High-risk percutaneous coronary intervention (PCI) procedures are being performed in greater numbers, in older patients with multiple comorbidities, and increasingly in the setting of acute coronary syndromes. Estimating inpatient PCI mortality and MACE risk (mortality, Q-wave myocardial infarction, urgent coronary artery bypass grafting and stroke) is essential in informing decision-making, consent, and operator and institutional benchmarking. There are a number of currently available risk scores that are often applied interchangeably. We investigated if there was concordance between contemporary risk scoring systems for inpatient mortality and MACE following PCI in patients at low, moderate or high-risk in a 'real life' cohort, depending upon method of presentation (elective, urgent, emergency).
