Abstract

OBJECTIVE:

The objective of this meta-analysis was to evaluate the efficacy and tolerance of the metabolic agent trimetazidine (TMZ), both in monotherapy and in combination with other antianginal agents, in the treatment of stable angina pectoris. A search of literature published between 1985 and 2001 was performed on computerized databases (MEDLINE and EMBASE).

METHODS:

Only double-blind, randomized, controlled trials were included in this meta-analysis. Patients had to be treated for at least 2 weeks. Four parameters were selected, one clinical parameter (number of weekly angina attacks) and three ergometric parameters (time to 1 mm ST-segment depression, total work and exercise duration at peak exercise). They were evaluated at baseline and at the end of the treatment period.The quality of the trials was assessed on specific methodological criteria. Standard statistical methods, pooled odds ratio and 95% confidence intervals for subjective symptoms and pooled z and P for objective symptoms, were used.

RESULTS:

Twelve clinical studies meeting our criteria were analyzed. Results showed that TMZ significantly reduced the number of weekly angina attacks in coronary patients and improved time to 1 mm segment depression and total work at peak exercise, while exercise duration at peak exercise showed a trend toward improvement (P = 0.09).

CONCLUSION:

This meta-analysis confirms the efficacy of TMZ in the treatment of stable angina, compared with placebo or conventional antianginal agent, as well as in monotherapy or in combination with conventional antianginal agents. TMZ is well tolerated in monotherapy as well as in combination.
