Congestive heart failure, also known as heart failure, is a long-term condition in which the heart muscle doesnt pump blood as well as it should. As a result, blood often backs up and fluid can build up in the lungs, legs, and feet. The term "congestive" refers to the resulting buildup of fluid in the body. Heart failure can be caused by a weakened, damaged, or stiff heart. Some of the common causes of heart failure include:

• Coronary artery disease
• High blood pressure
• Heart attack
• Heart valve problems
• Infections
• Autoimmune diseases
• Chemotherapy
• Sedentary lifestyle
• Poor diet
• Smoking
• Being overweight or obese
• Stress

Symptoms of heart failure may develop slowly or start suddenly. They may include:

• Shortness of breath with activity or when lying down
• Fatigue or weakness even after rest
• Coughing
• Swelling and weight gain from fluid in the ankles, lower legs, or abdomen (belly)
• Difficulty sleeping when lying flat
• Nausea and loss of appetite
• Swelling in the veins of your neck
• Needing to urinate (pee) often

Heart failure can be diagnosed through a physical exam, medical history, and tests such as an electrocardiogram (ECG), echocardiogram, and blood tests. Treatment for heart failure may involve lifestyle changes, medications, and in severe cases, surgery or a heart transplant. It is important to manage the underlying conditions that contribute to heart failure to prevent its development or progression.
