ABSTRACT: Chronic renal disease (CKD) is recognized as a worldwide public health problem. Traditional risk factors for CKD are also present in coronary artery disease (CAD). The purpose of this study is to examine the prevalence and characteristics of risk factors for CKD in the population with CAD. Renal function was evaluated in 527 patients with CAD in order to assess characteristics of the incidence, risk factors for CKD in the population with CAD. In the present study in order to concentrate on evaluation for eGFR of the patients with CAD proteinuria is not included in the definition of CKD. Univariate analysis demonstrated that the major risk factors associated with CKD in the patients with CAD were age (P ≤ 0.001), smoking (P = 0.016), diabetes mellitus (P = 0.021), hypertension (P ≤ 0.001), and systolic blood pressure (P = 0.004). The percentages of patients with both hypertension and diabetes mellitus were significantly greater in the CKD3-4 group (P < 0.001). The results of multivariable analysis showed that hypertension (OR 1.925, 95% CI 1.196-3.098, P = 0.007), diabetes mellitus (OR 1.744, 95% CI 1.044-2.914, P = 0.034) and serum uric acid (OR 1.008, 95% CI 1.006-1.010, P ≤ 0.001) were independent risk factors for reduced eGFR. CKD is common and has a high prevalence in the population with CAD. Several risk factors are known to simultaneously affect heart and kidney. The patients with CAD may be considered as a high-risk population for CKD.
