Comparative Trends in Percutaneous Coronary Intervention in Japan and the United States, 2013 to 2017

Adoption of the results of large-scale randomized controlled trials in percutaneous coronary intervention (PCI) may differ internationally, yet few studies have described the potential variations in PCI practice patterns. Using representative national registries, we compared temporal trends in procedural volume, patient characteristics, pre-procedural testing, procedural characteristics, and quality metrics in the United States and Japan. The National Cardiovascular Data Registry CathPCI was used to describe care in the United States, and the J-PCI was used to assess practice patterns in Japan (numbers of participating hospitals: 1,752 in the United States and 1,108 in Japan). Both registries were summarized between 2013 and 2017. PCI volume increased by 15.8% in the United States from 550,872 in 2013 to 637,650 in 2017, primarily because of an increase in nonelective PCIs (p for trend
