Two days ago, a patient was sent to the hospital for emergency treatment due to a heart attack, but the family may not have responded properly and delayed a lot of time in between, so when the patient entered the emergency room, it was already very critical, and even though the doctors tried their best, they still couldn’t get the patient back from “death”. Although it is not uncommon to see patients with sudden heart attacks in hospitals, it is especially common in recent times, and there are often patients with cardiovascular and cerebrovascular diseases who are admitted to hospitals. Temperature change and cardiovascular disease are closely related! The temperature changes every day and every hour, we are used to it, but in the autumn and winter season every year, it is a dangerous period for the high incidence of cardiovascular diseases. Once the temperature drops drastically, our body will adjust itself, such as faster heart rate, higher blood pressure, increased heart pumping, etc. This series of physiological changes will increase the burden on the heart, and thus induce adverse events! Moreover, we also need to consider the sudden temperature difference stimulation, in daily life, you may have similar experience: “hot summer into the air-conditioned room, when taking a cold shower, a cold wind blowing at night, etc.”, this sudden sudden change in temperature, will make the sympathetic nerve suddenly excited, which is also the body’s normal stress response, when When the neuroexcitatory transmitters increase, the corresponding blood vessels of the patient will be spasmodically contracted continuously, blocking the normal flow of blood, if a normal person may not have any abnormal reaction, but for patients with cardiovascular disease whose blood vessels are already narrowed and blocked and severely ischemic, this change may play a role in “crushing the camel’s last straw This change is likely to be the “last straw that broke the camel’s back” for patients with cardio-vascular diseases, which may lead to adverse events. In the increasingly low temperature now, how should we avoid the danger? 1.Adjust your clothes at any time Please, when you go out, read the weather forecast, if it is sunny, then it is best to take into account the maximum and minimum temperature, if it is rainy, then try to wear more clothes, because the actual temperature of rainy days will be lower than the minimum temperature. 2, reduce physical activity The higher the intensity of the activity, the more blood oxygen energy needs to be consumed, for patients with cardiovascular disease, in cold weather, should try to avoid high-intensity physical exercise, otherwise it is easy because of the imbalance of blood oxygen supply and demand and dangerous. 3, do not listen to rumors such as what to drink to warm up, which is actually a false surface perception, drinking can give the feeling of warmth because it can be our body heat quickly to the body surface, but in fact more important body heat instead of reducing.
