Congestive Heart Failure
Congestive heart failure (pronounced: kənˈjestiv hɑːrt ˈfeɪljər), often referred to as CHF, is a chronic progressive condition that affects the pumping power of your heart muscles.
Etymology
The term "congestive heart failure" comes from the blood flow slowing down and backing up into the lungs, liver, abdomen, and lower extremities causing congestion in the body.
Definition
Congestive heart failure is a type of heart failure which requires seeking timely medical attention, although it often gradually develops over time. The condition occurs when the heart is unable to pump an adequate amount of blood, leading to an accumulation of fluid in the lungs, liver, abdomen, or lower extremities.

Symptoms of congestive heart failure can include:
- Shortness of breath
- Fatigue
- Swollen legs

- Increased need to urinate at night
- Swelling of your abdomen (ascites)
- Very rapid weight gain from fluid retention
- Lack of appetite and nausea
- Difficulty concentrating or decreased alertness
- Sudden, severe shortness of breath and coughing up pink, foamy mucus
Causes
Congestive heart failure is caused by many conditions that damage the heart muscle, including:
- Coronary artery disease
- High blood pressure
- Faulty heart valves
- Damage from a heart attack
- Myocarditis
- Certain medications
- Irregular heart rhythms (arrhythmias)
Treatment
Treatment for congestive heart failure often involves:
- Taking medications
- Reducing sodium in your diet
- Managing stress
- Regular physical activity
- Keeping a healthy weight
- Limiting alcohol and caffeine
