Usefulness of heparin in initial management of patients with recent transient ischemic attacks
S. F. Putman and H. P. Adams Jr
We evaluated the efficacy of short-term intravenous heparin therapy in 74
patients with recent transient ischemic attacks (TIAs). The patients were
treated after hospitalization until operation or long-term medical
treatment was instituted. Heparin was given in a continuous infusion to
maintain an activated partial thromboplastin time of 1 1/2 to 2 1/2 times
control values. During the treatment period, 12 patients (16.2%) had
recurrent TIAs and five (6.8%) had cerebral infarction. Bleeding
complications occurred in nine patients (12.2%). In this limited series,
heparin did not prevent recurrent TIAs or cerebral infarction among
high-risk patients with recent TIAs.
