Stroke:缺血性中风患者兄弟姐妹生存情况与患者本人死亡风险有关!

卒中后兄弟姐妹生存期短的家族史与年轻男性卒中后的死亡率有关。

急性缺血性卒中是颅内动脉血管狭窄或闭塞引起的局部脑组织缺血、缺氧所导致的缺血性坏死,病残率和病死率较高,尤其是后循环缺血性卒中的病残率和病死率高达80%以上,严重影响患者生活质量,并加重家庭和社会医疗与经济负担。

中风是我国死亡和成人残疾的主要原因,每年有超过1300万的中风和2390万的短暂性脑缺血发作(TIA)。尽管有中风和TIA有循证治疗和指南,但全国范围内在遵守循证中风和TIA护理方面仍然存在差异。

然而,家族因素对缺血性卒中预后的影响尚不清楚。为此,来自瑞典隆德大学/斯科尼地区初级卫生保健研究中心的专家开展了一项全国性的随访研究,评估了因缺血性脑卒中而住院的瑞典兄弟姐妹中卒中的家族性死亡风险,结果发表在Stroke杂志上。

研究人员使用瑞典全国范围内的登记册确定了1380对瑞典出生的兄弟姐妹(2760例),其中兄弟姐妹都在1991年至2010年间因首次卒中住院治疗。中位年龄为62岁(范围为26-78岁)。用Cox回归法确定首次卒中住院后死亡率的家族危险比(FHRs)。卒中后亲属生存的影响被分为短生存(<12345年)或长生存(≥12345年)。

结果显示,卒中后兄弟姐妹短存活率(即<3或<4年)与调整后的FHR有关,卒中后的总死亡率分别为1.29(95%CI,1.05-1.58)和1.24(95%CI,1.02-1.51)。分层分析显示,兄弟姐妹短生存率(即<2-<5年)仅在年轻个体(<62岁)和男性中更强和更有意义。

对于年轻个体来说,兄弟姐妹短生存期(即<4年)的最高FHR为1.42(95%CI,1.08-1.88),男性为1.50(95%CI,1.21-1.87)。对于年轻的男性受试者,FHR是1.80(95% CI,1.33-2.46)。在调整后的模型中,死亡率还与性别、教育、发病年龄、诊断年份、住院天数、冠心病、糖尿病、痴呆症、心衰、肥胖、酗酒和高脂血症有关。

综上,该结果表明,卒中后兄弟姐妹生存期短的家族史与年轻男性卒中后的死亡率有关。未来需要进行更多的研究,以确定这种关联的可能的遗传和非遗传性的家族环境原因。
