Thrombolytic-related complication in a case of misdiagnosed myocardial infarction.

The importance of early thrombolysis in acute myocardial infarction has been highlighted in several large trials. The clinical decision is often taken by physicians who need to take a rapid action with the risk of misdiagnosing non-coronary events that mimic myocardial infarction. Here we describe a case of acute pericarditis in a 37-year-old man whom received thrombolysis and developed a sudden hemorrhagic pericardial effusion that evolved rapidly into a cardiac tamponade. These errors leading to lethal thrombolysis complications have been surprisingly rare; but a correct diagnosis of aortic dissection or hemorrhagic pericarditis needs to be stressed because even after obtaining the correct diagnosis, the prolonged disturbance of hemostasis prevents a rapid therapy being instigated.
