  Purpose

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).

Primary Outcome Measures:
  • Wall to lumen ratio of fundus vessel [ Time Frame: baseline, 9 months ] [ Designated as safety issue: No ]
    Measurement of change in the ratio of wall thickness to lumen of the fundus vessel from baseline to 9 month follow up


Secondary Outcome Measures:
  • lipid parameter [ Time Frame: baseline, 9 months ] [ Designated as safety issue: No ]
    Measurement of change in total cholesterol, triglyceride, LDL, small dense LDL, and HDL

  • Serum markers of inflammation [ Time Frame: baseline, 9 months ] [ Designated as safety issue: No ]
    CRP

  • Change of nitrate need [ Time Frame: baseline, 1 months, and 3 months ] [ Designated as safety issue: No ]
    Measure of change of nitrate need
