They were divided into two groups, according to whether or not they suffered CKD. There were 254 cases in the CKD group (31.2%), while there were 560 cases (68.8%) in the control group. The clinical characteristics, coronary artery lesions, and major adverse cardiac and cerebrovascular events (MACCE) of the two groups were compared, and the relationship between risk factors and MACCEs was analyzed by multivariate logistic regression.Results: Compared with the control group, the CKD group had more severe coronary artery stenosis, expressed as the more diseased arteries (2.15 ± 0.82 vs 1.87 ± 0.83, p = 0.001), a high incidence of three diseased arteries (42.0% vs 28.3%, p = 0.001), and a higher Gensini score [37 (18.6, 66) vs 27.5 (12, 52.5), p = 0.009]. The one-year post-implant incidence of MACCE was higher in the CKD group compared with the control group (17.6% vs 9.9%, p = 0.006).Conclusion: CKD appears to be an important predictor for the prognosis of CAD.Keywords: chronic kidney disease, coronary artery disease, Gensini score, major adverse cardiac and cerebrovascular events
