Arterial stiffness/elasticity plays a major role in the pathogenesis of heart failure beyond arterial blood pressure. Arterial wave reflections are generated from the periphery of the vascular system, especially at the level of the small arteries. The pattern change of the arterial wave reflections can alter the ventricular-vascular coupling in a pathologic manner, leading to heart failure. Several noninvasive techniques are used to estimate arterial stiffness/elasticity. Small artery elasticity has important predictive value for the diagnosis of heart failure. The beneficial effect of some cardiovascular therapy on arterial stiffness/elasticity has potential to prevent or delay the progression of heart failure.
动脉僵硬度/弹性在心力衰竭的发病机制中起着比动脉血压更为重要的作用。动脉波反射是由血管系统的外周,特别是小动脉水平产生的。动脉波反射模式的改变可以病理性地改变心室-血管耦联,导致心力衰竭。有几种非侵入性技术可用于估计动脉僵硬度/弹性。小动脉弹性对心力衰竭的诊断具有重要的预测价值。一些心血管治疗对动脉僵硬度/弹性的有益影响有可能预防或延缓心力衰竭的进展。
