Efficacy of trimetazidine on functional capacity in symptomatic patients with stable exertional angina--the VASCO-angina study.

Abstract

BACKGROUND/OBJECTIVES:

Trimetazidine (TMZ) is a metabolic agent of proven efficacy in improving myocardial ischemia and angina. VASCO, a randomised double-blinded, placebo-controlled trial, assessed anti-anginal efficacy and safety of standard and high dose of modified-release TMZ (70 mg/d and 140 mg/d) in symptomatic and asymptomatic patients with chronic ischemic heart disease receiving background atenolol 50mg/d on exercise test parameters. The VASCO-angina study assessed the efficacy of the two doses of TMZ on total exercise duration (TED) and time to 1-mm ST segment depression (T1), in symptomatic patients with chronic stable angina receiving background atenolol treatment.

METHODS AND RESULTS:

In the all cohort of chronic stable angina patients TMZ significantly improved TED compared to baseline and to placebo. Both doses of TMZ significantly increased TED (p=0.0044 and p=0.0338 for TMZ 140 mg/d and TMZ 70 mg/d, respectively). A greater TED improvement was observed in TMZ 140 mg/d than in TMZ 70 mg/d, although the difference was not significant. Amongst patients with limiting angina during exercise test, both doses of TMZ significantly improved both T1 and TED. No difference in serious adverse events was noted between TMZ and placebo.

CONCLUSIONS:

The VASCO-angina gives evidence for the efficacy and tolerability of standard and high dose of TMZ in improving effort-induced myocardial ischemia and functional capacity in patients with chronic stable angina receiving background beta-blockers.
