Abstract:Objective To investigate the effect of Beraprostine combined with Argatroban on nailfold microcirculation and walking distance in elderly patients with arteriosclerosis obliterans.Methods A total of 120 patients with arteriosclerosis obliterans who were admitted to the Department of Geriatrics of the First Affiliated Hospital of Hebei Northern University from July 2019 to July 2021 were selected and included in the study, and divided into an observation group and a control group according to the random number table method, with 60 cases in each. The patients in the control group were treated with Beraprost sodium tablets orally, and the patients in the observation group were treated with Argatroban injection on the basis of the control group. The treatment effect and adverse reactions of the two groups were compared. The difference of initial walking distance, absolute walking distance, loop shape score, blood flow pattern score, loop state score, total score, peak systolic blood flow velocity (PSV), ankle brachial index (ABI), C-reactive protein (CRP), monocyte chemokine-1 (MCP-1), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were compared between the two groups before and after treatment.Results The total effective rate of the observation group was 90.00%, which was significantly higher than that of the control group (65.00%) (P < 0.05). The difference of initial walking distance and absolute walking distance in the observation group before and after treatment was greater than that in the control group (P < 0.05). The difference of blood flow state integral, loop state integral, and total integral in the observation group before and after treatment was greater than that in the control group (P < 0.05). The difference of PSV and ABI in the observation group before and after treatment was greater than that in the control group (P < 0.05). The differences of CRP, MCP-1, IL-6, and TNF-α in the observation group before and after treatment were greater than those in the control group (P < 0.05). The total incidence of adverse reactions in the observation group and the control group were 20.00% and 16.67%, respectively, with no significant difference (P > 0.05).Conclusion The combination of Beraprostina and Argatroban in the treatment of elderly patients with arteriosclerosis obliterans can effectively increase the walking distance and improve nailfold microcirculation.
