Evaluation of the impact of chronic kidney disease on the survival of octogenarian patients submitted to percutaneous coronary intervention

ABSTRACT

Objective To evaluate the impact of chronic kidney disease on the survival of patients – 80 years of age undergoing percutaneous coronary intervention (PCI) in the long term. Methods 273 subjects who underwent PCI between January 2010 and January 2016 were divided into four categories (1) stable angina (SA) and creatinine clearance – 30 (n = 24); (2) patients with SA and CrCl <30 (n = 70); (3) patients with acute coronary syndrome (ACS) and CrCl – 30 (n = 51); (4) patients with ACS and ICC <30 (n = 128). Mortality curves were evaluated using the Kaplan-Meier method and differences between groups were compared by log-rank statistic. Multivariate analysis was performed using the Cox proportional hazards method. The 4 groups were compared and the survival between the groups was evaluated. Results Octogenarian patients with CrCl <30 with SA and ACS have lower long-term survival (p < 0.0001). Conclusion CKD has a worse long-term prognosis for patients undergoing PCI.
