Objective:To evaluate the efficacy of coronary stenting in the treatment of patients with unstable angina.Methods:38 patients with unstable angina underwent coronary stenting based on routine conservative therapy.The clinical outcome was evaluated with regard to the frequency of angina and the changes in electrocardiogram.The patients were followed up for average 6 months.Results:The procedural success rate was 94.7% in the patients with residual stenosis less than 10% and initial TIMI grade 3 flow.There were no recurrent angina in 36 patients and significantly less angina frequency in 2 patients.The electrocardiogram in 29 patients recovered normally.More than 50% ST-T segment changes happened in 5 patients while 4 patients suffered no obvious changes.During the follow-up

4 patients presented recurrent angina

3 of which underwent repeat coronary stenting.There was no acute myocardial infarction or death.Conclusion:Coronary stenting is a safe and effective treatment for unstable angina.
