Cardiac sarcoidosis: difficulties and possibilities of differential diagnosis for acute coronary syndrome without ST segment elevation in real clinical practice

Here we present a clinical case of cardiac sarcoidosis. The article discusses the difficulties of differential diagnosis in patients emergently hospitalized in the cardiology department with recurrent chest pain, no changes in the electrocardiogram (ECG), and a presumptive diagnosis of acute coronary syndrome without ST segment elevation (NSTE-ACS). A careful history taking, invasive coronary angiography, and contrast-enhanced (gadolinium-based contrast media) cardiac magnetic resonance imaging (CMR) contributed to the correct diagnostic decision in search for and identification of cardiac sarcoidosis in the patient.
