Recently, many patients have come to the hospital and asked to be screened for stroke. On the one hand, this reflects the increasing awareness of the general public, which should be a good thing. However, as a medical worker in the daily clinical work, I have also experienced some misunderstandings of the people, which are listed below to further improve your scientific health care knowledge. Myth 1: I don’t know what stroke screening includes. Stroke screening includes the following components: screening for stroke risk factors, including lifestyle-related risk factors such as smoking, obesity, sedentary lack of exercise, unbalanced diet and heavy alcohol consumption; screening for disease-related risk factors, including hypertension, hyperglycemia, hyperlipidemia and heart disease; screening for cerebrovascular conditions, mainly non-invasive and relatively inexpensive vascular ultrasound examinations, including cervical Vascular ultrasound and transcranial Doppler ultrasound (TCD). CT or MRI of the head may be required in rare special cases, but is not a routine part of stroke screening and is not required in asymptomatic people. Myth 2: Ignoring lifestyle-related risk factors. In fact, you do not need to go to the hospital for screening, you can know it yourself. The key is to know whether you have the determination to take effective interventions to change your unhealthy lifestyle. Misconception 3, do not know the risk factors related to disease this part of the routine health check can do, many medical institutions to provide health screening is sufficient to cover this part, including blood pressure, blood tests, electrocardiograms, etc.. The most important thing is to detect chronic diseases (many of which are risk factors for stroke) and tumor diseases in a timely manner. Stroke screening does not cover tumor screening. Therefore, for screening risk factors, it is recommended that an annual health check-up is sufficient for middle-aged and elderly people, and there is no need to “push” for stroke screening. Myth 4: Stroke screening is only a cerebrovascular ultrasound. If a plaque is found on carotid ultrasound, you will be anxious and anxious, and if there is no problem, you will continue to live an unhealthy lifestyle, such as smoking and not exercising. In fact, carotid ultrasound is only a window that reflects the degree of atherosclerosis to a certain extent, and there is no 100% correspondence with the occurrence of stroke. The purpose of screening ultrasound is to detect stenosis in people who are at high risk of stroke and to choose more aggressive treatment, such as carotid endarterectomy or stenting for severe carotid stenosis, in order to prevent the possibility of a more serious stroke. But those with severe stenosis are, after all, a very small minority. To make it easier to understand, we can use the disease chain to compare the onset of stroke: lifestyle risk factors (smoking, obesity, alcoholism, sedentary lack of exercise, unbalanced diet, etc.) → disease risk factors (hypertension, hyperglycemia, hyperlipidemia, etc.) → vascular hardening, plaque, stenosis → cardiovascular disease (stroke, coronary heart disease). The top doctor treats the untreated disease, regardless of whether there is stenosis or not, and whether there is plaque or not, attention should be paid to control risk factors, including lifestyle risk factors and disease risk factors. In this way we can better understand the significance of stroke screening.
