Stroke:短发性房性快速心律失常是卒中的危险因素

2018-01-16 脑血管病及重症文献导读 杨中华

房颤是心源性卒中的首要病因。短暂发作性房性快速心律失常(atrial tachyarrhythmia,AT)常于普通人群Holter监测中被检测到,可能与心房重塑和房颤诱发有关。不过,短暂发作性AT与卒中的发生率之间的关系尚存争论。另外,短暂发作性AT与房颤的发生之间的关系也不清。


房颤是心源性卒中的首要病因。短暂发作性房性快速心律失常(atrial tachyarrhythmia,AT)常于普通人群Holter监测中被检测到,可能与心房重塑和房颤诱发有关。不过,短暂发作性AT与卒中的发生率之间的关系尚存争论。另外,短暂发作性AT与房颤的发生之间的关系也不清。

2017年12月来自台北的Shinya Yamada等在Stroke上发表了他们的研究结果,目的在于探讨24h Holter监测到的短暂发作性AT与临床事件(包括卒中和房颤)的关系,另外评价了合并短暂AT新发卒中患者采用CHA2DS2-VASc评分作为风险评价工具的价值。

该研究纳入了5342例无房颤无卒中的受试者,并且都进行了24h Holter监测。短暂性AT(short-run AT)定义为发作性室上性异位搏动 (supraventricular ectopic beats),持续时间<5秒。

1595例(29.8%)监测到短暂性AT。经过平均9年的随访,494例发生了卒中。与无短暂AT相比,合并短暂AT者卒中发生率明显升高(11.4% versus 8.3%; P<0.001)。在合并短暂AT的患者中,CHA2DS2-VASc评分0和1分者每100患者-年卒中数量分别为0.23和0.67。CHA2DS2-VASc评分2、3、4和>=5者卒中数量分别为1.62、1.89、1.3和2.91。在CHA2DS2-VASc评分0或1分的患者中,年龄(>61岁)和房早(premature atrial contractions)负荷(>25次/天)独立预测卒中风险。在亚组分析中,基于CHA2DS2-VASc评分将短暂AT患者分为3组:低分组(0分[男]或1分[女],n=324),中间分组(1分[男]或2分[女];n=275),高分组(>=2分[男性]或>=3分[女性],n=996)。与低分值者比较,中间分组和高分组都是卒中的独立预测因子(HR分别为6.165和8.577;P值皆小于0.001)。

最终作者认为短暂AT增加卒中风险。CHA2DS2-VASc可以用于危险分层。对于CHA2DS2-VASc评分0或1分者,年龄和房早的负荷是卒中独立预测因子。
