Valvular deposits of calcium quantified by transthoracic echocardiography are associated with the occurrence of systemic atherosclerotic disease, but its prognostic value and influence of associated cardiovascular risk factors have not been defined yet. Objectives: To correlate the valvular cardiac calcium index by transthoracic echocardiography with cardiovascular risk factors and presence of coronary artery disease (CAD). Methods: We selected 203 patients (61.2 ± 14.3 years; 57.6% females) who underwent transthoracic echocardiography with cardiac calcium index quantification. The presence or absence of CAD, hypertension, diabetes mellitus (DM), dyslipidemia, and smoking was assessed. Results: Age above 65 years (p < 0.001) and the presence of hypertension (p < 0.001) showed a significant correlation with the presence of cardiac calcification, whereas DM (p = 0.056) and CAD (p = 0.08) showed only a trend toward a correlation with calcification. Mitral valve calcification alone correlated significantly with age above 65 years (p < 0.001), presence of CAD (p = 0.004), hypertension (p = 0.054), and DM (p = 0.07). On multivariate analysis, CAD (odds ratio [OR] 3.39, 95% confidence interval [95%CI] 1.58-7.29, p = 0.002) and age > 65 years (OR 1.05, 95%CI 1.02-1.08, p = 0.003) correlated significantly and independently with mitral valve calcification. Aortic valve calcification alone showed no correlation with the presence of CAD (p = 0.435), but correlated significantly with age above 65 years (p < 0.001) and hypertension (p < 0.001). On multivariate analysis, only age (OR 1.1, 95%CI 1.06-1.14, p < 0.001) remained independently and significantly correlated with aortic calcification. Conclusion: Age above 65 years and hypertension were independent risk factors for the presence of valvular cardiac calcification, with mitral valve calcification alone emerging as significantly and independently associated with the presence of CAD.
