The clinical utility of stress testing in patients without angina pectoris after revascularization
has been questioned. Dobutamine stress echocardiography (DSE) is an established technique
for detection of myocardial ischemia and cardiac risk stratification. We studied the
prognostic value of DSE in 393 patients without typical angina pectoris after coronary
revascularization. Ischemia was incremental to clinical data in predicting all-cause
death (hazard ratio 3.5, 95% confidence interval 1.8 to 6.7) and cardiac death (hazard
ratio 4.2, 95% confidence interval 1.8 to 9.8). In conclusion, myocardial ischemia
during DSE is independently associated with an increased risk of all-cause mortality
and cardiac death in these patients after adjustment for clinical data.
