摘要

对40例患者（其中35例为临床确诊为冠心病患者，另有5例正常对照）采用携带式心功能仪（VEST）测定心功能，所测得的LVEF值与SPECT测定值的相关性良好，相关系数为0．87，P＜0．001。35例冠心病患者在日常生活中有24例出现一次以上LVEF值降低≥5％，持续1min以上，而且均出现在上楼或行走时，其中5例还同时出现在脑力负荷试验中。24例中83％为隐匿性心肌缺血。5例正常对照组均未见异常LVEF值降低．资料显示VEST能连续提供正常人及冠心病患者日常生活中心脏功能及EKG的各种变化。这对于隐匿性心肌缺血的诊断、预后估测及治疗效果的评价、随访均有重要的意义。

Abstract

Ambulatory radionuclide manitoring of left ventricular function was performedwith the VEST in 35 patients with coronary artery disease and 5 normal subjects. Atransient decrease in left ventricular ejection fraction （5%） lasting over 1 min wasobserved in 24 of the 35 patients with CAD during daily activities

only 4 episodeswere accompanied with chest pain and 20 （83%） were asymptomatic. VEST maycontinuously monitor the change of both left ventricular function and the ECGduring the activities of daily life. It was an accurate and sensitive parameter for thediagnosis of silence myocardial ischemia.
