Acute coronary syndrome with normal coronary arteries in coronary angiography is an important issue in modern cardiology. The aim of this study is to evaluate the usefulness of cardiac magnetic resonance imaging in patients with elevated values of markers of myocardial infarct and unobstructed coronary arteries in coronary angiography imaging.

Study group consisted of eleven patients with elevated troponin values and completely normal arteries in coronary angiography. Four patients had upper respiratory tract infections during previous two weeks. CMR study was performed for 10 days from cardiac episode using a 1.5 T scanner with a dedicated cardiac coil before and after administration of contrast media include assessing left ventricular ejection fraction, the presence of edema or delayed enhancement. Segments of the left ventricle was divided according to the AHA guidelines.

Cardiovascular magnetic resonance imaging revealed myocarditis features in 6 (54.5%) patients, two patients - the characteristics of transmural scar and three patients had normal results. Positive correlation was observed beetween ischemic changes and values of troponin and CK-MB. In the group of patients with myocarditis features mean LVEF was 56.7%, swelling was detected in 2 patients and delayed contrast enhancement in 5 patients. The results were compared with echocardiographic study.

CMR study is a useful diagnostic method in modern cardiovascular radiology. It provides valuable information especially in patients with unexplained cause of cardiac events and can be done at an early period after the stabilization of the clinical condition of the patient.

Early CMR is valuable in the evaluation of the differential diagnoses and to exclude myocardial abnormalities in patients with uncertain aetiology.
