Relationship Between Post-Systolic Motion During Dobutamine Stress Echocardiography and Functional Recovery of Myocardium After Successful Percutaneous Coronary Intervention

摘要

Background and ObjectivesDoppler myocardial imaging (DMI) has been suggested as a method of quantifying inducible ischemia during dobutamine stress echocardiography (DSE). Post-systolic motion (PSM) detected by DMI is related to peri-infarct ischemia during DSE. We hypothesized that PSM during DSE would predict recovery of dysfunctional myocardium after successful percutaneous coronary intervention (PCI).
