The heart is one of the most diligent organs in the body, working diligently every minute, but people often ignore its importance and only think of it when they are uncomfortable. Autumn and winter are the high incidence of heart disease, because of the frequent activities of cold air and the large temperature difference between morning and evening, it is easy to induce heart disease. A sudden attack is likely to pose a serious threat, and it is crucial to do a good job of heart disease prevention in the fall and winter. Understanding the heart The heart is the single most important organ in the human and vertebrate body, with the primary function of providing pressure and running blood to all parts of the body. The human heart is located to the left of the middle of the chest cavity and is about the size of a fist and weighs about 350 grams. The female heart is usually smaller and lighter than the male heart. The human heart is shaped like a peach and is located above the diaphragm, between the two lungs and to the left. Role of the heart The role of the heart is to drive blood flow, provide adequate blood flow to organs and tissues to supply oxygen and various nutrients, and carry away the end products of metabolism (such as carbon dioxide, inorganic salts, urea and uric acid) so that cells maintain normal metabolism and function. Common heart-like diseases Heart disease is a general term for heart diseases, including rheumatic heart disease, congenital heart disease, hypertensive heart disease, coronary heart disease, myocarditis, and various other heart diseases. Heart disease is a relatively common type of circulatory system disease. The circulatory system consists of the heart, blood vessels and neurohumoral tissues that regulate blood circulation. Diseases of the circulatory system, also known as cardiovascular diseases, include diseases of all the above-mentioned tissues and organs, and are common among internal diseases, of which heart disease is the most common and can significantly affect the patient’s labor force. The physical characteristics of heart disease 1, breathing will not be smooth, the chest will be stuffy will also stabbing pain, stabbing pain is short-lived, a few seconds after the onset of a few seconds, at most a minute. Severe will be from the front of the chest pain to the back of the anointed scapula place will come once every ten days and a half months, three or five months an attack, the shorter the time the more serious. 2, the heart is bad will be involved in the left arm soreness, numbness, pain, because the nerve of the heart and the left arm nerve is the same, so the left heart problems will be involved in the left arm. 3, the heart will also be involved in the neck stiffness, inflexible rotation, get up in the morning neck often twisted; because of heart problems, the carotid artery will be narrow, blood supply is not smooth, the next tendon blood loss natural stiffness. Is the accelerated heartbeat a heart attack? Nowadays, many young people think that heart disease is only a matter for the elderly, but they do not know that if the heart is not protected, everyone has a hidden heart problem. Many young people without underlying illnesses may experience a rapid heartbeat after mood swings, mental stress, shock, exercise, excessive smoking, or drinking. Although an accelerated heartbeat is not a heart disease, a fast heart rate is certainly not good. A tachycardia, which tends to increase the risk of developing cardiovascular diseases. Are premature beats serious Premature beats are heart beats caused by premature impulses from ectopic pacing points and are the most common arrhythmia. Premature beats can occur in healthy people and people with heart disease, and can be triggered by stress, alcohol, coffee, and poor sleep. Premature beats can be benign or malignant. Except for heart disease patients, premature beats in the general population are mostly benign and may not be treated. However, if it is caused by coronary heart disease or high blood pressure, it should be taken seriously. The optimal frequency of heartbeat From the physiological point of view, one heartbeat is the heart’s completion of a pumping task. In general, it is better for a healthy person to have a slower heartbeat. Because a slow heartbeat tends to be more powerful – other people need to beat 80 times a minute to complete the work if only 60 beats can be completed, indicating that such a heart works more efficiently. The faster the heart beats, the more work it does, the more energy it consumes, and the more easily the heart fatigues. Generally speaking, young people who love sports or professional athletes have a relatively slow heartbeat. Normal human heart rate, 60-80 times / min when awake, sleep state in 40-60 times / min is good. The impact of obesity on heart health It is estimated that the work done by a person’s heart pumping blood throughout his life is equivalent to lifting 30,000 kilograms upwards to the top of the Himalayas. The heavier a person is, the greater the burden on the heart. In other words, the heart needs to work harder to get the blood needed for all parts of the body, including muscles and tissues, in place. Overworking the heart over time can lead to hypertrophy of the heart muscle, especially the left ventricle, which can lead to high blood pressure and other heart diseases. In addition, the excess visceral fat that comes with being overweight can also squeeze the heart and affect its normal work. Exercise and heart health Aerobic exercise is the best form of exercise for cardiovascular health, with brisk walking being one of the safest aerobic metabolic exercise programs. In addition, jogging is also a good exercise program, but compared with fast walking may be more likely to cause joint and ligament damage. But exercise is also a double-edged sword, after a busy day if engaged in too strenuous exercise, may cause increased blood pressure, heart rate, myocardial ischemia and hypoxia, resulting in cerebral hemorrhage, angina, myocardial infarction and even sudden death. Therefore, for long-term brain workers, walking is the safest and most promotable way to exercise with love. How to protect heart health Simply put, there are two kinds: 1. change lifestyle: quit smoking and drinking, proper exercise, regular diet, meat and vegetables, and less greasy food. From the perspective of heart disease prevention and treatment, nutritional factors are very important. In principle, we should achieve the “three low” that is: low calories, low fat, low cholesterol. 2, high-risk groups with drugs: people with heart disease must take drugs regularly according to medical advice. For the sake of our own health, and for the sake of those who love us, we must protect our heart.
