What are the symptoms of congestive heart failure?

There are many symptoms of congestive heart failure:

  • The most common symptom is shortness of breath or difficulty breathing (dyspnea). It's caused by pulmonary edema. There are many different types of dyspnea. You could have shortness of breath only with exercise, but as the disease progresses, it will take less exertion to produce dyspnea.
  • There is also shortness of breath while at rest and while when lying down (orthopnea). While lying down, blood from the elevated legs might return to the heart and cause pulmonary edema. This symptom is relieved by sitting up. Many people try sleeping on several pillows or in a chair to alleviate this. Sometimes there is intermittent shortness of breath at night (paroxysmal nocturnal dyspnea). Pulmonary edema causes this, as does depression of breathing during the sleep state.
  • Coughing.
  • Edema occurs most often in the legs. This usually increases during the day simply due to gravity increasing the amount and pressure of blood in the veins, pushing more fluid out. It improves when the legs are elevated. Diuretics (fluid pills) can eliminate the excess fluid. Edema occurs in many other areas, such as the abdominal cavity, the chest cavity, the pericardium, and in the stomach and intestines, which causes nausea and loss of appetite.
  • Fluid retention often results in weight gain.
  • A common symptom is fatigue, which may be related to reduced blood flow to organs and muscles. Sometimes CHF reduces blood flow to the brain and causes confusion, especially in the elderly.
  • Chest pain is a symptom of angina and heart attacks, both causes of CHF.
  • A severe and abrupt onset or worsening of CHF is Acute pulmonary edema, which can lead to dangerously low levels of oxygen in the blood. This can be life threatening. Symptoms include severe shortness of breath, a cough that can be blood tinged (hemoptysis), profuse sweating and anxiety. Acute pulmonary edema requires immediate treatment.

  1. Cough (typically non-productive) with or without wheezing
  2. Fatigue
  3. Shortness of breath at rest or worse on exertion
  4. Palpitations
  5. Sudden weight gain
  6. Edema (may see lower extremity swelling)
  7. Increase abdominal girth over a short period of time
  8. Chest pain or chest pressure
  9. Inability to sleep flat at night. May require more pillows to elevate head to sleep comfortably (called orthopnea)
  10. Waking up suddenly in the middle of the night gasping for air (called "PND" or paroxysmal nocturnal dyspnea)
  11. Confusion or irritability
