Abstract 18398: Time Course of Cardiac Markers During Acute Myocarditis

Introduction: Acute myocarditis is an inflammatory process that leads to leak of intracellular components into the blood including cardiac markers. The time course of cardiac markers has been well established for acute coronary syndrome (ACS), but has not been described for myocarditis. While scientific statements recommend using troponin levels as guidance for diagnosis of myocarditis, studies have shown that troponin is only elevated in 1/3 of cases with biopsy proven myocarditis. We sought to evaluate the pattern of cardiac markers released during acute myocarditis to find a diagnostic pattern. Methods: During the years 2016/2017 a total of 52 patients with acute myocarditis, confirmed by cardiac resonance imaging (CMR), were included. Exclusion criteria were acute coronary syndrome, chronic myocarditis (symptoms > 10 days), concomitant myositis and status post cardiopulmonary resuscitation (n= 14). Blood samples were obtained in all patients upon admission. The following cardiac markers were sequentia...
