This study was undertaken to detect residual myocardial ischemia in patients early after surgical revascularization (CABG) and to examine prognostic significance of the results of dipyridamole echocardiographic stress test (DPE).
Methods: 60 consecutive patients with complete surgical revascularization were included in the study. Patients underwent echocardiographic examination at rest before operation (A), and next 2 weeks (B), 6 months (C) and 12 months (D) after CABG. DPE was performed before and 2 weeks after CABG, Left ventricular ejection fraction (LVEF), wall motion score index (WMSI) and %area of asynergy (AA) were measured at rest and after dipyridamole.
Results: Resting values of functional parameters were as follows:

DPE was positive in 50 (83%) patients before CABG and in only 2 (3%) patients after CABG. These two patients developed unstable angina during follow-up. There were no deaths and myocardial infarctions. In conclusion, dipyridamole stress test proves a good coronary reserve early after CABG. Positive test was of prognostic importance for prediction of cardiac events.
