The lungs are significantly affected as a backup of blood in the pulmonary veins leads to pulmonary hypertension. This condition also affects the function of numerous organs and tissues. Heart failure is usually the consequence of ischemic and hypertensive heart disease. There are four types of heart failure, based on the cause and location of myocardium damage. The Functional Classification of Heart Failure, based on the client's tolerance to physical activities, is used to help determine the progression of the disease.1,2 Treatment is focused on the primary cause of the condition, using diet, medication, and exercise to manage it. Some clients will have undergone heart valve replacement, coronary artery bypass grafting, or heart reduction surgery. Clients experience significant dyspnea and fatigue with physical activities due to the heart's inability to adequately supply blood to extremities, which in turn leads to atrophy of extremity muscles.1
