Objective: To determine the prevalence of coronary artery disease in patients undergoing valve surgery for rheumatic heart disease between age 40-50 years, usefulness and indication of pre-operative coronary angiography. Methods: This is an observational prospective study that took place in 2 hospitals in the period starting from 2013 to 2015. We included 454 rheumatic patients that were admitted for mitral, aortic or double valve surgery and had a coronary angiogram in their regular pre-operative workup. All coronary angiographies are to detect significant coronary artery disease (CAD) of >75% related to pre-operative coronary risk factors (DM, hyperlipidemia, smoking, gender, age, hypertension and family history) of age ranging from 40 to 50 years. Results: No correlation between rheumatic heart disease in this age group and CAD as only 1.76% had the significant stenosis. Male gender, family history of CAD, age above 45 years, hypertension and smoking showed significant correlation with the CAD in this study. Conclusion: Our results suggest that the overall prevalence of coronary artery disease in patients undergoing rheumatic valve surgery in our population is not comparable with the prevalence reported in international data. So this study aims to be the cornerstone for starting our own guidelines.
