Understanding heart failure

The heart is the major organ of the circulatory system. It is a muscle that pumps blood throughout the body by rhythmic, involuntary contractions. But what happens when it is no longer up to this important job?


Heart failure (HF) occurs when the heart becomes unable to pump blood normally and efficiently, depriving the body of the oxygen it needs to function properly. Every year in industrialized countries, this condition strikes one to five people out of 1,000, regardless of age. Most people suffering from HF, however, are over the age of 70.


HF rarely comes alone. In fact, it is often caused by other serious health problems, such as:

An unhealthy lifestyle can also increase a person’s risk for HF. The excessive use of alcohol and drugs, smoking and obesity are all factors that can impair a person’s heart. 


When the heart can no longer adequately pump blood throughout the body, many symptoms can occur:

  • Fatigue or weakness
  • Shortness of breath
  • Wheezing
  • Coughing at night (due to a build-up of fluids in the lungs)
  • Swelling in the ankles and legs
  • Sudden weight gain
  • Loss or change in appetite
  • Pale skin and cold extremities
  • Intolerance to cold
  • Constipation
  • Need to urinate at night
  • Abdominal pain


Heart failure normally requires changing your lifestyle and taking medications. Treatment should always be conducted under the supervision of a physician. Patients are normally asked to:

  • Decrease their intake of salt to reduce fluid retention
  • Reduce intake of liquids
  • Remain active
  • Wear support hose to decrease swelling of the legs
  • If necessary, adopt a suitable weight loss program

At times, lifestyle changes and medication are not enough. A person with severe heart failure may then require surgery to install a pump or pacemaker.


HF cannot always be prevented. There are, however, several ways to keep a heart physically fit. This includes:
