RESUMO
OBJECTIVE: To determine the prevalence of renal artery disease and to correlate the underlying risk factors like age, sex, diabetes, hypertension, urea and creatinine in patients who have undergone angiogram for cardiovascular diseases. METHODS: Retrospective analysis of the reports of angiogram of patients who have undergone cardiac catheterization in Vijaya Heart Foundation for cardiovascular diseases. RESULTS: The prevalence of renovascular stenosis is 12.4%. Prevalence of hypertension and diabetes in the group of patients with renovascular stenosis compared with group having coronary artery disease is not statistically significant (p > 0.8). Univariate and multivariate logistic identified age, diabetes, hypertension and urea as independent predicators of renal artery stenosis; while variables like sex and serum creatinine were not associated. CONCLUSION: High prevalence of unsuspected renovascular abnormalities is found in patients who undergo angiography for cardiovascular disease. Factors like age, diabetes, hypertension and urea could be clinical predicators of renal artery stenosis. Hence renal arteries should be visualized routinely in patients undergoing coronary angiogram for cardiovascular disease.
