Heart failure is the inability of the heart to pump blood throughout the body. Risk of congestive heart failure (CHF) will increase in the elderly due to ventricular function due to aging. CHF can become chronic if accompanied by diseases such as: hypertension, heart valve disease, cardiopathy, and others. Congestive heart failure (CHF) can also become an acute condition and develop suddenly in myocardial infarction. (Kasron, 2012)
Activity intolerance is when a patient makes a movement. For normal people, walking two or three meters does not feel tired, but for patients who experience activity intolerance, move or walk just a little the breath is panting, tired. Because the body is unable to produce enough energy to move. So, any disease that keeps the supply of nutrients and O2 from being blocked or disconnected, in other words interferes with the formation of energy in the body, can cause a body response in the form of activity intolerance. The heart is in charge of pumping blood throughout the body, when the heart experiences interference, the blood that carries O2 and nutrients becomes reduced, so that energy production becomes reduced. (Prihanto, Robert, 2007)
The purpose of nursing action for patients is to overcome the patient's problem in activity intolerance to be able to move again, with the outcome criteria: patients can show tolerance for activities that can be done, vital signs within normal limits, especially blood pressure whose normal values are 110/70 to 130 / 90 mmHg and respiration whose normal value is 12-20 times / minute), there is no dyspnea after activity, there is no fatigue.
The results of the study from Budiyarti (2013) prove that home based exercise training can be applied as one form of nursing intervention for patients with heart failure with nursing problems, intolerance to activity, duration and frequency of home based exercise training performed according to the patient's condition and activity tolerance level.
Research by Halimuddin (2010) proves that after the application of the light intensity client's model of exercise and light intensity training to blood pressure, differences in mean systolic and diastolic blood pressure were obtained before and after intervention.
Heart failure can be treated with general measures to decreases the initial burden of cardiac work and selective manipulation of the three main determinants of myocardial function, both alone and in combination from: decreased preload by limiting salt intake in food by reducing fluid retention, increasing contractility with inotropic drugs, afterload reduction with two compensatory responses to heart failure (sympathetic nervous system activation and renin-angiotensin-aldesterone system) (Asikin, 2016).
