RESUMO
Objective To investigate the effect of alprostadil in the treatment of interventional angiography in elderly patients with coronary heart disease after contrast nephropathy prevention.Methods From February 1,2014 to January 31,2017,60 elderly patients with coronary heart disease with interventional therapy in Yuncheng Central Hospital of Shanxi Province were divided into two groups,with 30 cases in each group.The control group received hydration therapy,the observation group was given alprostadil combined with hydration therapy.The biochemical index changes before surgery and three days after surgery and incidence of contrast nephropathy were compared between the two groups.Results Before surgery and three days after surgery,the tumor necrosis factor alpha,beta 2 microglobulin, urea and creatinine in the two groups were not changed significantly.Three days after surgery,24h urine protein, superoxide dismutase,glutathione peroxidase,interleukin －6 and C reactive protein levels in the two groups were increased,the increase amplitude of the observation group was smaller.Three days after surgery,the five indicators of the observation group were (185.54 ±86.47)mg,(2.01±1.32)mg/L,(6.18 ±2.13)g/L,(135.56 ±41.58)ng/L, (1.21±1.05 )mg/L,respectively,the differences were ststistically significant between the two groups (t ＝1.21, 1.24,1.50,1.26,1.22;P＝0.03,0.03,0.04,0.03,0.04).Three days after surgery,the creatinine clearance rate of the observation group was (98.67 ±21.56)mL/min,which was higher than that of the control group(t＝2.71,P＝0.01).The incidence rate of contrast induced nephropathy in the observation group (3.33%)was lower than that in the control group(χ2＝5.19,P＝0.02).Conclusion Alprostadil can effectively prevent contrast nephropathy in elderly patients with coronary heart disease after interventional therapy.
