Abstract
Objective: There is limited information about the value of exercise
#echocardiography for the prediction of events after #coronaryartery
by-pass #surgery (CABS). Ischemia might be considered of limited value in
patients already revascularized by surgery. We sought to investigate
the value of exercise echocardiography (ExE) for the prediction of major
cardiac events (MACE) and overall mortality in patients submitted to
CABS.
Methods: Retrospective analysis of prospectively collected
data on 568 CABS patients (mean age 66±10 years) who were submitted to a
clinically indicated first treadmill ExE. Normal ExE was defined as the
absence of wall motion abnormalities (WMAs) at rest and at exercise.
Ischemia was defined as the appearance of new WMAs or the worsening of
resting WMAs. Abnormal ExE was defined as #ischemia or the
presence of resting WMAs unchanged with exercise. The end points were
MACE and overall #mortality.
