The Difference

Background: Acute myocarditis and acute myocardial infarction have frequently similar clinical presentations and poses an important clinical challenge in the differential diagnosis. In both cases, the electrocardiographic ST-T changes and an increase in troponins can be noted. Differential diagnosis may be very challenging and requires invasive assessment of coronary arteries and other investigations especially cardiac magnetic resonance. Case Presentation: In this report, we report a rare case of acute myocarditis misdiagnosed to an acute myocardial infarction in a patient presented to the emergency department for an acute onset of chest pain with ST-segment elevation on electrocardiogram for which he received urgent fibrinolysis. The confirmation of acute myocarditis was confirmed posteriori after a normal coronary angiogram using cardiac Magnetic Resonance Imaging cMRI. Conclusions: Clinical signs as long with Electrocardiogram may mimick a ST elevation myocardial infarction in the presence of an authentic acute myocarditis,Hence, cardiac magnetic resonance could present an intersting tools to make the difference even in acute phase.

Acute Cardiac Care

Current applications of cardiac magnetic resonance offer a wide spectrum of indications in the setting of acute cardiac care. In particular, cardiac magnetic resonance is helpful for the differential diagnosis of chest pain by the detection of ischaemia, myocardial stunning, myocarditis, and pericarditis. Also, Takotsubo cardiomyopathy and acute aortic diseases can be evaluated by cardiac magnetic resonance and are important differential diagnoses in patients with acute chest pain. In patients with restricted windows for echocardiography, according to guidelines, cardiac magnetic resonance is the method of choice to evaluate complications of an acute myocardial infarction. In an acute myocardial infarction, cardiac magnetic resonance allows for a unique characterization of myocardial damage by quantifying necrosis, microvascular obstruction, oedema (i.e. area at risk), and haemorrhage. These features will help us to understand better the pathophysiological events during infarction and will also allow us to assess new treatment strategies in acute myocardial infarction. To which extent the information on tissue damage will guide patient management is not yet clear, and further research, e.g. in the setting of the European Cardiovascular MR registry, is ongoing to address this issue. Recent studies also demonstrated the possiblity to reduce costs in the management of acute coronary syndromes when cardiac magnetic resonance is integrated into the routine work-up. In the near future, applications of cardiac magnetic resonance will continue to expand in the acute cardiac care units, as manufacturers are now strongly focusing on this aspect of user-friendliness. Finally, in the next decade or so, magnetic resonance imaging of other nuclei, such as fluorine and carbon, might become a reality in clinics, which would allow for metabolic and targeted molecular imaging with excellent sensitivity and specificity.
