[Observation on effect of compound danshen droplet-pill combined with trimetazidine in treating senile unstable angina pectoris].

OBJECTIVE

To investigate the effect of compound Danshen Droplet-pill (DS) combined with trimetazidine (TMZ) in treating senile unstable angina pectoris (SUAP).

METHODS

One hundred and twenty patients with SUAP were eaually and randomly divided into 2 groups, the treated group and the control group. Changes of angina, occurrence of arrhythmia, myocardial infarction and sudden death, myocardial ischemia in ECG and partial indexes of heart function were observed.

RESULTS

The total effective rate in the treated group was 78.3%, while that in the control group was 53.3%, comparison of the two groups showed significant difference (P < 0.05). The incidence rate of arrhythmia in the two groups was 18.2% and 30.0% respectively and that of acute myocardial infarction and sudden death was 0 and 5.0% respectively, also showed significant difference between them (P < 0.05). Condition of myocardial ischemia revealed in ECG and partial indexes of heart function in the treated group were all improved to certain extent. Conclusion DS combined with TMZ is superior in treating SUAP.
