Get up early in the morning and exercise, this is the living habit of many people. Some elderly people have short sleep time and are willing to get up early to exercise. However, early morning is not a good time to exercise, especially for the elderly and patients with cardiovascular disease, because early morning and morning periods are the high incidence of cardiovascular disease .
Just a few days ago, a patient told about her family’s “sudden cardiac death”.
The father-in-law of the patient is in his 70s, has a history of hypertension and , and usually takes antihypertensive drugs. The elderly like morning exercises and get up early every day to go out for exercise. I am getting older and woke up earlier in the morning and get up at around 5 o'clock to exercise.
A week ago, in late autumn in Beijing, the elderly felt their throats burning and stuffy when they went out for exercise in the morning. They still didn't care after going home to rest, and they didn't care. They didn't go to the hospital. After lunch, they went back to the bedroom to rest. The TV was turned on, and it was quite loud.
to 3 pm, the old man has not yet left the house. My family felt abnormal and went into the house to see that the old man had already fallen on the bed, salivating, lost consciousness, and breathing. Call for first aid immediately. The doctor came and the examination confirmed that the old man had passed away long ago. He judged that it was "sudden cardiac death."
Elderly men and patients with hypertension are the high-risk groups for cardiovascular disease. I don’t know if the elderly pay attention to lowering blood pressure while lowering blood cholesterol; I don’t know if the elderly have ever experienced such throat discomfort and stuffy during this activity in their daily lives, because this highly suggests an angina pectoris attack. This kind of discomfort, burning and stuffy feeling related to physical activity, from the throat to the under xiphoid process, which lasts for a few minutes or more, is a typical angina pectoris symptoms . If it appears, you need to seek medical treatment in time.
Early morning to morning is the high incidence of cardiovascular acute diseases.
has been confirmed by studies in recent years that myocardial infarction, sudden cardiac death and stroke have the highest incidence rates between 6:00 and 12:00 . A Berlin emergency medical team analyzed more than 20,000 cases of sudden death in and found that sudden death in winter is the highest in all seasons of the year; sudden death from 6:00 to 12:00 is the highest, especially for people >65 years old. Tianjin Emergency Center analyzed more than 1,000 sudden deaths, and the same was found. Specifically for the study of sudden death from coronary heart disease, the incidence rate is also the highest at 6 o'clock to 12 o'clock. Therefore, this period of is called " devil period " of cardiovascular disease.
Why is the incidence of cardiovascular acute and sudden cardiac death high in the morning and morning?
- from the principles of medicine, mainly in the early morning sympathetic nervous system excitement .
Sympathetic nerve excitation will increase many substances that affect the cardiovascular system, such as catecholamines, corticosteroids, etc., which will accelerate the heart rate and increase blood pressure, increase the workload of the heart, and the sick heart will be ischemia and hypoxia; sympathetic nerve excitation will affect the activity of the cardiocardiogram and can induce arrhythmia ; catecholamines will promote coronary artery contraction; and in the early morning, platelet activity is high, there are many coagulation substances, and the blood is prone to condense into thrombosis.
- The weather is cold, which can stimulate blood vessels to strongly contract .
Day and night temperature difference is large, and the temperature is low in the early morning, especially in cold seasons such as late autumn and early spring and winter. The temperature difference between indoor and outdoor areas is large, and outdoor Cold stimulation will cause strong blood vessels to contract . The peripheral blood vessels contract, blood pressure increases, coronary artery contraction (spasm), myocardial ischemia , and the consequences may lead to rupture of plaques in the blood vessels. Even in the warmer weather in Guangzhou, sudden cardiac death is also at a high rate from December to February. On the day the old man died suddenly, the outdoor temperature was only 6 to 7℃ in the morning, and the stimulation of the cold may be the cause of the disease.
- The atmosphere is polluted severely in the morning, and many harmful substances in the air will increase the risk of cardiovascular death .
environmental air pollution , and the increase in PM2.5, coarse particles, ozone , nitrogen dioxide , carbon monoxide and other substances in the air increase. will increase the risk of death in cardiovascular disease, and is also related to the increased risk of death in coronary heart disease and hypertension . It is the third risk factor affecting my country's disability-adjusted lifespan (healthy lifespan lost due to premature death, disease and disability). The pollution situation is that the north is more important than the south and winter is more important than summer. In the cold season in the north, the air pressure is low in the early morning, and pollutants do not easily dissipate, which is a period of relatively severe pollution.
- cardiovascular patients are also a high incidence of diabetes . Exercising on an empty stomach in the morning can easily cause hypoglycemia and is also unfavorable to cardiovascular and cerebrovascular .
Therefore, early morning is not a good time to exercise, especially in the cold season, which is particularly unfavorable for patients with cardiovascular disease.
It’s time for someone to ask, when is it better to exercise?
Study the impact of walking exercise on inflammatory indicators in different time periods of coronary heart patients and found that walking exercise can improve inflammatory indicators, but evening exercise is obviously better than morning exercise. Some people also conducted research on patients with stent with coronary heart disease. They found that the heart rate indicators of patients have improved after rehabilitation exercise, and afternoon exercise is significantly improved compared with morning exercise. For people without coronary heart disease, research has found that afternoon or evening exercise is also more effective in preventing it.
Therefore, is a better time to exercise, and is more suitable for about 1 hour after dinner.
