Coronary artery disease in patients undergoing coronary angiography pre-valve surgery.

Abstract

Objective: This study aimed to determine the incidence of CAD in patients undergoing coronary angiography prior to valve surgery and identify associated risk factors. Study Design: Retrospective study. Setting: Conducted on patients who underwent coronary angiography before valve surgery. Period: 1^st January 2022 to 31^st December 2024. Methods: CAD was defined as ≥50% stenosis in a major coronary artery. Demographic, clinical, and angiographic data were analyzed using SPSS version 22. Results: Among 80 patients, (07)8.8% had significant CAD, with higher prevalence in patients with mitral valve disease. The most commonly affected vessel was left circumflex artery. Risk factors such as hypertension (HTN), diabetes mellitus (DM), and smoking were significantly associated with CAD. Conclusion: A substantial proportion of patients scheduled for valve surgery have concomitant CAD, emphasizing the need for routine preoperative angiography. Risk stratification based on clinical factors may help identify high-risk patients.
