目的:研究床边快速CTnI、Myo和CK-MB三项联合检测对急性心肌梗死早期诊断的临床应用价值。方法:选择我院2016年1月-2016年11月因急性胸痛住院病人50例,同时做床旁心肌坏死标记物检测和在检验科进行的心肌酶谱检测。对收住院的患者进行追踪动态观察患者的症状体征、CTnI、Myo和CK-MB三项酶学变化、心电图改变、彩色超声检查做出明确诊断。比较床边快速三项酶学联合检测与同期结合心电图、心脏彩超检查结果对心肌挫伤急性心肌梗死的敏感性和特异性。结果三项联合检测比心肌酶谱联合心电图更加快捷、准确。结论床旁快速联合测定CTnI、Myo和CK-MB能够准确迅速诊断出AMI,可以提高对急性心肌梗死的早期诊断率,为溶栓治疗以及冠脉介入治疗提供依据并赢得宝贵的时间。
Objective: To study the clinical value of three bedside fast CTnI, Myo and CK-MB combined tests in the early diagnosis of acute myocardial infarction. Methods: Fifty hospitalized patients with acute chest pain were selected from January 2016 to November 2016 in our hospital. At the same time, myocardial markers of bedside myocardial necrosis and myocardial enzymes were detected in the laboratory. Patients admitted to the hospital to track the dynamic observation of patients with symptoms and signs, CTnI, Myo and CK-MB three enzymatic changes, ECG changes, color ultrasound to make a clear diagnosis. Compare bedside rapid three enzymology joint detection with the same period combined with electrocardiogram, echocardiography examination results myocardial infarction with acute myocardial infarction sensitivity and specificity. Results three joint detection of myocardial enzymes compared with ECG more quickly and accurately. Conclusion The rapid combination bedside CTnI, Myo and CK-MB can accurately and rapidly diagnose AMI, which can improve the early diagnosis rate of acute myocardial infarction, provide basis for thrombolytic therapy and coronary intervention, and win valuable time.
