Contractile Behavior of the Left Ventricle in Diastolic Heart Failure With Emphasis on Regional Systolic Function
In diastolic heart failure, the left ventricular (LV) ejection fraction (EF) is normal and there is increased passive stiffness with impaired relaxation of the ventricle, resulting in disturbances in the pattern of filling and elevated diastolic pressure.1–3 The mechanism underlying such failure has been thought to be principally diastolic because LV diastolic function is universally abnormal a...

متن کاملDiastolic heart failure--abnormalities in active relaxation and passive stiffness of the left ventricle.
BACKGROUND Patients with signs and symptoms of heart failure and a normal left ventricular ejection fraction are said to have diastolic heart failure. It has traditionally been thought that the pathophysiological cause of heart failure in these patients is an abnormality in the diastolic properties of the left ventricle; however, this hypothesis remains largely unproven. METHODS We prospectiv...
متن کاملLeft atrial function in diastolic heart failure.
BACKGROUND Abnormalities in left ventricular (LV) structure and function occur in patients with diastolic heart failure (DHF). The reasons for the transition from asymptomatic dysfunction to heart failure need better definition, including noninvasive measurements that can detect the transition. METHODS AND RESULTS In 64 patients undergoing right heart catheterization, simultaneous echocardiog...
