Further experience with long-term anticoagulant therapy

The need for continuous administration of anticoagulants became apparent early in the clinical use of these drugs.* As a result of experience gained in the treatment of patients with rheumatic heart disease and recurrent embolization, we suggested in 1946 that these patients be maintained on anticoagulants.

Beaumont, of Paris, and others reported similar results. CLINICAL MATERIAL AND DOSAGE The total number of patients we have followed on
