Sammanfattning
BACKGROUND : Acute myocarditis is a serious condition that is challenging to diagnose. Recent developments in contrast-enhanced cardiac magnetic resonance imaging (ce-MRI) enable visualization of myocardial damage in patients with myocarditis. The objective of this study was to identify patients in whom ce-MRI could be useful to reach such a diagnosis.
METHODS : We reviewed data from 37 patients referred to ce-MRI with suspected acute myocarditis at Stavanger University Hospital from July 2004 to May 2007.
RESULT : 20 patients had epicardial contrast enhancement compatible with myocarditis. The contrast enhancement was focal and most frequently localized to the inferolateral wall (n = 12). No patient with Troponin T < 0.1 microg/L (n = 7) showed epicardial contrast enhancement. It was not possible to distinguish patients with acute myocarditis from the other patients on the basis of clinical signs, symptoms, C-reactive protein levels, ECG- or echocardiography.
INTERPRETATION : Ce-cardiac MRI is important in the diagnosis of acute myocarditis. If troponin T levels are < 0.1 microg/L during the acute phase, it is unlikely that a contrast enhancement pattern will be compatible with myocarditis.
