Dobutamine stress echocardiography: angiographic correlates
Annals of the Academy of Medicine, Singapore
|March 1, 1996
Summary
Dobutamine stress echocardiography (DSE) accurately identifies coronary artery disease (CAD). This non-invasive test effectively detects CAD presence and location, aiding in patient diagnosis and treatment planning.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Dobutamine stress echocardiography (DSE) is a valuable non-invasive tool.
- Evaluating its utility in diagnosing coronary artery disease (CAD) is crucial.
Purpose of the Study:
- To determine the diagnostic utility of DSE in identifying coronary artery disease (CAD).
- To correlate DSE findings with angiographic data in a clinical setting.
Main Methods:
- Retrospective analysis of 300 DSE procedures performed between September 1992 and January 1994.
- Correlation of DSE results with cardiac catheterization data in 64 patients without interim cardiac events.
Main Results:
- DSE demonstrated a sensitivity of 89% and specificity of 82% for detecting significant obstructive CAD.
- Positive and negative predictive values were 86% and 85%, respectively.
- High sensitivity for single-vessel (94%) and multivessel (84%) disease was observed, with accurate localization in 81% of single-vessel cases.
Conclusions:
- Dobutamine stress echocardiography is a highly accurate method for evaluating coronary artery disease.
- DSE effectively identifies patients with CAD and helps pinpoint the location of the disease.
