Efficacy of trimetazidine – an inhibitor of free fatty acids oxidation in the treatment of patients with stable angina pectoris and heart failure

https://doi.org/10.18087/cardio.2021.11.n1801

Abstract

Aim      To evaluate efficacy of modified-release trimetazidine (TMZ) included into the standard therapy for patients with stable angina and chronic heart failure (CHF) as a part of a subgroup analysis in the PERSPECTIVE study.

Material and methods  The study included 806 patients: group 1 (n=691), patients receiving a standard therapy and modified-release TMZ (TMZ group); and group 2 (n=115), patients receiving a standard therapy (control group). Total duration of the study was 12 months.

Results In the TMZ group, the weekly number of angina attacks decreased by 41.9% (p<0.0001) in 2 months and by 69.6 % (from baseline, р<0.0001) in 12 months, and the frequency of nitroglycerine dosing decreased by 40.8 % (р<0.0001) and 67.7 % (р<0.0001), respectively. In the control group, the respective values did not change. In the TMZ group compared to the control group, the QT interval was shorter (7.9 %; р<0.05), the left ventricular (LV) end-systolic dimension was reduced (13.4 %; р<0.01), interventricular septal thickness and LV posterior wall thickness were decreased (9.5 %; р<0.01 and 12.2 %; р<0.01, respectively), and the ejection fraction was increased (11.4; р<0.05). Following the TMZ treatment, the leukocyte count in peripheral blood was decreased (5.3 %; р<0.01) and the serum concentration of high-sensitivity C-reactive protein was decreased (30.7 %; р<0.01) vs. increases of these indexes in the control group (17.9 %; р<0.05 and 17.8 %; р<0.05, respectively). The proportion of patients hospitalized for exacerbation of CHF or angina for 12 months was 8.6 % in the TMZ group and 15.7 % in the control group (p=0,001).

Conclusion      In patients with stable angina and CHF, inclusion of modified-release TMZ into the standard therapy decreases the number of angina attacks, reduces the activity of inflammatory factors, and improves the course of disease.
