0261 : Frequency of coronary artery disease in patients with rheumatic valvular heart disease: Moroccan experience

Abstract

The prevalence of coronary artery disease (CAD) in patients with valvular heart disease varies widely between developed and in developing countries. This is likely due, at least in part, to significant differences in etiology: rheumatic valvular heart disease is the most important cause of this pathology in Morocco. to estimate the prevalence of coronary artery disease (CAD) in rheumatic valvular heart disease (RVHD) and to evaluate its interest as a preoperative exploration cause of the constraints of cost, appointments, and risks in our context. Also we studied risk factors prediction of significant coronary artery disease in patients with RVHD, and discussed other preoperative exams to explore coronary arteries. From 01/01/2011 to 31/12/2012, 80 patients underwent coronary angiography at the University Hospital cardiac catheterization laboratory of Casablanca prior to planned RVHD surgery. Data analyses were performed using Epi Info, Version 6.04. The majority of patients were men (58.75% vs. 41.25%). The prevalence of Coronary Artery Disease found was 20%. These patients were all over the age of 55 years. The rate of hypertension was high 62.5% while only 37.5% were current smokers and 75% of the patients had more than one cardiovascular risk factor. Chest pain was found in 12.5%. 38% had mitral valvular disease, 38% had aortic valvular disease and 30% both. The analysis showed that in our population, age and systemic arterial hypertension (SAH) were the most related to CAD in rheumatic valvular disease. the prevalence of CAD among RVHD patients is low. Gender, age and SAH were identified as being strongly associated with the presence of CAD in our population.
