Prim Care Diabetes:河南学者研究称血压高预示未来患糖尿病!

2020-03-26 xujing 中国循环杂志

河南学者联合深圳学者发表基于中国农村人口的大样本队列研究发现,随着平均动脉压的增加,女性患2型糖尿病的风险增加。平均动脉压 = 1/3×收缩压 + 2/3×舒张压。

河南学者联合深圳学者发表基于中国农村人口的大样本队列研究发现,随着平均动脉压的增加,女性患2型糖尿病的风险增加。平均动脉压 = 1/3×收缩压 + 2/3×舒张压。

研究数据显示,与平均动脉压<80 mmHg者相比,平均动脉压为90-100 mmHg和>100 mmHg的女性患2型糖尿病的风险分别增加74%和84%。

研究纳入12284人,这些人在基线时没有2型糖尿病。随访6.01年后,847人新发2型糖尿病。

平均动脉压与2型糖尿病发病相关的病理生理机制尚未明确。研究者分析,可能与以下四点有关:

平均动脉压升高通常与收缩压和/或舒张压升高有关,而血压升高导致内皮功能障碍,这可能影响胰岛素分泌,导致胰岛素抵抗,进而导致2型糖尿病的发生、发展。

此外,血压升高,血管收缩,外周组织血流减少,葡萄糖分解受阻,导致2型糖尿病。

高血压水平与炎症标志物(如C-反应蛋白和白细胞介素6)的升高有关,这些炎症标志物可能通过与胰岛素信号通路和细胞功能的相互作用而参与2型糖尿病的病理和生理学过程。

平均动脉压是血管僵硬的替代指标。动脉僵硬可能导致组织灌注受损,胰岛素介导的葡萄糖代谢受损。
