卒中血管危险因素影响静脉注射组织型纤溶酶原激活剂的结局

2015-08-28 小太阳 译 医学论坛网

静脉注射(IV)组织型纤溶酶原激活剂(tPA)是唯一批准用于急性缺血性脑卒中非侵入性治疗方案。但tPA治疗后,卒中不同亚型依据血管危险因素的结局仍有待阐明。近日,发表在PLOS one上的一项研究探索了不同急性缺血性脑卒中亚型IV tPA治疗后结局与不同危险因素的关系。基于国家健康研究院的卒中测量(NIHSS)评分、90天改进的Rankin评分(mRS)和卒中亚型,研究收集和分析了人口基线资料和血

静脉注射(IV)组织型纤溶酶原激活剂(tPA)是唯一批准用于急性缺血性脑卒中非侵入性治疗方案。但tPA治疗后,卒中不同亚型依据血管危险因素的结局仍有待阐明。

近日,发表在PLOS one上的一项研究探索了不同急性缺血性脑卒中亚型IV tPA治疗后结局与不同危险因素的关系。

基于国家健康研究院的卒中测量(NIHSS)评分、90天改进的Rankin评分(mRS)和卒中亚型,研究收集和分析了人口基线资料和血管危险因素的数据。通过90天mRS,把每个卒中亚组患者分为有利和不利的结局,鉴别哪种血管危险因素与亚组较差的结局相关。

结果发现,在接受IVtPA的570例急性缺血性脑卒中患者中,217例属于大动脉粥样硬化组(LAA),146例属于小血管闭塞组(SVO),140例属于心主动脉栓塞组。在所有亚组,入组时较低的NIHSS评分与良好的结局相关。有血脂异常疾病史,入组前服用他汀的患者,入组后血脂水平几乎没有可能升高。因此,LAA和SVO组会产生有些矛盾的结局。SVO患者伴有糖尿病会有较高的不良结局风险。如果SVO患者发病到治疗间隔时间较短,也会有良好的结局。

研究指出,不同卒中亚型的IV tPA治疗后临床结局与不同血管危险因素相关。
