Diffuse alveolar hemorrhage following thrombolytic therapy for acute myocardial infarction.

We describe a 66-year-old patient with hemoptysis, a drop in hematocrit, hypoxemia and new bilateral alveolar infiltrates after receiving streptokinase for acute myocardial infarction. Markedly increased carbon monoxide diffusion capacity suggested a diagnosis of alveolar hemorrhage. Underlying conditions included congestive heart failure. The patient recovered uneventfully within 7 days of conservative treatment. Alveolar hemorrhage is a rare and often unrecognized life-threatening complication of thrombolytic therapy. Particular attention should be paid to the pulmonary status of patients with congestive heart failure scheduled to receive thrombolytic therapy. Copyright 2000 S. Karger AG, Basel
