The heart is one of the most important organs of the body and is the powerhouse of blood circulation. When something goes wrong with this engine, it can be dangerous. We need to protect the heart from time to time to avoid its problems. Exercise rehabilitation for heart patients is one of the effective means of treating heart disease and improving heart function. For people who are already suffering from heart disease, appropriate and moderate exercise under the guidance of a doctor can ease the development of heart disease and improve the function of the heart. Today we are going to talk about the problems that need to be paid attention to when exercising for heart patients. First, heart patients should avoid exercising in places far from the crowd. Some people with heart disease like to hike, climb mountains and other projects. These places are often far from the hospital, and rescue and treatment will be more difficult. Once a patient has a sudden acute heart attack, he or she cannot be rescued at the first time. So we recommend that patients try not to exercise alone, preferably in public places, or at home with family members around. Once you start to cold sweat, pale, slow heartbeat, breathing difficulties, you should immediately stop rest, symptoms do not ease, promptly call for help. Second, to avoid the “competitive” mentality. Some heart patients, who are in good health, do not believe that heart disease has had a huge impact on their bodies. When playing sports with their peers, they often have the mentality of competing to be the best, and they want to be first in everything. In fact, this group of people is not suitable for “competitive” competition, more than the body load of exercise, will increase the occurrence of cardiovascular events, and even increase the possibility of sudden death. Therefore, we recommend that in sports need to maintain a calm state of mind, enjoy the process of exercise rather than the results. Swimming is a good form of exercise for healthy people, but it may not be suitable for heart patients. Swimming is a whole body exercise and the load of the exercise is greater than conventional exercise. That is, it may be more physically demanding than other exercises per unit of time. At the same time some swimming pools water temperature is low, heart patients who do not have sufficient warm-up activities, suddenly into the cold water, will occur the whole body vascular spasm, blood pressure rose sharply, coronary artery blood supply is insufficient, cardiovascular accidents. We recommend that if you must choose to swim this project, before the exercise to carry out adequate warm-up exercises. At the same time, you need to choose a swimming pool with lifeguards and relatively more people, so that once there is an accident can be found and treated in time. During the exercise process try to choose breaststroke and other relatively labor-saving strokes, every 10 minutes to rest a while. Lower limb exercise is better than upper limb exercise. A study found that the blood pressure during upper limb activity is a little higher than during lower limb activity. For example, sports such as dumbbells, tensioners, single and double bars, tennis, badminton, etc., are more likely to cause an increase in blood pressure and increase the burden on the heart. At the same time, because of exercise, the blood supply to the upper limbs increases, which is more likely to shunt the blood from the heart and further increase the burden on the heart. Therefore, when heart patients exercise, it is best to start with lower limb exercise, walking is a better way, if the symptoms are heavy, you can walk slowly. If the symptoms are mild, you can walk quickly. After 3 to 6 months of persistent exercise, add upper limb exercise in due course, such as jogging, ballroom dancing, tai chi, radio gymnastics, etc. Exercise should have a target value. Exercise for cardiac patients is not better for longer periods of time. We recommend that every cardiac patient needs to go to the cardiac rehabilitation department of the hospital for a cardiopulmonary function assessment. Let your doctor inform you of the appropriate type of exercise and the appropriate duration of exercise. We generally assess the amount of exercise by the maximum heart rate of the exercise. So it is important to develop an exercise style and time that is appropriate with you. Try to avoid exercising in the morning. On the one hand, it is because the quality of control in the morning is poorer and the oxygen content in the air is lower. On the other hand, heart disease is at its “early peak” from 6 to 9 a.m. every day, especially angina and sudden death often occur around 9 a.m. The blood pressure in the morning is also the highest in the day, which can easily cause the detachment or rupture of atherosclerotic plaques, leading to acute cardiovascular and cerebrovascular events. Therefore, the exercise of heart patients, it is best to avoid this peak time, to arrange in the afternoon or evening is appropriate. Exercise should be regular and adhered to. And patients who adhere to regular exercise for a long time have a drop in blood pressure of up to 15 mm Hg, making the recurrence rate much lower. Exercise with regularity, first of all, should be quantitative, it is best to exercise 3-5 days a week, after exercise heart rate control at no more than 110 times 7 minutes (no chest tightness shortness of breath) is appropriate. Secondly, you may wish to follow the following three steps to exercise. First do preparatory activities for 5~10 minutes. Then start normal exercise, such as walking, jogging, etc., for 15~30 minutes (can also be extended appropriately according to the heart rate). Finally, do a 10-minute relaxation activity to allow the heart rate to slowly return to normal. We do not recommend a “three-minute fever” approach to exercise, where you exercise once on a whim and then stop exercising again. The prescription of exercise for heart patients is as important as the prescription of medication. Only when you know your heart and lung function, what kind of exercise you are suitable for, and how long your body can tolerate exercise, can you exercise safely. I hope that everyone with heart disease will be able to get the most benefit from exercise.
