The exercise ECG stress test (EST) is still the first step of work-up in intermediate risk patients in many clinical scenarios. High-sensitive cardiac troponin T (hs-cTnT) elevation is related to future cardiovascular events in the general population and in patients with ischaemic heart disease. The relation between these 2 tests is not well described.
A total of 2780 participants from the Tel-Aviv Medical Center Inflammation Survey cohort (mean age 49 years, 79% men) were analysed. Multiple physiologic and metabolic parameters including hs-cTnT were collected. All participants completed an EST manually reviewed by a cardiologist.
A positive EST was documented in 224 subjects (8%). The majority (91%) of participants with hs-cTnT levels of 5-14 ng/L had a negative EST as well as 89.3% of subjects with levels >14 ng/L. The proportion of subjects with a positive EST and detectable hs-cTnT levels (>5 ng/L) was not significantly greater compared to those with a negative EST (53.1% vs 46.2%, respectively, P = .09).
Among subjects referred for EST as part of an annual health survey, we found no significant association between EST results to hs-cTnT detection.
在许多临床情况下，运动心电图应激试验（EST）仍然是中危患者的初步检查手段。高敏心肌肌钙蛋白 T（hs-cTnT）升高与普通人群和缺血性心脏病患者的未来心血管事件有关。这两种检测之间的关系尚未得到很好的描述。
对来自特拉维夫医疗中心炎症调查队列的 2780 名参与者（平均年龄 49 岁，79%为男性）进行了分析。收集了包括 hs-cTnT 在内的多种生理和代谢参数。所有参与者均完成了由心脏病专家手动审查的 EST。
224 名（8%）患者的 EST 结果为阳性。大多数（91%）hs-cTnT 水平为 5-14ng/L 的患者的 EST 为阴性，hs-cTnT 水平>14ng/L 的患者中也有 89.3%的 EST 为阴性。与 EST 阴性者相比，EST 阳性且 hs-cTnT 水平可检测（>5ng/L）的患者比例没有显著差异（分别为 53.1%和 46.2%，P=.09）。
在作为年度健康检查一部分而接受 EST 的患者中，我们发现 EST 结果与 hs-cTnT 检测之间没有显著关联。
