 Clinical outcomes in patients with ST segment elevation myocardial infarction with preserved left ventricular systolic according to treatment at discharge and during follow-up in propensity matched population. Figures are numbers (percentage) of patients and hazard ratios (95% confidence interval)

Propensity matched population	Angiotensin receptor blocker	Comparison group	Adjusted* HR (95% CI)	P value
Comparison with ACE inhibitor (n=1175 in each group
Cardiac death or MI	21 (1.8)	23 (2.0)	0.65 (0.30 to 1.38)	0.65
All cause death	32 (2.7)	18 (1.5)	1.23 (0.59 to 2.56)	0.58
Cardiac death	15 (1.3)	11 (0.9)	1.14 (0.41 to 3.15)	0.80
Myocardial infarction	7 (0.6)	12 (1.0)	0.30 (0.08 to 1.09)	0.07
Comparison with no renin angiotensin system blocker (n=803 in each group)
Cardiac death or MI	14 (1.7)	25 (3.1)	0.35 (0.14 to 0.90)	0.03
All cause death	21 (2.6)	23 (2.9)	0.81 (0.36 to 1.85)	0.62
Cardiac death	10 (1.2)	13 (1.6)	0.47 (0.14 to 1.56)	0.22
Myocardial infarction	4 (0.5)	12 (1.5)	0.25 (0.05 to 1.18)	0.08

MI=myocardial infarction.

*Adjusted for use of β blocker at discharge.
