摘要
A quantitative index for evaluating the performance of artery was introduced according to the idea of energy exchange between arterial wall and blood.The index was studied by using the exponential and parabolic pressure-volume relations or human arteries. Methods for estimating the index in vivo based on aWindkessel model of the arterial system were proposed. Data from patients withcongestive heart failure and hypertension were used for illustration. It was shownthat the index has physiological meaning and is a useful parameter for evaluationthe performance of artery.
