众所周知,处于糖尿病前期者和糖尿病患者存在较高的心血管事件发生风险。然而,糖尿病前期和糖尿病与亚临床心肌损害发生间的关系尚不明确。方法与结果:应用高敏心肌肌钙蛋白T(highly sensitive cardiac troponin T,hs-cTnT)分析,测定社区动脉粥样硬化风险研究中9331例受试者两个时间点(间隔6年)的心肌肌钙蛋白T(cardiac troponin T,cTnT)水平,所有受试者为无糖尿病或处于糖尿病前期,或糖尿病不伴心血管疾病(包括心电图检测出来的无临床症状的心肌梗死)。研究人员在6年随访期间检测研究 It is well-known that there is a high risk of cardiovascular events in pre-diabetic and diabetic patients. However, the relationship between pre-diabetes and diabetes and subclinical myocardial damage is not yet known. Methods and Results: The cardiac muscle of two of 9331 subjects (6-year interval) in the study of atherosclerosis risk in the community was analyzed using highly sensitive cardiac troponin T (hs-cTnT) Cardiac troponin T (cTnT) levels. All subjects were non-diabetic or prediabetic, or were not associated with cardiovascular disease (including ECG-free myocardial infarction without clinical symptoms). Researchers tested during the 6-year follow-up study
