 The study has two aims. First to describe the real-world incidence of HF following MI. Differences between clinically relevant groups e.g. men and women, and patients with or without - ST-elevation MI, will be examined. Second, to identify prognostic factors for developing HF in patients who had an MI. The following panels of prognostic factors will be investigated: sociodemographic; anthropomorphic and haemodynamic; behavioural; co-existing conditions cardiovascular and non-cardiovascular; blood biomarkers; prescribed secondary preventive medication.
