NEJM:MRI指导阿替普酶溶栓治疗用于发病时间未知的脑血栓患者

2018-05-18 zhangfan MedSci原创

研究认为对于发病时间未知的急性脑血栓患者,如果MRI指征证实可接受阿替普酶溶栓治疗,则患者90天预后较安慰剂治疗可显著得到改善

现行指南中,静脉溶栓治疗仅限用于症状发生后4.5小时以内的患者。近日研究人员考察了阿替普酶治疗对发病时间未知脑血栓患者的治疗效果。

在这项多中心研究中,脑栓塞发病时间不明的患者接受静脉阿替普酶或安慰剂治疗。所有参与者磁共振弥散加权成像可见缺血性病变,而液体衰减反转恢复(FLAIR)无实质高强度病变,符合阿替普酶的治疗指征。研究的主要终点为90天预后良好,即Rankin神经病变得分0或1,次要终点为阿替普酶治疗的优越性。

研究原计划招募800名患者,在招募503名患者后因治疗效果显著而提前终止。总计254名患者接受阿替普酶治疗,249人接受安慰剂。90天后,阿替普酶组131人(53.3%)以及安慰剂组102人(41.8%)预后良好。阿替普酶组90天平均Rankin得分为1分,安慰剂组为2分。阿替普酶组10人以及安慰剂组2人死亡(4.1% vs 1.2%), 阿替普酶组症状性颅内出血的发生率为2.0%,安慰剂组为0.4%。

研究认为对于发病时间未知的急性脑血栓患者,如果MRI指征证实可接受阿替普酶溶栓治疗,则患者90天预后较安慰剂治疗可显著得到改善。

注意:老年脑血栓七大症状警示

目前,脑血管病位居世界致命性疾病中的第二位,其中缺血性脑血管病,也是我们俗称的脑梗塞和脑血栓这一类疾病,占到整个脑血管疾病发病率的75%左右。它的致死率致残率都是非常高的。专家强调,中老年人一定要注意脑血栓的前兆,发现后要抢在黄金时间窗内送到医院急救。 1. 突然发生眩晕 眩晕是脑血栓的前兆中极为常见的症状,可发生在脑血管病前的任何时段,尤以清晨起床时发生得最多。此外,在疲劳、洗澡后也易发生。

同样是脑血栓,为什么中国那么多老人杵拐棍?

同样是脑卒中患者,中美两国患者的结局却截然不同——在美国,许多脑卒中患者康复以后可以和正常人一样生活工作,而在中国,患者往往可能出现严重后遗症失去生活自理和工作能力。 原因何在?中国康复医学会康复治疗专委会副主委、上海市第一人民医院康复科主任陈文华教授说,除了患者对脑卒中症状的早期识别、及时就诊之外,康复医疗的缺位是导致患者致残的主要因素。 现代医学有4个家族成员,预防医学、保健医学、临床医学

脑梗死、脑血栓及脑出血的区别

1、脑梗死(脑梗、脑梗塞、缺血性脑卒中):脑梗是脑动脉阻塞后出现相应部位脑组织的破坏,可伴发出血。发病机制为血栓形成或栓塞,症状的性质因病变累及的血管不同而异。脑梗占全部脑卒中的 70%~80%。
