胰岛素对急性ST段抬高型心肌梗死伴应激性高血糖患者近期预后的影响

目的 探讨胰岛素治疗对急性ST段抬高型心肌梗死(ASTEMI)伴应激性高血糖患者近期预后的影响.方法 将128例ASTEMI伴应激性高血糖患者随机分为治疗组和对照组各64例,均给予抗凝、抗血小板、他汀类、β受体阻滞剂、硝酸酯类药物和血管紧张素转化酶抑制剂(ACEI)或血管紧张素受体拮抗剂(ARB)治疗,治疗组在此基础上给予50 U胰岛素(选用诺和灵R)加入50 ml生理盐水中静脉泵入.分别在治疗前和治疗后第7天抽取静脉血,测定空腹血糖、超敏C反应蛋白(hs-CRP),并比较两组的近期预后情况.结果 治疗组治疗后空腹血糖较治疗前显著下降(5.4±0.8)、(11.6±2.3)mmol/L,t =13.97,P＜0.01],而对照组无明显变化(10.7±2.1)、(11.2±2.7) mmol/L,t =1.79,P＞0.05].两组患者的hs-CRP均较治疗前显著下降治疗组(6.2±1.5)、(12.8±2.4) mg/L,t=14.26;对照组(8.7±1.8)、(13.1±2.6)mg/L,t=10.97,P均＜0.01].两组治疗后空腹血糖、hs-CRP比较,差异均有统计学意义(t值分别为-9.78、-0.37,P均＜0.01).随访3个月,治疗组患者主要不良心脏事件发生率低于对照组 12.50％ (8/64)与34.38％ (22/64),X2=5.02,P＜0.05].结论 胰岛素治疗能改善ASTEMI伴应激性高血糖患者的近期预后.

The influence of insulin therapy on the short-term prognosis of patients with acute ST-elevation myocardial infarction complicated with hyperglycaemia

Objective To observe the influence of insulin therapy on the short-term prognosis of patients with acute ST-elevation myocardial infarction (ASTEMI) complicated with hyperglycaemia.Methods A total of 128 patients with ASTEMI complicated with hyperglycaemia were randomized into 2 groups:treatment group and control group.There were 64 patients(50.0％ )in the treatment group and 64 patients(50.0％ ) in the control group.All of the patients were given anticoagulants,antiplatelet drugs,statins,beta-receptor blockers,nitrates and angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blocker (ARB) Moreover,the patients in the treatment group were given extra 50 U insulin ( Novolin R) in 50 ml saline by venous infusion.In the treatment group,Venous blood samples were obtained before and 7 days after treatment to determine the fasting blood glucose and hs-CRP in serum; the levels of fasting blood glucose and hs-CRP and short-term prognosis were compared between the 2 groups.Results The levels of fasting blood glucose in the treatment group were decreased significantly after treatment ( 5.4 ± 0.8 ] mmol/L vs 11.6 ± 2.3 ] mmol/L,P ＜0.01),but there was no significant change in the control group( 10.7 ± 2.1 ] mmol/L vs 11.2 ± 2.7]mmol/L,P ＞ 0.05 ).The levels of hs-CRP in both groups were decreased significantly after treatment (P ＜0.05),but it was much more obvious in the treatment group( 6.2 ± 1.5 ] mg/L vs 8.7 ± 1.8 ] mg/L,P ＜0.05).The incidence of major adverse cardiac events(MACE) during a 3 months′ follow-up in the treatment group was significantly lower than that in the control group ( 12.50％ vs 34.38％,P ＜ 0.05 ).Conclusion Insulin therapy can improve the short-term prognosis in patients with ASTEMI complicated with hyperglycaemia.
