Sepsis is frequently complicated by the release of cardiac troponin, but the clinical significance of this myocardial injury remains unclear. We studied the associations between troponin release during sepsis and 1-year outcomes.
We enrolled consecutive patients with sepsis in 2 Dutch intensive care units between 2011 and 2013. Subjects with a clinically apparent cause of troponin release were excluded. High-sensitivity cardiac troponin I (hs-cTnI) concentration in plasma was measured daily during the first 4 intensive care unit days, and multivariable Cox regression analysis was used to model its association with 1-year mortality while adjusting for confounding. In addition, we studied cardiovascular morbidity occurring during the first year after hospital discharge. Among 1258 patients presenting with sepsis, 1124 (89%) were eligible for study inclusion. Hs-cTnI concentrations were elevated in 673 (60%) subjects on day 1, and 755 (67%) ever had elevated levels in the first 4 days. Cox regression analysis revealed that high hs-cTnI concentrations were associated with increased death rates during the first 14 days (adjusted hazard ratio, 1.72; 95% confidence interval, 1.14-2.59 and hazard ratio, 1.70; 95% confidence interval, 1.10-2.62 for hs-cTnI concentrations of 100-500 and >500 ng/L, respectively) but not thereafter. Furthermore, elevated hs-cTnI levels were associated with the development of cardiovascular disease among 200 hospital survivors who were analyzed for this end point (adjusted subdistribution hazard ratio, 1.25; 95% confidence interval, 1.04-1.50).
Myocardial injury occurs in the majority of patients with sepsis and is independently associated with early-but not late-mortality, as well as postdischarge cardiovascular morbidity.
脓毒症常并发心肌肌钙蛋白释放,但这种心肌损伤的临床意义仍不明确。我们研究了脓毒症期间肌钙蛋白释放与1年预后之间的关联。
2011年至2013年期间,我们在荷兰的2个重症监护病房纳入了连续的脓毒症患者。排除有明显肌钙蛋白释放临床病因的受试者。在重症监护病房的前4天每天测量血浆中的高敏心肌肌钙蛋白I(hs-cTnI)浓度,并采用多变量Cox回归分析对其与1年死亡率的关联进行建模,同时调整混杂因素。此外,我们研究了出院后第一年发生的心血管疾病发病率。在1258例脓毒症患者中,1124例(89%)符合研究纳入标准。第1天,673例(60%)受试者的hs-cTnI浓度升高,755例(67%)在最初4天内曾有浓度升高。Cox回归分析显示,高hs-cTnI浓度与前14天内死亡率增加相关(调整后的风险比,1.72;95%置信区间,1.14 - 2.59;hs-cTnI浓度分别为100 - 500和>500 ng/L时的风险比,1.70;95%置信区间,1.10 - 2.62),但此后无相关性。此外,在针对这一终点进行分析的200例医院幸存者中,hs-cTnI水平升高与心血管疾病的发生相关(调整后的亚分布风险比,1.25;95%置信区间,1.04 - 1.50)。
大多数脓毒症患者会发生心肌损伤,且与早期而非晚期死亡率以及出院后心血管疾病发病率独立相关。
