The effect of tobacco smoking and treatment strategy on the one-year mortality of patients with acute non-ST-segment elevation myocardial infarction

Table 2 Hazard ratios (HR) of death in patients with NSTEMI (n = 381) during one-year follow-up using multiple Cox proportional hazards regression (Model 1).

	HR	95% CI	p-value
Invasive strategy	0.80	0.50-1.27	0.34
Age per year	1.05	1.02-1.08	< 0.001
S-creatinine per unit (μmol/L)	1.005	1.003-1.007	< 0.001
Current smoking	2.61	1.43-4.79	0.002
Previous LVSD*	1.63	0.97-2.75	0.064
Statin during hospitalization	0.46	0.29-0.71	0.001
Aspirin during hospitalization	0.57	0.35-0.90	0.017
Interaction term (current smoker/strategy)	0.22	0.06-0.82	0.024

*Defined as previous left ventricular ejection fraction < 40%.
CI, confidence interval; LVSD, left ventricular systolic dysfunction; NSTEMI, non-ST-segment elevation myocardial infarction.
