运动试验可以发现安静时不出现的心脏异常,而且运动又是人类最普通的生理性应激,因此运动是估计心脏灌注和功能的最有价值的试验.冠状动脉造影可发现心脏病理解剖方面的改变;相反,运动试验则提供有关心脏功能变化的资料.运动试验应用范围(假定已作出诊断)包括估计预后,评价疾病严重程度,定量测定心脏功能,估价治疗的必要性及其效应.
Exercise tests can detect heart abnormalities that do not occur when they are quiet, and exercise is the most common physiological stress in humans, so exercise is the most valuable test for assessing cardiac perfusion and function. Coronary angiography can be used to find anatomical Exercise tests provide information on changes in heart function.The range of exercise tests (assuming diagnosis has been made) includes estimating the prognosis, assessing the severity of the disease, quantifying cardiac function, assessing the need for treatment, and its effects.
