Brief summary:
This study of 402 cases of stable angina subjects who were diagnosed as Coronary Heart Disease (CHD) is a randomized, blank controlled, multi-center clinical study. Subjects who are taking standard treatment with stable symptoms will receive a 24-hour ambulatory electrocardiogram (ECG) (Holter) examination. They will be randomly divided into two groups. The nicorandil group will receive nicorandil 5 milligram (mg) (3 times a day = tid) on top of the standard treatment for 12 weeks, while the control group will stay on standard treatment. Nitrates and beta blockers need to be maintained on a stable dose. Other drugs that do not affect the primary endpoint may be adjusted per investigators decision.

Interventions: intervention 1: Nicorandil intervention 2: Standard Treatment
Intervention descriptions: intervention 1: The subjects will receive Nicorandil 5 mg tablet orally three times daily for a period of 12 weeks along with the standard treatment. intervention 2: The subjects will receive one of the standard anti-anginal therapies which included but not limited to aspirin, ACEI, lipid lowering statins and beta blockers according to the recommendation of guidelines.
