Heart failure (HF) is a disease caused by abnormal heart pumping function, which results in the heart being unable to meet the basic metabolic needs of the whole body. Common causes include myocardial infarction, cardiomyopathy, myocarditis, etc. High-risk groups include the elderly over 70 years old, with an incidence rate of more than 10% and a 5-year mortality rate of up to 50%. Heart failure can be divided into left heart failure, right heart failure and total heart failure according to the location of the lesion.

The main symptoms of heart failure include dyspnea, limited mobility and fluid retention. When the condition worsens, symptoms such as pulmonary congestion, shortness of breath, chest tightness, edema of both lower limbs, fatigue and dizziness may occur.

Treatments for heart failure include medication, cardiac resynchronization therapy (CRT), and implantable cardioverter defibrillator (ICD). Maintaining normal lifestyle and diet is also a very important part of the treatment process.

In addition, according to current research, the prevalence of heart failure is closely related to increasing age, and its 5-year mortality rate is as high as 50%.

The human heart is like a large water pump, which sends oxygenated blood to various oxygen-consuming organs throughout the body through arteries, and then returns the deoxygenated blood used by various organs to the heart through veins, and then is pumped to the lungs for oxygen replenishment.

This job is like the conveyor in the brewery in summer, which continuously transports the empty beer bottles to the beer canning workshop for canning, and then sends the canned beer bottles out of the brewery so that everyone can drink fresh beer again.

We can understand that the right heart is a conveyor that transports empty bottles to the loading and delivery workshop, while the left heart is a conveyor that transports full beer bottles to outside the factory.

Left heart failure is like a malfunctioning conveyor that carries full beer bottles out of the factory. The full beer bottles fill up the beer canning room, which is our lungs. Therefore, the manifestations of left heart failure are mostly related symptoms of pulmonary congestion.

Simple right heart failure is equivalent to the malfunction of the conveyor that transports empty bottles to the canning workshop. Many empty bottles cannot enter the canning workshop to be canned beer, resulting in the piles of empty beer bottles in various small shops outside that cannot be canned. In our body, it manifests as congestion in the systemic circulation (limbs, liver, kidneys, brain, etc.).

Of course, both left heart failure and right heart failure will gradually lead to damage to the other half of the heart function. If not controlled in time, it may lead to more serious total heart failure and endanger life.

Infection: Respiratory tract infection is the most common, and infection can aggravate pulmonary circulation congestion.

Arrhythmia: Atrial fibrillation is common, various types of rapid arrhythmias, severe bradycardias, etc.

Increased blood volume throughout the body: excessive and rapid infusion, high-salt diet, etc.

Excessive physical exertion or emotional excitement: late pregnancy, childbirth, rage, etc.

Improper treatment: Improper discontinuation of diuretics, antihypertensive drugs, etc.

Others: Exacerbation of existing heart disease or occurrence of other complications, such as myocardial infarction in patients with coronary heart disease.

Symptoms Heart failure is the terminal stage of heart disease. Understanding the triggering factors can reduce the acute onset of heart failure.

Total heart failure occurs in the late stage of heart disease. The condition is critical and may have clinical manifestations of both left and right heart failure. The main manifestations are related symptoms of insufficient blood perfusion to various tissues and organs, such as cold limbs, dizziness, oliguria, etc.

For patients who develop total heart failure due to left heart failure, symptoms such as dyspnea may be alleviated, but this does not mean that the condition has improved, but rather is a sign of worsening. Patients and their families should pay great attention to this.
