Trimetazidine in geriatric patients with stable angina pectoris: the tiger study

This study aims to assess the efficacy and tolerance of the metabolic antianginal agent trimetazidine, a 3-KAT inhibitor, in 141 stable angina patients aged 65-86 years. Efficacy was assessed with exercise tests and clinical evaluation after 12 weeks of treatment. The main outcome was an increase in exercise duration by 52 +/- 92 sec (p < 0.001). Other exercise test parameters also improved, with no change in rate-pressure product. Angina attacks and short-acting nitrate consumption significantly decreased, indicating an improvement in quality of life. Two adverse events were reported (gastric pain and dyspepsia) but they were mild and transient. In conclusion, in elderly stable angina patients, trimetazidine improves exercise stress tests and angina symptoms. Because of its metabolic effect, free from any haemodynamic action, trimetazidine proved to be beneficial in elderly patients and with an excellent tolerance profile.
