Popis: Background: Percutaneous coronary intervention (PCI) is increasingly used as a treatment option for unprotected left main stem artery (unprotected left main stem percutaneous intervention) disease. However, whether patient outcomes have improved over time is uncertain. Methods: Using the United Kingdom national PCI database, we studied all patients undergoing unprotected left main stem percutaneous intervention between 2009 and 2017. We excluded patients who presented with ST-segment–elevation, cardiogenic shock, and with an emergency indication for PCI. Results: Between 2009 and 2017, in the study-indicated population, 14 522 unprotected left main stem percutaneous intervention procedures were performed. Significant temporal changes in baseline demographics were observed with increasing patient age and comorbid burden. Procedural complexity increased over time, with the number of vessels treated, bifurcation PCI, number of stents used, and use of intravascular imaging and rotational atherectomy increased significantly through the study period. After adjustment for baseline differences, there were significant temporal reductions in the occurrence of peri-procedural myocardial infarction (P Conclusions: Despite trends for increased patient and procedural complexity, in-hospital patient outcomes have improved after unprotected left main stem percutaneous intervention over time.
