What is congestive heart failure?

Congestive heart failure (CHF) happens when the heart’s weak pumping action causes a buildup of fluid called congestion in the lungs and other body tissues.  Those at risk for developing CHF have the following:

  • Coronary heart disease
  • Cardiomyopathy
  • Previous heart attacks
  • High blood pressure
  • Irregular heartbeat
  • Congenital heart defects
  • Heart valve disease
  • Alcohol and drug abuse
