Hemopericardium and cardiac tamponade after thrombolysis for acute ischemic stroke.

Hemorrhage is the major complication of IV recombinant tissue plasminogen activator (rt-PA) treatment for stroke. We report three patients with mild or indistinct cardiac symptoms prior to thrombolysis in whom hemodynamically significant cardiac tamponade occurred after treatment with rt-PA. Acute ischemic stroke patients may have undetected myocardial or pericardial disease that may pose a risk for hemopericardium and life-threatening tamponade after treatment with rt-PA.
