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.
