Fondaparinux Sodium for Anticoagulant Therapy After Primary Percutaneous Coronary Intervention: A Single-Center Randomized Trial in China

Abstract

Abstract: In this study, we investigated the safety and efficacy of fondaparinux sodium in postpercutaneous coronary intervention (PCI) anticoagulation therapy for patients with ST-segment elevation myocardial infarction. There are a total of 200 patients with ST segment elevation myocardial infarction underwent PCI and anticoagulation therapy. They were randomly split into experimental (n = 108) and control groups (n = 92). The experimental group received postoperative fondaparinux sodium (2.5 mg q.d), while the control group received enoxaparin (4000 IU q12 h). We did not use a loading dose for enoxaparin. Bleeding incidence and major adverse cardiovascular/cerebrovascular events were monitored during hospitalization, and at 1, 3, and 6 months postsurgery. The primary end points, including bleeding, mortality, and myocardial infarction during hospitalization, were not significantly different between the 2 groups. For secondary end points, the incidence of combined end point events at 1 month, 3 months, and 6 months after surgery in the experimental group was lower than in the control group (P < 0.05). According to Cox regression analysis, the risk of bleeding in the experimental group was significantly lower than that in the control group [hazard ratios: 0.506, 95% confidence interval (CI): 0.284–0.900] (P = 0.020). The risk of mortality in the experimental group was significantly lower than in the control group (hazard ratio: 0.188, 95% CI: 0.040–0.889) (P = 0.035). In summary, perioperative use of fondaparinux sodium during PCI in patients with STEMI in this study was associated with a lower risk of bleeding and death compared with enoxaparin use in the absence of loading dose.
