The Full form of CHF is Congestive Heart Failure. CHF is the inability of the heart to keep up with the demands on it, with failure of the heart to pump blood with normal efficiency. When this occurs, the heart is unable to provide adequate blood flow to organs, such as the brain, liver, and kidneys. CHF may be due to failure of the left or right ventricle, or both. The symptoms of CHF can include fatigue, dyspnea (shortness of breath), asthma due to the heart (cardiac asthma), pooling of blood (stasis) in the general body (systemic) circulation or in the liver’s (portal) circulation, diminished exercise capacity, edema (swelling), cyanosis (blueness or duskiness), and enlargement (hypertrophy) of the heart. The many causes of CHF include coronary artery disease leading to heart attacks and heart muscle (myocardium) weakness; primary heart muscle weakness from viral infections or toxins, such as prolonged alcohol exposure; heart valve disease causing heart muscle weakness due to too much leaking of blood or causing heart muscle stiffness from a blocked valve; hyperthyroidism; and high blood pressure. The treatment of Congestive Heart Failure (CHF) can include lifestyle modifications, addressing potentially reversible factors, medications and mechanical therapies and heart transplant.
