A Multi-centric Study to Assess the Efficacy of Sigmart in Subjects With Recurrent Angina After Coronary Revascularization
A Clinical Trial to Assess the Efficacy of Sigmart in Patients With Recurrent Angina After Coronary Revascularization
The multi-centric, open label, single arm and self controlled study is planned to assess the efficacy of orally administered Sigmart in subjects with recurrent angina after coronary revascularization. The primary objective of this study is to demonstrate that orally administered Sigmart can improve the major Exercise Tolerance Test (ETT) result in recurrent angina subjects.

Drug: Sigmart (nicorandil)
Sigmart will be administered for 2 weeks when the subject enters the secondary treatment period (Day 15 to approximately Day 28), at the dosage of 5 mg per oral tid in addition to the previous anti-anginal regimen.
