What is diastolic heart failure?
Less blood pumped with each contraction sets the stage for a type of heart failure that goes by many names: diastolic heart failure, heart failure with normal ejection fraction, heart failure with preserved systolic function, and others. Diastolic heart failure isn’t really new.
What happens to the heart during diastole?
During diastole (die-AS-tuh-lee), the muscle fibers relax and stretch. This lets the four chambers expand and fill with blood as the heart untwists, creating suction that helps pull blood into the ventricles.
What is mild diastolic dysfunction?
Mild diastolic dysfunction occurs when one or both lower chambers of the heart (ventricles) have a little trouble relaxing in between beats because they have become slightly stiff. Usually, this happens in the left ventricle and is typically referred to as grade 1 diastolic dysfunction.
What is Grade 1 diastolic dysfunction?
People with Grade 1 diastolic dysfunction have evidence of abnormal diastolic function, but have not yet developed any symptoms of heart failure. Diastolic dysfunction does not necessarily translate to a diagnosis of heart failure, and preserved ejection fraction means that the percentage is within the normal range, or over 50%. 2

What is the best diuretic for diastolic heart failure?
One large study suggests a potassium sparing diuretic such as spironolactone (Aldactone) may be especially helpful in selected individuals. Scores of other clinical trials investigating possible treatments for diastolic heart failure are ongoing, but solid results are still a ways off.
What does diastolic heart failure look and feel like?
Diastolic heart failure looks and feels just like systolic heart failure. Its hallmarks are shortness of breath with exertion or when lying down; swelling in the legs, ankles, or abdomen; unexplained fatigue; or a bulging jugular vein. The main way to distinguish one type from the other is with an echocardiogram.
