 Hazard ratios (95% confidence intervals) for death in survivors of an acute myocardial infarction (AMI) after stepwise addition of risk markers: Perth MONICA cohort 1984-93

	1988-90 v 1984-7	1991-3 v 1984-7
Death at one year in 28 day survivors
Unadjusted	0.77 (0.53 to 1.11)	0.60 (0.40 to 0.90)
Adjusted for:
Demographic factors (age and sex)	0.76 (0.53 to 1.11)	0.61 (0.40 to 0.91)
Above plus coronary risk factors*	0.76 (0.53 to 1.11)	0.60 (0.40 to 0.91)
Above plus disease severity†	0.82 (0.56 to 1.19)	0.64 (0.42 to 0.96)
Above plus clinical complications during admission‡	0.83 (0.57 to 1.20)	0.66 (0.44 to 1.01)
Above plus medical treatment in hospital§	1.10 (0.72 to 1.69)	1.00 (0.61 to 1.65)
Death at 12 years in one year survivors
Unadjusted	0.88 (0.76 to 1.02)	0.72 (0.62 to 0.84)
Adjusted for:
Demographic factors (age and sex)	0.88 (0.76 to 1.01)	0.72 (0.62 to 0.84)
Above plus coronary risk factors*	0.88 (0.76 to 1.01)	0.71 (0.61 to 0.82)
Above plus disease severity†	0.93 (0.80 to 1.07)	0.73 (0.63 to 0.85)
Above plus clinical complications during admission‡	0.94 (0.82 to 1.09)	0.74 (0.63 to 0.86)
Above plus medical treatment in hospital§	1.19 (1.00 to 1.40)	0.96 (0.79 to 1.16)
Above plus CAR within 12 months	1.38 (1.16 to 1.63)	1.15 (0.94 to 1.40)

CAR=coronary artery revascularisation.

*History of diabetes, history of hypertension, and current or recent smoker.

‡Heart failure, cardiogenic shock, tachycardia>100 beats/minute, systolic blood pressure <100 mm Hg within 28 days of admission to hospital.
