It was observed that asymptomatic patients with a LVEF>45% after one year can safely be referred to the GP with mortality rates after STEMI that come close to the rate in the general population.The second part focused to identify high-risk subpopulations to improve risk stratification. Despite current standards of care aimed at achieving targets for LDLc and other traditional risk factors, STEMI patients remain at high risk of new cardiovascular events. Valuable effort should therefore be made to further reduce residual cardiovascular risk by using additional more discriminating and more refined treatments targets like apoB and apoB/apoA1 ratio. Furthermore, novel biomarkers were identified to improve risk stratification and select high risk sub-populations. GDF-15, a more general marker for disease severity in STEMI patient demonstrated to have an additional prognostic value beyond identified risk factors and other cardiac biomarkers such as cTn and NT-proBNP.Lastly, the third part of this thesis showed that a dedicated pre-hospital triage protocol is an effective tool to select patients for admission at the cardiac emergency department. Overcrowding is a major public health problem and this thesis shows that the introduction of dedicated cardiac emergency departments can potentially reduce the caseload of the general emergency department.
