Aim: This study of trimetasidine effects on plasmic hemostasis and blood biochemistry in patients with chronic heart failure (CCF) of NYHA functional class II-III.
Materials and methods: This study enrolled 30 patients (24 males and 6 females) aged 40-72 years with class II-III CCF, postinfarction cardiosclerosis and ejection fraction under 40%. Previously the patients received perindopril (the inhibitor of angiotensin converting enzyme) in daily dose 2-4 mg, on-demand digoxin and diuretics. Trimetasidine was given in a daily dose 60 mg for 6 months. Before and after the treatment the patients' blood was examined for: levels of factors VII and X of antithrombin III coagulation, soluble fibrinomonomeric complexes (SFMC), fibrinogen, glucose, uric acid, creatinines, total cholesterol, high density lipoprotein, triglycerides, AST, ALT, LDH, acid phosphotase, gamma-GT, sodium, potassium, activated partial thrombin time.
Results: Initially, the patients had a 23.9% increase in the levels of factors VII and X, a 14.3% decrease of antithrombin III, 29.8 and 227.6% rise in concentrations of fibrinogen and SFMC, respectively, compared to controls. Aftertreatment values of fibrinogen, factors VII and X, SFMC fell by 21.1, 17 and 35.5%, respectively. The thrombin time arose by 17.9% (p > 0.05). Insignificant inhibition was registered in the activity of acid phosphotase and gamma-GT. Glucose, AST, ALT, LDH levels remained unchanged. Plasma creatinine tended to lowering. Total cholesterol insignificantly increased at high levels of HDL cholesterol (p > 0.05) and reduced levels of triglycerides (p > 0.05).
Conclusions: Trimetasidine therapy, given after conventional treatment with diuretics, digoxin, inhibitor of angiotensin-converting enzyme, aspirin has a beneficial effect in patients with circulatory deficiency through improving hemostatic and biochemical parameters.
