If you don't manage high blood pressure, the Korean Stroke Association presents five prevention methods that risk stroke more than two to four times

Oct 30, 2024

The Korean Stroke Association (Chairman Kim Yong-jae, Chairman Sungkyunkwan Medical University Kim Kyung-moon) emphasized the importance of preventing stroke and treating it within golden time by managing risk factors for stroke and recognizing stroke symptoms on October 29.

Stroke is a sudden cerebrovascular disease caused by a problem with cerebrovascular and is an essential critical emergency disease. When the blood vessels in the brain are clogged, it is caused by cerebral infarction (80% of all strokes), and when the blood vessels in the brain burst, it is caused by cerebral hemorrhage (20% of all strokes). Stroke is the fourth leading cause of death in Korea, and it is the number one cause of adult disability, with 110,000 to 150,000 new stroke patients annually. In Korea, which is on the verge of a super-aged society, the number of stroke patients is increasing rapidly, and the number of patients is expected to continue to increase as the elderly population increases. In particular, since stroke is directly related to the patient's life and sequelae, prevention and management are essential, and it is important to keep the golden time of treatment by remembering stroke symptoms and early-stage treatment.

The first thing that should be practiced for stroke prevention and treatment is the control of risk factors for stroke prevention.



Typical risk factors for stroke include age, high blood pressure, diabetes, hyperlipidemia, heart diseases such as atrial fibrillation, smoking, and drinking.

Hypertension is the most important risk factor for stroke, and failure to manage blood pressure can increase the risk of stroke by more than two to four times. When controlled by normal blood pressure, the risk of stroke can be reduced by about 40%. Diabetes can also double the risk of stroke, but lowering glycated hemoglobin by 1% can reduce the risk of stroke by 12%.



Hyperlipidemia is also a major cause of arteriosclerosis and a major risk factor for cerebral infarction. However, active hyperlipidemia management can reduce the risk of cerebral infarction by 30-40%.

Atrial fibrillation, an important risk factor for cerebral infarction, is a major risk factor that increases the risk of cerebral infarction more than five times if anticoagulants are not taken properly. Atrial fibrillation occurs at less than 0.5% of people under the age of 50, but the incidence rate reaches 10% when they are over 80 years old, and they are more likely to have heart disease, so they should be examined periodically. In addition, smoking cessation and abstaining from drinking are essential parts of preventing stroke. Among the risk factors for stroke, non-age risk factors can reduce the risk of stroke by 90% if they are diagnosed periodically and treated and managed appropriately.



The second is to reduce sodium (salt) intake and maintain a healthy diet. Excessive intake of sodium increases the amount of water in the blood and increases blood pressure, which can lead to abnormalities in whole blood vessels. The World Health Organization's recommended daily sodium intake is 2000mg (salt 5g), but the average sodium intake in Korea is 3600-4000mg (salt 9-10g), which is twice the recommended amount. In order to control sodium intake, it is recommended to use sour and savory spices such as vinegar, lemon, and sesame oil instead of salt, use low-salt marinade, and reduce soup or seasoning when cooking ramen and instant food. In addition, it is recommended to consume unrefined grains such as vegetables and fruits, brown rice, and whole wheat for daily meals, reduce the intake of processed foods, and frequently consume blue-backed fish.

The third is steady exercise. Regular exercise is an effective lifestyle in preventing stroke by lowering the risk of stroke by 2.7 times. If you exercise regularly, you can increase muscle mass and increase the insulin sensitivity of the muscle to absorb sugar into the muscle to control blood sugar, control blood pressure, and contribute to weight loss to reduce stroke occurrence. Therefore, it is recommended to plan a total of 150 minutes of exercise, at least 30 minutes a day, three to five days a week. If you start exercising for the first time, it's good to start with an intensity enough to talk to the person next to you during the exercise. If you don't have enough time to exercise, it is also helpful to use stairs, stretch, and walk a short distance in real life.

The fourth is to remember the symptoms of stroke. Stroke symptoms occur suddenly, and suspected stroke symptoms include facial paralysis, pronunciation disorders, unilateral paralysis, aphasia, ocular displacement, visual disturbance, severe dizziness, and severe headaches. Therefore, it is important to remember 'neighbor Son Bal-Seon' in normal times.

Neighboring Son's eye line is ▶Neighbor: If you can't laugh (facial paralysis) ▶ Hand: If you can't extend your hands forward or if you have no more strength in one arm and leg (lateral paralysis) ▶ Foot: If your pronunciation is slurred or you can't communicate (acute dysphonia, aphasia) ▶ Eye line: If your eyes are on one side (eye deflection), etc.

If any of these symptoms are abnormal, visit the stroke center immediately through 119.

The fifth is to remember the golden time of stroke treatment. The golden time for stroke, especially cerebral infarction, is 4.5 hours after symptom onset. 4.5 hours is the time when intravenous blood-only release, the first of the early-stage treatment for cerebral infarction, can be administered. If a large cerebrovascular is blocked, you will undergo an intraarterial thrombectomy. Intraarterial thrombectomy is recommended to be received within 6 hours of symptoms, but it can be performed up to 24 hours of symptoms depending on the cerebral infarction lesion identified in the brain image. Quick treatment increases the probability of having a good prognosis in the future compared to stroke patients who do not. Therefore, if stroke symptoms occur, it is important to visit the hospital immediately and receive early-stage treatment.

October 29 is the annual "World Stroke Day" designated by the World Stroke Organization.

Since its foundation in 1998, the Korean Stroke Association has been active in stroke-related fields such as treatment, education, research, policy, promotion, and YouTube channel operation, and continues to establish a medical system and prepare medical guidelines for standardized quality treatment of stroke patients.

On the occasion of World Stroke Day, the Korean Stroke Association said "Stroke is a preventable and overcome disease. It is important for a healthy retirement to manage risk factors regularly, and to immediately report stroke symptoms to 119 and visit a hospital to receive treatment within golden time. " In addition, the Korean Stroke Association said "Receiving treatment quickly even for a minute and a second within the golden time is directly linked to the prognosis. Therefore, if symptoms occur after remembering the symptoms of stroke, you should immediately report them to 119 and visit the stroke center" he advised.
