Abstract:
Objective To determine the accuracy and usefulness of dobutamine stress echocardiography(DSE) in detecting restenosis after percutaneous coronary intervention (PCI). Methods DSE was conducted in 47 patients before coronary angiography, 6 months to 18 months after PCI. The standard protocol of DSE was 5,10,20,30 ?g?kg~(-1)?min~(-1) with subsequent incremental increases every 3 minutes to a maximum dose of 40 ?g?kg~(-1)?min~(-1). Consistency of the results was compared between DSE and coronary angiography.Results Compared with coronary angiographic results, DSE had a low sensitivity(64%) but high specificity(86%) for detection of restenosis after PCI. The total accuracy was 72%. Conclusions DSE can assess restenosis after PCI with lower cost and safety.
