Официальное название
Non-Steroidal Anti-Inflammatory Drugs Versus Conventional Treatment in Acute Myocarditis (INFLAMA Trial)
Обзор
Prospective, randomized, multicenter, open-label clinical trial to evaluate the safety and efficacy of a 3-week ibuprofen tapering regimen compared to conventional analgesic treatment (acetaminophen) in patients with acute myocarditis and left ventricular ejection fraction ≥50%. The objective is to assess the reduction in late gadolinium enhancement on cardiac magnetic resonance imaging at 6-month follow-up.
Подробное описание
The treatment for patients with uncomplicated myocarditis (left ventricular ejection fraction \>50% without heart failure) is not currently well defined. Analgesic drugs are commonly used to manage pain. The use of nonsteroidal anti-inflammatory drugs (NSAIDs) among analgesics is controversial due to potential harmful effects observed in animal models. However, NSAIDs are the standard treatment for pericarditis, even when it is associated with mild myocardial involvement. In patients with acute myocarditis and normal left ventricular ejection fraction, observational studies have suggested that NSAIDs may have a beneficial effect in reducing late gadolinium enhancement (LGE) measured in cardiac magnetic resonance (CMR), an important prognostic marker in this population.
We plan to conduct a prospective, randomized, multicenter, open-label clinical trial to evaluate the safety and efficacy of NSAIDs versus conventional analgesic treatment in patients with uncomplicated acute myocarditis and left ventricular ejection fraction ≥50%.
Approximately 150 patients will be randomized 1:1 to NSAID treatment (ibuprofen tapering schedule during 3 weeks) or conventional treatment (acetaminophen or metamizole in case of allergy until pain resolution) during hospital admission. Patients will be followed for a 12-month period. Baseline CMR will be performed at initial hospitalization for acute myocarditis and at 3 and 6 months.
The primary objective is to assess the utility of ibuprofen versus conventional treatment with analgesics in acute myocarditis with preserved LVEF, in terms of reducing LGE on CMR at 6-month follow-up compared to baseline.
