Coronary heart disease is an irreversible chronic disease, once you put on this “hat”, we must be prepared for long-term “battle”. However, patients with coronary heart disease can also extend their lives with the disease. The key is to pay attention to self-conditioning in life on the basis of reasonable medication, including the following aspects: 1. avoid anger, anger The human central nervous system directs everything, when excessive excitement, tension, especially when the great joy and grief, the central nervous stress response, can make the small arteries vasoconstriction, resulting in increased blood pressure, heart rate, myocardial contraction enhanced, so that patients with coronary heart disease ischemia, hypoxia, thus inducing Angina pectoris or myocardial infarction. 2, avoid overload exercise from the objective reality of the elderly, exercise should be measured. In a quiet state, the heart muscle needs about 300 ml of blood supply per minute; large physical activity, the maximum amount of blood required by the heart muscle per minute up to about 2000 ml. It can be seen that the amount of overload exercise is very likely to lead to acute ischemia and hypoxia of the heart and brain vessels, which may cause acute myocardial infarction or cerebral infarction. 3, avoid dehydration Some elderly people usually do not develop the habit of drinking water regularly, until thirsty want to drink water, has caused varying degrees of “dehydration”, so the elderly usually have to develop the habit of drinking water regularly. Because the elderly, especially coronary heart disease patients have increased blood viscosity, to a certain extent, can appear blood clotting tendency, resulting in ischemia or blockage of the heart and brain vessels, in serious cases can cause myocardial infarction or stroke. 4, avoid lack of oxygen Generally speaking, in a day, in addition to outdoor activities or aerobic oxygen intake in line with physiological needs, other times the amount of oxygen intake is often insufficient, coronary heart disease patients are prone to chest tightness and other symptoms. If the long-term oxygen supply is insufficient, it will aggravate the degree of atherosclerosis. Therefore, patients with coronary heart disease should frequently ventilate their living environment and take a few deep breaths slowly when there is chest tightness or discomfort in the cardiothoracic area. When angina occurs, in addition to taking first aid drugs, should immediately inhale deeply, home with oxygen cylinders then inhale oxygen for a few minutes, can relieve angina and reduce the death of myocardial cells. 5, avoid the cold and heat cold season, coronary heart disease patients should not neglect the hands, head, face warmth. Because the cold in these parts can cause peripheral vasoconstriction, accelerating the heartbeat or coronary artery spasm. In addition, the cold can also increase the secretion of norepinephrine and increase blood pressure. Therefore, when coronary heart disease patients go out in winter, it is appropriate to wear masks, gloves and hats; brush teeth and wash face in the morning with warm water; laundry, washing dishes, do not soak hands in cold water for a long time. In the hot summer. The amount of human blood circulation increased substantially, which can make the sympathetic nerve excitement, heartbeat accelerated, and increase the additional burden on the heart. 6, avoid smoking and alcohol Smokers have a 3 times higher incidence of coronary heart disease than non-smokers. Regular consumption of strong alcohol can lead to heart disease and hyperlipidemia due to alcohol poisoning. Excess ethanol can also increase the oxygen consumption of the heart, aggravating coronary heart disease. 7, avoid oral hygiene If the oral cavity is not hygienic or suffering from periodontitis and other dental diseases, oral gram-positive bacilli and streptococci may enter the blood circulation, so that small arteries spasm or thrombosis, leading to myocardial infarction. 8, avoid overfull As overfull stomach can directly compress the heart, increasing the burden on the heart, can also lead to cardiovascular spasm, and even angina pectoris and acute myocardial infarction. Therefore, patients with coronary heart disease should usually eat less and more meals, especially dinner can only eat to seven or eight minutes full. In addition to maintaining the above-mentioned good lifestyle habits, attention should also be paid to medication. To regularly go to the hospital for examination, it is best to fix a hospital examination, monitoring the condition and symptomatic treatment; to adhere to the system of medication in accordance with medical advice.
