Figure 4 Changes in diastolic LVP-volume relations and changes in LV chamber stiffness at each stage. Top: Representative diastolic LVP-volume relations at baseline, during MI and during MI with DOB all without Aoc. Bottom: Changes in LV chamber stiffness at baseline, during MI and during MI with DOB, with or without Aoc. Data are the mean ± SD. Aoc = aortic constriction; DOB = dobutamine infusion; LV = left ventricle; LVP = left ventricular pressure; MI = myocardial ischemia.
