Massive pulmonary haemorrhage complicating the treatment of acute coronary syndrome

Antiplatelet medications such as clopidogrel and tirofiban (glycoprotien IIb/IIIa inhibitors) are associated with a reduction in mortality and morbidity and are therefore recommended in the treatment of acute coronary syndromes. Massive pulmonary haemorrhage is a rare complication of both clopidogrel and tirofiban. Pulmonary haemorrhage may easily be mistaken for acute pulmonary oedema, a condition commonly seen in patients with acute coronary syndrome. Physicians need to be aware of this diagnostic dilemma because early treatment increases the chances of patient survival.
