Ad hoc percutaneous coronary intervention in patients with stable coronary artery disease: A report from the National Cardiovascular Data Registry CathPCI Registry.

UNLABELLED: Percutaneous coronary intervention (PCI) may be performed in the same procedure as diagnostic coronary angiography (ad hoc PCI). This study aimed to evaluate current rates of ad hoc PCI use and associated risks of adverse outcomes in patients with stable coronary artery disease (CAD). METHODS: We identified 550,742 patients with stable CAD who underwent PCI in the National Cardiovascular Data Registry CathPCI Registry from 2009 to 2017. We compared in-hospital bleeding, acute kidney injury (AKI), and mortality between patients receiving ad hoc versus non-ad hoc PCI using logistic regression with inverse probability weighted propensity adjustment. RESULTS: Between 2009 and 2017, 82.9% of patients underwent ad hoc PCI. Patients who did not undergo ad hoc PCI had higher prevalence of peripheral vascular disease, heart failure, chronic kidney disease, and coronary artery bypass graft. Ad hoc PCI was associated with lower bleeding risk (adjusted odds ratio [aOR] 0.83, 95% CI 0.79-0.87) but no differences in risks of AKI (aOR 0.95, 95% CI 0.90-1.00) or mortality (aOR 1.09, 95% CI 0.97-1.23) compared with non-ad hoc PCI. Ad hoc PCI was associated with AKI risk in patients with glomerular filtration rate <30 mL/min (interaction P < .001), mortality risk in multivessel PCI (interaction P = .031), and risks of AKI and mortality in PCI of chronic total occlusions (interaction P = .045 and .002, respectively). CONCLUSIONS: Ad hoc PCI is extremely common among US patients with stable CAD and is associated with lower bleeding risk but no differences in risks of AKI or mortality compared with non-ad hoc PCI.
