folks:
should rest after a heart attack, and
exercise is considered a taboo.
For patients with heart disease, relatives and friends around seem to take special care:
Do you have heart disease? Then you can relax!
Eat lightly, rest more and exercise less, take care of your body!
It seems to them that life is not about exercise, but about resting.
Is it true that you can only be a "greenhouse flower" if you have a heart attack?
For heart disease patients, should it be better to rest or exercise?
Let’s talk about it today.
Cardiac rehabilitation depends on resting?
Many patients have this misunderstanding: you must take a rest when you are sick.
As everyone knows, just blindly emphasize bed rest and strictly restrict physical activity. Sometimes not only does not recover from illness, but also because of exercise volume decreases.Bring more harm.
Because the cardiopulmonary function of the human body needs to be strengthened through active exercise, if you stay in bed for a long time or do not move:
In one aspect, will lead to the decline of various organs, deterioration of body functions, and serious impact on life The quality is not conducive to the recovery of heart function;
On the other hand, , patients with heart disease are relatively more accompanied by different degrees of arteriosclerosis and even vascular plaque. Long-term immobility will only aggravate the situation, even Poor blood circulation may also lead to venous thrombosis, leading to critical diseases such as pulmonary embolism.
At this time, scientific exercise training is needed to enable patients with heart disease to safely and effectively restore heart function.
Heart rehabilitation lies in scientific movement!
Studies have pointed out that after a heart attack patient, if can maintain a good physical condition, it can reduce the probability of a second attack by 60%!
Because scientific exercise is good for the physical and mental health of patients, especially for patients with high physical disabilities, exercise has many benefits.
1. Exercise is the key to weight control
Whether it is to lose weight or regulate blood lipids,Almost all are inseparable from exercise, and once the weight is controlled, it can not only prevent the three highs, but also improve myocardial function.
2. Exercise can delay arteriosclerosis
Long-term exercise can improve vascular endothelial function, promote vascular plaque repair and stabilize vascular endothelial function. Effectively, it can also promote the formation of coronary artery vascular collateral circulation, realize self-vascular bypass, and delay the development of atherosclerosis is very helpful.
3. Exercise can regulate blood pressure and heart rate
Scientific exercise can stabilize mood, improve sleep and increase heart rate.
4. Exercise can also improve myocardial ischemia .
For the heart, proper exercise can improve myocardial mitochondrial function, enhance myocardial function, increase myocardial pumping function, and increase the body's oxygen utilization and blood circulation efficiency.
5. Exercise reduces the risk of sudden death
Exercise can improve myocardial tolerance to hypoxia.In turn, it reduces myocardial damage and the risk of possible fatal arrhythmia, which are related factors that may increase the risk of sudden death. So exercise can reduce the risk of sudden cardiac death.
Therefore, moderate scientific exercise can help control and recover from heart disease.
But how can a more "scientific" movement be made?
Of course, heart disease patients are different from ordinary healthy people after all, and they cannot exercise too much.
And for heart disease patients, the type and severity of the heart disease are different, and the appropriate exercise intensity is also different.
Therefore, it is necessary to go through the hospital's physical examination and physical assessment (from the patient's physical fitness, heart load, heart rate, lung function and other aspects to evaluate) , in order to develop a targeted exercise method, do There are "prescriptions" for sports, so that patients can participate in sports exercises more safely and effectively.
This "prescription" refers to the exercise prescription prescribed by the doctor.
The exercise prescription mainly includes two aspects, one is exercise intensity and the other is exercise method.
Among them, moderate exercise is very important. High exercise intensity can easily lead to injury and even overwhelm the heart.
How do we judge whether the exercise intensity is appropriate?
can be judged mainly by the following three indicators:
1. Target heart rate: is the heart rate to be achieved during exercise. During exercise, the heart rate will increase to meet the oxygen demand of the muscles. The more intense the exercise, the faster the heart rate. You can adjust the exercise intensity according to the target heart rate established by the exercise prescription. If the heart rate is lower than the target heart rate, you can slowly increase the speed and intensity to ensure the effectiveness and safety of the exercise.
2. Talk: Exercise makes your breathing deeper and faster than usual, but you should not feel short of breath. When you are exercising, you can still maintain a normal conversation speed, indicating that the exercise intensity is moderate at this time.
3. Self-perceived fatigue: uses the self-perceived effort rating (RPE) to be divided into 6-20 grades from low to high, and self-test the degree of fatigue, generally choose 13 level, that is, feel a little while exercising Try hard, but you shouldn’t feel too hard.
Of course, the choice of exercise mode is also very important, aerobic exercise is the first choice!
Aerobic exercise refers to durable exercise for the purpose of enhancing the inhalation, delivery and use of oxygen by the human body.People need to increase the supply of oxygen during exercise, and the body itself can meet this demand by appropriately increasing the heartbeat and respiration during aerobic metabolic exercise, and achieve a balance between oxygen supply and demand.
Taking running as an example, middle and long distance running (800, 1500 meters) belongs to semi-aerobic metabolism, and the longer distance is mainly anaerobic metabolism.
Actually, anaerobic exercise is not advocated in cardiac rehabilitation, because anaerobic exercise refers to the high-speed and vigorous exercise of the muscles in the state of "hypoxia", which may cause such high-intensity exercise for the elderly The risk of angina and myocardial infarction.
Strong3strong fast walking is the safest and wise choice for the elderly.
Of course, jogging is also a good sport, but it is more likely to cause joint and ligament damage than brisk walking. Brisk walking can enable people to obtain ideal endurance, and will not stimulate the production of too many harmful free radicals due to excessive exercise, and there is no danger of damaging bones and muscles.
In addition, Tai Chi, mountain climbing, Tai Chi, cycling and swimming are all good aerobic exercise options
0p at the same time Also pay attention to exercise frequency and time: only effective and regular exercise, the heart will benefit. After the condition is stable, it is recommended to exercise more than 15 minutes each time,The best is 30-60min or about 3km, 5 times/week.
Which heart disease patients are not suitable for exercise rehabilitation?
Most patients with stable heart disease and before and after heart surgery can implement their own sports rehabilitation program under the guidance of a doctor, but if the patient has the following conditions, it is not suitable for sports exercise:
unstable angina pectoris; unstable blood pressure with significant hypotension or hypertension; severe arrhythmia; uncontrolled heart failure or acute heart failure; recent embolic disease; stent surgery, coronary artery Patients with unstable condition after bypass surgery and pacemaker surgery; aortic aneurysm, etc.
It is necessary to remind heart patients that exercise rehabilitation has many benefits, but lack of doctor's guidance will increase the risk of cardiovascular events.
If a heart disease patient is not checked, chooses an inappropriate exercise method, exercises beyond the safe range, wrong exercise time, insufficient preparation activities, etc., it is very likely to aggravate the underlying disease and induce severe heart rhythm Disorders, and even sudden death.
If conditions permit, it is recommended to perform scientific rehabilitation exercises under the supervision of a professional cardiac rehabilitation physician.
In short, most heart disease patients can improve their symptoms and delay the development of the disease by insisting on scientific and moderate exercise. But the premise is that it must be carried out under the guidance of a doctor and health monitoring.Once uncomfortable symptoms occur, immediately stop exercising and seek professional help.
So, heart patients, don't let the heart disease carry your lazy late-stage cancer scapegoat, go out and enjoy the happiness and health brought by exercise.
may be able to control the heart disease to death, so that it has no chance of trouble.
For the majority of healthy people, exercise has more benefits. Take advantage of your good health now, hurry up and move!
