This study aims to evaluate the effect of ECP therapy on cardiovascular hemodynamic, coronary perfusion, endothelial function, angiogenesis and artery genesis of the coronary blood vessel to refractory angina pectoris patients Refractory angina pectoris patients in Harapan Kita hospitals who do not respond to drugs adequately will be divided by 2 groups, control & treatment. Inclusion criteria include age 21 - 80 years, Refractory angina CCS III-IV whom are not candidate for Re-revascularization with proven data of: have stenosis on left main more than 50%, stenosis on main coronary right artery more than 70% or stenosis more than 70% on others vessels, conducted in coronary surgery conference with conservative decision (optimal medications). Exclusion criteria include aorta aneurysm, abdominal aneurysm, acute coronary syndrome, acute heart failure, heavy aortic regurgitation, malignant arrhythmia, blood pressure above 180/100mmHg, acute limb ischemia, DVT, active thrombophlebitis, and pregnancy. the investigator conducts a double-blind randomized control trial. The participants will get 35 hours ECP treatment, initial treatment pressure is 300 mmHg. whilst control groups will get 75mmHg. At the end of treatment, the investigator compare the hemodynamic effect on coronary perfusion, endothelial function, angiogenesis, and coronary blood vessel arteriogenesis. Quality of Life Improvement based on WHO-5 between groups
