The current guideline definitions of appropriate, uncertain and inappropriate use of percutaneous coronary intervention (PCI) in patients with non-acute coronary syndromes are based on relative scores allocated to differing clinical scenarios as assessed by an expert panel. The clinical outcomes of interventions deemed appropriate or uncertain have not been studied.
We identified 1728 patients (1164 males, 67%) with stable coronary artery disease who underwent PCI deemed appropriate (n= 938, 54%) or uncertain (n=790, 46%) in 2010 and examined their clinical outcomes.
Baseline demographics were similar between patients whose PCI were considered appropriate and those considered uncertain. Angiographic characteristics between the two groups were also similar with 1 (IQR 1-2) lesions treated per patient. PCI success rates of 99% were comparable between both groups with similar in hospital outcomes. There was no difference in survival outcomes of death, CABG, target lesion or vessel revascularization in 499 (IQR 455-531) days follow up between patients whose PCI were classified as uncertain or appropriate.
Similar outcomes post- PCI irrespective of appropriate or uncertain classification were found. These findings may have important implications in contemporary practice where appropriate use criteria are increasingly used to govern clinical decision making and allocation of medical resources.
