目的探讨心肌肌钙蛋白I(cTnI)诊断尿毒症合并急性心肌梗死的界限值。方法检测尿毒症及尿毒症合并心肌梗死患者cTnI含量,并与正常对照组比较。同时比较各组患者cTnI增高程度分层及相对百分比,计算不同cTnI浓度对尿毒症合并心肌梗死诊断的敏感性、特异性、阴性预测值、阳性预测值的影响。结果 3组cTnI含量比较有显著差异性(P均<0.01),cTnI>0.6ng/ml,尿毒症合并心肌梗死的敏感性为90%,特异性为99.7%。结论 cTnI>0.6ng/ml,敏感性及特异性均较高,可以作为诊断尿毒症合并心肌梗死患者的参考值。
Objective To investigate the value of cardiac troponin I (cTnI) in the diagnosis of uremia with acute myocardial infarction. Methods The levels of cTnI in patients with uremia and uremia complicated with myocardial infarction were measured and compared with those in normal controls. At the same time, the stratification and relative percentage of cTnI in each group were compared to calculate the sensitivity, specificity, negative predictive value and positive predictive value of different concentrations of cTnI in the diagnosis of uremia complicated with myocardial infarction. Results The cTnI levels in the three groups were significantly different (all P <0.01), cTnI> 0.6ng / ml. The sensitivity and specificity of uremia with myocardial infarction were 90% and 99.7% respectively. Conclusion cTnI> 0.6ng / ml, the sensitivity and specificity are high, and can be used as a reference value in diagnosing uremic patients with myocardial infarction.
