Post-PCI acute heart failure is an independent predictor of long-term mortality in patients with chronic kidney disease.

Abstract Background This study aimed to clarify the association of post-percutaneous coronary intervention (PCI) acute heart failure (AHF) with all-cause long-term mortality in patients with chronic kidney disease (CKD). Methods In this prospective, observational study, 610 patients with CKD and coronary artery disease (CAD) undergoing PCI were included in the final analysis. Patients were divided to the non post-PCI AHF group (n = 557) and the post-PCI AHF group (n = 53). The diagnosis of post-PCI AHF was based on symptoms, prior cardiovascular history, and potential cardiac and noncardiac precipitants. Results The overall incidence of post-PCI AHF was 53/610 (8.7%). The incidence of all-cause long-term mortality was significantly higher in the post-PCI AHF group than in the non post-PCI AHF group (50.9% vs 23.2%, P  Conclusions In patients with CKD and CAD undergoing PCI, post-PCI AHF is the strongest predictor of all-cause long-term mortality.
