[Potentialities of cytoprotection in the treatment of chronic heart failure in patients with coronary heart disease].
The study was undertaken to evaluate the effects of long-term (6-month) therapy with the selective beta-blocker bisoprolol, the cytoprotector trimetazidine and their combination on the clinical course of disease, the morphofunctional parameters of the left ventricle (LV) and life quality in 71 patients with coronary heart disease (CHD) concurrent with functional classes (FC) III-IV chronic heart failure (CHF) (ejection fraction (EF) < 35%, as evidenced by echoCG). In Groups 1, 2, and 3, basic therapy was supplemented by bisoprolol, trimetazidine, and bisoprolol plus trimetazidine, respectively. The initial dose of bisoprolol was 1.25 mg with its subsequent titration to an individually tolerable. Trimetazidine was given in a dose of 20 mg thrice daily. The patients' clinical status and echoCG were monthly assessed. There was a decrease in FC of CHD in all the groups, a reduction in LV end diastolic and systolic volumes, and an increase in shortening faction, LV EF, and an improvement of LV diastolic function. There was evidence that it should be expedient and safe to use the cytoprotector trimetazidine in the treatment of CHF in patients with CHD. In patients with CHD concurrent with CHF, therapy using a combination of bisoprolol and trimerazidine was found to have the most pronounced impact, which yielded the maximum clinical and hemodynamic effect (LV EF increased by 42.6% of the baseline values, the rate of early and late ventricular diastolic filling decreased by 59% of the baseline values). The revealed regularities of the positive effect on the clinical and hemodynamic parameters of long-use of bisoprolol, trimetazidine, and their combination in patients with CHD concurrent with FC III-IV CHF show it expedient to include these drugs and their combination into therapy for CHF that develops in the presence of CHD.
