45-year-old Mr. Wang went out to run and exercise almost every day. Even in the cold winter, he still insisted on "check-in". I wanted to keep fit, but I didn't expect that I had a sudden chest tightness when I ran in the morning the day before, but I had no choice but to give up. Sudden myocardial infarction. Doctors remind that the temperature in winter is reduced, and the blood vessels are susceptible to contraction by cold stimuli. Therefore, it is important that you exercise early and late in the morning, especially those who are frail and old, to master scientific exercise methods.
Mr. Wang, 45, is a sportsman. The first thing to get up early every day is to exercise "check-in". As long as the weather allows, he will go out for a dozen kilometers, sweat and go to work. This habit persisted for more than 8 years, and he also got rid of his middle-aged greasy "belly belly" and successfully lost weight.
At 5 o'clock in the morning the day before yesterday, Mr. Wang put on his equipment and went out to Wuchang River Beach as usual to run. At that time, the mobile phone showed that the temperature was only 4 ° C. He didn't care too much, and after the warm-up, he started running according to the planned route. When completing 5 kilometers, Mr. Wang felt his legs and feet were soft, and Jiang Feng was blowing cold for a while, but he did not want to give up halfway, and insisted on running for another 1.5 kilometers. At this time, his chest began to feel sullen and uncomfortable. a feeling of.
In desperation, Mr. Wang had to go home to rest, but his sullen feeling did not ease, and he went to see the chest pain center of Wuhan Asian Heart Hospital. Upon examination, the doctor found that the coronary arteries had been blocked by a thrombus, and the diagnosis was acute myocardial infarction. Experts urgently opened the blood vessels, and Mr. Wang's life was saved. Mr. Wang had high blood pressure earlier, and the doctor speculated that vascular plaques had formed. This time my heart attack was caused by severe blood vessel constriction due to the low temperature in the morning exercise in winter. Fortunately, the rescue was timely.
"Near the Spring Festival, especially in the morning and evening, the temperature continues to drop. Many sports people still insist on getting up early and doing morning exercises. Every winter, the outpatient clinic will treat many citizens with sports problems." Professor Dai Yangyang of Wuhan Asian Heart Hospital emphasized that especially those with cardiovascular fragility, Winter morning exercises should not be greedy early.
"Due to the sudden drop in temperature in winter, people's ability to adapt is poor, and blood vessels are susceptible to contraction due to cold stimuli, especially in the early morning. After a night's sleep, the blood viscosity is high and the resistance to blood circulation increases. If you do a lot of exercise, you will endanger your life. "Dai Yangyang reminded that no matter the elderly or young people, exercise should be gradual, and time and content should be selected according to their ability, it is best to choose a soft exercise, should not exercise too much. Before winter sports, warm-up must not be less, and it must be fully in place, otherwise it is likely that because of low temperature, human muscles stretch less, joints are stiffer, causing muscle strains and joint sprains.
