OBJECTIVE: to estimate the prevalence of coronary artery disease (CAD) in valvular heart disease of rheumatic (RVHD) and non-rheumatic (NVHD) etiology, assessing possible predictive factors for the presence of CAD.
METHODS: This is a cross-sectional study of a series of cases obtained from a pre-defined population, wherein 1,412 patients referred for heart surgery of any etiology were evaluated. Of these, 294 primary heart disease patients aged > or =40 submitted to cinecoronary arteriography (CA) were identified and studied.
RESULTS: patients with RVHD presented lower prevalence of CAD (4%) when compared to NVHD (33.61%), p<0.0001. The logistic regression analysis showed that age, typical angina-like chest pain (TACP), systemic arterial hypertension (SAH), diabetes and dyslipidemia were significantly related to CAD, and that the rheumatic etiology was not a disease determinant. Smoking and gender were clinically important in CAD, although not statistically significant. In the whole group, the Log-linear analysis showed that, regardless of the etiology, gender, age > or =55, SAH, TACP, diabetes and dyslipidemia were all related directly to CAD, with the latter three being the most important variables for the disease.
CONCLUSION: the prevalence of CAD among RVHD patients is low, whereas it is high among NVHD patients; the rheumatic etiology does not seem to have any beneficial effects on the prevalence of CAD; gender, age, SAH, TACP, dyslipidemia and diabetes were identified as being strongly associated with the presence of CAD. It is possible to define the criteria that indicate the need for pre-surgical CA in heart valve replacements, so that the standard indication after the age of 40 years can be avoided.
