The temperature dropped sharply, and the 70-year-old man insisted on morning exercise, and danger came

"He often didn't listen to my advice. He suffered chest pain and sweating after morning exercises. Later I found out it was a heart attack!" Uncle Chen (pseudonym), who is over 70 years old, felt very regretful after listening to his wife's complaints.

According to weather forecasts, this strong cold air process has a wide impact range and a large temperature drop, which is likely to induce acute cardiovascular diseases related to low temperature exposure. The Department of Cardiovascular Medicine of Zhejiang Provincial People's Hospital treated four cases of acute myocardial infarction in two days.

It is dangerous to exercise early in the morning in the cold wind

"Old Chen, the sky is gloomy and cold. Don't exercise today, or wear more clothes and go out later!" "When you get up early, there are fewer people and the air is better. It's especially comfortable to run." "Then don't forget to take your medicine. I have to remind you every day!" Uncle Chen has the habit of morning exercises, but he always takes medicine lightly. On this day, he went out for a jog before 6 a.m., and danger came.

Uncle Chen, dressed in shorts, went outside without any exercise. The cool wind blew in his face and he couldn't help shivering. After running for less than 10 minutes, Uncle Chen suddenly felt chest tightness and chest pain...

"Didn't you go to the vegetable market?" His wife saw that Uncle Chen, who was sweating all over, came home earlier than usual after morning exercise and was also empty-handed, which was unusual for him. Uncle said that he felt unwell and might be tired, and he would be fine after a rest. After resting for more than half an hour, the discomfort did not ease, but became more and more serious, so Uncle had to tell his wife the truth.

"Hurry to the hospital!" Accompanied by his wife, Uncle Chen came to the hospital. Electrocardiogram and troponin test showed that he had acute myocardial infarction. Coronary angiography found that one of Uncle Chen's blood vessels was almost blocked. The doctor quickly placed a stent... Uncle Chen was out of danger.

Coincidentally, Mr. Zou (pseudonym), who is nearly 50 years old, was also infected. He had dinner with friends in the evening and drank a lot of wine. After dinner, he went outside and felt a little cold in his thin clothes. Late at night, he had chest pain, dizziness, and cold sweats. Mr. Zou, who had just laid down, felt something was wrong and rushed to the hospital. The results of the coronary angiography surgery showed that there were a large number of thrombus shadows in the middle section of the patient's right coronary artery. At this time, the patient's blood pressure dropped significantly... The doctor gave him fluid replacement, raised his blood pressure, and accelerated the speed of opening the diseased blood vessels.

Afterwards, the doctor learned that the patient had a history of smoking for more than 20 years. He believed that the hidden danger had already existed, and drinking and cold wind were just triggers.

As autumn and winter turn, prevent acute cardiovascular and cerebrovascular diseases

Wang Lihong, chief physician and director of the Department of Cardiology at Zhejiang Provincial People's Hospital, said that myocardial infarction, commonly known as "heart attack", is an acute heart disease, which generally refers to the blockage of the blood vessels (coronary arteries) that supply blood to the heart, leading to myocardial hypoxia and necrosis. Myocardial infarction occurs quickly and causes serious harm. The high-risk group is mainly middle-aged and elderly people, but the incidence rate among young people has also increased in recent years. Therefore, prevention and treatment are very important.

"Now is the transition period between autumn and winter, when cold air is frequent. Cold stimulation can excite the human sympathetic nerves, cause systemic vasoconstriction, increase blood pressure, increase myocardial oxygen consumption, and increase the risk of rupture of coronary atherosclerotic plaques. Cold can also induce coronary artery spasm, reduce coronary blood flow, and cause myocardial infarction. For example, the cold air has hit in the past two days, and the temperature has dropped significantly. For patients with coronary heart disease, they should be alert to the risk of myocardial infarction within a week of cold weather."

Wang Lihong suggested that, first, when cold air strikes, don't forget to put on more clothes, especially for middle-aged and elderly people with high blood pressure and heart disease, who should pay more attention to keeping warm;

Second, do not relax the treatment of related diseases. Many chronic diseases are often affected by the seasons. For example, patients with hypertension, diabetes, hyperlipidemia, coronary heart disease, etc. should take medicine as prescribed by the doctor, take medicine at regular times and in regular amounts, and do not stop taking medicine at will.

Third, the elderly get up early in the morning, and many of them have the habit of morning exercises. Elderly people with cardiovascular and cerebrovascular diseases should be reminded not to get up too early for morning exercises when it is cold, especially when cold air hits. Data show that one of the characteristics of hypertension in Asians is that hypertension is more common in the early morning, and the morning is also one of the times when the incidence of diseases such as myocardial infarction and cerebral infarction is higher. Therefore, it is best to start morning exercises when the temperature rises. At the same time, when going out on cold days, especially for the elderly, do warm-up exercises and wait until the muscles are warm and no longer stiff before going out.

"We should pay attention to the warning signs before acute myocardial infarction. Most patients with acute myocardial infarction have early warning signs before the onset of the disease, including fatigue, chest tightness, frequent angina pectoris, difficulty breathing, accompanied by nausea, vomiting, sweating and other symptoms. Patients suspected of acute myocardial infarction should be sent to the hospital in time." Director Wang Lihong reminded.
