The full name of heart failure is called heart failure, which is defined in the textbooks as a set of syndromes resulting from various heart structures or functional diseases that lead to CPR and/or loss of blood-shooting capacity. Owing to the loss of blood-emitting function in the heart room, the failure of the heart drain to meet the need for aerobic metabolism, insufficient infusion of organs, tissue blood, combined with pulmonary circulation and/or cyclic silt, clinical performance was mainly limited physical activity and oedema due to respiratory difficulties and incapacity. As cardiovascular diseases such as hypertension, diabetes and coronary heart disease are increasing, the number of patients eventually leading to heart failure increases every year, and since heart failure is in fact an end state for all heart diseases, with even comparable rates of survival and cancer, it will be difficult to cure if heart failure occurs, so it is important to reduce the harm of heart failure and, above all, to prevent heart failure and understand the causes of heart failure.
The heart is like a pump in a body that collects and discharges blood, which is the engine of a car, which drives the blood to operate in its veins, with a constant supply of organs of the whole body, transports oxygen and other nutrients, and collects the blood to regenerate. Heart failure occurs when, for a variety of reasons, the heart is not functioning and working, like a flex-deficit leather ball, when the blood produced does not meet the needs of organs and tissues, and when the blood of the outer circle does not flow back to the heart. Uncompletely measured heart failure affects more than 60 million people worldwide, as there is insufficient awareness of the disease, about a third of patients misperception of heart failure as a normal phenomenon of ageing, and the same statistics show that a quarter of patients visit treatment at least one week after the onset of heart failure, or do not visit at all, leading to delays in treatment.
Heart failure can be caused by heart disease of all kinds, and we see heart failure as the final stage of heart disease of all kinds, so there are many causes of heart failure. In general, we can divide it into two broad categories: damage to the original cardiac muscles and permanent overloading of the heart:
1. Initial myocardial damage, i.e. heart failure due to a heart problem per se (1) ischaemic myocardial damage: coronary heart attack, in particular myocardial infarction, severe damage to the muscles of the heart, a decline in the constrictive function of the heart, and a decrease in the ability to deliver blood into the blood vessels is one of the most common causes of heart failure. (2) Cardiacitis and myocardial disease: Cardiac failure can be caused by various types of myocardiitis and myocardial disease, with viral myocarditis and primary expansionary myocardial disease most common. (3) Myocardial obstructive diseases: Diabetes myocardial diseases are most common.
2. Heart loads, including pressure loads (i.e., pressure to be overcome during heart contraction) capacity loads (the most important capacity in the body is blood, which is the equivalent of the cargo transported on a car, and the greater the load on the heart engine) (1) Pressure loads: there is a common high blood pressure and a number of heart valve diseases, such as narrow aortic valves, pulmonary hypertension, narrow pulmonary artery valves, and a number of obstacles on the path of the heart to pump blood out of the body, which leads to increased heart-jection resistance. In order to overcome the increased resistance, the heart muscles are graft to ensure blood injection. Persistent overloads entail structural and functional changes in the myocardial muscles leading to a failure and a reduction in the heart drain. (2) Overloading: See: Incompletely closed heart valves, reverse blood flow, e.g., partially closed arcal valves, incompletely closed dipods, etc.; 2 left, right or aerodynamic congenital cardiovascular diseases, e.g., missing spacing, unclosed arterial catheters, etc. In addition, diseases associated with increased body capacity or circulatory blood, such as chronic anaemia, thyroid hyperactivity, etc., are bound to increase the capacity of the heart. The early increase in the capacity load, the expansion of the cystal cavity compensation, and the maintenance of the myocardial condensation function have been sustained, but there have been changes in myocardial structure and function beyond a certain limit.
For people with basic heart disease, the symptoms of heart failure are often induced by factors that increase heart load. Common causes of heart failure include cold infections, excessive salt or liquid intake, increased physical activity, emotional agitation, etc.
Thus, the prevention of heart failure begins with the prevention of the above-mentioned risk factors, the strict control of blood pressure, blood sugar and blood resin, the reduction of the risk of coronary heart disease, the periodic examination of the heart, the early detection of many heart diseases, and, if heart failure has occurred, the avoidance of the factors that induce heart decay, such as the prevention of cold infections, the restriction of salt and water intake, control of physical activity, and the avoidance of psychopsytic stimulation, in addition to the treatment that is regulated.
