Now is the time when the heat is hard to retreat, and the turn of the day hot night cool, careful people will often find that the elderly are always difficult “high temperature” this hurdle, around the stroke of the father and mother-in-law more, busy parents hospitalization thing friends also more. So is the “high temperature” prone to stroke? Not many people know about it, so today we will talk about it. In fact, the impact of weather changes on stroke has long been observed, for example, the incidence of stroke in the cold north of China and Russia is significantly higher than in the south, the major hospital neurology department in winter is filled with patients with cerebral hemorrhage, etc. This is the case of low temperature, high temperature on the impact of stroke performance and how? 1, high temperatures are more likely to occur when the brain infarction, low temperatures are more likely to occur when the brain hemorrhage. The province “high temperature” is generally accompanied by “high humidity”, this climate is easy to make the human microcirculation vasodilatation, capillary bed a large number of open, the body sweating heat loss, loss of water, coupled with the elderly thirsty species dull response, do not know timely replenishment of water; In addition, the Summer easy to eat unclean video and diarrhea, so it is very easy to cause blood concentration, blood stagnation, blood viscosity increase, start thrombosis, leading to the occurrence of cerebral infarction. 2, high-temperature season, low blood pressure, easy to lead to insufficient intracranial blood perfusion and stroke. High temperature season, the elderly blood pressure tends to automatically fall, lower than in winter, coupled with the heat is easy to lose water, blood pressure is even lower, if you are still taking antihypertensive drugs (often), it is bound to cause lower blood pressure, higher and lower fluctuations. This is the reason why elderly people often get up suddenly in summer with black eyes, unstable standing, dizziness and faintness, and in severe cases, blankness and injuries on the ground. This happens after the blood pressure can not be adjusted back up in time, if not handled properly (such as blindly taking antihypertensive drugs, think of the patient support not to lie down, etc.), cerebral infarction will occur. 3. The risk of stroke increases when the temperature fluctuates, and the risk of ischemic stroke increases dramatically when the daily temperature changes by more than 5℃. Therefore, there are two annual peaks of cerebral infarction, i.e. between spring and summer and autumn and winter, and one daily peak, i.e. between 6:00 a.m. and 8:00 a.m. at breakfast. 4. Statistical studies have found that the older the age, the more obvious the onset of the disease is affected by temperature. In general, stroke onset is not significantly affected by temperature in people younger than 65 years old, while people older than 65 years old have an increased risk of developing stroke. This is related to the low adaptive capacity, increased brittleness of blood vessel walls, decreased diastolic capacity, and decreased neuromodulation in the elderly. Measures to cope with high temperature climate and reduce the occurrence of stroke 1. Test blood pressure and reduce the use of antihypertensive drugs appropriately. 2, summer and winter treatment, cerebrovascular disease is ultimately due to potential lesions in the cerebrovascular wall, before the summer, to an experienced hospital for a physical examination, if found that the blood vessel wall has plaque, become narrowed, to pay attention to, should be done early treatment. If you find plaque or stenosis in the blood vessel wall, you should pay attention to it and do it early. This will make it safer to spend the summer and even travel. 3, pay attention to the heat, research has found that the incidence of cerebral hemorrhage and cerebral infarction are low when Wendu is between 20 degrees – 24 degrees, Wendu is low or high, the incidence of cerebral infarction are higher, but cerebral hemorrhage disease is the lower the incidence of the higher the temperature. So please have the conditions of the family group for your parents who work all their lives and can not spare the money to install heating and air conditioning. 4, once the onset of the disease, the first time to the hospital with thrombolytic experience for emergency thrombolysis, may be a wonderful hand back. The time window is within 6 hours after the onset of the disease, the earlier the better. The sooner the better, the less chance of thrombolysis. During this period, you should never sit and wait, take other people’s antihypertensive medication without any reason, or let people who are dizzy lie down immediately. 5.Take medication according to the systematic treatment plan formulated by experienced doctors, including antiplatelet, antihypertensive, lipid regulating, sugar lowering, reasonable diet, drinking more water, physical exercise of humidity, changing medication and quitting bad habits. Do comprehensive treatment. 6, pay attention to the weather changes, in line with the weather changes, to maintain the stability of the body’s internal environment.
