Prognostic Role of High Sensitivity Troponin During Follow up in the Evolution of Acute Myocarditis — PROGNOSTIC  

Myocarditis Clinical Trial

Official title: Prognostic Role of Troponin Dosed at 3 to 6 Months in the Evolution of Acute Myocarditis

Status Not yet recruiting

Clinical Trial Summary

The goal of this observational study is to observe if ultra-sensitive troponins (us) measurement between 3 and 6 months after the acute event will be sensitive enough to dispense with all other examinations, particularly cardiac magnetic resonance imaging (MRI), in patients suffering from myocarditis. The investigators will collect patient events by telephone, once a year for 4 years.

Clinical Trial Description

Myocarditis is a frequent pathology with a heterogeneous initial clinical presentation. The long-term course of the disease is variable, with the possibility of healing and recovery, but also the likelihood of long-term deterioration, with the development of true dilated cardiomyopathy. While diagnostic criteria in the initial phase are well codified, notably with cardiac MRI, follow-up methods are less standardized. Re-evaluation between 3 and 6 months is not carried out by all teams, and if it is, the examinations performed vary from one team to another. Grenoble team has demonstrated the prognostic role of MRI reassessment at 3 and 6 months. It is also common to measure troponins to detect chronic myocarditis. However, this assay has evolved over time with the advent of ultra-sensitive troponins (us). These appear to be much more sensitive, and this increased sensitivity may lead to a change in care strategies. For example, in the management of chest pain in emergency departments before the era of us troponins, the use of coronary CT scans improved patient management. This benefit of imaging has disappeared since the advent of troponin us. The hypothesis of investigators is that troponin us measurement between 3 and 6 months after the acute event will be sensitive enough to dispense with all other examinations, particularly cardiac MRI, in order to identify patients at risk of poor prognosis. ;
