Abstract

This study evaluated the relationship between the severity of coronary artery disease (CAD) and traditional coronary risk factors, metabolic syndrome, and chronic kidney disease (CKD). Three hundred and forty-three patients (35–90 years of age) with initial diagnosis of CAD were separated into two groups: 165 patients with single-vessel coronary artery disease (SVD group) and 178 patients with multivessel coronary artery disease (MVD group). We compared the risk factors for CAD between the two groups. An adjusted multivariate analysis showed that only CKD was associated with MVD (odds ratio, 2.85; 95% confidence interval [CI], 1.76–4.63; P = 0.00002). Next, the relationship between the severity of CAD, CKD, and the incidence of subsequent major adverse cardiac event (MACE) was investigated in 338 patients during the patient follow-up. The risk of MACE was approximately threefold higher in the group with MVD and CKD stage of 3 or greater than in the group with SVD but without CKD stage of 3 or greater (adjusted hazard ratio, 3.40; 95% CI, 1.26–9.17; P = 0.016). A statistical analysis also suggested that having MVD and advanced CKD was a more powerful risk factor for MACE. The comparison of risk factors between patients with SVD and patients with MVD revealed that CKD was the most important risk factor for MVD. In addition, having MVD and advanced CKD together was a crucial risk factor for subsequent MACE. To reduce the progression of CAD and to improve the prognosis of patients with MVD, the renal status should therefore be carefully assessed during treatment for CAD.
