Chronic Heart Failure Chronic heart failure (CHF) is a
potentially lethal condition where the heart cannot pump a
sufficient amount of blood, which can then cause blood to
accumulate in the vessels leading to the heart and can cause
congestion or accumulation of fluid in various parts of the
body. The precise part of the heart that fails impacts the
damage caused. For instance, if the left chambers of the heart
fail, blood backs up into the lungs, causing lung congestion. If
the right chambers of the heart fail, blood backs up into the
legs and the liver, causing congestion and swelling, called
edema. CHF is usually accompanied by an enlargement in the size
of the heart. Symptoms of heart failure can be mild or moderate,
including shortness of breath, fatigue, and weakness, especially
with exercise. CHF can also cause heart palpitations and
dizziness. Treatment of CHF can be very difficult and involves
rest, proper diet, and a variety of medications. The Social
