ABSTRACT
Background: To know the incidence of significant coronary artery disease in rheumatic valvular heart patients undergoing preoperative valve replacement surgery by coronary angiogram. This very important prognostic indicator after surgery if we miss the cad the morbidity and mortality was high. Aim: To assess the CAD-related RHD in various valve involvement and associated risk factors like systemic hypertension and diabetic mellitus. Materials and methods: In this study, we analyzed 100 patients undergoing preoperative coronary angiogram in our department to know the incidence of significant CAD. This study also detected a correlation between the CAD, various valve involvement, sex, comorbidities like DM, SHT and Dyslipidemia were analyzed and also the incidence of CAD with duration of disease, the age of the patients and associate with post CMC or PTMC. Results: In this study, out of 100 patients undergone preoperative coronary angiogram, 8 had significant CAD. 5 patients were male and 3 were female and involvement of valves LCX was 4, LAD was 2, RCA was 1 and LMCA was 1 (p-value <0.05). In this study, the incidence of CAD was high in patients had comorbidities like DM, SHT, and dyslipidemia. Insignificant CAD group 2 had SHT, 2 had DM, 2 had both DM and SHT remaining 2 had no comorbidities. This study showed 5 patients of Aortic valve disease and 3 patients of Mitral valve disease had significant CAD. Conclusion: From this study, the incidence of CAD in our department is 8% most common in males than females and Aortic valvular RHD patients are mostly affected than other valvular RHD. Incidence increased with Age and associated comorbidities.
