About Heart Failure

More than 14 million people in Europe(3) and five million U.S. residents(4) have heart failure (HF), a serious chronic condition in which the heart cannot effectively pump blood. Hospitalizations in the United States related to HF account for 75 percent of the $46 billion spent each year on the care of HF patients, according to the American Heart Association.(5) The majority of patients hospitalized for worsening HF, about 1 million U.S. residents annually, have edema or excess body fluid.
