Comparison of coronary flow reserve feasibility in different stress echocardiography protocols: dobutamine, dipyridamole, exercise and rapid pacing.
The assessment of coronary flow velocity reserve (CFVR) may improve the diagnostic and prognostic value of stress echocardiography (SE). ⋯ CFVR in the LAD can be obtained during all forms of SE, but the feasibility is significantly higher with rapid cardiac pacing and pharmacological tests as compared with exercise, which was identified in our study as an independent predictor of the loss of blood flow during a blood flow recording in the LAD at the peak of stress test.
