概括
输液压,而不是脉冲压,与年轻成年人早期器官损伤的迹象更为密切相关. 这一发现有助于理解心血管变化,并为未来高血压干预提供信息.
科学领域:
- 心血管研究研究心血管研究
- 高血压研究 高血压研究
- 预防性心脏病学 预防性心脏病学
背景情况:
- 高血压是亚临床目标器官损伤 (TOD) 和心血管疾病 (CVD) 的主要危险因素.
- 关于不同血压测量和亚临床TOD之间的关联,特别是在年轻人群中,人们的理解有限.
- 这项研究研究了压力测量和年轻成年人器官损伤早期迹象之间的关系.
研究的目的:
- 为了比较亚临床TOD标记物和 perfusion 压力与年轻成年人的脉动压力之间的关联的强度.
- 为了确定哪种压力测量方法是年轻人群中亚临床TOD的更好指标.
- 提供与高血压有关的心血管变化的早期机制的见解.
主要方法:
- 分析了非洲PREDICT研究中的1187名年轻成年人的数据.
- 门诊平均动脉压 (MAP) 和脉冲压 (PP) 的测量.
- 亚临床TOD标志物的评估:左心室质量指数 (LVMi),心动脉内膜介质厚度 (cIMT),心动脉-大腿脉冲波速 (cfPWV),中枢视网膜动脉等效 (CRAE) 和白蛋白与肌素比率 (ACR).
主要成果:
- 在未经调整的模型中,亚临床TOD标记物 (cIMT,cfPWV,CRAE) 与输液压的关联比脉动压强.
- 经过调整后的分析证实cfPWV和CRAE与输液压相比,与脉冲压相比,与输液压有更强的联系.
- 考虑到不可修改和可修改的风险因素后,这些关联仍然很重要.
结论:
- perfusion 压力与亚临床 TOD 标志物相比,在年轻,健康的成年人中,脉动压力与 TOD 标志物相比更强烈.
- 这些发现增强了对早期心血管变化和TOD发展的理解.
- 结果可能会为管理高血压和预防心血管疾病的未来干预策略提供信息.

Blood Pressure
3.0K
The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Measurement of Blood Pressure
905
Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...
