Definition of Diastolic Dysfunction and HF Ø Diastolic HF is a clinical syndrome characterized by the symptoms and signs of HF, a preserved EF and abnormal diastolic function. Ø Diastolic dysfunction occurs when the time period during which the myocardium loses its ability to generate force and shorten and returns to an unstressed length and force, is prolonged, slowed or incomplete. Ø Systolic and diastolic HF occurs when patients have a modest decrease in EF and a modest increase in end-diastolic volume but a marked increase in end-diastolic pressure and a diastolic pressure-volume relationship that reflects decreased chamber compliance.
