Single Blind Randomized Controlled Trial to Assess the Safety and Efficacy of High Dose Pulse Intravenous Corticosteroid Therapy to Treat Patients With Complicated/Fulminant Acute Myocarditis
Niguarda Hospital
Summary
This is a phase III, multi-center international, single blind randomized controlled trial to test the efficacy of pulsed intravenous (IV) methylprednisolone versus standard therapy on top of maximal support in patients with Acute myocarditis (AM).
Description
Acute myocarditis (AM) is a common condition characterized by histological evidence of inflammatory infiltrates associated with myocyte necrosis of non-ischemic origin. Clinical presentation spans from indolent form to cardiogenic shock also called fulminant myocarditis (FM). Patients can be stratified on the basis of their clinical presentation: patients with left ventricular (LV) ejection fraction (EF)\<50% at first echocardiogram, and those with sustained ventricular arrhythmias, called complicated AM, have a worse prognosis compared with uncomplicated cases with preserved left ventricular…
