Figure 2 Invasive hemodynamic parameters of global systolic and diastolic function at peak dobutamine (Dob) were similar with and without stenosis (A). Regional myocardial blood flow (RMBF) at peak dobutamine was lower with compared to without stenosis (B, left panel). Peak change in systolic strain rate (sSR) and time to regional lengthening (T_RL) at peak dobutamine was significantly blunted with compared to without stenosis (B, middle and right panels, respectively). *p < 0.01 between baseline and dobutamine + stenosis; p < 0.01 between baseline and dobutamine; p < 0.01 between dobutamine and dobutamine + stenosis. SE = strain echocardiography.
