Coronary heart disease is an irreversible chronic disease, must adhere to the rational use of medication on the basis of attention to self-adjustment in daily life, mainly including the following aspects: 1, avoid anger, anger Excessive excitement, tension, especially when the great joy and anger, the central nervous system’s stress response can promote small arterial blood vessel abnormally contraction leads to increased blood pressure, heartbeat accelerated, myocardial contraction enhancement, so the myocardium ischemia ischemia and hypoxia, which induced angina pectoris Or myocardial infarction. 2, avoid load exercise from their own objective reality, exercise should be measured. Overloaded exercise leads to acute ischemia or hypoxia of cardiovascular and cerebrovascular vessels, which may cause acute myocardial infarction or cerebrovascular accident. 3, avoid dehydration due to the elderly, especially patients with coronary heart disease blood viscosity have increased to a certain extent, can lead to ischemia or cerebrovascular blockage, serious cases can cause myocardial infarction or stroke. 4, avoid lack of oxygen coronary heart disease patients should often ventilate the living environment, when chest tightness or discomfort in the precordial area, in addition to taking emergency medicine, should be slow and deep inhalation immediately, the home is equipped with oxygen cylinders, oxygen can be inhaled for a few minutes, can relieve angina pectoris. 5, avoid cold and heat cold season, can cause peripheral vasoconstriction, accelerate heartbeat or coronary artery spasm. In addition, the cold can also increase the secretion of norepinephrine, blood pressure, therefore, coronary heart disease patients should pay attention to warmth when going out in the winter, brushing teeth in the morning, wash your face should be lukewarm water, laundry washing, do not soak your hands for a long time in cool water, in the hot summer, the amount of blood circulation in the human body increased dramatically, which can cause sympathetic nervous excitement, heartbeat acceleration, aggravate the heart of the extra burden. 6, avoid smoking and alcohol Smokers coronary heart disease incidence rate than non-smokers 3 times higher, too much alcohol can also make the myocardial oxygen consumption increase, aggravate coronary heart disease. 7, avoid oral hygiene If the oral cavity is unhygienic or suffer from periodontitis and other dental diseases, the oral cavity of gram-positive bacilli and streptococci may be blood circulation, so that small arteries spasm or thrombosis, resulting in myocardial infarction. 8, avoid oversaturation oversaturation can accelerate the burden on the heart, can also lead to vascular spasm, and even angina and acute myocardial infarction. Therefore, patients with coronary heart disease should usually have a small number of meals, especially dinner can only eat to seven or eight minutes full. In maintaining the above good habits at the same time, but also pay attention to adhere to the medication as prescribed by the doctor, and regularly go to the hospital for examination.
