Abstract To determine whether the accuracy of exercise echocardiography is affected by the
degree of effort during exercise, we examined 101 patients who had 6 months earlier
undergone successful coronary artery angioplasty, with resting and immediate postexercise
echocardiography and same-day coronary angiography. A positive exercise
echocardiographic response was defined as the development of a new or worsening wall
motion abnormality postexercise, compared with resting wall motion.
