Article abstract What is the risk of thrombolysis in patients with acute stroke who might recover without treatment? In the National Institute of Neurological Disorders and Stroke rt-PA for Acute Stroke Trial, 2.6% of patients taking placebo showed spontaneous 24-hour recovery, compared to 11.5% of recombinant tissue-type plasminogen activator (rt-PA)treated patients (p < 0.001). There were no symptomatic ICH in the patients taking placebo; one hypertensive, rt-PAtreated patient hemorrhaged. Assuming the National Institute of Neurological Disorders and Stroke protocol is followed rigorously, patients with acute stroke rarely recover spontaneously and the thrombolytic risk is low.
