Values are means ± SEM. Flow rate = coronary flow rate; dP/dt max = maximum 1st derivative of the change in left ventricular pressure/time; dP/dt min = minimum 1st derivative of the change in left ventricular pressure/time; time to contracture = onset time to ischemic contracture. *Significantly different from FA; p < 0.05; n = 5-8.
