May support proceeding with adenosine MPI despite recent caffeine intake; leaves open need for prospective confirmation.
Does caffeine consumption prior to testing alter myocardial perfusion SPECT imaging during adenosine pharmacologic stress?
Routine caffeine consumption prior to adenosine stress testing may not clinically significantly alter myocardial perfusion SPECT imaging, potentially challenging the need for strict abstinence and reducing procedural delays.
Kovacs et al. (2008) conducted a review in Myocardial perfusion imaging during adenosine pharmacologic stress. Caffeine consumption vs. Caffeine abstinence (12 to 24 hours) was evaluated on Adenosine-induced hyperemia during myocardial SPECT imaging. Routine caffeine consumption prior to adenosine myocardial perfusion imaging may not significantly alter hyperemia or necessitate test cancellation based on current review data.
