What are the classifications of heart failure

Heart failure refers to severe damage to the myocardium, which makes it impossible for the heart to pump enough blood to supply the whole body and various blood needs. In severe cases, even the heart itself may suffer from weakened heart function due to lack of blood. Therefore, heart failure is divided into different levels. The levels of heart failure can be divided into multiple stages. Sometimes it is not ruled out that it is caused by pathological factors. Depending on the different hearts, appropriate methods of treatment should be found. Generally, the cause of the disease should be found in the heart's blood supply. Because heart failure is likely to cause people to have breathing disorders and insufficient blood circulation in the body, it will cause obvious dizziness and headaches. These problems are quite harmful to the human body.

Grading:

1. Diagnosis of congestive heart disease: It is often not difficult to diagnose if there is a history of heart disease and symptoms and signs of left or right heart. X-ray examination of the heart and lungs is also helpful for diagnosis, and hemodynamic monitoring can be performed to confirm the diagnosis when necessary.

2. Determination of degree: Clinically, the patient's heart function is divided into four levels. If it is divided, it is divided into three degrees. Level 2 heart function is equivalent to level 1, and the rest are similar.

The heart function level 1 has cardiovascular function, but all labor is not restricted (no symptoms).

People with level 2 heart function can perform general daily work, but strenuous physical activities may cause symptoms of heart failure such as palpitations and shortness of breath.

People with level three heart function do not feel any discomfort when resting, but will show signs of heart failure when doing normal daily activities.

In heart function level 4, any activity will cause symptoms, and even when resting in bed, there will be symptoms of heart failure.

symptom

The symptoms will vary depending on which side of the heart is at fault. If both sides have problems, symptoms will appear on both sides.

The left side of the heart pumps blood from the lungs to the organs. Failure of the left side of the heart causes congestion in the pulmonary veins, resulting in insufficient blood supply to the tissues. The main respiratory symptoms are shortness of breath and, in severe cases, coma. Orthopnea can reduce shortness of breath while lying down, measuring the number of pillows needed to lie comfortably. Paroxysmal nocturnal dyspnea is severe cessation of breathing that occurs during the night, usually within a few hours of falling asleep. Inadequate circulation in the body causes dizziness, confusion, sweating, and cold extremities.

The right side of the heart pumps blood from the tissues to the lungs to exchange carbon dioxide for oxygen. Therefore, heart failure causes congestion of peripheral tissues. This can lead to peripheral fluid filling or generalized edema and nocturia. In severe cases, it can lead to abdominal effusion and hepatomegaly.

Decompensation can easily lead to heart failure. Heart failure may result from a variety of causes, including intermittent illnesses (such as pneumonia), but especially from myocardial infarction, anemia, hyperthyroidism, or arrhythmias, which place greater stress on the heart muscle and tend to make the condition worse rapidly. Large amounts of water or salt intake (including intravenous administration) and medications that cause fluid retention (such as nonsteroidal anti-inflammatory analgesics and thiazolidinediones) can also cause decompensation.

sign

Medical staff watch for specific signs to determine whether a person has heart failure. Signs of decompensation include apex beats and gallop rhythms. A heart murmur may indicate valve disease. Valvular disease may cause heart failure (such as aortic stenosis) or be a consequence of it (such as mitral regurgitation).

The main signs of left-sided heart failure are pulmonary edema, pleural effusion, and cyanosis.

Signs of right-sided heart failure include peripheral edema, peritoneal effusion, and hepatomegaly, with increased venous pressure, hepatojugular reflux, and a parasternal heave.
