Table 4: Summary of Results From the COURAGE Trial.

Year	Patients (n)	Participants	Primary outcome	Assigned groups, (patients [n])		Follow-up duration	PCI treatment	Primary outcome (events [n])		Hazard ratio for PCI (95 % CI)	P value
				PCI + OMT	OMT alone			OMT plus routine PCI	OMT plus bailout PCI
2007	2,287 of 35,539 patients screened	Stable angina or objective evidence of ischaemia or angina with coronary stenosis ≥80 %	Death from any cause Non-fatal MI	1,149 (total randomised) 1,077 (PCI attempted)	1,138	Median: 4.6 years (IQR 3.3–5.7)	BMS (n=1.046) (97 %) DES (n=31) (3 %)	211	202	1.05 (0.87–1.27)	0.62

BMS = bare-metal stent; DES = drug-eluting stent; IQR = interquartile range; MI = myocardial infarction; OMT = optimal medical therapy; PCI = percutaneous coronary intervention. Source: Boden, et al. 2007
