Figure 7From: Assessment of global myocardial perfusion reserve using cardiovascular magnetic resonance of coronary sinus flow at 3 TeslaAbsolute coronary sinus flow during regadenoson stress protocol. Absolute coronary sinus flow (±SEM) measured at three time-points (pre-stress, peak stress, post stress). In patients receiving aminophylline (panel a) and in patients not receiving aminophylline (panel b) demonstrates significant residual hyperemia in the absence of aminophylline.Back to article page
