We assessed transmurally the coronary autoregulatory response to elevated perfusion pressure in 85 anesthetized, open-chest dogs. Steady state and transient flow distributions were measured with 9 ± 1 /im radioactive microspheres. Steady state distributions of myocardial blood flow were uniform transmurally (P > 0.05) at perfusion pressures of 103 ± 1 (n = 81) and 146 ± 2 (n = 34) mm Hg, whereas Endo:Epi ratios of 1.26 ± 0.05 and 1.51 ± 0.07 at perfusion pressures of 194 ± 1 (n = 60) and 221… CONTINUE READING
