Alveolar Hemorrhage Following Thrombolytic Therapy for Acute Myocardial Infarction: Two Case Reports and Literature Review.

Abstract

Alveolar hemorrhage (AH) is a heterogeneous clinical syndrome with a high mortality rate, characterized by extensive bleeding into the alveolar spaces. AH secondary to systemic thrombolysis treatment in the setting of acute myocardial infarction is an uncommon complication, but potentially fatal and can lead to acute respiratory failure. This entity is rarely reported in the literature. We report two cases of acute AH after intravenous thrombolysis for acute myocardial infarction, which could contribute to the literature on the subject, and discuss the risk factors as well as the clinical and radiological findings supporting the diagnosis. We overview also the rare previous published case reports in this context, and we contrast our findings with those reported in the literature.
