Peripheral arterial disease (PAD) is one of the most disabling cardiovascular complications of type 2 diabetes mellitus and is indeed associated with a high risk of cardiovascular and limb adverse events. High mobility group box-1 (HMGB-1) is a nuclear protein involved in the inflammatory response that acts as a pro-inflammatory cytokine when released into the extracellular space. HMBG-1 is associated with PAD in diabetic patients. The aim of this study was to evaluate the association between serum HMGB-1 levels and major adverse cardiovascular events (MACE) and major adverse limb events (MALE) after lower-extremity endovascular revascularization (LER) in a group of diabetic patients with chronic limb-threatening ischemia (CLTI).
We conducted a prospective observational study of 201 diabetic patients with PAD and CLTI requiring LER. Baseline serum HMGB-1 levels were determined before endovascular procedure. Data on cardiovascular and limb outcomes were collected in a 12-month follow-up.
During the follow-up period, 81 cases of MACE and 93 cases of MALE occurred. Patients who subsequently developed MACE and MALE had higher serum HMGB-1 levels. Specifically, 7.5 ng/mL vs 4.9 ng/mL (p < 0.01) for MACE and 7.2 ng/mL vs 4.8 ng/mL (p < 0.01) for MALE. After adjusting for traditional cardiovascular risk factors, the association between serum HMGB-1 levels and cardiovascular outcomes remained significant in multivariable analysis. In our receiver operating characteristic (ROC) curve analysis, serum HMGB-1 levels were a good predictor of MACE incidence (area under the curve [AUC] = 0.78) and MALE incidence (AUC = 0.75).
This study demonstrates that serum HMGB-1 levels are associated with the incidence of MACE and MALE after LER in diabetic populations with PAD and CLTI.
外周动脉疾病(PAD)是 2 型糖尿病最常见的心血管并发症之一,确实与心血管和肢体不良事件的高风险相关。高迁移率族蛋白 B1(HMGB-1)是一种参与炎症反应的核蛋白,当其释放到细胞外空间时,作为一种促炎细胞因子发挥作用。HMGB-1 与糖尿病患者的 PAD 有关。本研究旨在评估 201 例糖尿病慢性肢体威胁性缺血(CLTI)患者下肢血管腔内修复(LER)后血清 HMGB-1 水平与主要不良心血管事件(MACE)和主要不良肢体事件(MALE)之间的关系。
我们对 201 例需要 LER 的糖尿病合并 PAD 和 CLTI 的患者进行了前瞻性观察研究。在血管内治疗前确定了基础血清 HMGB-1 水平。在 12 个月的随访中收集了心血管和肢体结局的数据。
在随访期间,发生了 81 例 MACE 和 93 例 MALE。随后发生 MACE 和 MALE 的患者血清 HMGB-1 水平更高。具体而言,MACE 为 7.5ng/mL 比 4.9ng/mL(p<0.01),MALE 为 7.2ng/mL 比 4.8ng/mL(p<0.01)。在校正传统心血管危险因素后,多变量分析显示血清 HMGB-1 水平与心血管结局之间仍存在显著相关性。在我们的接收者操作特征(ROC)曲线分析中,血清 HMGB-1 水平是 MACE 发生率(曲线下面积[AUC] = 0.78)和 MALE 发生率(AUC = 0.75)的良好预测因子。
本研究表明,血清 HMGB-1 水平与糖尿病合并 PAD 和 CLTI 患者 LER 后 MACE 和 MALE 的发生有关。
