OBJECTIVES: To determine correlation of zero coronary artery calcium score (CACS) with non-significant coronary artery stenosis by using computed tomography coronary angiography (CTCA). METHODOLOGY: 62 patients with suspected coronary artery disease (CAD) underwent CACS test and CTCA from April 2018 to November 2020. Patients were examined with 160 slice multidetector CT and grouped according to their age, gender, CACS, and maximum coronary luminal stenosis. CACS was assessed using Agatston scoring and degree of stenosis was assessed by automatic software and severity was scored according to CAD-RADS. The correlation between these two main variables was calculated using Spearman rank correlation. RESULTS: The 62 patients were divided into four groups according to CACS, using the Agatston Unit (AU). Group 1; 0 AU (41 patients, 66.13%), Group 2; 1-100 AU (13 patients, 20.97%) Group 3; 101-400 AU (4 patients, 6.45%), Group 4; 401-1000 AU (4 patients, 6.45%). In 41 patients with zero calcium score (32 males and 9 females), 38 patients (92.68%) were found to have no coronary artery stenosis, 2 patients (4.87%) had mild coronary artery stenosis and 1 patient (2.43%) had moderate coronary artery stenosis. Total 35 patients presented for screening purpose out of which 25 (71%) had zero calcium score and no significant coronary artery disease. CONCLUSION: In high risk patients, zero calcium score excludes significant coronary artery stenosis (50%), hence coronary calcium score is a good screening tool before subjecting patients to coronary angiography.

Introduction: MDCT coronary angiography has been evolving as a noninvasive method for the assessment of coronary artery disease (CAD). More recently, It has been demonstrated that MDCT identifies reduced contrast enhancement in ischemic and/or scarred myocardial segments. Objective: to determine the ability of rest-stress multidetector computed tomography (RS-MDCT) to detect myocardial ischemia and to assess the relationship between MDCT myocardial perfusion abnormalities and coronary artery stenosis. Methods: Forty seven patients underwent stress/rest 99mTc sestamibi SPECT and RS-MDCT, using a 16-row detector scanner (Philips Brilliance-16). Myocardial segments were classified by SPECT as normal, ischemic or scarred. SPECT results were then compared with MDCT regional myocardial contrast enhancement. The results of MDCT coronary angiography were also analyzed in 20 patients who underwent invasive catheterization. Results: The presence of a reduction in contrast enhancement at rest by MDCT identified scar by SPECT with 96% sensitivity and 98% specificity. A stress-induced reduction in contrast enhancement by MDCT identified ischemia by SPECT with 77% sensitivity and 99% specificity. The segment-based sensitivity and specificity for the detection of significant stenosis by MDCT were 92% and 98%, respectively. Conclusion: Our results showed that a rest-dipyridamole stress MDCT protocol can identify the presence of myocardial ischemia as well as the severity of coronary artery stenosis in patients with suspected coronary artery disease.

Abstract Coronary artery calcium score (CAC) measures the calcium contained in the artery wall and it is evaluated using multi-slice cardiac CT and CAC represents a useful tool for appreciating the burden of coronary atherosclerosis and for determining the risk for cardiovascular events. The purpose of this study is that CAC can be use for guiding treatment strategy in patients classified as high risk based on Framingham score . We prospectively enrolled 64 pts (79% male), 62,7+/-5 year, between 2002-2017. All included patients were considered high risk based on EuroSCORE model. A multislice heart CT scan was performed for every patient with CAC score determination quantified with the Agatston score and expressed as Agatston Units (AU). The patients were divided in 3 groups according to the treatment that they received during the 5 years follow up: optimal medical treatment for coronary artery disease (OMT) – 35.9% (23), percutaneous coronary angioplasty (PCA) – 29.7% (19) and coronary artery bypass graft (CABG) – 34.4%. The CAC score for pts treated by OMT vs CABG +/_ PCA were compared using the ROC curves. CAC score was statistically significantly superior in CABG+ PCA patients versus OMT (AUC: 0.96, p < 0.001 vs AUC 0.42, p = 0.212). Also, a comparison of CAC score score for CABG vs OMT revealed the same results (AUC: 0.96, p< 0.001 vs AUC: 0.42, p = 0.264). OMT vs CABG + PCA presented a cut-off value of 382 AU with a specificity of 90% and a sensitivity of 95%. OMT vs CABG presented a cut-off value of 530 AU with a specificity of 89% and a sensitivity of 95%. In conclusion, CAC score has a good predictability and sensitivity in determining the outcome and can be a promising tool to guide therapy in high risk patients, mainly regarding medical vs surgical treatment for coronary artery disease.
