1, smoking: At present, a large-scale worldwide study shows that smoking is dangerous to human health, coronary heart disease patients are more harm than good, have this vice to resolutely quit. The nicotine contained in cigarettes can stimulate blood vessels to spasm, and at the same time can make the blood pressure rise, the heart rate increases, inducing angina. It was reported that a 41-year-old man, after smoking 20 cigarettes continuously, died of acute myocardial infarction. Foreign studies have also found that smoking 1 cigarette can reduce life expectancy by 12 minutes. Smoking is not only a public hazard, but also a private hazard, should be prohibited. 2, drink: a lot of alcohol can stimulate the decomposition of adipose tissue, the formation of a large number of fatty acids, so that the liver synthesis of pre-beta-lipoprotein amount sharply increased. At the same time pre-beta-lipoprotein and celiac particles in the blood to slow down the rate of decomposition and aggravate lipoproteinemia. Previous studies have found that alcohol consumption can induce angina pectoris and myocardial infarction. However, studies in the late 1980s concluded that small amounts of alcohol, especially at low levels, are cardioprotective. Therefore, the American Heart Association recommends that patients with coronary heart disease, even with myocardial infarction, can also drink low alcohol, drinking no more than 50 grams a day is appropriate. 3, drink coffee: coffee contains caffeine, can stimulate blood lipids and blood sugar increase. 1 cup of coffee contains about 100 mg to 150 mg of caffeine. A study found that long-term habit of drinking coffee, such as drinking more than 2 cups a day, its blood cholesterol levels and the incidence of coronary heart disease, than those who do not drink coffee or drink 1 cup a day or less significantly higher. In addition, drinking coffee can cause weight gain. Even if the amount of coffee consumed is small, it can cause an imbalance in the percentage of blood cholesterol. Therefore, it is recommended that people with hypercholesterolemia should stop drinking coffee immediately. Even healthy people with normal blood cholesterol levels should keep their coffee intake to a minimum if possible. We need to remind everyone that no matter how good coffee tastes, it is not as good as drinking plain water for the body. 4, drink tea: tea contains theophylline, vitamin C and tannic acid is beneficial to the body. China’s traditional production of tea, containing caffeine
Very little, helps digestion, and has a diuretic effect. Therefore, as long as it does not affect sleep, you can generally drink tea. But should also try to avoid drinking strong tea. Patients with myocardial infarction why not full meals and baths after a full meal? We have heard and seen more than once that some patients with myocardial infarction, because they could not resist the “kind” persuasion of family or friends and relatives and the lure of delicious food, a few more bites again induced myocardial infarction or even death. Other patients go to the bath after a full meal, the result of the bath soon collapsed in the bathroom, although the active resuscitation also did not help. Why is this? Under normal circumstances, the gastrointestinal tract is extremely vascular, and after eating, the cardiac output increases due to the need for digestion and absorption, and the abdominal organs are in a congested state. The necrotic myocardium of acute myocardial infarction patients has no contractility, and the heart function is very bad. On this basis, if the meal is full, on the one hand, the increase in cardiac output can increase the load on the heart; on the other hand, overfeeding makes the stomach expand and the diaphragm move up, which further affects the heart function; at the same time, it can also cause the gastric coronary reflex, so that the coronary arteries contract, the blood supply is reduced, and the myocardium is further ischemic and hypoxic.
In addition, the vagus nerve is excited after a full meal and the sinus node rhythm is reduced, which can cause cardiac arrest. For these reasons, the danger of bathing after a full meal is even greater. Because the whole body small blood vessels dilate after bathing, making the heart and brain more ischemic and hypoxic, so it is very easy to contribute to sudden death. What should coronary heart disease patients pay attention to during exercise? Exercise is certainly good for patients with coronary heart disease, but improper exercise, the harm brought to patients with coronary heart disease is not uncommon. Therefore, coronary heart disease patients in sports, must pay attention to the following issues: 1, before and after the exercise to avoid emotional excitement. Mental tension, emotional excitement can make the blood catecholamines increase, lowering the threshold of ventricular fibrillation. In addition to the risk of inducing ventricular fibrillation, therefore, for patients within three days of angina attack, within six months after myocardial infarction, should not do more strenuous exercise. 2, before exercise should not be full meal. Because the blood supply in the body needs to be redistributed after eating, the amount of blood flowing to the gastrointestinal help digestion increased, while the relative reduction in blood supply to the heart, easy to cause the relative lack of blood supply to the coronary arteries, thus occurring angina. 3, exercise should be gradual, persistent, usually do not exercise, do not suddenly engage in strenuous exercise. 4, exercise should avoid wearing too thick, affecting heat dissipation, increasing the heart rate. Increased heart rate will increase the oxygen consumption of the heart muscle. 5, avoid taking a hot bath immediately after exercise. Because the whole body immersed in hot water, is bound to cause extensive vasodilation, so that the heart blood supply is relatively reduced. 6, after exercise to avoid smoking. Some people often smoke as a rest after exercise, which is very harmful. Because the heart has a post-exercise vulnerable period, smoking is easy to make the blood free fatty acids rise and release of catecholamines, coupled with the role of nicotine easy to induce heart accidents.
