Clinica Chimica Acta:Elecsys®肌钙蛋白T Gen 5分析性能评价

2019-10-17 gladiator MedSci原创

本研究报告了本研究报告了Elecsys®肌钙蛋白T Gen 5 STAT (TnT Gen 5 STAT;罗氏诊断)的分析性能。

本研究报告了Elecsys®肌钙蛋白T Gen 5 STAT (TnT Gen 5 STAT;罗氏诊断)的分析性能。锂肝素血浆样品的极限值/范围一般根据临床和实验室标准协会(CLSI) EP17-A2测定。使用cobas e 411/cobas e 601分析仪上的锂肝素等离子体/质量控制样品,按CLSI EP05-A2进行精密度评估;且每天重复运行2次连续21 天(n=84)。并测试了与其他肌钙蛋白形式的交叉反应性和内源性物质/药物的干扰;无交叉反应的恢复标准应在±10%以内。

研究结果显示,重复性/中间精度的变异系数(CV)为0.7-5.6/ 1.4-10.3%(cobas e 411;平均心肌肌钙蛋白T [cTnT]7.3-9341ng / L)和0.7-3.0/ 1.5-6.4 %(cobas e 601;平均cTnT7.4–9455 ng / L)。 与骨骼肌肌钙蛋白T≤10,000 ng / L),骨骼肌肌钙蛋白I≤100,000 ng / L),心肌肌钙蛋白I≤10,000 ng / L)或人肌钙蛋白C≤80,000 ng)无交叉反应/ L)。 对生物素(≤20µng / mL)或34种药物未观察到干扰。

TnT Gen 5 STAT测定法显示在第99个百分位数上限时CV <10%,符合高灵敏度肌钙蛋白测定法的精确度要求(心肌梗死的第四通用定义)。

JAHA:TAVR术后肌钙蛋白水平与远期死亡率相关

管主动脉瓣置换术(TAVR)后的肌钙蛋白往往会升高,但其预后意义尚不清楚。本研究的目的旨在探究TAVR术后与远期死亡率相关的肌钙蛋白阈值。本研究纳入了510名接受TAVR治疗的患者,平均随访时间为2.6±1.3年,排除经心尖TAVR后,分析结果显示,肌钙蛋白升高≥3倍正常高值是预测远期死亡率的最佳阈值(HR:1.57, CI 1.04–2.38,P=0.03)。另外,导致非血运重建型冠心病(CAD

JAMA Cardiol:高敏感心肌肌钙蛋白测定时代的心肌损伤

传统上,肌钙蛋白浓度升高与心肌梗死同义。但随着肌钙蛋白检测技术的进步,现在更常见的是没有明显心肌缺血的浓度升高;这被称为心肌损伤。因为没有心肌缺血,医生可能会错误地消除疑虑;然而,最近的证据表明,心肌损伤与更有害的结果有关。因此,本文回顾了心肌损伤的定义,流行病学,鉴别诊断,诊断评估和管理。

Circulation:运动后肌钙蛋白I升高提示未来死亡和心血管事件风险高

心肌肌钙蛋白血浓度高于99个百分位是诊断急性心肌损伤和梗死的关键指标。但肌钙蛋白浓度即使低于99百分位点对于患者和一般人群也具有预测预后不良的价值。在耐力运动后常见肌钙蛋白浓度升高,但其临床意义尚不明确。研究人员对725位受试者(61[54-69]岁)行走30-55km前后心肌肌钙蛋白I的水平进行检测,来研究长距离步行者运动后肌钙蛋白I浓度与临床结果之间的关系。受试者行走了8.3(7.9-9.3)

肌钙蛋白升高绝不只是心梗!

高敏心肌肌钙蛋白(hs-cTn)目前被公认为心肌梗死诊断中最重要的标志物。然而,很多临床情境下hs-cTn的表达量也会升高,在这些情境中,hs-cTn的升高是否对诊断、预后评估和治疗有指导意义?
