Baseline characteristics

No ECG change, early revascularisation (n=34)No ECG change, early conservative (n=67)0.5 mm ST depression/ T wave inversion, early revascularisation (n=45)0.5 mm ST depression/ T wave inversion, early conservative (n=63)≥1 mm ST depression, early revascularisation (n=36)≥1 mm ST depression, early conservative (n=86)
†p<0.05, ST depression ≥ 1 mm invasive v conservative.
‡p<0.05, ST depression ≥1 mm v other ECG groups.
*p < 0.005, no ECG change v others.
CABG, coronary artery bypass graft; CK, creatine kinase; conservative, medical management; MI, myocardial infarction; PCI, percutaneous coronary intervention.
