Heart failure means that the heart is overloaded to the point that it can no longer complete its functions, also called heart failure.

The main function of the heart is to deliver enough blood to tissues throughout the body to supply the needs of normal life. If the heart is overburdened due to the heart itself or heart-related organs such as lungs, liver, kidneys, etc., the heart can compensate by accelerating the heart rate at first, but after continuous efforts to compensate, the myocardium thickens and the heart contracts. When the ability of the heart is no longer enough to send blood to the tissues of the body, it will cause a series of changes in the whole body, such as accelerated breathing, enlarged heart, enlarged liver, general edema, visceral blood stasis, etc. If not rescued in time, it will inevitably be life-threatening. .

How to be alert to heart failure?

Heart failure is the most serious manifestation of heart disease, medically called "heart failure" or "cardiac insufficiency", which can be seen in heart disease caused by various causes, including congenital heart disease and acquired heart disease disease, heart valve disease, myocarditis, pericarditis, etc. In addition, there are some diseases other than the heart that can also cause heart failure, such as acute nephritis, stubborn hypertension, chronic lung disease, etc.

Under normal circumstances, the heart’s “compensatory capacity” is very strong, which means it has great “potential”. Even if a small burden is added for a long time or a large burden is added for a short period of time, failure will not occur. Therefore, heart failure is more common in severe heart disease or heart disease with a long duration. What occurs in a short period of time is called "acute heart failure", and what develops gradually over a long period of time is called "chronic heart failure". Chronic heart failure is the most common type of heart failure. The main symptoms are: children are restless, have difficulty sleeping, cannot suck milk, refuse to eat, gasp when moving, and have cyanosis. Older children can complain about their condition, such as chest tightness, breathlessness, difficulty breathing, and inability to breathe. Lying flat, coughing, hemoptysis, edema of lower limbs and face, enlarged liver, oliguria, etc. If heart failure is discovered, timely rescue is required, otherwise the consequences will be very dangerous. At this time, parents should be particularly calm and calm, keep the sick child quiet, move it gently, and open doors and windows to make the indoor air fresh. And patiently comfort the sick child, never make him nervous or frightened, and call a doctor or go to the hospital immediately without delaying a moment.

Early signs of heart failure

Heart failure means that due to some reasons, myocardial contractility is significantly weakened, blood output is sharply reduced in a short period of time, causing circulatory disorders, and Produces insufficient blood supply to the arterial system and blood stasis in the venous system. Heart failure mostly occurs in the elderly, and its symptoms mainly include the following eight points:

① Difficulty breathing when working or going up stairs;

② Sudden difficulty breathing during sleep. Improvement occurs again when sitting up;

③ edema of lower limbs and decreased urine output;

④ cough, phlegm, palpitation, and shortness of breath despite not having a cold;

⑤ Insomnia, fatigue, and loss of appetite;

⑥ The condition worsens, with twitching of limbs, apnea, and cyanosis, but returns to normal immediately after the attack;

⑦ Blood pressure drops, heart rate accelerates, Pale complexion, clammy skin, irritability;

⑧Extreme difficulty in breathing, feeling of suffocation, coughing, and coughing up a large amount of pink foamy phlegm.

If 1-5 of the above symptoms can be matched, it is a typical manifestation of early heart failure and should be paid attention to; if 6 items can be matched, it is due to brain deficiency. Cardiac syncope caused by blood; if all are present, it is a symptom of acute pulmonary edema.

During the attack of heart failure, you should not move around. You can take a semi-recumbent or sitting position to reduce dyspnea. If you sweat a lot, keep warm and provide oxygen if possible. You can also use cloth straps to rotate the limbs and change them every 5-10 minutes. This can reduce the amount of blood returned to the heart and reduce the burden on the heart. The patient's mood should be stable and his spirit should be optimistic. After the condition is relieved, he can be sent to the hospital for diagnosis and treatment by a doctor.
