(1) heat energy
It is advisable to maintain an ideal weight, in which age and physical activity are the most important. After middle age, with the increase of age, daily activities such as physical activity are relatively reduced, and the basal metabolic rate is also decreasing, so the daily heat energy required is also reduced accordingly. If you are overweight, you should reduce the supply of heat energy to lose weight. The simplest way to evaluate whether the weight is normal is to subtract 105 from the height cm as the upper weight limit. Standard weight (kg) = height (cm)-105 (or110); Over 30 years old > 15% overweight under 30 years old > standard weight 10% overweight, > standard weight 20% obese. Protein accounts for 13% ~ 15% of the total heat energy, and fat accounts for 1. When treating diet, the polyunsaturated fatty acids are 15 ~ 20g/d, and the P/S ratio should be >; 2.o foods with high animal fat content are prohibited.
(3) limiting cholesterol
As a preventive diet, the supply of dietary cholesterol should be limited to below 300mg/day, and as a therapeutic diet, it should be limited to below 200mg/day; Foods with high cholesterol are forbidden. See table 18-2 for fatty acid and cholesterol content and P/S ratio.
(4) Carbohydrate
It is advisable to choose polysaccharides and carbohydrates, which occupy heat energy. Question 2: How to deal with myocardial ischemia? Your age and symptoms don't look like myocardial ischemia, and it's no use taking Chinese medicine. It is impossible to diagnose myocardial ischemia only by ECG. Young people generally don't get myocardial ischemia or coronary heart disease. It is normal for your heart to beat faster when you are nervous or excited and at work, but the symptoms are obvious. You should check and rule out arrhythmia. For example, if you feel that your heart is beating fast and uncomfortable, you can do a 24-hour electrocardiogram (Holter) to evaluate the 24-hour heart rate and whether there is arrhythmia. In addition, do a heart color Doppler ultrasound to rule out structural problems of the heart. If everything is ok, don't worry. Adjust your lifestyle. I don't know how much you weigh. Control your weight, pay attention to rest, adjust your lifestyle, and don't care too much about normal study and life. It may be relieved after a while.
Question 3: How is myocardial ischemia caused? Hello, several causes of myocardial ischemia 1. Overworked heart and excessive myocardial blood consumption can cause relative myocardial ischemia. 2. Hypovolemia and systemic ischemia can cause corresponding myocardial ischemia. 3. The blood vessels supplying blood to the myocardium are not smooth, which will cause myocardial ischemia. 4. Excessive aggregation of red blood cells, blood viscosity and impurities can cause myocardial blood circulation ischemia. I hope I can help you and wish you health!
