However, contemporary data remain limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The Japanese PCI (J-PCI) is a nationwide prospective registry covering most of the procedures performed within the country. PCI procedures in 2019 and 2023 were included and divided according to the indications: AMI versus non-AMI. The patterns of PCI procedures performed for AMI and non-AMI across all prefectures in Japan were evaluated. The associations of the non-AMI\/AMI ratio with population, area, and the number of PCI-capable centers per prefecture were also assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 494,746 PCI procedures were analyzed. The ratios between the highest and lowest prefectures were 4.0-fold in non-AMI and 1.9-fold in AMI in 2019 and 4.2-fold in non-AMI and 2.0-fold in AMI in 2023. The non-AMI\/AMI ratio was positively correlated with the ratios of the number of PCI-capable centers to population and area per prefecture.<\/jats:p>\n                  <\/jats:sec>\n
