Evidence ef compensatory preload adjustment on early filling phase in patients with stable angina pectoris and good left ventricular systolic function

The normal mitral flow pattern seen in our patients with stable angina and good systolic function is related to an increase in atria1 pressure; this increase maintains normal stroke volume despite impaired relaxation and a moderate increase in the minimum LV diastolic pressure (a finding that confirms a computer-simulation hypothesis by Thomas et al13).
