Long-term Anticoagulant Therapy after Myocardial Infarction in Women

Abstract

A multicentre trial from five medical departments in Oslo has been carried out to determine the value in women patients of one year's long-term anticoagulant therapy. Follow-up long-term laboratory control and anticoagulant dosage were performed at one centre (the Rikshospitalet). One hundred and fifty-nine patients were assigned randomly into two similar well-matched groups (control and treatment). Dosage was controlled by Thrombotest, aiming at 10-20% levels, and 50% of the tests were less than 14%. Compared with the control group, the treatment group showed a significant reduction in mortality and in reinfarction rate. No serious bleeding complications occurred. It is concluded that women benefit as much as men from long-term anticoagulant therapy. © 1968, British Medical Journal Publishing Group. All rights reserved.
