The road to health is heart-pounding.

The hot summer has arrived. In addition to the unbearable heat, there is a huge risk: high temperature will make the death rate of cardiovascular and cerebrovascular diseases soar. This is not an alarmist. If you don't pay attention, you will really die! Why does high temperature increase the mortality of cardiovascular and cerebrovascular diseases? It is found that when the temperature is ≥35℃ for two days or more, the risk of sudden death will increase by 16%, and the high incidence time is usually concentrated at 3~5 pm. The main reason is: 1, the higher the temperature of human body's heat dissipation function, the expansion of blood vessels on the body surface, the increase of skin blood flow, the decrease of heart and brain blood flow, which is easy to lead to ischemia. 2, sweating is high, sweat will flow much, and a lot of water in the body will evaporate through sweat, which will thicken the blood in the body, easily block blood vessels and cause myocardial infarction. 3. The heartbeat and blood flow speed are accelerated. When the temperature is high, the internal circulation of human body will be disordered, the sympathetic nerve will be excited, the heart rate will be accelerated, the coronary artery will contract, the heartbeat and blood flow speed will be accelerated, which will increase the oxygen consumption of myocardium and increase the burden on the heart. Patients with hypertension, hyperlipidemia, coronary heart disease and other diseases have plaques and deposits in their blood vessels, which are more likely to block blood vessels at high temperature, causing sudden symptoms such as myocardial infarction and cerebral infarction, leading to accidents. Therefore, the elderly and patients with cardiovascular and cerebrovascular diseases must pay special attention in high temperature weather! Pay attention to these early warning "small signs". Although sudden death is sudden, there are always some clues before the accident. ? Chest pain: there is squeezing pain or tenderness behind the sternum or precordial area, which radiates to the left shoulder and left upper arm, and the pain lasts for 3~5 minutes. If the pain is severe and frequent, it may indicate myocardial ischemia. ? Sore throat: If the throat is not inflamed, but it suddenly hurts, accompanied by palpitation, chest tightness, sweating and other manifestations, it may be acute myocardial infarction, especially patients with hypertension, coronary heart disease, diabetes and other diseases, you must go to the hospital quickly. ? Neck pain: shoulder, neck, chin, arms and other parts. Feel pain for no reason, probably because of heart ischemia, so you need to pay attention. ? Special attention: such as palpitation, shortness of breath, dyspnea, nausea, vomiting, etc. Sometimes accompanied by unexplained sweating on the back, neck, scalp, palms and soles, it is best to rest on the spot and call 120 in time. Don't move the patient while waiting for 120 first aid to avoid violent shaking and vibration of the head. Try to let the patient lie on his side, unbutton his collar and keep the respiratory tract unobstructed. Those with dentures should be taken out. In short, as long as you have any of the above symptoms, you should pay attention to them and go to the hospital if necessary. Of course, if you don't want to be pestered by death, you must be well protected at ordinary times. Beware of sudden death due to high temperature, and do these things well at ordinary times: patients with cardiovascular and cerebrovascular diseases want to "cool down" cardiovascular and cerebrovascular diseases, remember these points. 1, don't suddenly turn around. Patients with cardiovascular and cerebrovascular diseases don't "suddenly turn around" in their lives to avoid accidents; Also avoid actions that require sudden exertion, such as playing badminton, playing basketball and getting up suddenly. 2, maintain good living habits, to work and rest regularly, it is best to take a nap at noon every day, and go out to exercise after dinner. We should also avoid excessive fatigue and mental stress, quit smoking and limit alcohol, eat less food stalls and drink less cold drinks. 3, to add more water, you need to add 2000~3000 ml of water every day, properly replenish electrolytes, and take a water cup with you when you go out to drink water; People who exercise should make up 990 ~ 1250ml for every weight loss 1kg after exercise. Don't drink a lot of water in a short time, especially ice water, and drink less sweet drinks and alcoholic drinks at ordinary times. 4. The temperature difference between indoor and outdoor is too large. When the room temperature exceeds 30℃, or when you feel very hot, you should turn on the air conditioner to avoid heatstroke. However, you should pay attention to the indoor and outdoor temperature difference as far as possible within 8℃, and also pay attention to opening the window every few hours for ventilation, so as to avoid excessive temperature difference and induce myocardial infarction or cerebral infarction. But don't blow the air conditioner immediately after sweating or taking a hot bath, and don't blow the air conditioner directly at the air outlet. 5, can not stop taking drugs at will, the condition should be treated in time, such as atrial fibrillation, which is more likely to form thrombosis and cause stroke, and thrombotic diseases are more likely to occur in summer. Therefore, patients with atrial fibrillation should insist on taking anticoagulants every day under the guidance of a doctor and should not stop taking them at will. In addition, patients with hypertension can't stop taking drugs on their own, so the dosage must be adjusted under the guidance of a doctor. In short, summer is the high incidence of sudden death, and patients with cardiovascular and cerebrovascular diseases must be well protected. It doesn't matter on such a hot day, so don't go to the sun. If you get sunburned, you will get heatstroke and even die suddenly! I'm just asking if you're afraid?
