The study by Zheng and colleagues1 in this issue of JAMA Internal Medicine documents dramatic changes in the care of coronary artery disease (CAD) in China. From 2001 to 2011, the numbers of coronary artery catheterizations and percutaneous coronary interventions (PCIs) performed in urban Chinese hospitals increased 17-fold and 21-fold, respectively. In the United States, where these procedures are far more common, federal data2 show that the rates of diagnostic cardiac catheterizations fell from 54 to 40 per 100 000 population, and the rates of PCI decreased from 21 to 18 per 100 000 population between 1997 and 2011.
