At 4 weeks after coronary artery ligation, hemodynamic variables were monitored using a catheter tip manometer advanced from the right carotid artery via the aortic arch into the left ventricle at the end of the experiment. Data represent means ± SEM. BW, body weight; HW, heart weight; LVW, left ventricular weight; LVEDP, left ventricle end–diastolic pressure; LVESP, left ventricle end–systolic pressure; ±dp/dtmax, maximal rate of increase and decline in left ventricular pressure.
P < 0. 05 vs. sham;
P < 0.05 vs. sham, AMI + saline, and AMI + rAAV–GFP.
