The key to golden time shooting… “Big impact on prognosis”
Thrombolysis upon arrival at hospital within 4 hours and 30 minutes
According to the medical community on the 12th, when the temperature drops and the daily temperature difference increases, the blood vessels in the body rapidly contract and blood pressure rises, increasing the risk of cerebrovascular disease. If you suddenly have slurred speech, no speech, headaches, dizziness, or visual disturbances, it may be a symptom of a stroke.
In particular, in the case of acute cerebral infarction in which a cerebral blood vessel is blocked, blood flow must be supplied by opening the blocked blood vessel as quickly as possible. It is most important to arrive at the hospital as soon as possible after symptoms of cerebral infarction occur. This is because if you go to the emergency room quickly, thrombolysis can be performed.
The reason why golden time is important in cerebral infarction is because once damaged brain tissue does not regenerate. If you do not receive prompt treatment after a stroke such as cerebral infarction occurs, the area of brain damage gradually grows from the center to the periphery over time.
If you need to go to a hospital that offers thrombolysis, it is best to call 119 and visit the hospital. Professor Jang said, “The injection can be administered within 4 and a half hours after the onset of acute cerebral infarction symptoms, and treatment should be started as soon as possible to ensure a good treatment prognosis, so you should arrive at the hospital as soon as possible after the onset of acute cerebral infarction.”
Thrombolysis is not the only treatment for patients with acute cerebral infarction. Among patients with acute cerebral infarction, the risk of bleeding increases when intravenous thrombolytics are administered, so some patients receive drug treatment. In this case, the patient is admitted to the stroke intensive care unit and their progress is carefully observed.
Professor Jang said, “After thrombolytic injection, other treatment methods such as additional intra-arterial thrombus removal procedure or emergency vascular bypass surgery may be considered depending on the area of the occluded blood vessel or the size of the cerebral infarction.”
Professor Jang said, “When the temperature changes suddenly, blood vessels constrict, heart rate increases, and the risk of developing a blood clot (coagulated blood clot) increases.” He added, “Be careful about keeping warm to avoid sudden changes in body temperature, and keep in mind underlying conditions such as blood pressure, diabetes, and hyperlipidemia. “You need to pay attention to managing your condition by controlling the disease, eating a healthy diet, and exercising regularly,” he said.

Interview Between the Time.news Editor and Professor Jang
Editor: Welcome, Professor Jang! Thank you for joining us today. The recent report highlighting the importance of “golden time” in treating strokes has garnered a lot of attention. Can you explain what you mean by “golden time”?
Professor Jang: Thank you for having me! The term “golden time” refers to the crucial time window after the onset of stroke symptoms, during which treatment can significantly improve outcomes. Specifically, in cases of acute cerebral infarction, thrombolysis—the process of dissolving the clot blocking blood flow—must be administered within four and a half hours of the initial symptoms appearing. This is critical because the sooner we can restore blood flow to the affected area of the brain, the better the patient’s prognosis.
Editor: That makes sense. What specific symptoms should individuals be aware of to identify a potential stroke?
Professor Jang: Great question. People should be watchful for sudden onset of symptoms such as slurred speech, inability to speak, severe headaches, dizziness, or visual disturbances. If any of these occur—especially in light of sudden temperature changes or physical strain—it’s essential to seek immediate medical attention.
Editor: You mentioned temperature changes increasing stroke risk. Can you elaborate on how and why this occurs?
Professor Jang: Certainly. When temperatures drop, blood vessels shrink, leading to increased blood pressure and a higher likelihood of blood clot formation. This is especially concerning for individuals with underlying conditions such as hypertension, diabetes, or hyperlipidemia. Therefore, I recommend that people take proactive measures to stay warm, particularly during colder months, and closely monitor their existing health conditions.
Editor: What should a patient do if they suspect they are having a stroke?
Professor Jang: If you suspect you’re having a stroke, the best course of action is to call emergency services immediately, such as dialing 119 in our region. Time is truly of the essence. Even if symptoms seem to diminish, it’s crucial to get evaluated by a healthcare professional who can assess your condition properly and initiate treatment if necessary.
Editor: Once a patient arrives at the hospital, what treatments do they potentially receive?
Professor Jang: The first step is usually thrombolysis, which should be administered as quickly as possible. However, if there are contraindications for thrombolysis, other treatments may be initiated. For example, patients might be monitored in a stroke intensive care unit where their progress can be observed closely, or alternative procedures like intra-arterial thrombus removal or surgical options could be considered depending on the severity and specifics of the case.
Editor: Are there lifestyle changes that patients could adopt to reduce their risk of stroke?
Professor Jang: Absolutely. Managing underlying health conditions is key. This includes adhering to prescribed medications, maintaining a healthy diet, and exercising regularly. Additionally, staying warm and avoiding sudden changes in body temperature can be beneficial, especially during extreme weather conditions.
Editor: Professor Jang, it’s been enlightening discussing such an important topic. Is there a final message you would like to share with our readers?
Professor Jang: Yes, I’d like to emphasize that awareness is the first step in prevention. Understanding the risk factors and recognizing the symptoms of stroke can save lives. Everyone should be proactive about their health and seek medical advice if they experience concerning symptoms. Thank you for bringing attention to this vital issue!
Editor: Thank you for your time and insight, Professor Jang. It’s been a pleasure speaking with you.
Professor Jang: Thank you! The pleasure is mine.
