Background: There are several methods for screening of cardiovascular diseases, among these, coronary artery calcium score (CACS) by coronary computed tomography angiography (CCTA) which is widely used as a screening method.
Aim: The aim of this work is to compare the total calcium as detected by echocardiography, ABO system and neutrophil lymphocyte ratio (NLR) as a predictor of coronary artery calcium score detected by multi-slice CT (MSCT).
Patients and Methods: 128 patients referred for MSCT angiography, with suspected coronary artery disease from January 2018 to August 2018. Patients were divided into three groups according to coronary artery calcium as measured by MSCT (group 1: CACS =0-99, group 2: CACS = 100-399 & group 3: CACS ≥400). Echogardiography, ABO system, CBC (NLR) and MSCT coronary angiography were done for all patients.
Results: There was statistically significant difference between patients with blood group A and other blood groups as regarding higher coronary calcium scores (by MSCT) (p < 0.0001). There was positive significant correlation between cardiac calcium score (by echocardiography) and CAC score (r= 0.712 , p < /p>
