Sudden discomfort during exercise, is physical strength or sudden death?

Qiu Gao Qi is cool, it is a good time for healthy running. However, running also has to do it.

For the vast majority of healthy people, when running, walking, and riding bicycles, sweating, large breathing, etc. often occur, which is a normal physiological reaction after exercise. Only for a long time or severe exercise can it cause obvious discomfort such as asthma, chest tightness and even "stomach pain". The discomfort occurred in the exercise or light or heavy. In most cases, it will recover, but it is also related to heart disease. It needs to be vigilant and carefully distinguishes.

With the advent of the "national health running", why do some people who are not old are still taken away by small "running"? In fact, the relationship between exercise and sudden death is complicated, and the exercise itself must have a promotion of health. There are many reasons behind the tragedy. We cannot simply let the "health run" back.

Long -distance half -way syncope Coronary stenosis is the root of the scourge

Mr. Li is 66 years old and has a history of hypertension for more than 10 years. The highest blood pressure can reach 200/100mmHg. A year ago, Mr. Li fainted during the half marathon in the amateur group. He was quickly sent to the hospital for emergency treatment by volunteers and was discharged from hospital 3 days later. Although the accident did not leave any sequelae for Mr. Li this time, he still had worries and thought that "exercise had risks", and so far he dared not easily try high -intensity exercise.

In order to find out the root cause of the syncope, I issued the corresponding examination for Mr. Li: the results of the cardiopulmonary movement test were positive, showing that the multi -lead ST segment pressure and the AVR lead were lifted, and the blood pressure increased abnormally. I was shocked: This is at least multiple vascular lesions or left main lesions. Decisively suggested that he is hospitalized immediately to perform coronary angiography -shows that the three coronary veins are narrow! It turned out that Mr. Li's heart itself had problems. The half -horse competition caused the heart to load too much, which eventually led to this accident. We immediately dealt with the narrow coronary pulse, dredged the blood vessels, urged Mr. Li to actively lower the pressure, and then try to exercise after a period of time to promote the body as soon as possible.

Silation of running, this is actually a precursor to sudden heart death. Taken together, Mr. Li is sick first, and long -term exercise is more like a fuse, triggering the final explosion. Fortunately, the condition is not urgent, and the first aid is very timely and effective, which does not cause more serious accidents. If Mr. Li participates in long -distance running after that recovery, it is likely to cause the second and more severe syncope.

"Excessive exercise" is not the question of sudden death

Whether it is morning running or night running, or playing basketball, kicking football, etc., we are also considered "exercise" for exercise. When people have discomfort during exercise or after exercise, "non -traumatic deaths" (mostly caused by abnormal cardiopulmonary function) occurred, which is a sudden motion death.

The most common manifestation of sports sudden death is "sudden heart -based death", such as rapid ventricular tremor during exercise and post -occurring -this is a very fast and irregular beating, which makes the heart fail to contraction effectively and can not discharge enough enough. Blood eventually leads to hypoxia. At this time, if you cannot rescue in time, the condition will deteriorate rapidly. The most serious case is sudden death.

Many friends may say that sudden exercise death is caused by excessive exercise. In fact, it is like many people like "morning running" or "night running". They are because of the purpose of relaxation and activity, and the amount of exercise is not large. However, for those who already have hidden dangers of heart disease, this degree is not easy to grasp. Perhaps it looks very strong, and I didn't feel much tired when running, but it was enough to stimulate the lesion parts.

Calculate your "safety intensity" based on heart rate

It is not uncommon for accidents during exercise. Is the disadvantage of exercise? In fact, exercise itself has a promotion of health, and the relationship between exercise and sudden death is very complicated, and all the tragedies cannot be directly attributed to exercise. As mentioned earlier, excessive exercise is often just induced. Some people are usually normal. Only after exercise increases to a certain extent, various problems will appear.

This reminds everyone that exercise must control the intensity and do it under the "security activity intensity". Do not exceed the standard. In particular, people with chronic cardiovascular disease do the necessary evaluation before exercise, and the doctor conducts "dangerous layers", and forms a personalized amount of exercise and exercise intensity.

Heart rate is an important way to judge the intensity of exercise. The heart rate of adults is 60 to 100 times/min in a quiet state. The heart rate allowed by the general physical activity is "maximum heart rate (220 minus last age)". For the vast majority of people, the heart rate exceeds the maximum value and will not be able to breathe or dizzy. These symptoms are prompting you to "excessive exercise" and need to rest and not support it.

So, as long as the heart rate is lower than the "maximum heart rate", it must be safe? Not! First of all, we draw 50%-70%of the maximum heart rate as "low-to-medium-level sports intensity interval", and 70%-85%of the maximum heart rate is "intensity range of strenuous exercise". For safety reasons, healthy ordinary people should try not to exceed the "intensity range of the intense exercise", and those who have chronic diseases such as diabetes and hypertension are more suitable for "low medium exercise intensity interval".

Cardiovascular patients must do "risk layering" before exercise

When you are tired and tired, the best way to maintain is to rest. Some people are not just about tiredness, they have cardiovascular problems in themselves. It is recommended to do "risk layers" before exercise. According to the recommendations of relevant consensus, we divide the risk of sports -related cardiovascular risk into low -risk status and high -risk state: low -risk state athletes are not obviously different from those of the same age and the same sex. In popular terms, there is no complex ventricular arrhythmia, no angina pectoris symptoms, and stable blood flow dynamics during exercise. Only when high -intensity exercise can there be obvious shortness of breath and mild dizziness.

High -risk status combines a variety of risk factors such as senior, clear cardiovascular diseases, type 2 diabetes or kidney diseases, etc., or will participate in the movement of risky challenges, resulting in a significant increase in the absolute risk of exercise -related cardiovascular events. These people may feel dizziness, shortness of breath, or more severe symptoms such as angina pectoris, ventricular arrhythmia, and syncope after high -intensity exercise.

For people with low risk states, they can continue the current exercise intensity (friends who have no exercise habits in the past can start from low-medium intensity); high-risk people recommend further evaluation through "cardiopulmonary exercise experiments". For example, some people evaluate abnormalities such as the maximum oxygen volume, the increase in the center of movement, the slowdown in the movement of the exercise, the excessive blood pressure reaction, and the aggravation of the arrhythmia, which shows that they are not suitable for exercise or need to be dedicated to medical diagnosis and treatment and exercise guidance.
