Key result
Elevated NT-proBNP, reduced LVEF, prolonged PR, and widened QRS are linked to higher fulminant myocarditis risk.
Prolonged PR interval, widened QRS complex, elevated NT-proBNP, and reduced LVEF at admission can help identify adult patients with acute viral myocarditis at risk for a fulminant course.
May aid risk stratification in acute myocarditis; hypothesis-generating and requires prospective validation before guiding care.
The risk of a fulminant course of acute myocarditis is higher in patients with elevated NT-proBNP, reduced left ventricular ejection fraction, and conduction disturbances at admission. Prolonged PR interval and widened QRS complex on admission are independent risk factors for developing fulminant myocarditis in adult patients with acute viral myocarditis.
