摘要：

Although low molecular weight heparins (LMWH) have been extensively investigated for the prophylaxis and treatment of venous thromboembolism in surgical environments, few data in acute myocardial infarction are available in the literature. In this study two dosages of a new LMWH, Parnaparin, and unfractionated heparin (UF) were investigated in 50 pts with acute myocardial infarction. 20 pts received UF (15.000 units, three subcutaneous injections, Group 1), 20 pts received Parnaparin (6.400 units, single injection, Group 2) and 10 pts received a higher dose of Parnaparin (12.800 units, single injection, Group 3). Similar fibrinopeptide A (FpA) levels were observed in Group 1 and Group 2. In Group 3 the dosage of Parnaparin resulted in a significant prolongation of the APTT and in lower FpA levels. Fibrin formation was decreased by Parnaparin in a concentration-dependent way, according to both the anti-Xa activity and the APTT ratio. Parnaparin did not result in a significant increase in free fatty acid concentration, in comparison with UF. Thus, Parnaparin may offer the advantage of a single subcutaneous injection in patients with acute myocardial infarction.
