diastolic heart failure

Diastolic heart failure is a condition in which the heart’s pumping chambers (ventricles) become thickened, grow stiff and cannot relax enough to adequately fill the ventricles with blood. The fluid then backs up into organs and causes swelling or edema, especially in feet and ankles. It also causes congestion, even though the heart's pumping function is normal. Diastolic heart failure is caused by conditions such as acute ischemia, systolic hypertension with enlargement of the left ventricular muscle, restrictive cardiomyopathy and hypertrophic cardiomyopathy
