Prospective observational national multicentric study in 26 centres. Between june 2014 and october 2018 The investigators collected data about baseline characteristics, first recourse, in-hospital places of care and places of hospitalizations. Lengths of care and lengths of hospitalization.

Collected data of each patient were reported on a specific assessment tool. The investigators ran a univariate analysis and logistic regression between steps of the care pathway and in-hospital mortality. The main result was validated by an analysis with a propensity score: association between a hospitalization in cardiology and in-hospital mortality.
