Therefore the HF concept has been broadened thus including, on one end of the spectrum; patients with volume overload and reduced ejection fraction (EF) and on the other end asymptomatic patients with important systolic and diastolic derrangements.In order to understand the benefit exerted by some...
prognosis and drug responsiveness, and whether sex-specific exercise cut-offs are needed for an accurate HFpEF diagnosis. The currently used diagnostic tools for HFpEF all advise additional exercise testing combined with echocardiography or right heart catheterization when diastolic function findings at rest...

Diastolic and systolic HF may have certain similar pathophysiologic processes in common, but there are also distinct differences in myocardial structure and function. Most treatment strategies for diastolic HF strive to alleviate signs and symptoms or prevent exacerbating factors rather than alter the ...
Methods using a model integrating the roles of aging, estrogen depletion and metabolic syndrome on promoting diastolic dysfunction and myocardial fibrosis. Female, 18-month-old, Fischer 344 rats were allocated into an ovariectomy (OVX), ovariectomy+epi (OVE), ovariectomy+fructose (OVF) and ...
However, it is possible for patients with normal ejection fraction to haveHF, and this form of the disease, HF with preserved ejection fraction, orHFpEF, is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. ...

Approximately half of the patients with heart failure have preserved left ventrical (LV) systolic function and usually have some degree of diastolic dysfunction. Patients with reduced or preserved systolic function may have similar symptoms and it may be difficult to distinguish clinically between the ...
Diastolic function assessment using echocardiography has been a cornerstone in the work-up and is as important as systolic functional assessment. There has been increased awareness to the potential utility of cardiac magnetic resonance (CMR) imaging over the past decade as a promising, radiation-free...
