Figure 7From: Regadenoson and adenosine are equivalent vasodilators and are superior than dipyridamole- a study of first pass quantitative perfusion cardiovascular magnetic resonanceA, B and C: correlation between heart rate and MBF is shown in a two-drug comparison. As shown in 7A, adenosine has a parallel upward shift ie. a higher MBF for the same heart rate, compared to dipyridamole. In contrast, regadenoson has an upward and rightward shift i.e. higher MBF and heart rate when compared to dipyridamole and adenosine as shown in 7B and C respectively.Back to article page
