abnormal 24-hour blood pressure index, waist/hip circumference ratio >1.0 at the background of satisfactory clinical and laboratory compensation of type 2 diabetes.     

Clinical efficacy of combined therapy with enalapril + trimetazidine in patients with hypertension comorbid with ischemic heart disease and metabolic disturbances

AIM: To compare hypotensive and antiischemic efficacy of enalapril combination with trimetazidine or placebo, effects on plasmic lipid spectrum and membrane-cell parameters of erythrocytes and platelets in hypertensive patients with ischemic heart disease (IHD) in the presence of metabolic disturbances. MATERIAL AND METHODS: A randomized placebo-controlled comparative trial included 64 patients (mean age 55.60 +/- 0.52 years) with hypertension stage I-III, IHD (stable effort angina FC II-III, obesity of the first-third degree, diabetes mellitus type 2. The patients were divided into two groups matched by gender, age, duration of the disease, office blood pressure (OBP), functional class (FC) of effort angina, body mass index, glucose levels in the blood. 43 patients of group 1 received enalapril and trimetazidine. 21 patients of group 2 were treated with enalapril and placebo. The efficacy of the treatment was assessed by changes in the 24-h profile of BP and ECG, blood lipid spectrum and membrane-cell parameters. RESULTS: A significant fall was seen in systolic blood pressure of both groups patients. In group 1 there was an additional lowering of temporal index of systolic pressure, nocturnal diastolic, mean 24-h diastolic, mean 24-h blood pressure, double product of ischemic episodes, total cholesterol, dienic conjugates in platelets. Catalase activity in erythrocytes rose. CONCLUSION: An antiischemic effect of the therapy in stabilization of blood pressure, normalization of plasmic lipids and lipoperoxidase in erythrocytic and platelet membranes under multidirectional correlations between clinical and biochemical parameters point to different mechanisms of ischemic correction in enalapril and trimetazidine.
