The first aim of this trial is to assess the long-term prognostic value of Omega-3 index, which is a measure of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) relative to other fatty acids in the erythrocyte membrane, in an unselected, regional multicenter observational study of 982 chest pain patients admitted to the emergency unit, employing blood samples collected at admission.

The second purpose of this study is to evaluate the prognostic utility of vitamin D in the same population.

The third purpose of this study is to assess the incremental prognostic value of B-type natriuretic peptide (BNP) and high-sensitive C-reactive protein (hsCRP).
