传统观点认为 ,高血压患者平均动脉压升高是总外周阻力升高和小动脉壁 腔比值增加的结果。最近的研究除考虑血压的稳定部分也考虑其波动部分。平均动脉压在整个“动脉树”中基本保持不变 ,而脉压差从中心大动脉到外周动脉逐渐增加 ,说明每根在体动脉都有其特征的压力曲线。所以
The traditional view that hypertension in patients with elevated mean arterial pressure is increased peripheral resistance and arteriolar wall cavity ratio results. Recent studies consider the fluctuating part of the blood pressure in addition to the stable part. Mean arterial pressure in the entire “Arterial Tree” remained unchanged, and pulse pressure difference from the central aorta to the peripheral arteries gradually increased, indicating that each has its own body artery pressure curve. and so
