Ann Rheum Dis :颈动脉超声可用于评估RA患者心血管风险

2014-03-21 佚名 丁香园

类风湿关节炎(RA)可促使动脉硬化加速发生,增加了患者因心血管(CV)事件而导致的死亡率。为研究颈动脉超声检查(US)是否有助于对RA患者进行CV风险分层,来自西班牙桑坦德Marqués de Valdecilla大学医院的Corrales博士等人进行了一项研究。研究发表于2014年3月的Ann Rheum Dis杂志上。研究发现,颈动脉超声可用于评估RA患者心血管风险。 研究纳入了370例无C

类风湿关节炎(RA)可促使动脉硬化加速发生,增加了患者因心血管(CV)事件而导致的死亡率。为研究颈动脉超声检查(US)是否有助于对RA患者进行CV风险分层,来自西班牙桑坦德Marqués de Valdecilla大学医院的Corrales博士等人进行了一项研究。研究发表于2014年3月的Ann Rheum Dis杂志上。研究发现,颈动脉超声可用于评估RA患者心血管风险。

研究纳入了370例无CV事件史的RA患者,使用超声测量患者颈动脉内-中膜厚度(cIMT)并检查是否存在斑块。EUALR系统性冠状动脉风险(SCORE)评分及修正SCORE(mSCORE)评分对CV风险分层如下:低风险(<1%)、中风险(≥1%并<5%),高风险(≥5%并<10%),极高风险(≥10%)。根据mSCORE评分,凡以下3条特别标准满足2条以上者,其CV风险评分应乘1.5:(1)病程超过10年;(2)类风湿因子(RF)或抗环瓜氨酸抗体(抗CCP)阳性;(3)出现关节外症状。

纳入患者的平均病程为9.8年,其中250例(68%)患者存在RF或抗CCP抗体阳性,61例(17%)存在关节外症状。43例患者因合并2型糖尿病或严重的慢性肾脏病而被排除研究。剩余的327例RA患者根据mSCORE评分进行CV风险分层,结果如下:96例患者(29.3%)为低风险,201例患者(61.5%)为中风险,30例患者(9.2%)为高/极高风险。

与SCORE评分相比,5例患者通过mSCORE评分从中风险上升为高/极高风险。严重的颈动脉US异常(cIMT>0.9 mm和/或存在斑块)在mSCORE评分为低风险的患者组中较少见(13%)。然而,在mSCORE评分为中风险的患者组中,严重的颈动脉US异常在63%的患者中被确认。mSCORE评分高风险(≥5%)、mSCORE评分中风险(≥1%并<5%)合并颈动脉US严重异常,对高/极高CV风险的高度敏感。

该研究结果提示,颈动脉US可用于RA患者的CV风险评估。

Stroke:颈动脉外膜灌注成像有助研究斑块发病机理

活检研究提示斑块内出血与血管滋养管存在相关,后者主要来自外膜。颈动脉外膜血管滋养管能够通过动态增强MRI以估计灌注参数得以确定。为此,美国华盛顿大学影像科的Jie Sun与北京医院影像科的Yan Song使用动态增强MRI进行了一项研究。研究结果在线发表在2013年3月7日的Stroke杂志上。研究结果显示:外膜和斑块内出血存在独立的生理病理联系。它们的联系在于外膜血管滋养管的微结构。外膜灌注成像
