Surveys show that one person dies of heart disease every three minutes in China. Among all heart diseases, especially coronary heart disease is the most common. The main cause of coronary artery disease is the narrowing of the arterial cavity caused by atherosclerosis, which can cause a series of symptoms such as heart ischemia, angina, panic and shortness of breath, fatigue and other symptoms. In severe cases, it can even be directly life-threatening. Stable coronary heart disease is a type of coronary heart disease in which the degree, frequency, nature and triggering factors of angina attacks do not change significantly within weeks. The common symptom is that the patient is behind the middle or upper part of the sternal body, which can spread to the precordial region, often with radiating pain that can radiate to the left shoulder, the inner left upper limb, the neck, the pharynx or the jaw, etc. The site of each angina attack is often similar. Generally, for such patients, clinical interventions are mostly carried out by means of intensive optimization of drug therapy. However, because stable coronary artery disease is stable and does not fluctuate significantly, patients are prone to laxity in treatment and often fail to take medications on time, neglect follow-up, and lead an unhealthy lifestyle (e.g., smoking, alcohol abuse, etc.), which leads to a poor prognosis of the disease. People with stable coronary artery disease should start their daily life to prevent the disease from occurring. First, manage your blood pressure. Among the above risk factors, hypertension bears the brunt. Abnormal blood pressure can cause damage to the brain, heart and kidneys, and this damage is a slow accumulation process. In addition to measuring blood pressure, it is important to eat a daily diet with less salt and more vegetables. Second, weight control. Abdominal obesity is precisely a very important reference indicator of cardiovascular disease. Therefore, we should do a healthy diet, control the mouth, and eat less food high in oil and fat. Third, quickly quit smoking and drink alcohol in moderation. Smoking is one of the most important risk factors for coronary heart disease, a study found that smokers compared with non-smokers, the incidence of coronary heart disease and mortality increased by 2 to 6 times, and proportional to the number of cigarettes smoked per day. Finally, move. The longer a person’s static life (time spent watching TV, reading, using the computer, etc.), the greater their body mass index, the higher their blood pressure, and the significantly higher their blood sugar and lipids. Therefore, from now on open your legs, brisk walking, jogging, swimming, playing tai chi can be, swimming this exercise for cardiorespiratory function is very good, need to adhere to.
