Quantitative Analysis of Function and Perfusion during Dobutamine Stress in the Detection of Coronary Stenoses: Two-Dimensional Strain and Contrast Echocardiography Investigations

Quantitative evaluation of contraction by LS and CS analysis and perfusion (A.b) during stress echocardiography resulted in similar accuracy levels, whereas the radial component was less accurate. Maximal sensitivities and accuracies were obtained by combined evaluations during stress.
