Stroke:急性卒中后的睡眠呼吸障碍

2016-04-18 fsy 译 MedSci原创

睡眠呼吸障碍是脑卒中患者常见的症状,并造成阻塞性睡眠呼吸暂停(OSA)的发病率高出4到6倍。在急性卒中后期,以色列索罗卡大学医学中心的研究人员前瞻性评估了临床特点,炎症和凝血实验室指标与OSA严重程度的相关性。研究人员对急性缺血性卒中后住进神经内科的患者,在症状发作的最初48h内通过外周动脉张力,一个手腕佩戴动态睡眠研究装置(利用外周动脉张力)进行了评价。研究人员对患者的早晨血样进行了肿瘤坏死因子

睡眠呼吸障碍是脑卒中患者常见的症状,并造成阻塞性睡眠呼吸暂停(OSA)的发病率高出4到6倍。在急性卒中后期,以色列索罗卡大学医学中心的研究人员前瞻性评估了临床特点,炎症和凝血实验室指标与OSA严重程度的相关性。

研究人员对急性缺血性卒中后住进神经内科的患者,在症状发作的最初48h内通过外周动脉张力,一个手腕佩戴动态睡眠研究装置(利用外周动脉张力)进行了评价。研究人员对患者的早晨血样进行了肿瘤坏死因子、白细胞介素6、纤溶酶原激活物抑制剂-1的水平的检测。

共有43例急性脑卒中患者参与此研究,其中22例(51%)患者已发现有中度睡眠呼吸暂停(呼吸暂停低通气指数[AHI]≥15),86%的患者AHI≥5,32.5%的患者有重度OSA(AHI≥30)。OSA患者(AHI≥15)在卒中的严重程度或症状方面没有差异,但他们的复发性卒中和房颤的发病率较高。AHI≥15的患者所有3个生物标志物水平较高:肿瘤坏死因子(6.39 vs 3.57pg/mL)、白细胞介素-6(6.64 vs 3.14pg/mL)和纤溶酶原激活物抑制剂-1(176.64 vs 98.48pg/mL)。通过AHI分为3组(AHI<5,5-14,和≥15)之后,分析结果显示,只有最高AHI组与其他2组中的生物标记物的水平不同。

通过使用bed-side somnography technology技,术结果表明,在急性缺血性卒中未选定的患者样本中,有近90%的患者患有严重的睡眠呼吸障碍。睡眠呼吸障碍显著增加了炎症的生物标志物的水平,这可以提供OSA相关卒中风险可能的病理生理的解释。这些结果前瞻性地筛查了卒中患者睡眠呼吸障碍的存在,并奠定了干预试验的基础理论。

JAMA总结急性卒中预防十大要点

1.在急性缺血性卒中期间,已有核心组织因局部缺血而出现不可逆损伤。该核心组织被缺血半暗带围绕,即低灌注组织,并存在永久性损伤风险,但施以再灌注可以挽救并使其功能恢复正常。急性卒中治疗的目标是恢复缺血半暗带的血流供应。        2.如果静脉注射(iv)组织型纤溶酶原激活剂(tPA)能够在4.5小时内(从患者表现正常的最近的时间到溶栓)给予,则i

Stroke:卒中发生3个月进行阿替普酶治疗是安全的

背景和目的:根据欧洲许可证,卒中后3个月内不能给予阿替普酶治疗。然而,卒中史是否影响治疗效果尚不清楚。研究者旨在评估与第一次卒中相比先前卒中小于3个月进行静脉溶栓治疗后的安全性和功能预后。方法:研究者分析来自12个国家的东欧卒中安全溶栓登记中2003年10月到2014年7月期间应用阿替普酶的患者。应用非校正及校正logistic回归分析计算0R值。结果:13007名患者,11221名(86%)患者
