Effects of alterations in coronary tone and myocardial oxygen consumption on coronary pressure–flow autoregulation. a Coronary blood flow increased at a given CPP as vasomotor tone was decreased: control (n = 7) > hemodilution (n = 6) > hemodilution + dobutamine (n = 5). Relative to untreated control swine, the slope of flow–pressure relationship within the autoregulatory range (CPP 120–60 mmHg) was significantly increased by hemodilution (P = 0.03) and hemodilution + dobutamine (P < 0.001). b Average coronary vascular resistance was significantly reduced by hemodilution (P < 0.001) and hemodilution + dobutamine (P < 0.001)
