Another study investigating the clinical and electrocardiographic characteristics of patients diagnosed with fulminant myocarditis categorized the patients into three categories, including those with fulminant myocarditis, those with acute myocarditis, and those with acute pericarditis, and the NT-proBNP levels in the group with fulminant myocarditis were significantly higher than those of the other groups [24]. The gene discussed is NPPB; the disease is myocarditis.
