were compared with results from eight control dogs with an LV weight/body weight ratio of 4.9±0.2. At rest, LV systolic and end-diastolic pressures were significantly greater (p<0.01), and mean arterial pressure was significantly less (p<0.05) in LVH dogs. Mean myocardial blood flow (control dogs, 0.98+±0.11 ml/min/g; LVH dogs, 1.16±0.06 ml/min/g) and the transmural blood flow distribution at baseline, as assessed by endocardial/epicardial blood flow ratio (control, 1.35+±0.12; LVH, 1.21+0.09), were similar in the two groups.
