The American Heart Association (2015) defines heart failure as a progressive condition in which the heart is incapable of pumping a sufficient amount of blood to meet the body’s requirement. Heart failure is caused by a structural or functional disorder cardiac condition that decreases the heart’s ability to eject blood (The American Heart Association, 2015; Alpert, Lavie, Agrawal, Aggarwal, & Kumar, 2014). The causes of heart failure include hypertension, arrhythmias, ischemic heart disease, valve disorders, and metabolic disorders (Nicholson, 2014). In addition, obesity has been positively correlated with heart failure, with up to 86% of obese patients being diagnosed with heart failure (Alpert et al., 2014). Heart failure affects approximately 23 million people worldwide and roughly 5.8 people are affected in the United States (Alpert et al., 2014). It is estimated that roughly 40 to 71% of people affected by heart failure have a normal or close to normal left ventricular ejection fraction (Alpert et al., 2014). The prevalence of heart failure increases with age and it is estimated that 6-10% of people over the age of 65 are affected (Kasper et al., 2015). Heart failure is a progressive disorder that is often initiated by an event that damages the heart muscle (Kasper et al., 2015). As a result, the myocardium is unable to contract as it normally would and the heart’s pumping capacity is deteriorated (Kasper et al., 2015). Although, the heart’s pumping capacity is…
