JAHA:高血糖、随后卒中风险和双重抗血小板治疗疗效分析

2022-01-20 MedSci原创 MedSci原创

就诊时的高血糖与高危短暂性脑缺血发作或轻微卒中后复发性缺血性卒中风险增加相关。快速、简单的血清葡萄糖水平测定可能是一种有用的生物标志物,以用于识别后续缺血性卒中风险特别高的患者。

每次缺血性卒中都意味着是预防另一次可能更严重的卒中的关键机会。在卒中事件发生后的90天内,随后发生卒中的风险高达17%。四分之一的卒中是其他疾病的结局性事件。目前尚不清楚较高的血糖水平是否与高危短暂性脑缺血发作或轻度缺血性卒中后复发性卒中风险增加相关。

近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员对POINT(新发TIA和轻度缺血性卒中患者血小板导向抑制)试验进行了二次分析,以评估参加试验前血清高血糖(≥180mg/dL)与血糖正常(<180mg/dL)与90天结局之间的关系。该研究的主要终点是由多变量Cox模型模拟的随后的缺血性卒中发生情况,并调整了年龄、性别、种族、民族、研究治疗分配、指标事件和主要合并症。

在纳入这项研究的4878名患者中,267名患者发生复发性卒中。与血糖正常的患者相比,高血糖患者发生卒中的风险更高(调整后的风险比[HR]为1.50[95%CI为1.05-2.14])。

双重抗血小板治疗与高血糖患者后续卒中风险降低无关(HR为1.18[95%CI为0.69-2.03]),尽管宽置信区间并不排除治疗效果。当采用连续变量建模时,有证据表明血糖与随后的卒中风险之间存在非线性关联(P<0.001)。

由此可见,就诊时的高血糖与高危短暂性脑缺血发作或轻微卒中后复发性缺血性卒中风险增加相关。快速、简单的血清葡萄糖水平测定可能是一种有用的生物标志物,以用于识别后续缺血性卒中风险特别高的患者。
