Pulmonary haemorrhage following thrombolysis with streptokinase in myocardial infarction.

Pulmonary haemorrhage is a rare but a life-threatening complication of thrombolytic therapy in patients with acute ST-elevation myocardial infarction (MI). It usually presents with anaemia, massive haemoptysis, acute-onset respiratory distress and diffuse bilateral lung infiltrates on imaging. We hereby describe two patients, who had pulmonary haemorrhage following streptokinase therapy for acute MI. The first patient improved with conservative treatment, while the second patient died due to respiratory failure. Streptokinase, a fibrin non-specific agent, is a widely used thrombolytic in low-income and middle-income countries. Pulmonary haemorrhage should be suspected in patients who develop sudden respiratory compromise after receiving thrombolytics, especially streptokinase. The management issues related to this uncommon life-threatening complication have been discussed in this article.
