What is congestive heart failure?

What is congestive heart failure? Congestive heart failure is a condition that occurs when the heart muscles in the human body fail to pump blood efficiently. That means your heart is not pumping enough blood to supply your body with the blood and oxygen it needs. But that doesn't mean your heart has stopped working. This means your heart is not working as efficiently as it should. As a result, other parts of your body cannot function properly, which can lead to serious problems later on.

This failure of the heart leads to the accumulation of fluid in other tissues and organs of the body, resulting in symptoms such as fatigue, shortness of breath, and swelling of the feet and ankles. It is more common in individuals and those who have had heart disease for many years. More than 6 million people in the United States currently have congestive heart failure. Most of whom are over 65 years of age.

In simple terms, congestive heart failure is associated with heart failure, i.e. when the ability of the heart to pump blood and deliver oxygen and nutrients to the whole body is reduced to a greater extent than required, we call it heart failure.

Congestive heart failure stages

Congestive heart failure is a serious condition that occurs when the heart in the human body fails to pump blood effectively. The American Heart Association (AHA) and the American College of Cardiology (ACC) divide heart failure into four levels based on the severity of congestive heart failure symptoms and the impact on daily activities. Below is some information about the four stages of congestive heart failure.


This stage of congestive heart failure includes people who are at risk of developing heart failure but have no structural heart abnormalities or symptoms. Risk factors for people at this stage include hypertension, diabetes, coronary vascular disease, obesity, cardiomyopathy, cardiotoxicity, family history of cardiomyopathy, etc. People who smoke, use alcohol, or use illegal drugs are also more likely to develop this problem.


In this stage of congestive heart failure, there is structural damage to the heart but the heart can pump blood efficiently at rest. People in this stage may have no symptoms or may experience symptoms only during physical activity. These symptoms may include shortness of breath, fatigue, or exercise intolerance.

This level of congestive heart failure includes people who have already been diagnosed with heart failure. Individuals at this stage begin to experience symptoms of heart failure regularly. The notable symptoms of this stage are shortness of breath, lower body swelling, leg weakness, fatigue, rapid weight gain, reduced ability to exercise, etc. However, the symptoms are often much more severe.


This level of congestive heart failure includes people who continue to experience severe symptoms despite receiving treatment for the problem. At this level, the heart becomes severely weakened and cannot pump blood effectively. These individuals may require special interventions, such as mechanical ventilation or heart transplantation.

Symptoms of congestive heart failure
