Objective
CHA2DS2-VASc scores are validated tools for assessing stroke risk in patients with atrial fibrillation (AF). It is known that traditional risk factors for coronary artery disease and CHAD2 VASc score’s parameters are similar.We formulated the CHA2DS2-VASc-CAC score comprising coronary calcium score(CACS) in addition to the components of the CHA2DS2-VASc score and male instead of female gender as We evaluated multivariable risk assessment tools to identify those at high risk of severe CAD in patients who underwent computed tomography(CT).
Methods
The study population consisted of 131 patients who were clinically referred for noninvasive multislice computed tomographic coronary angiography for evaluation of coronary artery disease. Patients were classified as having no atherosclerosis –Group 1( n=36), nonobstructive atherosclerosis (luminal narrowing <50% in diameter)-Group 2 ( n=42), obstructive atherosclerosis (luminal narrowing ≥ 50%) in a single vessel,or obstructive atherosclerosis in the left main coronary artery and/or multiple vessels-Group 3.( n=53 ).After Patients’ CHA2DS2-VASc and CHA2DS2-VASc -CACS were calculated.
