High-mobility group box protein 1 (HMGB1) is released during tissue damage and activates the innate immune system through toll-like receptor 4. Because mortality in dilated cardiomyopathy (DCM) is associated with activation of the innate immune system, we hypothesized that HMGB1 possesses a prognostic value in estimating mortality in patients with DCM. We determined HMGB1 and N-terminal B-type natriuretic peptide (NT-proBNP) levels in 67 patients with DCM (12 women, mean age 53.6 ± 1.5 years). Kaplan-Meier analyzes revealed that higher levels of HMGB1 and NT-proBNP are related to increased all-cause mortality. Multivariable Cox regression confirmed HMGB1 as a risk factor for mortality in patients with DCM, independent of NT-proBNP, age, and gender (hazard ratio per 1 SD 1.920, 95% confidence interval 1.401 to 2.631, p <0.001). HMGB1 is a promising candidate to estimate the prognosis of patients with DCM.
高迁移率族蛋白 B1(HMGB1)在组织损伤时释放,并通过 toll 样受体 4 激活先天免疫系统。由于扩张型心肌病(DCM)患者的死亡率与先天免疫系统的激活有关,我们假设 HMGB1 在估计 DCM 患者死亡率方面具有预后价值。我们测定了 67 例 DCM 患者(12 例女性,平均年龄 53.6±1.5 岁)的 HMGB1 和 N 末端 B 型利钠肽(NT-proBNP)水平。Kaplan-Meier 分析显示,HMGB1 和 NT-proBNP 水平较高与全因死亡率增加相关。多变量 Cox 回归证实,HMGB1 是 DCM 患者死亡的危险因素,独立于 NT-proBNP、年龄和性别(每 1 SD 的危险比为 1.920,95%置信区间为 1.401 至 2.631,p<0.001)。HMGB1 是估计 DCM 患者预后的有前途的候选物。
