Diastolic heart failure is a type of heart failure in which the heart’s left ventricle fails to relax and fill with blood properly. This type of heart failure is caused by the inability of the left ventricle to relax and fill with blood during diastole, the period of the heart’s cycle when it is filling with blood. This can lead to a decrease in the amount of blood that is pumped out of the heart, resulting in symptoms such as shortness of breath, fatigue, and swelling in the legs and feet. Treatment for diastolic heart failure typically includes lifestyle changes, medications, and in some cases, surgery.
