Abstract: Background: The Melbourne Interventional Group (MIG) Registry has collected data on percutaneous coronary intervention (PCI) outcomes as practice has evolved over the last 15 years. We aim to describe the current MIG PCI cohort at large and to identify contemporary trends in Australian PCI. Methods: Data were prospectively collected on 34,797 consecutive PCI procedures at six Victorian public hospitals from 2005 to 2017. Patients were divided into three time groups (A: 2005–2008, B: 2009–2013, C: 2014–2017) for trends analysis. Results: Overall cohort mean age was 64 ± 12 years, 77% were male. Across the three time periods, total procedural numbers remained similar, but with increasing rates of STEMI, out-of-hospital cardiac arrest (OHCA), and cardiogenic shock (CS) as indication for PCI (all p < 0.001). Drug-eluting stents were more frequently used (A: 40%, C: 71%, p < 0.001), radial access more frequently used (A: 5%, C: 50%, p < 0.001), and treated lesions were more frequently of higher complexity (ACC/AHA type B2/C, A: 50%, C: 58%, p < 0.001). Hospital length-of-stay and 30-day mortality slightly increased, while 12-month mortality remained stable. 30-day mortality among common subtypes was 0.2% following elective PCI, 0.9% following NSTEMI, 2.3% post STEMI (in the absence of CS or OHCA), and 33% in patients with OHCA or CS. Long-term mortality for patients surviving to 30-days was similar between indication subtypes out to 13 years. Conclusions: Patient selection, procedural technique and outcomes continue to evolve among PCI cohorts. 30-day mortality after PCI has slightly increased and may relate to increased presentation with OHCA and CS.
