Ventricular performance after onset of renal hypertension.
1. In renal hypertensive dogs, the slope of the relation between either stroke volume or cardiac output and end-diastolic pressure is shifted to the right of the normal curves. 2. The maximum to which stroke volume or cardiac output can be raised during loading is significantly less. These changes in cardiac performance appear to be unrelated to the severity of hypertension.
