Entering winter, the weather began to get cold.
The middle-aged and elderly friends around me heard that winter is a season with high incidence of cardiovascular and cerebrovascular diseases, He began to think about going to the hospital or community outpatient department to inject some fluid to dredge blood vessels. In order to prepare a good body through the cold winter, welcome the new year. Li a-po is no exception, as usual, like in previous years, go to the hospital to inject some fluid infusion, but unfortunately, recently heard that Li a-po legs and feet are not neat, speech is vague, diagnosis is acute cerebral infarction. So, the method of regular infusion to dredge blood vessels is still useless? In fact, this method of infusion to prevent cardiovascular and cerebrovascular diseases not only cannot prevent diseases, On the contrary, it increases a lot of risks. Let’s take a look at these misunderstandings. Three misunderstandings: Infusion Can Dredge Blood Vessels [Li a-po], who believe in regular infusion, believe that, Regular infusion of blood-activating drugs to dredge blood vessels, Can open up blocked blood vessels. Truth: In fact, the blocked blood vessels are opened, Mainly refers to some acute stroke or myocardial infarction patients can be thrombolytic through drugs, Or vascular stents, Rescue those tissues that are on the edge of ischemia. Of course, This time window is also strictly limited, It is usually effective only within a few hours. The whole process has nothing to do with transfusion of drugs for promoting blood circulation and removing blood stasis. Even in some acute patients, The doctor may give some blood circulation promoting and blood stasis removing drugs, It is usually only used as adjuvant therapy such as symptom improvement. At present, there is no good evidence that these drugs can reduce death or morbidity. However, patients in stable stage, The ischemic necrosis tissue is already necrotic, Tissues that can rebuild blood supply already have new blood vessels to supply blood. At this time, infusion of promoting blood circulation and removing blood stasis is even less meaningful for improving blood supply of various tissues. Myth 2: Infusion can relieve blood thickening and some people, It will be mentioned that because the blood is sticky, Asking for an infusion. Truth: The blood here is sticky, Usually blood viscosity, It is mainly determined by hematocrit (the percentage of blood cells per 100 milliliters) and fibrinogen. There are many factors affecting blood viscosity. And now it is believed that there is no clear relationship between blood viscosity and stroke or myocardial infarction. The result of blood viscosity cannot be used to require fluid infusion. Myth 3: The Long-term Effective Truth of Regular Infusion on Blood Vessels; The occurrence process of cardiovascular and cerebrovascular diseases is relatively long, Usually due to long-term poor control of hypertension, hyperlipidemia, etc., Forming an arterial plaque to block a blood vessel, Or plaque falling off to form thrombus blocking blood vessels, It will last for several years or even decades. It will not change due to the infusion once or twice a year. Even if the infusion has a dilating effect on local blood vessels, But a few days after the rehydration, the drug was metabolized, Nor will it have a long-term effect on damaged blood vessels. The risk of blind infusion is not only that, It is not pointed out that transfusion of blood-activating drugs will also increase the risk of many adverse reactions. Increasing the risk of bleeding: Blood-activating drug for patients with a tendency to bleed, Increases the risk of bleeding. Possible allergies: Due to composition problems or purification process and other reasons, A small number of people may develop allergies, Serious liver damage or dizziness, head swelling, etc. Side effects of infusion: For example, repeated intravenous infusion increases phlebitis, and the hospital environment increases the probability of cross infection. Thus, if there is no clear indication, it is recommended not to blindly infusion in order to prevent cardiovascular and cerebrovascular diseases. The correct prevention method, then, how should middle-aged and elderly friends who really want to prevent cardiovascular and cerebrovascular diseases do? 1. Know your physical condition and suggest that you go to a regular physical examination or medical institution to make an assessment of risk factors. To understand whether there are risk factors for cardiovascular and cerebrovascular diseases. The examination includes at least blood pressure, blood sugar, blood lipid, arterial plaque examination, electrocardiogram, etc. 2. Actively treat the corresponding basic diseases. For patients who already have risk factors, Corresponding treatment should be carried out. Actively controlling risk factors such as blood pressure, blood sugar and blood lipid requires drug control to take drugs according to doctor’s advice and effectively monitor indicators. For patients with atrial fibrillation, go to a regular hospital and receive anticoagulant therapy (such as warfarin) after evaluation by doctors. For patients with carotid plaque, statins can be taken to stabilize the plaque, and intimal exfoliation or stenting can be performed in severe cases. …… 3. A balanced diet can appropriately add pumpkin, corn, sweet potato, potato and other foods to replace pure refined rice flour as staple food; Ensure that a meal has meat and vegetable, meat does not exceed the standard, and there are 3 ~ 4 kinds of vegetables; Salt control, oil reduction and sugar reduction, soy sauce, fermented bean curd, bean drum or some natural spices can be used for seasoning to avoid high salt, high fat and high sugar diet. 4. Adhere to regular exercise to remind middle-aged and elderly friends that when the weather is cold, blood pressure can be measured before exercise, and warm up for 5-10 minutes before exercise; The weather is cold, it is best to exercise indoors. If you want to go out for exercise, Preferably after 10 o’clock, It is accompanied or carried out in places with protective measures. Sports for the middle-aged and the elderly, Attention should be paid to moderate amount and do what one can. 5. To go to the hospital in time, the last thing to pay attention to is that if there are new discomfort such as dizziness, headache, chest tightness, chest pain, palpitation, etc., or if the original discomfort suddenly worsens, one must go to a regular hospital for diagnosis and treatment so as not to delay the illness.
