Cardiology Clinics, 2000
Modeling methods have been employed to further characterize the physical and physiologic processes of filling and diastolic function. They have led to more detailed understanding of the effect of alteration of physiologic parameters on the Doppler E-wave contour as well as pulmonary vein flow.

Cardiology in Review, 1998
The pumping function of the left ventricle depends both on its ability to empty and its capacity to fill at a low pressure. Diastolic dysfunction occurs when filling of the left ventricle necessary to produce an adequate cardiac output requires an elevated pulmonary venous pressure.

Diastolic Ventricular Interaction and Ventricular Diastolic Filling
Heart Failure Reviews, 2000Because the ventricles share a common septum, the filling of one may influence the compliance of the other, a phenomenon known as direct diastolic ventricular interaction (DVI). This interaction is markedly enhanced when the force exerted by the surrounding pericardium is raised (pericardial constraint). In health, in the resting state, we operate near

Early diastolic overinflation in diastolic mitral regurgitation
Journal of Echocardiography, 2012An 81-year-old man presented with exertional dyspnea at our hospital. An electrocardiogram was recorded, which showed 2:1 atrioventricular (AV) block. Transthoracic 2-dimensional echocardiography showed that the left ventricular (LV) wall thickness and wall motion were normal. Color Doppler echocardiography showed no significant valvular heart disease.

Current Treatment Options in Cardiovascular Medicine, 2004
Heart failure is a leading cause of hospital admissions in North America. Approximately half of patients with symptoms of heart failure have normal or minimally impaired systolic function and are therefore diagnosed, by exclusion, with diastolic dysfunction. The therapy of diastolic dysfunction to date is largely unsatisfactory.

Although the annual mortality rate for diastolic heart failure is better than that for systolic heart failure, it is still greater than that for age-matched controls. Five-year mortality rates are about 50% for patients with systolic heart failure and are about 25% for patients with diastolic heart failure.

Diastolic Dysfunction and Diastolic Heart Failure
2000It has been shown that heart failure frequently occurs in the absence of left ventricular (LV) systolic dysfunction, and diastolic dysfunction is considered to be the underlying cause for this phenotype of heart failure: isolated diastolic heart failure.

Left Ventricular Diastolic Dysfunction and Diastolic Heart Failure
Annual Review of Medicine, 2004Thirty to fifty percent of patients presenting with signs and symptoms of heart failure have a normal left ventricular (LV) systolic ejection fraction. The clinical examination cannot distinguish these patients (diastolic heart failure) from those with a depressed ejection fraction (systolic heart failure), but echocardiography can.

Cardiology Clinics, 2000
It is now recognized that a sizable portion of patients who exhibit symptoms of congestive heart failure have relatively well-preserved systolic function, but have significantly elevated LV filling pressures. This syndrome, termed "diastolic heart failure," is associated with various conditions such as aging, anatomic abnormalities, hypertension ...

Hypertension and Diastolic Function
Drugs, 1993Abnormalities in left ventricular (LV) diastolic function in the presence of normal LV systolic performance is one of the earliest cardiac manifestations of systemic hypertension. Alterations in diastolic filling indices have been observed more clearly in patients with LV hypertrophy, although it is evident that these filling abnormalities may be ...
