Elevated levels of troponin-I (TnI) are common in out-of-hospital cardiac arrest (OHCA) patients. However, studies evaluating the prognostic value of TnI clearance in OHCA patients are lacking. We aimed to examine how TnI clearance (TnI-C) differed according to the neurological outcome group and mortality group at 6 months.
This retrospective observational study involved adults ( 18 years) who were treated for an OHCA between January 2019 and December 2022. The TnI-Cs were calculated for days 1 to 2 (TnI-C1st) and 2 to 3 (TnI-C2nd) after the return of spontaneous circulation (ROSC). The primary outcome was a poor neurological outcome at 6 months, defined by cerebral performance categories 3, 4, and 5. The secondary outcome was 6-month mortality.
A total of 227 patients were included. A poor neurological outcome and mortality at 6-months were reported in 150 (66.1%) and 118 (52.0%) patients, respectively. The TnI-C1st was significantly lower in patients with a poor outcome compared with good outcome patients (neurological outcome at 6 months, 54.4% vs. 42.3%; 6-month mortality, 52.1% vs. 42.7%, respectively). In the multivariable analyses, a TnI-C1st 50% was associated with a poor neurological outcome (odds ratio [OR] 2.078, 95% confidence interval [CI] 1.080-3.995, = 0.028) and mortality (OR 2.131, 95% CI 1.114-4.078, = 0.022) at 6 months.
After ROSC, TnI-C1st 50% was associated with a poor neurological outcome and mortality at 6 months in OHCA patients.
肌钙蛋白I（TnI）水平升高在院外心脏骤停（OHCA）患者中很常见。然而，评估TnI清除率对OHCA患者预后价值的研究尚缺乏。我们旨在研究6个月时TnI清除率（TnI-C）在神经学预后组和死亡率组之间如何不同。
这项回顾性观察性研究纳入了2019年1月至2022年12月期间接受OHCA治疗的成年人（≥18岁）。计算自主循环恢复（ROSC）后第1至2天（TnI-C1st）和第2至3天（TnI-C2nd）的TnI-C。主要结局是6个月时神经学预后不良，由脑功能分类3、4和5定义。次要结局是6个月死亡率。
共纳入227例患者。分别有150例（66.1%）和118例（52.0%）患者报告了6个月时神经学预后不良和死亡。预后不良患者的TnI-C1st显著低于预后良好患者（6个月时神经学预后，分别为54.4%对42.3%；6个月死亡率，分别为52.1%对42.7%）。在多变量分析中，TnI-C1st<50%与6个月时神经学预后不良（比值比[OR]2.078，95%置信区间[CI]1.080-3.995，P = 0.028）和死亡率（OR 2.131，95%CI 1.114-4.078，P = 0.022）相关。
ROSC后，TnI-C1st<50%与OHCA患者6个月时神经学预后不良和死亡率相关。
