Abstract
Summary Atherosclerotic cardiovascular disease, especially coronary artery disease (CAD), remains the leading cause of premature death worldwide. Risk stratification and prevention by modification of risk factors is an important aspect of management of CAD. CHADS2 and CHA2DS2-VASc scores are useful for assessing risk of thromboembolism in non- valvular atrial fibrillation (AF). They include similar risk factors for the development of CAD and may be useful for the assessment of the severity of coronary artery lesions. To increase the likelihood of determining CAD severity, the CHA2DS2-VASc-HSF scorehas been used comprising male instead of female gender, hyperlipidaemia, smoking and family history in addition to the components of the CHA2DS2-VASc score. The SYNTAX Score is an established angiographic tool for grading the anatomic severity of coronary artery disease The aim of the study was to investigate the CHA2 DS2-VASc-HSF score as a predictor of the severity of CAD in patients with coronary artery disease after coronary angiography. Our study was conducted on 100 patients who attended to the coronary care unit at Tanta university hospitals from May 2020 to November 2020 and underwent coronary angiography. According to their syntax score, the patients were divided into three groups: group I: Low syntax scores (2-13) group II: Intermediate syntax score (14-20)group III: High syntax score (21-40)
