Diastolic heart failure is also known as heart failure with preserved systolic function or heart failure with normal ejection fraction. Diastolic heart failure can occur alone or with systolic heart failure. Approximately 550,000 individuals in the United States are diagnosed with heart failure and half of them have diastolic heart failure. Diastolic heart failure is mainly common in elderly people with age of 65 or older. Also, it is mainly diagnosed in women than men (Huether and McCance 2012). The major causes of diastolic heart failure are hypertension-induced myocardial hypertrophy and myocardial ischemia-induced ventricular transformation (coronary artery disease). Hypertrophy and ischemia cause a decreased ability of the myocytes to actively pump calcium from the cytosol, resulting in impaired relaxation. Some of the other causes are aortic valvular disease and cardiomyopathies. Diabetes can also lead to diastolic heart failure (Huether and McCune 2012). Other risk factors for this disease are chronic kidney disease, obstructive sleep apnea, and older age. There are two types of the heart failure: systolic heart failure and diastolic heart failure. In systolic heart failure, the left ventricle has difficulty contracting and ejecting blood into the circulation, which causes reduced left ventricular fraction. On the other hand, diastolic heart failure has a slow and delayed relaxation and increased chamber rigidity, which then causes inadequate filling of blood and
