Long-term prognosis following exclusion of coronary artery stenosis by noninvasive coronary angiography using multislice computed tomography (MSCT) up to now has not been determined. We therefore performed noninvasive coronary angiography using MSCT (Philips Brilliance, 4 – 64 slices, retrospective ECG gating, 0.625mm collimation, 0.4sec gantry rotation time) in 1017 consecutive patients (657 male, 360 female, age 64±11years, 240 patients with known coronary artery disease (CAD)) referred to MSCT-study with chest pain. Patients with acute coronary syndromes, stents, atrial fibrillation and calcium scores > 1500 were not included. Based on MSCT results invasive study was recommended or not. All patients or the referring clinician were contacted by telephone or mail at least 6 months after their scan. Diagnostic image quality could be obtained in 992/1017 (98%) patients. In 620 of 992 patients (=63%) coronary artery stenosis could be excluded and invasive study was not recommended. Despite these recommendations invasive study was performed due to other clinical indications in 83/620 patients within < 30 days and in 43/537 patients within > 30days after the scan. Only in 13/126 patients stenoses >50% were found but no treatment was necessary. During the mean follow-up period of 612±192days 7/620 patients died but no patient suffered from cardiac death or acute myocardial infarction. In 372 of 992 patients invasive coronary angiography was recommended and performed in 230 patients (n=167 within < 30days, n=63 within >30days). In 165/230 patients stenoses >50% were found, treated by angioplasty or stents in 139/165 patients. During the mean follow-up period of 602±161days 11/372 patients died, two patients suffered from sudden, two patients from non-sudden cardiac death and one patient survived acute myocardial infarction. Thus, exclusion of coronary artery stenoses by noninvasive coronary angiography using multislice computed tomography determines a good lomg-term prognosis in patients with chest pain.

OBJECTIVES This study correlated the multi - detector computed tomography (MDCT) calcium scores with the results of coronary angiography in diabatic and/or hypertensive patients with atypical angina pectoris in order to assess its value to predict or exclude significant coronary artery disease (CAD). BACKGROUND Muti-detector computed tomography is a sensitive method to detect coronary calcium. However, it is unclear whether it may play a role as a filter before invasive procedures in patients with atypical angina pectoris. METHODS A total of 150 patients (116 men and 34 women) with diabetic and/or hypertension for at least 5 years and atypical angina pectoris from a single center were included in our study. patients underwent calcium screening with MDCT and have calcium score more than 100 , then all patient underwent invasive coronary angiography. RESULTS The Mean age was 62±5.7 and 77.3% were male, 78% of men and 88.2 % of women revealed significant coronary stenoses (> 50% lumen narrowing of left main trunk stenosis and > 70% stenosis of any epicardial coronary artery). Significant correlation between calcium scoring and significant coronary artery stenosis was seen (P: 0001). A 70% were DM, 90% were hypertensive and 61.3% were HTN and DM. The LAD artery was the most stenotic artery by 53.3% followed by RCA (37.3%) and finally LCX (30.7%). one significant coronary artery was 42% followed by two significant CAD (26.7%), while 9.3% included three-vessel disease. The significant coronary artery diseases was increased with age ( P: 0003). CONCLUSIONS Coronary calcium proved to have good diagnostic performance for significant coronary artery stenosis in patient with atypical angina pectoris.
