ACC:血压与认知衰退、痴呆及全因死亡率的关系

2022-04-06 网络 网络

本研究旨在挖掘长期累积血压暴露是否与认知能力下降、痴呆事件及全因死亡率相关。

既往“累积血压暴露”的研究多聚焦在其与心血管疾病风险的关系上,对认知能力、痴呆事件研究的比较少,本研究旨在挖掘长期累积血压暴露是否与认知能力下降、痴呆事件及全因死亡率相关。

研究方法

本研究共纳入16860名年龄≥50岁的认知健康成年人,其中7566名参与者来自HRS,9294名来自ELSA,其中男性的占比分别为44.8%、40.2%,中位年龄分别为62岁和65岁。研究者通过测量收缩压(sBP)、舒张压(dBP)、和脉压以及记录参与者老龄化状态,中位随访年龄均为8.0年。协变量包括年龄、性别、白人或非白人种族、心血管危险因素、任何心脏病、癌症和慢性肺病史、当前吸烟

研究结果

  • 在50岁以上认知健康的长期累积血压与随后的认知能力下降、痴呆症风险和全因死亡率相关这种关联独立于其他血管危险因素
  • 对于累积收缩压和脉压暴露风险的人群而言,长期暴露量升高与认知能力加速下降、痴呆症和全因死亡率的风险增加有关。此外,脉压对sBP预测认知缺陷和死亡率方面具有附加价值。
  • 对于累积 dBP暴露风险人群,长期暴露量升高与认知衰退减缓以及痴呆症和全因死亡率风险降低相关。

结论:

在 50 岁以上的认知健康成人中,长期累积血压与随后的认知能力下降、痴呆风险和全因死亡率相关。这意味着,对于这部分人群需要努力控制长期收缩压和脉压,并保持足够的舒张压
