| Abstract | ||
| ackground: The presence of calcification in the epicardial coronary arteries indicates that the patient has coronary atherosclerosis, CT scan is a reliable noninvasive investigation to detect the degree of coronary calcification. Aim: to study correlation between the degree of coronary calcification and severity of coronary artery stenosis by CT-angiography Patient and method: one hundred and seventy-five patient ,119(68%) are male and56 (32%) are females. mean age is 55.52for males &55.30 for females, who was referred to the Iraqi Medical center in Karbala for CCTA between october2009- Nov.2013. They have either clinical diagnosis of CAD or chest pain suggestive of CAD. They were studied using CT-64 slices, initially by smart score to assess their calcium level using Agatston score, then contrast given to complete the examination, all coronary arteries were studied for any stenosis. The result was analyzed using SPSS 19. Results & Discussion: There is statistically significant positive correlation (P value less than 0.005) between the degree of CAC score and the degree of vascular obstruction, also with the number of diseased vessel. It also revealed that 12.9%. of symptomatic patients with negative calcium score may have obstructive lesion although of fewer vessel & of mild obstructive lesion Conclusion: in symptomatic patient CAC score reflect the severity of CAD especially if it is of high degree but in the absence of calcification it does not exclude presence of diseased vessel.
