What Causes Congestive Heart Failure?

Table of Contents

Congestive heart failure is one of the most important chronic diseases worldwide, and patients with it face many physical and mental stresses that lead to a decrease in their quality of life.

The heart consists of four chambers. Deoxygenated blood enters the upper right cavity (right atrium) from the veins (asteroids) and flows into the lower cavity (right ventricle) with the contraction of the atrium. Then, with the contraction of the right ventricle, blood is pumped to the lungs.

Blood containing oxygen from the lungs enters the left upper chamber (left atrium) and flows into the lower chamber (left ventricle) with the contraction of the atrium. Then, as the left ventricle contracts, blood is pumped through the arteries (arteries) throughout the body.

The structural cause of congestive heart failure is that in people with heart failure, one or both ventricles do not empty completely, and the remaining blood in the heart increases the pressure in the atria (upper cavities) and nearby veins. 

This volume of blood can also affect the kidneys and lungs so that it disrupts their function and leads to the accumulation of fluids (edema) in the lungs, abdominal organs and legs.

Also, in some patients with congestive heart failure, pumping blood from the ventricles is not a problem, but there is a problem in the relaxation of the ventricles (diastole). When the heart is not pumping, it may stiffen and not relax. 

This condition can cause blood accumulation in the ventricles and pressure on the heart.

Causes of congestive heart failure

Congestive heart failure occurs under various conditions and factors in people. Among the causes of congestive heart failure, the following sources can be mentioned:

  • High blood pressure ( fire inside )

    When your blood pressure is higher than normal, it can lead to congestive heart failure. High blood pressure is one of the most important causes of congestive heart failure. 

When the blood pressure is high, the heart has to use more energy to pump blood, and this causes it to fail over time.

Various factors can lead to high blood pressure symptoms in people. If you have high blood pressure, you need to take your medications on time and get regular checkups to avoid congestive heart failure.

  • Coronary artery disease

    Cholesterol and other fats can block the heart’s coronary arteries (the small arteries that supply blood to the heart). These factors make these arteries narrow and cause congestive heart failure in patients. 

When the arteries are blocked, the blood flow to the heart is reduced, and as a result, parts of the heart muscle are deprived of getting enough oxygen. This causes the heart to not work as it should. Spasms of the coronary arteries of the heart should also not be ignored.

  • Heart valve disease

    The valves of the heart are responsible for the transfer of blood to the heart. Heart valve disorders, including narrowing of the valves or their failure, cause problems in blood transfer to the heart and blood pumping. 

If these valves are narrower than normal, blood flow becomes more difficult, and the pressure in the heart muscle increases. If they expand too much, like the hypertensive factor, they put pressure on the heart and again cause congestive heart failure.

  • Congenital heart disease

    Having some congenital defects, such as defective valves or abnormal connections between the heart valves, are among the things that can cause problems with the heart’s function and eventually cause congestive heart failure.

Of course, there are many types of congenital heart diseases, and for this reason, there are many congenital heart defects. Imagine a collection that is partially defective or out of order. 

Undoubtedly, in this case, the rest of the members are forced to compensate for the lack of the incomplete member and are under pressure.

Congenital heart failure usually doesn’t show itself early on, and symptoms appear years later when the child goes to school, plays sports, or even becomes active as an adult.


  • Idiopathic cardiomyopathy

    Cardiomyopathy, or heart muscle damage, can have many causes, including various diseases, infections, alcohol abuse, and the toxic effects of drugs such as cocaine and some chemotherapy drugs. Genetic factors can also play a role in this disease.

The cause of cardiomyopathy itself is divided into three types:

Dilated cardiomyopathy (Dilated cardiomyopathy): the size of the heart chambers, along with the failure of the heart’s contractile function.

Hypertrophic Cardiomyopathy (Hypertrophic Cardiomyopathy): Excessive growth, resulting in thickening of the heart muscle.

and restrictive cardiomyopathy (Cardiomyopathy): reducing the flexibility of the heart muscle

A person suffering from this disease is usually characterized by the enlargement of the heart muscle. 

When the left ventricle of the heart enlarges to compensate for its weak contractions, in this disease, due to heart muscle involvement and disease, the heart cannot provide enough blood flow to the body, and the patient suffers from congestive heart failure symptoms.

  • myocarditis

    Myocarditis is an inflammation of the heart muscle, which is caused by certain viruses and even multiple infections and can be one of the causes of congestive heart failure. According to statistics, half to three and a half per cent of hospitalizations due to congestive heart failure are caused by myocarditis.

  • Abnormal heart rhythm (cardiac arrhythmia)

    Cardiac arrhythmia usually occurs due to improper functioning of the electrical messages that coordinate the heart rate, which slows down or increases the heart rate and causes it to become irregular. Arrhythmia of the heart causes problems in the function of this organ, causes pressure on the heart muscle and finally causes congestive heart failure.

  • Other chronic diseases and complications

    Other chronic diseases that can damage the heart and lead to congestive heart failure include the following:

    • diabetes
    • HIV
    • hyperthyroidism
    • Hypothyroidism
    • high blood iron in the body (hemochromatosis)
    • Deposition of amyloid proteins of organs and tissues (amyloidosis)
    • Viruses and certain infections
    • Alcohol abuse
    • Taking certain drugs such as cocaine or drugs used for chemotherapy
    • Anemia
    • Having a history of heart attack
    • Metabolic diseases
    • smoking
    • Overweight or obesity
    • Etc…

Risk factors of congestive heart failure

What makes heart failure worse?

In addition to the causes of congestive heart failure, there are also some factors that can increase the risk of contracting this disease or cause its development. These factors or the so-called risk factors are:

Complications of congestive heart failure

The heart is one of the most important organs of the body. When the function of the heart is disturbed, other organs and organs also have problems over time and show complications. The most common complications of congestive heart failure can include the following:

  • Renal failures

    Congestive heart failure can lead to kidney failure in patients by reducing the blood flow to the kidneys, and even in more advanced stages, it can force them to undergo dialysis.

  • Liver failures

    Part of the trapped fluids in the body, which occurs due to the lack of blood pumping by the heart, collects in the livers. This fluid accumulation can lead to liver injury and liver diseases in patients with congestive heart failure.

  • Heart valve problems

    Sometimes, congestive heart failure causes the cavities of the heart to enlarge or the pressure inside them to increase. Over time, this causes the valves to be damaged and the person to suffer from valvular heart disease.

What are the three main causes of heart failure?

The three main causes of congestive heart failure are:

  1.  Coronary artery disease: This is the most common cause of heart failure.
  2. High blood pressure: High blood pressure (hypertension) is a leading cause of heart failure.
  3. Heart valve disease


Congestive heart failure, as explained in detail earlier, is a chronic and progressive disease, while the cause and origin of its occurrence is the presence and lack of control of other diseases explained in this article.

Therefore, although the treatment of this disease may be very difficult or even impossible in some cases, by knowing the root causes and managing the symptoms of its causes, you can prevent it from happening.
