Objective: Acute pulmonary thromboembolism (PTE) is a serious high mortality pulmonary vascular disease whose effective treatment decreases morbidity and mortality. To determine if low-molecular-weight-heparin (LMWH) is clinically as efficient and safe as unfractionated heparin (UH) in patients with diagnosis of acute non-massive PTE, our study compares the efficacy, adverse effects and costs of LMWH and UH. Methods: One hundred and fourteen patients with non-massive acute PTE were randomly divided into LMWH (nadroparin calcium) and UH groups. Oxygenation index, D-dimer, fibrinogen (FG), lung ventilation/perfusion (V/Q) scan and computed tomography pulmonary angiography (CTPA) were observed before anticoagulation and on day 14 after anticoagulation. Results: In both groups, the ABG (arterial blood gas) analysis showed PaO2 and PaCO2 were elevated, P(A-a)O2 was decreased and oxygenation index (PaO2/FIO2) was elevated, D-dimer and fibrinogen were decreased, lung V/Q and CTPA showed embolized segments reduced (P<0.05). Hemorrhage and thrombocytopenia occurred in 3.5% of the LMWH group. Hemorrhage occurred in 5.3% and thrombocytopenia occurred in 7.0% of the UH group. The average cost in the LMWH group was RMB 1218.60 Yuan and RMB 1541.40 Yuan in the UH group. Conclusion: LMWH and UH are equally effective for treatment of non-massive acute PTE, but LMWH may have a lower prevalence of complications and is less expensive.
