Univariate and multivariate hazard ratio for outcomes

	Univariate		Multivariate
	HR (95% CI)	P value	HR (95% CI)	P value
Cardiovascular mortality
Baseline normal LVEF	1.00	–	1.00	–
Recovered LVEF	1.10 (0.39–3.08)	0.863	1.95 (0.52–7.34)	0.325
Persistently Reduced LVEF	3.89 (1.93–7.85)	< 0.001	7.49 (1.94–28.87)	0.003
HF rehospitalization
Baseline normal LVEF	1.00	–	1.00	–
Recovered LVEF	1.62 (0.80–3.30)	0.180	0.79 (0.34–1.86)	0.793
Persistently Reduced LVEF	9.66 (5.97–15.64)	< 0.001	3.54 (1.56–8.06)	0.003

Baseline normal LVEF was treated as reference. Multivariate adjusted for age, sex, hypertension, diabetes, chronic kidney disease, prior PCI, prior stroke, smoking, heart rate, SBP, Killip class II–IV, out-of-hospital cardiac arrest, peak troponin T, initial creatinine, multivessel disease, usage of IABP, TIMI flow 0–1 before PCI, baseline LVEF, ACEIs/ARBs at discharge, and β-blockers at discharge

HR hazards ratio, 95% CI 95% confidence interval, LVEF Left ventricular ejection fraction, HF heart failure, PCI Percutaneous coronary intervention, SBP Systolic blood pressure, IABP Intra-aortic balloon pump, TIMI Thrombolysis in Myocardial Infarction, ACEIs Angiotensin-converting enzyme inhibitors, ARBs Angiotensin II receptor blockers
