Background and Objectives: Although several multicenter registries have evaluated percutaneous coronary intervention (PCI) procedures in Korea, those databases have been limited by non-standardized data collection and lack of uniform reporting methods. We aimed to collect and report data from a standardized database to analyze PCI procedures throughout the country. Materials and Methods: Both clinical and procedural data, as well as clinical outcomes data during hospital stay, were collected based on case report forms that used a standard set of 54 data elements. This report is based on 2014 Korean PCI registry cohort data. Results: A total of 92 hospitals offered data on 44967 PCI procedures. The median age was 66.0 interquartile range 57.0-74.0 years, and 70.3% were men. Thirty-eight percent of patients presented with acute myocardial infarction and one-Third of all PCI procedures were performed in an urgent or emergency setting. Non-invasive stress tests were performed in 13.9% of cases, while coronary computed tomography angiography was used in 13.7% of cases prior to PCI. Radial artery access was used in 56.1% of all PCI procedures. Devices that used PCI included drug-eluting stent, plain old balloon angioplasty, drug-eluting balloon, and bare-metal stent (around 91%, 19%, 6%, and 1% of all procedures, respectively). The incidences of in-hospital death, non-fatal myocardial infarction, and stroke were 2.3%, 1.6%, and 0.2%, respectively. Conclusion: These data may provide an overview of the current PCI practices and in-hospital outcomes in Korea and could be used as a foundation for developing treatment guidelines and nationwide clinical research.
