We surveyed 586 patients who had been examined CCTA. Out of those patients, 299 (52%) has stenosis of coronary arteries; 166 males (28%) and 133 females (23%). Among them 246 stenosis patients (82.6%) are in 50’s to 70’s. The number of patients with 50% or more stenosis in more than 1 coronary artery is 299 including 43 males (33.9%) in their 60’s and 39 females (37.5%) in their 70’s. When a vessel score is higher than 2 points, 70 patients (50.1%) among 139 have 70% or more stenosis; 32 males (39.5%) in their 60’s and 27 females (46.6%) in their 70’s. It is noted that 14 patients in their 70’s show more cases compared to other ages up to 2 or even 5 times when a vessel score is 3 points. LAD shows 77.6% of stenosis, LCX 47.5% and RCA 60.5%. Frequency of a triple vessel disease is high for patients in their 70’s; 15 males (36.6%) and 13 females (56.5%) for both. 196 people (33.4%) in the group with stenosis have calcification, while only 40 (6.8%) in the group without stenosis have it. It means that calcification has a significant, if not absolute, correlation with stenosis of coronary arteries.
