AoB, aortic banding; MAP, mean arterial pressure measured in the descending aorta; LVSP, left ventricular systolic pressure measured proximal to the band; SAP, systolic artery pressure measured in the descending aorta; BW, body weight; LVW, left ventricular weight; HR, heart rate; CO, cardiac output; PAP, pulmonary arterial pressure. Those values were obtained under anesthesia at the end of follow-up. Values are mean ± SEM; ∗P < 0.05 vs. Sham.
