CHA2DS2-VASc-HSF Score as a Predictor of Severity of Coronary Artery Disease in Patients Undergoing Coronary Angiography

Background: Cardiovascular atherosclerosis, particularly coronary artery disease (CAD), represents the main reason for death prematurely over the world. Risk stratification and prevention by risk factor modification are crucial aspects of CAD therapy. The CHADS2 and CHA2DS2-VASc scores are effective in determining the risk of thrombosis in non-valvular atrial fibrillation (AF). The current research aimed to determine the CHA2 DS2-VASc-HSF score as a predictor for CAD severity in CAD patients after coronary angiography.

Methods: This cross-sectional study was assessed on 100 patients who attended the coronary care unit and underwent coronary angiography. They were categorised into three groups: Group I: Low syntax scores (2-13), Group II: Intermediate syntax score (14-20), and Group III: High syntax score (21-40).

Results: Our study showed that the SYNTAX score revealed a statistically significant relation with patient's age, gender, and presentation. Regarding the medical history of the studied participant in relation to SYNTAX score, most patients reported a history of HTN, DM, Dyslipidemia, CHF, and previous history of vascular disease showed intermediate and high SYNTAX score in comparison to those with normal blood pressure, glucose level, lipid profile, no CHF history and those no previous history. SYNTAX score showed significant relation with ejection fraction and CHA2 DS2-VASc-HSF score of the patient. Significant low ejection fraction in high SYNTAX score patients compared to low SYNTAX score patients. Significant high average of CHA2 DS2-VASc-HSF score among those with high and intermediate SYNTAX score compared to those with low SYNTAX score.

Conclusions: CHA2DS2-VASc-HSF should be constituted as the ideal scoring scheme for predicting the severity of CAD. Risk scoring systems may be effective as predictors due to their simplicity and easy employment by physicians in ordinary practice without incurring additional costs.
