DOES HEMODYNAMIC RESPONSE DURING REGADENOSON STRESS MYOCARDIAL PERFUSION IMAGING PREDICT PRESENCE OR ABSENCE OF ISCHEMIA ?

Regadenoson Cardiac Stress Myocardial Perfusion Scintigraphy

Determinants of myocardial perfusion reserve measured from coronary sinus phase-contrast imaging during regadenoson stress CMR

Background Measurement of myocardial perfusion reserve (MPR) can potentially extend the scope of conventional myocardial perfusion imaging from detection of flow limiting epicardial stenosis to assessment of coronary microvascular function. Recent studies have suggested that MPR may improve risk stratification of patients with known or suspected CAD. MPR has traditionally been measured using PE...

Regadenoson for myocardial perfusion imaging: Is it safe?

Regadenoson is currently the most widely used pharmacologic stress agent for myocardial perfusion imaging (MPI) with millions of doses administered annually in the US. In November 2013, the US Food and Drug Administration (FDA) issued a Drug Safety Communication warning health care professionals of the rare but serious risk of heart attack and death with use of either regadenoson or adenosine. ...

Serious complications associated with regadenoson administration for myocardial perfusion imaging

The Editorial by Hage and Iskandrian regarding ‘‘Serious complications associated with regadenoson administration for myocardial perfusion imaging: A commentary’’ (September/October 2014 issue) includes a table as a guide for serious complications associated with regadenoson administration. In the table, the authors reported whether or not each listed event occurs with exercise and/or adenosine...

Detection of obstructive coronary artery disease using regadenoson stress and 82Rb PET/CT myocardial perfusion imaging.

UNLABELLED Our objective was to study the diagnostic performance of regadenoson (82)Rb myocardial perfusion PET imaging to detect obstructive coronary artery disease (CAD). METHODS We studied 134 patients (mean age, 63 ± 12 y; mean body mass index, 31 ± 9 kg/m(2)) without known CAD (96 with coronary angiography and 38 with low pretest likelihood of CAD). Stress left ventricular ejection fract...
