Risk Factors of Cardiac Death for Elderly Patients with Severe Chronic Kidney Disease after Percutaneous Coronary Intervention

Abstract

Aims: To identify risk factors for cardiac death of elderly and severe chronic kidney disease (CKD) patients with coronary atherosclerotic heart disease (CAHD) after percutaneous coronary intervention (PCI). Methods: 1010 CAHD-CKD patients over 60 years old who had CKD stage 3 or above and underwent PCI were followed up for at least 3 years. Cases of cardiac death were divided into groups. After univariate analysis of all variables, the variables with P 4.285 mmol/L OR = 1.44, 95%CI: 1.002∼2.069, P =.049, without statins OR = 2.015, 95%CI: 1.072∼3.789, P =.030. Conclusion: In elderly and serious CAHD-CKD patients after PCI, SVD PCI was a protective factor against cardiac death. However, SAP, CAHD-CKD combined with LEASO, K > 4.285 mmol/L, and no statins were independent risk factors of cardiac death for elderly patients with severe CKD after PCI.
