New potential of Trimetazidine MB for coronary heart disease treatment in the real-world clinical practice: results of the Russian multi-centre randomised study PERSPECTIVE (Part II)

Aim. As a clinical part of the Russian multi-centre randomised study, to assess the clinical benefits and safety of adding Trimetazidine MB to the standard treatment scheme in patients with stable angina (SA), in order to optimise their ambulatory therapy and improve their compliance.
Material and methods. The study included 981 patients with Functional Class (FC) II-III SA and various concomitant diseases and syndromes, such as chronic heart failure (CHF), Type 2 diabetes mellitus (DM-2), or chronic obstructive pulmonary disease (COPD) in smokers. All participants were divided into two groups: Group I (n=838) received standard therapy plus trimetazidine MB (70 mg/d, twice a day), while Group II (n=143) received standard therapy only. The treatment and follow-up phases lasted for 12 months.
Results. In Group I, the weekly number of angina attacks decreased by 42 % from the baseline at one month (р<0,0001), and by 70 % at 12 months (р<0,0001). The number of nitroglycerin (NTG) tablets taken decreased, respectively, by 41 % (р<0,0001) and 68 % (р<0,0001). In Group II, the decrease in angina attack number and NTG tablet number was significant only at 6 months and was less pronounced than in Group I. Therefore, in Group I, the number of patients with FC I increased by 7 times, while the number of FC III patients decreased by 1,8 times. No marked FC dynamics was observed in Group II. In Group I, left ventricular ejection fraction (LVEF) increased by 2,4 % (р<0,001), while interventricular septum and LV posterior wall thickness decreased, respectively, by 4,2 % (р<0,01) and 3,5 % (р<0,01). These parameters, however, did not change substantially in Group II patients. At 12 months, the number of patients hospitalised due to clinical decompensation, or becoming disable, was twice as high in Group II as in Group I.
Conclusion. The Russian “PERSPECTIVE” Study results demonstrated high clinical effectiveness and safety ofTrimetazidineMB therapy, combined with standard treatment, in SA patients with CHF, DM-2, and COPD. Therefore, metabolic therapy could be more widely used in the real-world clinical settings.
