Apart from the clinical manifestations, which can range from mild chest pain, fatigue, and respiratory or digestive issues to full cardiogenic shock in fulminant myocarditis [3], paraclinical investigations such as blood tests (biological inflammatory syndrome and cardiac markers such as CK, CK-MB, troponin, and NT-proBNP), electrocardiography, and echocardiography can be useful in raising the suspicion of acute myocarditis [24]. This evidence concerns the gene NPPB and myocarditis.
