Abstract
Clinical efficacy of trimetazidine and plasmin combined with alprostadil in the treatment of lower extremity arteriosclerosis obliterans was investigated. A retrospective analysis was performed on 132 patients with lower extremity arteriosclerosis obliterans treated in Yantai Yuhuangding Hospital from March 2015 to August 2017. Among them, 68 patients were treated with trimetazidine combined with alprostadil (group A), and 64 patients were treated with plasmin combined with alprostadil (group B). Patients were administered 2 courses of treatment and observed with regard to therapeutic effects, changes in blood flow perfusion indicators (vascular peak velocity and blood flow) of the superficial femoral artery, posterior tibial artery and dorsalis pedis artery, in endothelial function, in left ankle brachial index, in pain-free walking distance and in maximum walking distance. After treatment, the vascular peak velocity of group B patients was lower than that in group A (P<0.05), but the blood flow was higher than that in group A (P<0.05). After treatment, endothelial esterase, high-sensitivity C-reactive protein and circulating endothelial cell count levels after treatment were lower than those before treatment (P<0.05), but nitric oxide level was higher than that before treatment (P<0.05). After treatment, the left ankle brachial index was lower in group A of patients than that in group B (P<0.05). After treatment, the maximum walking distance was significantly higher in group A patients than that in group B (P<0.05). After treatment, the pain-free walking distance and maximum walking distance of the two groups of patients were higher than those before treatment (P<0.05). Both trimetazidine and plasmin combined with alprostadil can effectively treat lower extremity arteriosclerosis obliterans. The former is better than the latter in improving exercise capacity, but the latter is better than the former in improving blood flow perfusion in patients.
