Temporal trends in the use of angiography and revascularization by predicted mortality risk. Risk scores were determined using the modified ACTION Registry‐GWTG mortality risk score, as described in the Methods. One‐sided P values for Cochran‐Armitage trend tests for yearly changes in procedure rates for the U.S. vs South Korea by risk groups are listed sequentially. For the use of angiography, risk score ≤20: P = 0.0009 for US vs P = 0.0019 for South Korea; risk score 21–30: P = 0.0374 vs P = 0.0049; risk score 31–40: P = 0.0005 vs P = 0.0117; and risk score ≥40: P < 0.0001 vs P = 0.0014. For the use of revascularization, risk score ≤20: P = 0.0382 for US vs P = 0.1130 for South Korea; risk score 21–30: P = 0.0073 vs P = 0.0081; risk score 31–40: P = 0.4074 vs P < 0.0001; and risk score ≥40: P = 0.0013 vs P = 0.0004.
