Stress-shortening relations and myocardial blood flow in compensated and failing canine hearts with pressure-overload hypertrophy.

Serial changes in left ventricular (LV) size and function during the adaptation to chronic pressure overload and the transition to pump failure were studied in 16 conscious dogs (aortic bands placed at 8 weeks of age). Echocardiographic data at baseline and at 3, 6, 9, and 12 months after banding re... View More
