Heart failure is a condition in which the heart is unable to pump an adequate supply of blood to the body’s tissues. It is also known as:
Congestive heart failure
Congestive cardiac failure
Heart failure deprives the main body organs and tissues of oxygen and nutrients. As a result, the organs and tissues may not function properly. This can also lead to oedema, which is the build-up of fluids in the tissues.
Types of heart failure
There are different types of heart failure:
Left-sided heart failure, in which fluid may back up in the lungs and cause shortness of breath.
Right-sided heart failure, in which fluid may back up into your abdomen, legs and feet, causing swelling.
Systolic heart failure, which results when the left ventricle is unable to contract sufficiently.
Diastolic heart failure, which results when the left ventricle is unable to relax or fill fully.
Heart failure is a chronic condition with serious consequences. It affects your general well-being, including your mental, physical, and social status. The prevalence of heart failure increases with age.
Although there is no cure for heart failure, a combination of lifestyle changes, medications and sometimes surgery can help to manage and treat this condition.
What are the symptoms of heart failure?
If you are suffering from heart failure, you may experience any of the following symptoms:
Sudden, severe shortness of breath with coughing up of pink, foamy mucous
What causes heart failure?
Heart failure can be caused by heart disease and other conditions that affect the heart’s ability to pump blood effectively. Common causes include:
Cardiomyopathy, a disease that causes the heart muscle to weaken. Coronary heart disease and other heart diseases can lead to cardiomyopathy.
Coronary heart disease, which is the hardening of arteries supplying blood to the heart due to the build-up of fatty deposits in the walls of the arteries. This restricts the heart’s ability to pump blood. It is one of the most common causes of heart failure.
