Therapeutic effect of trimetazidine on elderly patients with refractory angina pectoris

Objective To evaluate the effect of trimetazidine on elderly patients with refractory angina pectoris on the basis of intensive treatment. Methods Sixty - five patients with refractory angina pectoris were randomized into intensive treatment group and TMZ treatment group. In TMZ treatment group,TMZ(20 mg, 3 times per day) were given in addition to intensive treatment. The cycles of treatments in both groups were 4 weeks. The frequency and duration of angina attack, the ST - T segment change of electrocardiogram and the dosage of drugs belonging to ester nifrate were observed in patients with refractory angina pectoris. Results The total effective rate was 88.57% in TMZ group,and there was significant difference between the two groups ( P ＜ 0. 05 ). With regard to the frequency and duration of angina attack,the dosage of drugs belonging to ester nitrate, the maximal ST - T segment depression, there were also significant differences between the two groups ( P ＜0. 05). Conclusions Combinating therapy of TMZ with intensive drugs have good curative effect for refractory angina pectoris, and is safe and reliable.
