Objective of the the study was to research the role of FRS in assessing CAD risk in patients with type 2 Diabetes who have been indicated coronary angiography (CA). The results indicated that the higher CAD risk patients have, the more damaged their coronary arteries are, specifically, 3 - branch damage, severe arteriostenosis: 100 percent and 44.5 percent in high risk group, 74.2 percent and 26.9 percent in low risk group respectively. In male, when initial risk cut-off is 10 percent, CAD is predicted with 73.7 percent sensitivity, 80 percent specificity, 80 percent accuracy (p = 0.005). In female, when initial risk cut-off is 5 percent, CAD is predicted with 51.6 percent sensitivity, 100 percent specificity, 77.4 percent accuracy (p = 0.049). In conclusion, FRS plays an specific role in classifying CAD risk in the group of patients with type 2 Diabetes.
