Low-Molecular-Weight Heparins in Acute Unstable Coronary Artery Disease – An Update
- Additional Document Info

Low-molecular-weight heparins (LMWHs) have been rigorously evaluated in the management of acute coronary ischaemia. The results of clinical trials suggest that the LMWHs (enoxaparin, dalteparin and nadroparin) are effective and safe in the treatment of unstable angina and non-Q-wave myocardial infarction. Two studies have shown enoxaparin to be more effective than unfractionated heparin in this setting. Furthermore, the pharmacologic and pharmacokinetic characteristics of LMWHs result in them having practical and economic advantages. Data on the benefits of long-term therapy with LMWHs are conflicting.
