Effect estimate: kappa 0.69 vs 0.28
Absolute Event Rate: 96% vs 79%
A novel 3D analysis tool for dobutamine stress echocardiography significantly improves interobserver agreement for detecting myocardial ischemia compared to conventional analysis.
Nemes et al. (2008) conducted an observational in Stable chest pain (n=34). Novel 3D analysis tool vs. Conventional analysis was evaluated on Interobserver agreement on myocardial ischemia (kappa 0.69 vs 0.28). A novel 3D analysis tool improved interobserver agreement for myocardial ischemia compared to conventional analysis during noncontrast (96% vs 79%) and contrast-enhanced (96% vs 90%) 3D DSE.
