Additive Prognostic Value of Coronary Flow Reserve in Patients With Chest Pain Syndrome and Normal or Near-Normal Coronary Arteries
2009, American Journal of CardiologyCitation Excerpt :Estimated flow reserve can be accurate if the coronary functions only as a conduit, without changing in diameter during drug infusion. This assumption is reasonable with dipyridamole29,30 and less valid with dobutamine; this is an additional reason to stress CFR with vasodilators. Our study design was observational, not randomized, and the analysis was retrospective, although the data were acquired in a prospective fashion and entered into the databank at the time of initial assessment.
Head to Head Comparison Between Perfusion and Function During Accelerated High-Dose Dipyridamole Magnetic Resonance Stress for the Detection of Coronary Artery Disease
2008, American Journal of CardiologyCitation Excerpt :The challenge to the intuitive appeal of our approach is that vasodilatory stress can be suboptimal for the induction of WM. However, this is true only if low doses of vasodilators are used, which are optimal for perfusion imaging. When high doses of vasodilators are used in a short time (as in our study), the ischemic effect of brisk vasodilatation is at least as strong as that of high-dose dobutamine or maximal exercise.4,5,18–21 The pathophysiologic basis of this effect is the inappropriate excessive accumulation of endogenous adenosine, leading to vertical and horizontal steal phenomena with true subendocardial hypoperfusion.1,22
Simultaneous Analysis of Wall Motion and Coronary Flow Reserve of the Left Anterior Descending Coronary Artery by Transthoracic Doppler Echocardiography during Dipyridamole Stress Echocardiography

2003, Journal of the American Society of EchocardiographyUsefulness of coronary flow reserve over regional wall motion when added to dual-imaging dipyridamole echocardiography
2003, American Journal of CardiologyCitation Excerpt :Recently, extensive evidence also has been found with vasodilator imaging (with dipyridamole or adenosine), and with the simultaneous assessment of LAD CFR by transesophageal or transthoracic echocardiography. These procedures have shown excellent diagnostic results for the noninvasive prediction of angiographically assessed coronary artery disease.11–14 The main limitation of the CFR approach is that only the LAD artery can consistently be evaluated, and the specificity is low in a selected population with microvascular disease and normal coronary arteries8; these patients often undergo stress testing imaging on the basis of electrocardiographic positivity.
