Background Caffeine attenuates the coronary hyperemic response to adenosine by
competitive A 2A receptor blockade. This study aims to determine whether oral caffeine …

A multicenter, double-blind, randomized study was conducted to assess the effect of caffeine
on regadenoson stress myocardial perfusion imaging (MPI). Subjects with a high likelihood …

The antagonistic effects of caffeine on adenosine receptors are a possible cause of false-
negative stress perfusion imaging. The purpose of this study was to determine the effects of …

Abstract Purpose Regadenoson, an A 2A adenosine receptor pharmacologic stress agent
for radionuclide myocardial perfusion imaging (MPI), is administered as a single, fixed dose …

Aminophylline has long been used in the reversal of vasodilators used for myocardial
perfusion imaging. However, in 2010, manufacturers of aminophylline reported shortages …
