目的:探讨高敏肌钙蛋白-T(hs-cTnT)用于老年急性胸痛患者急性心肌梗死(AMI)诊断的阈值及性能。方法:选取佛山市南海区红卫医院及佛山市第五人医院在2014年4月至2016年1月就诊的48例老年(65岁及以上)急性胸痛患者(观察组),与同期48例65岁以下的急性胸痛患者(对照组),所有患者均对其hs-cTnT水平进行检测,对两组患者中AMI患者及非AMI患者的hs-cTnT水平进行观察比较,并对hs-cTnT诊断AMI患者的最佳阈值及性能等进行分析。结果:观察组中AMI患者与非AMI患者的hs-cTnT水平均明显高于对照组,差异具有统计学意义(P<0.05),观察组AIM诊断的阈值为(32.0±2.5)ng/L,对照组的阈值为(14.2±1.8)ng/L,组间比较,观察组也明显高于对照组,差异具有统计学意义(P<0.05)。结论:老年急性胸痛患者AMI的诊断中,其诊断最佳阈值为(32.0±2.5)ng/L,且hs-cTnT水平与患者的年龄表现为正相关性。
Objective: To investigate the threshold and performance of hs-cTnT in the diagnosis of acute myocardial infarction (AMI) in elderly patients with acute chest pain. Methods: A total of 48 elderly patients (aged 65 years and older) with acute chest pain (observation group) from Hongwei Hospital of Nanhai District, Foshan City and Foshan Fifth People Hospital from April 2014 to January 2016 were enrolled. Compared with 48 cases Patients with acute chest pain under 65 years old (control group), all patients were detected hs-cTnT levels, the two groups of patients with AMI and non-AMI patients hs-cTnT levels were observed and compared hs-cTnT diagnosis AMI patients with the best threshold and performance analysis. Results: The hs-cTnT levels in AMI patients and non-AMI patients in observation group were significantly higher than those in control group (P <0.05). The threshold of AIM in observation group was (32.0 ± 2.5) ng / L, The threshold of the control group was (14.2 ± 1.8) ng / L, the observation group was also significantly higher than the control group, the difference was statistically significant (P <0.05). Conclusion: The best threshold for diagnosis of AMI in elderly patients with acute chest pain is (32.0 ± 2.5) ng / L, and the level of hs-cTnT is positively correlated with the age of patients.
