“…The LCX had 12 plaques (17.1 %), the RCA had 15 plaques (21.4 %) and the small branches had 14 plaques. This is close to Madhok et al, (26) who detected 187 plaques affecting all coronary arteries, 60 plaques (32.1 %) were detected in the LAD, 40 plaques (21.4 %) were affecting the LCX, 44 plaques (23.5 %) were seen in the RCA and 29 plaques (15.5 %) were detected in the small branches. This slightly differs from Niazi et al, (17) who detected 60 plaques affecting all coronary arteries, 24 plaques (40 %) were detected in the LAD, nine plaques (15 %) were affecting the LCX, 18 plaques (30 %) were seen in the RCA and seven plaques (11.6 %) were detected in the small branches.…”

“…The significant plaques in our study were 29, the most commonly affected vessel was LAD showing 10 plaques (34.5 %), five plaques (17.2%) were detected in the LCX, seven plaques (24.1 %) were detected in the RCA and seven plaques (24.1 %) seen within the small branches. This is close to Madhok et al, (26) who detected 96 significant plaques, 43 of them (44.7 %) were affecting the LAD, 17 plaques (17.7 %) were affecting the LCX, 19 plaques (19.8 %) were affecting the RCA and 14 plaques (14.6 %) were seen within the small branches. According to the number of affected vessels, we found 15 patient having single vessel affection only six (40 %) of them had significant CAD.…”

“…Among these 70 detected plaques, 29 of them (41.4 %) were significant and 41 plaques (58.6 %) were non-significant, This is close to Chu et al, (18) who detected 480 plaques, 238 of them (49.6 %) were significant and 242 plaques (50.4 %) were non-significant. This differs from Madhok et al, (26) who detected 187 plaques, 96 of them (51.3 %) were significant and 88 plaques (48.7 %) were non-significant.

We sought to evaluate the role of non-invasive Multidetector computed tomography angiography (CTA) in the assessment of the causes of unstable angina. Background: Detection of coronary artery disease (CAD) using invasive coronary angiography needs extended time, contrast load, and high radiation exposure. Methods: 160 slices CTA was performed in 50 patients (38 men, mean age 55.48 ± 10.88years) symptomatic patients diagnosed as unstable angina. In this study, the mean coronary artery calcium score (CACS) was 204. Statistically higher CAC was found in patients ≥ 60 years old than those < 60 years. Female patients, hypertensives and diabetic patients show slightly higher (but not significant) level of CAC. Among 50 patients complaining of unstable angina we found 11 patients having normal CTA, four having dense coronary calcification, 21 having non-significant obstructive lesions, and 14 patients having significant CAD. We found significant relation between calcium score and the significance of CAD. We detected 70 plaques (29 of them caused significant stenosis) distributed in all coronary arteries. The most commonly affected artery was the LAD, followed by LCX then RCA and the small branches had only 14 plaques. According to the type of plaques, 45 plaques were mixed, five plaques were calcified and the last 20 were soft plaques. We found no significant difference in the significance of stenosis was detected in relation to the number of vessels affected. Patients were classified into Low, Intermediate, and High probability of CAD. We found significant relation between the pre-test probability and the significance of CAD. Conclusions: Multi-detector CTA allows accurate non-invasive assessment of patients presented with unstable angina.

“…The prevalence of males with CAD was nearly 1.5 times higher than that of females (62.6%) ( Table 1 ), similar to the study by Sato et al. 18 Males accounted for 85% of the study population, similar to Madhok 19 (90% males). The mean age was 66.31 ± 9.65 years, similar to De Graaf 20 (65 ± 13 years) and Sato et al.…”

Background: Coronary artery disease (CAD) morbidity and mortality increasing day by day in India as well as worldwide. Coronary arteries visualization by using invasive catheterization angiography is still using as a front-line diagnostic tool to evaluate the patients with CAD. 128 slice dual source CT improves the cardiac imaging such as high scanning speed, good temporal resolution and low radiation dose. Objective: To assess the diagnostic accuracy of 128-slice dual source CT cardiac angiography with conventional catheter angiography to find common arteries involved in CAD. Methods: This is a prospective, comparative, cross sectional study conducted at cardiology OPD. Patients with complaint of chest pain and suspected CAD were evaluated by CT and conventional coronary angiography and results were compared. Serum creatinine and ECG status were analyzed before the angiography. SIEMENS 128-slice Dual Source Flash Definition CT Scanner was used as a CT coronary angiography. Severity distribution of coronary artery disease, artery wise distribution of non-significant, significant lesions and coronary artery dominance pattern were analyzed and compared. Results: A total of 70 suspected CAD patients were selected and analyzed. American Heart Association (AHA) model of 17-segment was used to assess the coronary arteries. Normal angiograms reported in 15.71% patients and 58.57% had significant disease. A total of 356 lesions were identified from 690 out of 720 segments. Right coronary artery (RCA) is the most common location of significant lesions which contributes 33.5% (n=55/164). Coronary circulation of right-sided dominance was most commonly reported (70.0%). CT angiography showed 96.13% of an overall sensitivity, 96.28% specificity, 89.72% positive predictive value and 98.49% negative predictive value. Conclusion: 128-slice dual source CT scanner has showed high accuracy and act as non-invasive assessment of coronary arteries in patients with CAD Keywords: Cardiac angiography, Catheter coronary angiography, CT coronary angiography, 128-slice MDCT, Conventional angiography
