Suggested precautions may include: weight control Studies have shown that a 10% increase in body weight increases cholesterol by an average of 18.5 and increases the risk of coronary heart disease by 38%; a 20% increase in body weight increases the risk of coronary heart disease by 86% and increases the prevalence of coronary heart disease by a factor of 1 in hypertensive patients with diabetes than in hypertensive patients without diabetes. Quit smoking The nicotine in tobacco increases heart rate, increases blood pressure (which can be lowered by excessive smoking), increases oxygen consumption by the heart, vasospasm, abnormal blood flow, and increases platelet adhesion. These adverse effects make the incidence of coronary heart disease three times higher in men aged 30-49 who smoke than in nonsmokers, and smoking is also an important cause of angina attacks and sudden death. Quit drinking An experiment by American scientists confirmed that ethanol has a toxic effect on the heart. Excessive ethanol intake can reduce the contractility of the heart muscle. For people with heart disease, alcohol abuse not only increases the burden on the heart, but can even lead to arrhythmias and affect fat metabolism, promoting the formation of atherosclerosis. Improve the living environment Places with serious pollution and high noise intensity may induce heart disease. Therefore, improve the living environment, expand the green area, reduce the noise and prevent all kinds of pollution. Avoid crowding Avoid going to places where people are crowded. Whether it is viral myocarditis, dilated cardiomyopathy, coronary heart disease or wind heart disease, they are all related to viral infection, and even heart failure is often caused by acute exacerbation due to upper respiratory tract infection. Therefore, care should be taken to avoid going to crowded places, especially during the flu season, to avoid getting infected. Reasonable diet There should be a reasonable dietary arrangement. Hyperlipidemia, unbalanced diet, diabetes and obesity are all related to dietary nutrition, so nutritional factors are very important from the perspective of heart disease prevention and treatment. In principle, we should achieve “three low”, namely: low calorie, low fat and low cholesterol. The right amount of exercise Actively participate in the right amount of sports. Maintaining regular and appropriate exercise is good for enhancing heart function and promoting normal body metabolism, especially for promoting fat metabolism and preventing the occurrence of atherosclerosis. For heart disease patients, according to the function of the heart and physical strength, engaging in an appropriate amount of physical activity can help improve blood circulation, enhance resistance, improve the function of all organs of the body, and prevent thrombosis. However, it is necessary to avoid too strenuous activities, and the amount of activities should be gradually increased in order not to cause symptoms. Regular life Develop healthy living habits. Have a regular life, be happy, avoid emotional excitement and overwork.
