Abstract
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 des prognostic information in patients after coronary artery bypass surgery , incremental to clinical, rest echocardiographic, and exercise electrocard iographic variables, <(c)>2001 by Excerpta Medico, Inc.
