Impact of Peripheral Vascular Stiffness Assessment on Risk Prediction in Patients With Myocardial Infarction

Study Overview
=================
Brief Summary
-----------------
Risk assessment after myocardial infarction is critical in daily practice and evolution toward heart failure especially diastolic heart failure remains a key issue. All consecutive patients with myocardial infarction (either STEMI or NSTEMI but excluding type 2 MI) presenting at university hospital of Lille within 48 hours after symptom onset will be recruited in the RIGID-MI registry. The RIGID-MI study proposes to deeply evaluate at 1 month after MI: peripheral vascular disease, vascular stiffness, ventriculo-arterial coupling and other usual risk factors. The main objective is to identify clinical, biological and imaging parameters associated with poor prognosis, especially evolution toward diastolic heart failure, recurrence of MI, and bleeding.
