Heart Failure is a serious condition in which your heart fails to pump blood sufficient enough to meet your body’s oxygen needs. It is also called as congestive cardiac failure, right side heart failure, left side heart failure or cor pulmonale. Heart Failure occurs when the heart cannot relax properly to fill in enough blood (right sided heart failure) or cannot contract properly to pump out enough oxygen rich blood (left sided heart failure) or due to a combination of both problems (congestive heart failure).
Right sided heart failure is a result of high blood pressure in pulmonary arteries (arteries taking blood from heart to lung) is called cor pulmonale.
As heart becomes weaker, toxins build up in the body, which worsen the symptoms.
Currently, there is no cure for heart failure. However, it can be managed by medications and life style changes to allow you to lead a normal and active life.
Heart failure is treated by cardiologists. However your regular doctor can help in diagnosis, and in managing your medication and treatment.
What Happens in Heart Failure
Heart has four chambers, two upper (right and left atrium) and two lower (right and left ventricle).
In normal condition the right atrium receives oxygen poor blood from the body, pushes it to right ventricle. From the right ventricle the blood is pushed to lungs through pulmonary arteries for purification. Oxygen rich blood from the lungs fills the left atrium. This blood is pushed to the left ventricle which contracts to push the oxygen rich blood to the rest of the body.
In left side heart failure, the heart fails to contract or relax properly. When the heart does not contract properly, less oxygen rich blood is pushed out to the body. The excess blood accumulates in the left ventricle and atrium. This creates a backward pressure and pushes the blood back into the lung. Thus fluid accumulates in the lung.
In right side heart failure, the right atrium and ventricle fail to relax properly. Hence they are unable to take the oxygen poor blood from rest of the body. This causes a backward pressure such that fluid accumulates in the body, especially in feet, ankle, legs and abdomen.
Usually both right and left sided heart failures are present at the same time. However one may be more prominent than the other.
