Abstract
Introduction Trimetazidine (TMZ) is an antianginal agent that acts directly at the myocardial cell level and which is now available in a once-daily (od) formulation. Methods ODA, a 3-month, observational, multicenter study in Russia, assessed the effectiveness and tolerability of TMZ 80 mg od in patients with stable angina and persisting symptoms, in real-life settings. The present analysis explored the effects of adding TMZ to background antianginal treatment with respect to the duration of stable angina. Results A total of 3032 patients were divided into four groups according to stable angina pectoris duration since diagnosis, ranging from less than 1 year to more than 10 years. A decrease in frequency of angina attacks was observed, including in patients with angina duration < 1 year, in whom the frequency of weekly angina attacks decreased from 3.8 ± 2.9 to 1.4 ± 1.7 at 1 month and 0.6 ± 1.0 at 3 months. Short-acting nitrate consumption and proportion of angina-free patients decreased, and self-reported physical activity and adherence to antianginal therapy improved in all patient groups, including recently diagnosed patients and starting already at month 1. Conclusions Addition of TMZ 80 mg od to antianginal treatment was effective in reducing the frequency of angina attacks and the use of short-acting nitrates, improving Canadian Cardiovascular Society (CCS) class, self-reported physical activity, and adherence to antianginal therapy. These beneficial effects were observed in patient groups with different durations of stable angina, suggesting an opportunity for decreasing angina burden even in recently diagnosed patients.
