Background— Reductions in heart rate (HR) with β-blocker therapy have been associated with improvements in ejection fraction (EF). However, the relative contributions of HR reduction, positive inotropism, afterload reduction, and reverse remodelin

Background: Although echo Doppler recordings of mitral inflow patterns are often employed clinically to identify “diastolic dysfunction,” abnormal flow profiles may be seen in a diverse set of disorders in which the specific physiologic determina

Objectives The purpose of this study was to evaluate left ventricular (LV) size and structure in elderly subjects with hypertension (HTN) and heart failure who have a normal ejection fraction (HFNEF) in a large population-based sample. Background The

The incidence and prevalence of heart failure are increasing as the population ages. Epidemiologic studies demonstrate that more than half of heart failure patients have a normal ejection fraction. The pathophysiology of this disorder is not complete

Patients with diastolic heart failure are thought to have a normal or small ventricle with impaired ventricular filling that requires increased filling pressure to maintain normal stroke volume. In this study we test the hypothesis that patients with

Although heart failure with a normal ejection fraction (HFNEF) is a clinically heterogeneous syndrome, a single pathophysiologic mechanism, diastolic dysfunction, is often ascribed to explain this condition. In view of the clinical heterogeneity of t

Background: Measures of ventricular performance, such as the ejection fraction, assume that myocardium is noncompressible and does not change volume significantly from end diastole to end systole. Although this principle is widely accepted as true, l

Quantitative ventriculography by freehand 3-dimensional (3D) echocardiography with an acoustic spatial locator has been proven to provide highly accurate reproducible measurements of left ventricular volume, mass, and function. It has been shown to b

A long retention interval tends to result in the poor retention known as forgetting. A high subjective similarity between stimuli frequently produces their poor retention. Thus, a long retention interval may increase the subjective similarity between
