At the beginning of spring, everything is revived and vibrant, but spring cold is easy to return, changeable, a little carelessness, heart and brain disease. Therefore, it is very important to do a good job in the spring to prevent cardiovascular disease. First, to keep warm. Although the spring looks bright and warm, but the temperature is not high. Moreover, it is windy outside and there is a big temperature difference during the day. For patients suffering from cardiovascular and cerebrovascular diseases, this weather is the most dangerous. At this time, people often take off their thick winter clothes and put on relatively thin spring clothes, and they no longer cover up tightly when they go out like in winter; the heating in the living room stops and the windows are always opened for ventilation. As a result, the relative lack of warm still cold weather, the chance of getting cold than winter. The heart and brain lesions of the most sensitive blood vessels, a stimulus to spasm, a spasm on the infarction. So it is said to “spring cover”, “cover” is justified. The second is the time for outdoor activities. One is to be short, the second is to choose a sunny day without wind. Sweating during activities and getting cold after activities are common triggers for cardiovascular and cerebrovascular emergencies. Third, feel unwell to seek medical attention in a timely manner. Do not wait, carry, or delay. All of our cases of sudden cardiac arrest in the emergency room were successfully rescued because they came in time and called “120” when they felt sick, and generally arrived at the hospital within a few dozen minutes of the onset. If you hesitate a little, you may not have a chance if you are a few minutes late.
