Independent Predictors of 1-Year Ischemic Outcomes

	Hazard Ratio (95% Confidence Interval)	p Value
All-cause death
rSS*	1.05 (1.03–1.08)	<0.001
Age (per 10-year increase)	1.44 (1.10–1.89)	0.008
Insulin-treated diabetes	3.66 (2.04–6.57)	<0.0001
Cardiac death
rSS*	1.06 (1.03–1.10)	<0.001
Insulin-treated diabetes	4.89 (2.39–10.00)	<0.0001
Renal dysfunction	2.23 (1.09–4.55)	0.03
Myocardial infarction
rSS*	1.02 (1.01–1.04)	0.003
Insulin-treated diabetes	1.41 (0.94–2.10)	0.09
Unplanned revascularization for ischemia
rSS*	1.04 (1.02–1.05)	<0.001
Age (10-year increase)	0.86 (0.78–0.96)	0.005
Insulin-treated diabetes	1.49 (1.02–2.17)	0.04
Baseline cardiac biomarker elevation or ST-segment deviation	0.68 (0.53–0.86)	0.002

The following variables were included in each model: 1) for all-cause death: rSS (continuous variable), age, diabetes, renal dysfunction, baseline troponin elevation, ST-segment deviation, baseline white blood count; 2) for cardiac death: rSS (continuous variable), age, diabetes, and renal dysfunction; 3) for myocardial infarction and unplanned revascularization: rSS (continuous variable), age, male, diabetes, current smoker, renal dysfunction, baseline troponin elevation, ST-segment deviation, prior myocardial infarction, prior percutaneous coronary intervention, baseline white blood count, baseline hemoglobin, and type of stent (drug-eluting stent vs. bare-metal stent).

rSS = residual Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score.
