|Abstract:||Background: Patient selection and procedural characteristics continue to evolve in percutaneous coronary intervention (PCI). Australian data on long-term trends and outcomes are limited. This study aimed to identify long-term temporal trends in patient characteristics and outcomes in a large Australian PCI cohort. Methods: We analysed data from 41,146 PCI procedures included in the multi-centre Melbourne Interventional Group registry to determine trends in patient characteristics, procedural practices and outcomes from 2005 to 2018. Procedures were divided into 2-yearly periods for trends analysis. Results: Temporal trends in patient characteristics showed increases in age, proportion of males, rates of obesity, insulin-requiring diabetes mellitus, current smoking, obstructive sleep apnoea and prior PCI (all Ptrend < 0.01). Increases in the proportion of ST-elevation myocardial infarction, cardiogenic shock or out-of-hospital cardiac arrest (OHCA) were observed, and CathPCI National Cardiovascular Data Registry mortality risk scores increased over time (all Ptrend < 0.01). Use of radial access and drug-eluting stents increased, and lesions treated were more frequently ostial, left main or ACC/AHA type B2/C in recent years (all Ptrend < 0.01). In contrast, major bleeding and no reflow rates declined, however 30-day mortality, 12-month mortality and rates of stroke increased (all Ptrend < 0.01). Rates of vascular complications and 30-day target vessel revascularisation remained similar. In multivariable analysis, 2-yearly time periods were not independently associated with risk of 30-day mortality or 30-day MACE. Conclusions: Over the last 14 years, Australian PCI procedural complexity and patient risk profiles have increased. Higher mortality rates appear to relate to increased patient risk profile rather than procedural factors.|
