Abstract

Objective: We sought to investigate the clinical and procedural characteristics in patients with a history of Renal Transplant (RT) and compare the outcomes with non-RT patients in two national cohorts of patients undergoing percutaneous coronary intervention (PCI).
Background: PCI in RT is challenging and complex with limited data around outcomes of RT compared to non-RT patients in the real world.
Methods: Data from the National Inpatient Sample (NIS) and British Cardiovascular Intervention Society (BCIS) were used to compare the clinical and procedural characteristics and outcomes of RT with non-RT patients undergoing PCI. The primary outcome of interest was in-hospital mortality.
Results: 0.2% in NIS and 0.3% in BCIS of PCI procedures between 2004-2014 and 2007-2014 were undertaken in patients with a history of RT. RT patients were younger, had a higher prevalence of congestive cardiac failure, hypertension, diabetes but similar use of drug eluting stent, intracoronary imaging and pressure wire studies compared to non-RT group. In the adjusted analysis, RT patients had increased odds of in-hospital mortality (NIS: OR 1.90 95%CI 1.41-2.57; BCIS: OR 1.60 95%CI 1.05-2.46) compared to patients without RT but no difference in vascular or bleeding events. Meta-analysis of the two datasets suggested an increase in in-hospital mortality (OR 1.79 95%CI 1.40-2.29) but no difference in vascular (OR 1.24 95%CI 0.77-2.00) or bleeding events (OR 1.21 95%CI 0.86-1.68).
Conclusion: This large collaborative analysis of two national database shows that patients with renal transplant are younger, more comorbid, and have increased mortality risk compared to general population undergoing PCI.
