Comparison of Low-Molecular-Weight Heparin With Unfractionated Heparin Acutely and With Placebo for 6 Weeks in the Management of Unstable Coronary Artery Disease

Our results add to previous evidence suggesting that the low-molecular-weight heparin dalteparin administered by twice-daily subcutaneous injection may be an alternative to unfractionated heparin in the acute treatment of unstable angina or non-Q-wave myocardial infarction. Prolonged treatment with dalteparin at a lower once-daily dose in our study did not confer any additional benefit over aspirin (75 to 165 mg) alone.
