摘要 目的探讨心肌肌钙蛋白Ⅰ(CTnI)、肌红蛋白(Myo)和肌酸激酶同功酶(CK-MB)联合检测对急性心肌梗死(AMI)早期诊断的价值.方法采用美国博适-Triage干式快速定量心肌梗死/心衰诊断仪,对急诊收治入院的82例急性胸痛病人,选择0~4h,5~8h,9~12h,13~16h,采血动态测定其含量.结果 55例AMI组其0~4h,5~8h,9~12h,13~16h,结果较非AMI患者明显升高(P<0.05),两组Myo、CK-MB结果,0~4h结果无明显差异(P>0.05),而5~8h,9~12h,13~16h两组间结果有明显差异(P<0.05),三项联合检测0~4h对AMI诊断的敏感性和特异性分别是76.4%和74.5%,9~12h,13~16h的敏感性和特异性均为98.2%.结论用荧光免疫干片法联合测定急性胸痛患者血中CTnI、Myo、CK-MB浓度,快速、简便,测得结果特异、敏感,有助于床边快速诊断和鉴别诊断,及时准确地提供溶栓治疗的依据,以降低死亡率.
