Objective:To compare the prognostic significance of Chronotropic function(85%of maximal age-predicted heart rate,heart rate reserve),exercise myocardial perfusion tomography(MPI), post-exercise end-systolic volume(ESV)and left ventricular ejection fraction(EF)in patients with known or suspected coronary artery disease(CAD),probe into the usefulness of risk stratification by multivariate analyses.

目的比較心率變時性功能(次極量心率、心率儲備)、運動SPECT心肌灌注顯像(MPI)結果、左心室收縮末容積(ESV)和左心室射血分數(EF)各自對疑診冠心病(CAD)患者的預后價值;探討多因素結合在患者危險分層中的作用。
