Using venous occlusive plethysmography, venous distensibility was examined in 85 hypertensive patients and in 21 normal men. Venous distensibility in the hypertensive versus normal subjects was significantly lower, being inversely depended on the blood pressure level. Venous distensibility depended directly on the blood flow in the forearm and inversely on the resistance of the resistive vessels at rest. This may indicate that the reduction of venous distensibility was caused by both functional and structural changes characteristic of both resistive and capacitance vessels. It appears that functional and structural alterations in the system of low pressure, along with an elevated resistance of the arterioles, were actively involved in changes of the peripheral resistance and the development of a hypertensive state.
利用静脉闭塞体积描记法，对85例高血压患者和21名正常男性的静脉扩张性进行了检测。高血压患者与正常受试者相比，静脉扩张性显著降低，且与血压水平呈负相关。静脉扩张性直接取决于前臂血流量，与静息时阻力血管的阻力呈负相关。这可能表明，静脉扩张性降低是由阻力血管和容量血管特有的功能和结构变化共同导致的。似乎低压系统中的功能和结构改变，以及小动脉阻力升高，都积极参与了外周阻力的变化和高血压状态的发展。
