Figure 1

Effect of cardiac work on coronary blood flow and oxygen consumption in awake canines. Exercise was conducted on an 11° incline treadmill with rates approaching 16km/min. A) Represents the oxygen usage as a function of coronary flow over the exercise range. B) Represents the relationship between coronary oxygen utilization from using the left main or circumflex artery flow values and left ventricular work. C) Represents the oxygen extraction values as a function of running speed. All data adapted from Khouri et al 5.
