JAHA:心脏肥大与大脑衰老相关

2021-09-01 网络 网络

LV直径和质量与较低的整体和区域性CT以及一般人群中较大的WMH负担相关。这些结果突出了LV肥大与认知能力下降和痴呆之间相关性的大脑结构基础。

最近,有研究报道左心室(LV)肥大与老年人脑结构的不良变化相关,尤其是白质高信号(WMH)的负担增加。

近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,尚不清楚更大的LV大小或质量是否也与中年人的WMH负担相关。此外,迄今为止尚未研究分析其与脑皮质厚度(CT)变化之间的关系。


该研究纳入了1602名LV射血分数>40%且无心肌梗死病史的SHIP(波美拉尼亚健康研究)参与者的数据(年龄为21-82岁;中位年龄为49岁;53%为女性)。参与者接受了头部的超声心动图和磁共振成像检查。脑衰老的成像标志物(即CT和WMH体积)由磁共振成像扫描结果来确定。

LV质量和直径与较低的整体CT和较大的WMH体积相关,同时调整年龄、性别、身高、无脂肪体重和颅内体积。此外,室间隔和后壁的厚度也与较低的整体CT相关。这些关联不能用心血管危险因素(包括高血压)、炎症标志物或社会人口学因素来解释。

由此可见,LV直径和质量与较低的整体和区域性CT以及一般人群中较大的WMH负担相关。这些结果突出了LV肥大与认知能力下降和痴呆之间相关性的大脑结构基础。
