慢性高血压可能会损害大脑输液. 在内狭窄症患者中,严格控制低于140/80mmHg的血压,可以进一步降低侧脑输液.
科学领域:
- 神经学 神经学
- 心血管医学 心血管医学
- 医疗成像医学成像
背景情况:
- 慢性高血压是已知的缺血性中风和较差结果的风险因素.
- 对于患有严重内狭窄症的高血压患者来说,最佳的血压目标仍在争论中.
研究的目的:
- 评估不同血压水平对中脑动脉 (MCA) 严重狭窄或封闭的患者的大脑输液的影响.
主要方法:
- 105名患有隔离的狭闭性MCA的患者,通过数字减去血管学 (DSA) 确认,接受了输液加权成像 (PWI).
- 在高血压和非高血压组之间分析了风险因素.
- 多变量逻辑回归确定了高血压和PWI值之间的独立关联.
- 对不同血压水平的脑输液进行了比较.
主要成果:
- 与非高血压患者相比,高血压患者表现出较低的脑输液压,相对平均传输时间 (rMTT) 增加.
- 高血压在调整年龄,糖尿病和纤维素因子后与rMTT独立相关.
- 与非高血压患者相比,在静脉血压<140mmHg和静脉血压<80mmHg的高血压患者中观察到rMTT的显著差异.
结论:
- 慢性高血压可能会对大脑输液产生负面影响.
- 在患有内动脉狭窄的高血压患者中,严格控制血压 (<140/80mmHg) 可能会导致脑外侧脑输液进一步减少.

Blood Pressure
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
