Hypertension, diabetes and hyperlipidemia are the main causes of cardiovascular and cerebrovascular diseases. Insisting on proper exercise can prevent and control the three highs. If the three highs are effectively prevented and controlled, the incidence of natural cardiovascular and cerebrovascular diseases will be reduced. Therefore, exercise can control three highs, and after three highs control, cardiovascular and cerebrovascular diseases can be prevented and controlled, which is equivalent to exercise to prevent cardiovascular and cerebrovascular diseases.

Second, research on exercise and heart.

Exercise can improve heart function.

According to a study in the Journal of Circulation, any exercise will not cause myocardial stiffness. If the muscles become stiff, the ventricles will not be able to pump blood effectively, and the worst case is heart failure. Exercise can reverse the harm of sedentary heart aging and prevent the occurrence of heart disease and heart failure.

The results show that compared with inactive people, the risk of heart failure is reduced by 65,438+050% for those who exercise regularly for 65,438+050 minutes per week, and by 65,438+09% and 35% for those who reach twice and four times the recommended level.

2. The risk of dying of heart disease without exercise is twice as high.

The Journal of American College of Cardiology surveyed 149000 people and followed up for nearly 10 years. The conclusion is that people who sit for more than 8 hours a day are more likely to sit.

3. Exercise can prevent myocardial infarction.

Studies have shown that regular exercise can reduce the risk of 14% of myocardial infarction, while inactivity accounts for 12% of the risk of acute myocardial infarction.

For patients with coronary heart disease, as long as they can exercise without heart failure and angina pectoris, exercise can delay the progress of coronary heart disease, even eliminate coronary plaque, improve vascular endothelial function, improve coronary collateral circulation, improve left ventricular function and remodeling, and then reduce the risk of myocardial infarction and cardiovascular death.

For patients with myocardial infarction, under the guidance of doctors, proper exercise can improve cardiac function, and the biggest benefit is to start exercise rehabilitation from/kloc-0 to 3 months after acute phase.

Aerobic exercise, that is, moderate-intensity exercise, such as brisk walking, running, cycling, swimming, aerobic exercise, etc., can be used as a part of cardiac rehabilitation for patients with myocardial infarction or stent-graft bypass surgery, which can reduce cardiovascular death by 26% and hospitalization by 65,438+08%.

4. Can patients with heart failure exercise?

Our preliminary judgment on cardiac function and heart failure is based on activity tolerance, such as no symptoms at rest, and general physical activity causes symptoms such as excessive fatigue, palpitation, asthma, chest tightness, breath holding, etc., which belongs to cardiac function level 2; Less than normal physical activity can cause symptoms such as excessive fatigue, palpitation, asthma, chest tightness, breath holding, etc., which belongs to the third grade of cardiac function; At rest, there are symptoms such as fatigue, palpitation, asthma, chest tightness, suffocation, etc., which belong to the fourth grade of cardiac function.

That is, severe heart failure, has been unable to exercise. Does that mean that people with heart failure can't exercise

Studies have found that for patients with confirmed heart failure, insufficient physical activity will double the risk of all-cause death and cardiovascular death. At present, many heart failure guidelines suggest that patients with heart failure should have proper cardiopulmonary exercise training.
