Brief Summary:
Treatments for stable angina includes drug therapy such as calcium-channel blocker, beta blocker, and ACEI/ARB. To obtain good prognosis in patients with coronary artery disease,preventing or correcting the progression of atherosclerosis and dyslipidemia is more important than relieving angina symptom. Dysfunction of microvessel is one of the most important factor in patients with coronary artery disease. Recently, we developed the new non-invasive method of evaluating the microvessel in fundus. With this methods, we will compare the effect of each drug (beta blocker, CCB, ARB).
