Recently, the temperature has dropped sharply. Under low temperature and cold wave, the incidence rate of cardiovascular and cerebrovascular diseases will increase. Research has found that the causes of death for many cardiovascular disease patients are related to weather changes, with a 41% higher mortality rate in winter compared to summer. Winter is a high-risk period for cerebrovascular accidents Wang Wei, director of the Neurosurgery Department at Donglei Brain Hospital, told reporters on the 26th that as people age, the elasticity of their blood vessels gradually weakens, especially in cold weather where blood vessels contract when exposed to cold stimuli, leading to an increase in blood pressure. For individuals with pre-existing hypertension, the risk of arterial aneurysm rupture increases. It is reported that cerebral aneurysm is an abnormal protrusion on the cerebral vascular wall. The cerebral artery wall is inherently weak, forming local bulges under continuous blood flow, like a bubble blowing up from the blood vessel wall. This "bubble" is a "ticking time bomb" hidden in the skull: when patients experience mental tension, emotional excitement, fatigue, lifting heavy objects, going upstairs, etc., it can induce an increase in blood pressure and lead to the rupture of cerebral aneurysms, causing subarachnoid hemorrhage. In severe cases, intracerebral hemorrhage may also occur, and the patient's life may be in danger at any time. Wang Wei shared a case this month where an elderly person suddenly felt severe headaches and fatigue during morning exercise, and then lost consciousness and fell to the ground. At the hospital, after a CT scan, the doctor diagnosed the patient with subarachnoid hemorrhage accompanied by ventricular hemorrhage. After further vascular imaging examination, the doctor confirmed that the cerebral aneurysm had ruptured and the situation was extremely serious. After interventional embolization treatment for the aneurysm and craniotomy for ventricular drainage surgery, the patient finally regained consciousness. In winter, there is a large temperature difference between indoors and outdoors, and frequent temperature changes can cause significant fluctuations in pressure on human blood vessels, exacerbating the possibility of aneurysm rupture. Regarding this, Wang Wei reminds the public to keep warm, have a balanced diet, exercise in moderation, and maintain a good mentality by regularly checking and taking medication on time. This expert suggests that when the cold wind blows, elderly people should try to avoid going out as much as possible to prevent blood vessels from contracting and causing insufficient blood supply to the heart and brain; When there is a large temperature difference, remember to dress appropriately, especially the head and hands, and don't let them freeze. Eat less high calorie foods in winter to prevent cholesterol and blood lipids from skyrocketing; Eat more meat, rice, fruits, and vegetables to keep blood vessels healthy. Wang Wei reminds that in winter, if the elderly move around every day, take a walk or do Tai Chi, their blood circulation will be much better. Don't exercise too vigorously when it's cold in the morning. Wait for the sun to come out and the temperature to rise before going out for activities. He reminded the public to regularly go to the hospital for check ups, especially for friends with cardiovascular and cerebrovascular diseases, to remember to take medication on time and not to change the dosage and frequency of medication by themselves. By doing these things well, the risk of developing cardiovascular and cerebrovascular diseases in winter can be greatly reduced. This expert suggests that if you feel something is wrong, such as a crooked face, unstable walking, or difficulty speaking, you should quickly seek help from a doctor. (New Society)
