What is Heart Failure? An Overview

Heart failure is a condition in which the heart is unable to meet the body's needs, resulting in decreased blood flow, blood retention in veins or lungs (congestion), further weakening of the heart's function, or hardening of the heart. so on.

• Heart failure is caused by insufficient contraction and relaxation of the heart, but these changes are generally caused by the weakening or stiffening of the heart muscle. 

• Many diseases that affect the heart cause heart failure.

• It is often asymptomatic at first and gradually develops shortness of breath and fatigue over the course of days or months.

• Fluid may accumulate in the lungs, abdomen, or legs.

• Doctors usually suspect heart failure based on their symptoms, but usually do tests such as echocardiography (echocardiography) to assess cardiac function.

• Treatment focuses on treating the causative disorder of heart failure, improving lifestyle, and treating heart failure itself through procedures and drug use, including surgery.

Heart failure occurs at any age and even in young children (especially if they are born with an abnormality in the heart). However, older people are more likely to have heart failure-prone illnesses (such as coronary artery disease that damages the heart muscle ) ) and valvular heart disease, so they are much more common than in other age groups. Also, age-related changes in the heart tend to reduce heart function.

In the United States, heart failure occurs in about 6.5 million people and is newly occurring in about 960,000 people each year. It is found in about 26 million people worldwide. The number of patients with heart failure tends to increase due to longer life expectancy and the increasing number of people in some countries with risk factors for heart disease such as obesity , diabetes , smoking and high blood pressure .

Heart failure does not mean that the heart stops. The inability of the heart to maintain the movement (work) required to pump enough blood to all parts of the body. However, this definition has been somewhat simplified. Heart failure is a complex condition that cannot be simply defined because of its various causes, pathologies, classifications, and prognosis (prognosis).

The function of the heart is to pump blood like a pump. This pumping function pumps blood from one location to another. The heart has the following functions:

• The right part of the heart pumps the blood returned from the veins into the lungs

• The left part of the heart takes the blood that comes back from the lungs and sends it through the arteries to other parts of the body.

Blood exits the heart when the heart muscle contracts (systole) and flows into the heart when the heart muscle relaxes (diastole). Heart failure is caused by insufficient contraction and relaxation of the heart, which is generally caused by the weakening or stiffening of the As a result, a sufficient amount of blood will not be pumped. Congestion may also occur due to the accumulation of blood in the tissues. Therefore, such heart failure is called congestive heart failure.

Do you know?

Heart failure is sometimes called congestive heart failure because blood can collect in the tissue and cause congestion in that tissue.  Stagnation of blood flow into the left part of the heart causes congestion in the lungs, which makes breathing difficult. liver, etc.) and fluid accumulates. Heart failure usually has some effect on both the left and right sides of the heart, but it can also have a stronger effect on one side. In such cases, it may be called right heart failure or left heart failure. With heart failure, the heart cannot pump enough blood to supply the oxygen and nutrients needed by the whole body. As a result, the muscles of the legs and arms tend to get tired and the kidneys do not function properly. The kidneys are responsible for filtering blood and excreting water and waste products as urine, but when the heart's pumping function is inadequate, the kidneys function poorly and can remove excess water from the blood. You will not be able to. The result is a virtuous cycle of increased systemic blood flow, which increases the strain on the weakened heart. Therefore, heart failure is exacerbated.
