Congestive Heart Failure
Congestive Heart Failure (CHF) is a potentially
lethal condition in which the heart cannot pump out all of the
blood that enters it, which causes blood to accumulate in the
vessels leading to the heart, and congestion or accumulation of
fluid in various parts of the body. CHF is accompanied by an enlargement
in the size of the heart.
If the left chambers of the heart fail, then blood
backs up into the lungs, causing congestion there. If the right
chambers of the heart fail, then blood backs up into the legs
and the liver, causing congestion and swelling (called edema).
Often, both sides fail simultaneously. Most forms of heart disease,
including valvular and pericardial disease, eventually lead to
congestive heart failure. Some forms of congestive heart disease
damage the blood vessels causing a condition known as cor pulmonale.
Causes of congestive heart failure include past
heart attack, which can lead to the development of scar tissue
that interferes with heart muscle function; poorly controlled
hypertension, which causes high blood pressure; coronary artery
disease, in which arteries that supply blood to the heart muscle
are narrowed; cardiomyopathy, endocarditis, and myocarditis, which
are conditions in which the heart muscle, valves, or surface tissue
becomes or inflamed. Congenital heart defects and heart valve
disease due can also cause congestive heart failure.
