Table 2: Results of the Cox Regression Model for AF Compared with Sinus Rhythm (Reference Variable) with All-cause Mortality as the Endpoint.

Cox Regression Model	Unadjusted Model	Adjusted for Sex and Age	Fully Adjusted*
HR [95% CI]	3.18 [2.42–4.17]	1.88 [1.42–2.48]	1.40 [1.05–1.87]
p-value	<0.001	<0.001	0.023

*Adjusted for: sex, age, BMI, type of MI (ST-segment elevation MI, non-ST-segment elevation MI, bundle branch block), typical chest pain, left ventricular ejection fraction ≤30%, arterial hypertension, diabetes, smoking status, hyperlipidaemia, creatinine level, peak creatine kinase myocardial band level, bypass surgery, percutaneous coronary intervention, combination of four evidence-based drugs for myocardial infarction at hospital discharge (antiplatelet agents, β-blockers, angiotensin-converting enzyme inhibitors/angiotensin II inhibitors, statins).
