Do you know about stroke? There has never been a disease that can make a person lose the dignity of life in an instant like a stroke: crooked mouth and eyes, numbness of limbs, or even paralysis in bed …… Stroke is scary, but there are still many misconceptions in stroke prevention and treatment. Many people think that stroke is a disease of the elderly, I am young, and my ancestors did not have such a disease, my blood pressure is not high, I live a very careful life, and I have a physical examination every year, so I am sure I will not have a stroke. In fact, 1 in 6 people worldwide will suffer a stroke in their lifetime, 1 in 2 seconds, 1 in 6 seconds will die from a stroke, and 1 in 6 seconds will be permanently disabled by a stroke. Stroke can occur at any age during a person’s lifetime, and its onset does not discriminate between sexes or ages. The average age of stroke onset in China is 66 years, 10 years earlier than in white Americans. Most stroke patients have no warning before the onset of stroke, and less than 1/3 have a history of transient ischemic attacks. Stroke screening is a comprehensive process. In this process, cerebrovascular and carotid examinations are only part of the process, and the onset of stroke depends on whether it has risk factors. Disease factors include hypertension, diabetes, heart disease, and of course, dyslipidemia and others. Patients often say that carotid artery examination is equal to stroke screening, and that a stroke will occur if there is plaque in the carotid artery. In fact, this statement is inaccurate. Carotid plaque is only one risk for stroke. It is the stability of the plaque and whether it causes significant luminal narrowing that is the key to carotid plaque secondary to brain attack. So don’t be nervous even if you have carotid plaque; it doesn’t necessarily mean stroke. Aspirin can prevent any stroke. Aspirin use in China is much lower than abroad, currently 14% in the general population and 50% in the US. The aspirin recommended by clinical doctors varies from person to person and is certainly not for anyone. Studies in the United States point out that it is appropriate for people who have already had a heart attack, women over 45 years of age, and people with multiple risk factors and a high risk of future cardiovascular disease. However, it is best not to use aspirin in the following people: people with very high blood pressure that cannot be easily controlled; people with bleeding disorders; and people with a family history of brain hemorrhage. The US national guidelines also state that stroke prevention and control measures are comprehensive and that aspirin is only one part of prevention. Although aspirin is important, you should not forget to take antihypertensive, lipid-regulating, and blood sugar-lowering medications as prescribed by your doctor; these are also important measures.
