Congestive heart failure (CHF) is a condition in which the heart fails
to pump enough blood to the body. As the pumping slows, blood can
accumulate in the body, causing congestion in areas such as the arms,
legs, lungs, and liver. And this can reduce the flow of vital oxygen and
nutrients to various organs.
Congestive heart failure is the
leading cause of hospitalization for patients over the age of 65—and it
often goes undiagnosed and untreated.
