To assess the prognostic value of exercise echocardiography in patients wit
h prior coronary artery bypass surgery, follow-up was obtained in 718 patie
nts (591 men [82%] and 127 women [18%], aged 67 +/- 9 years) who underwent
clinically indicated exercise echocardiography 5.7 +/- 4.7 years after coro
nary bypass surgery, Resting wall motion abnormalities were present in 479
patients (67%), New or worsening wall motion abnormalities developed with e
xercise in 366 patients (51%). During a median follow-up of 2.9 years, card
iac events included cardiac death in 36 patients and nonfatal myocardial in
farction in 40 patients. The addition of the exercise echocardiographic var
iables, abnormal left ventricular end-systolic volume response and exercise
ejection fraction to the clinical, resting echocardiographic and exercise
electrocardiographic model provided incremental information in predicting c
ardiac events (chi-square 37 to chi-square 42, p = 0.02) and cardiac death
(chi-square 38 to chi-square 43, p < 0.02), Exercise echocardiography provi
