脑梗（即缺血性脑卒中）是一种因脑部供血中断导致脑组织损伤的急症，若能早期识别并及时送医，可显著降低致残率和死亡率。快速识别脑梗的关键在于掌握“FAST”原则：F（Face，面部）——观察是否一侧面部下垂或口角歪斜；A（Arm，手臂）——检查是否一侧手臂无力或无法抬起；S（Speech，言语）——注意是否说话含糊不清或理解困难；T（Time，时间）——一旦发现上述任一症状，应立即拨打急救电话，争分夺秒送医。此外，突发剧烈头痛、视力模糊、行走不稳、意识模糊等也可能是脑梗的征兆。值得注意的是，部分患者症状可能短暂出现后自行缓解，这可能是“小中风”（短暂性脑缺血发作），仍需高度重视，尽快就医评估。记住，脑梗救治的黄金时间为发病后4.5小时内，越早治疗，恢复希望越大。
A stroke caused by a blockage in blood flow to the brain—known as an ischemic stroke or ‘brain infarction’—is a medical emergency. Early recognition and prompt treatment can significantly reduce disability and death. The key to rapid identification is the ‘FAST’ acronym: F (Face) – check for facial drooping or asymmetry; A (Arm) – look for weakness or inability to raise one arm; S (Speech) – listen for slurred or unclear speech or difficulty understanding; T (Time) – if any of these signs appear, call emergency services immediately. Additional warning signs include sudden severe headache, blurred vision, loss of balance, or confusion. Sometimes symptoms may briefly appear and then disappear—this is known as a transient ischemic attack (TIA or ‘mini-stroke’) and still requires urgent medical evaluation. Remember, the golden window for effective stroke treatment is within 4.5 hours of symptom onset; the sooner treatment begins, the better the chance of recovery.
