Percutaneous coronary interventions in Chinese mainland 2008.

Percutaneous coronary intervention (PCI) developed rapidly in Chinese mainland in recent years. We collected data on PCIs performed in Chinese mainland in 2008 and analyze the causes of the differences among provinces in PCI development. 182,312 PCIs were performed in 1061 hospitals in 2008. The population-adjusted PCI rate was 137.28 procedures per million inhabitants. PCIs in different provinces had positive correlation with local per capita gross domestic product (GDP) (B=0.06, P<0.05) and with the hospitals which had completed over 100 procedures per year (B=434.23, P<0.05), and had negative correlation with local population (B=0.49, P<0.05).
