Abstract
Although the frequency of myocarditis in the general population is very difficult to accurately determine due to the large number of asymptomatic cases, the incidence of this disease is increasing significantly due to better defined criteria for diagnosis and the development of modern diagnostic method. The multitude of different etiological factors, the diversity of the clinical picture and the variability of the diagnostic findings make this disease often demanding both for the selection of the diagnostic modality and for the proper therapeutic approach. The previously known most common viral etiology of this disease is today overshadowed by new findings based on immune-mediated processes, associated diseases that in their natural course can lead to myocardial involvement, but also the iatrogenic cause of myocarditis due to use of immune checkpoint inhibitors in the treatment of cancer patients. Suspecting that a patient with polymorphic and non-specific clinical signs and symptoms, changes in ECG and echocardiography has myocarditis is the starting point in the diagnostic algorithm. Cardio magnetic resonance imaging is non-invasive diagnostic gold standard for diagnosis and clinical follow-up of thses patients. Endomyocardial biopsy as an invasive method is the diagnostic choice in life-threatening patients with suspicion of fulminant myocarditis where the diagnosis has not yet established or there is no adequate response to the applied therapeutic regimen. The treatment of myocarditis is increasingly demanding and includes conservative methods of treating heart failure, immunomodulatory and immunospressive therapy, methods of mechanical circulatory support and heart transplantation. The goal of developing new diagnostic and therapeutic methods is to reduce mortality from this complex disease, which is still high.
