Heart Failure
Heart Failure
Heart failure is a progressive disorder in which damage to the heart causes weakening of the cardiovascular system. It manifests by fluid congestion or inadequate blood flow to tissues. Heart failure progresses by underlying heart injury or inappropriate responses of the body to heart impairment.
Heart failure may result from one or the sum of many causes. It is a progressive disorder that must be managed in regard to not only the state of the heart, but the condition of the circulation, lungs, neuroendocrine system and other organs as well. Furthermore, when other conditions are present (e.g. kidney impairment, hypertension, vascular disease, or diabetes) it can be more of a problem. Finally, the impact it can have on a patient psychologically and socially are important as well.
Heart failure is a cumulative consequence of all insults to the heart over someone's life. It is estimated that nearly 5 million Americans have heart failure. The prevalence of heart failure approximately DOUBLES with each decade of life. As people live longer, the occurrence of heart failure rises, as well as other conditions that complicate its treatment. Even when symptoms are absent or controlled, impaired heart function implies a reduced duration of survival. Fortunately, many factors that can prevent heart failure and improve outcome are known and can be applied at any stage. Heartfailure.org
Symptoms of Heart Failure
Heart failure can be chronic — meaning your condition is ongoing — or acute, meaning your condition has started suddenly.
Chronic heart failure signs and symptoms
- Shortness of breath (dyspnea) when you exert yourself or when you lie down
- Fatigue and weakness
- Swelling (edema) in your legs, ankles and feet
- Rapid or irregular heartbeat
- Reduced ability to exercise
- Persistent cough or wheezing with white or pink blood-tinged phlegm
- Swelling of your abdomen (ascites)
- Sudden weight gain from fluid retention
- Lack of appetite and nausea
- Difficulty concentrating or decreased alertness
Acute heart failure signs and symptoms
- Symptoms similar to those of chronic heart failure, but more severe and start or worsen suddenly
- Sudden fluid buildup
- Rapid or irregular heartbeat (palpitations)
- Sudden, severe shortness of breath and coughing up pink, foamy mucus
- Chest pain, if your heart failure is caused by a heart attack
When to see a doctor
See your doctor if you experience any of the signs or symptoms associated with heart failure. These include:- Chest pain
- Fatigue and weakness
- Rapid or irregular heartbeat
- Shortness of breath (dyspnea) when you exert yourself or when you lie down
- Reduced ability to exercise
- Persistent cough or wheezing with white or pink blood-tinged phlegm
- Swelling in your abdomen, legs, ankles and feet
- Difficulty concentrating or decreased alertness
You may first find out you have heart failure from an emergency room visit after worsening symptoms. Other heart and lung problems can cause symptoms that are similar to heart failure.
If you have a diagnosis of heart failure, and if any of the symptoms suddenly become worse or you develop a new sign or symptom, it may mean that existing heart failure is getting worse or not responding to treatment. Contact your doctor promptly.
