OBJECTIVE: To evaluate the effects of cilostazol on long-term clinical outcomes in patients underwent coronary stent implantation. METHODS: One hundred patients who underwent coronary stenting were randomly assigned to receive cilostazol 200 mg/d for 6 months (n = 50) or ticlopidine 500 mg/d for 1 month (n = 50). Aspirin 100 mg/d was administrated concomitantly with cilostazol or ticlopidine. Angiographic follow-up was carried out at 6 months and clinical follow-up for 3 years after stenting. RESULTS: Angiographic restenosis occurred in 5 of 34 patients (14.7%) in cilostazol group and 10 of 37 patients (27.0%) in ticlopidine group (P = 0.204). At the end of three-year follow-up, the incidence of major adverse cardiac and cerebral events (MACCE) was greatly reduced in cilostazol group compared with ticlopidine group (16% vs 36%, P = 0.023). Changes of Seattle angina questionnaire (SAQ) physical limitation score showed no significant difference between two groups (21.8 +/- 12.3 vs 16.8 +/- 15.9, P = 0.086). However, changes the improvement of angina frequency score much more was significant in cilostazol group (22.6 +/- 12.7) compared with that in ticlopidine group (16.1 +/- 13.3, P = 0.015). Recurrent angina occurred in 38% of patients in cilostazol group and 54% in ticlopidine group, respectively (P = 0.105). Readmission due to cardiac and cerebral vascular diseases was much less in cilostazol group than that in ticlopidine group (20% vs 40%, P = 0.029). CONCLUSIONS: Cilostazol treatment significantly reduced MACCE and improved the quality of life pf patients in three-year clinical follow-up after coronary stenting.
