Every winter is a period of high incidence of cardiovascular and cerebrovascular diseases. In recent days, the temperature in Qingpu has been continuously low and the body feels cold, and the number of patients with cardiovascular diseases in Qingpu's major hospitals has increased. The cold temperature causes the human sympathetic nervous system to be excited, and the blood pressure rises sharply in a short period of time, and the heart rate increases, which increases the burden on the heart and causes cardiovascular diseases. In particular, patients with underlying cardiovascular and cerebrovascular diseases should appropriately adjust their lifestyles and protect their brains to reduce the risk of related diseases.
Why is there a high incidence of cardiovascular and cerebrovascular diseases in winter?In the face of reporters' questions, Peng Fangqiang, the attending physician of the Department of Neurology of Shanghai Donglei Neurology, told reporters that when the weather is cold, the peripheral blood vessels constrict to reduce heat dissipation, blood pressure increases, blood flow is slow, blood viscosity increases, and then the load on the heart and brain increases, atheroplaque is easy to rupture, and coronary arteries are prone to spasm, thereby inducing cardiovascular and cerebrovascular diseases. In addition, when winter comes, citizens like to "tonic", and the calories in the diet increase, and the blood pressure and cholesterol levels also increase. In addition, because of the cold outside, everyone's daily activity and exercise are reduced, and the blood sugar and blood lipids of diabetic and hyperlipidemia patients are easy to lose control, increasing the risk of cerebral infarction. "High blood pressure is one of the most important risk factors for stroke, and it is also the fastest-changing factor. Only by measuring blood pressure can you know if your blood pressure is normal. Some people who originally had high blood pressure but did not pay attention to it will have higher blood pressure when the cold snap hits, and then cerebral hemorrhage, which is the case with several young patients with hypertensive cerebral hemorrhage who have been admitted to the emergency department recently. In addition, some patients who usually have high blood pressure and have good control may have poor control of the increase in blood pressure when the temperature drops, which is worse than the high risk of cardiovascular disease, and stroke may occur. Peng Fangqiang told reporters.
So how to actively prevent stroke when the cold snap hits?The doctor reminded the general public that first of all, they should do a good job of cold protection and warmth. As the saying goes, "Spring covers autumn frost, and there are no miscellaneous diseases." "Especially when the temperature difference between indoor and outdoor is large, if you must go out, you must wear warm clothes and shoes and socks, and the size of shoes and socks should be appropriate and loose, so as not to affect the blood circulation of the legs and feet. In particular, people with underlying cardiovascular and cerebrovascular diseases should not wash their faces and laundry with cold water, so as not to increase blood pressure due to cold stimulation. To exercise moderately, try not to get up in the morning to exercise, you can choose some aerobic exercises, such as tai chi, walking, Baduanjin, etc., the exercise time and intensity should not be too long and too strong. In addition, it is necessary to maintain a calm mind and pay attention to a reasonable diet, monitor blood pressure, blood sugar, blood lipids, etc. more frequently than usual, replenish more water, and find a doctor for follow-up and medication adjustment in time if there are abnormal or uncomfortable symptoms.
