TABLE 2.

Cox proportional hazards model for death in patients with non-ST elevation myocardial infarction (NSTEMI) undergoing either percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG)

	Hazard ratio	95% Confidence interval	P value
CABG (in reference to PCI)	0.59	0.46–0.76	<.001
Age, y	1.04	1.03–1.05	<.001
Left ventricular ejection fraction	0.98	0.97–0.99	<.001
Creatinine	1.17	1.08–1.27	<.001
Chronic lung disease	1.64	1.32–2.04	<.001
Cerebrovascular disease	1.47	1.20–1.81	<.001
End-stage renal disease	1.89	1.15–3.12	.013
Diabetes	1.45	1.19–1.77	<.001
Cancer	1.71	1.36–2.15	<.001
Peripheral artery disease	1.43	1.15–1.77	.001

Note: Variables included in the model but not significant: prior PCI, smoking, race, hyperlipidemia, prior MI, body mass index, body surface area, completeness of revascularization, number of diseased vessels, liver disease, hypertension, heart failure.
