关于心房颤动和沉默卒中的事实

像所有笔画一样，当大脑的氧气供应的一部分被切断时，会发生沉默的行程。但其他类型的中风（仅对那些只是片刻）造成困难的症状，如浆料，下垂的面孔和身体一侧的瘫痪。在一个沉默的行程中没有发生这种明显的警告标志，因为后者倾向于影响控制言论和运动的大脑区域。相反，一个沉默的中风损失领域，负责执行职能 - 你做计划的能力，如计划，注意和问题解决，以及管理你的情绪。

Ischemic strokes当一个最经常形成在心脏的凝块时，发生在大脑中。一旦那里，它会阻断动脉并切断氧气。一种出血性脑卒中occurs when a blood vessel in the brain bursts. The blood that pours out damages brain cells and causes dangerous pressure to build. Atransient ischemic attack (TIA)，A.K.A.迷你中风，具有中风的所有症状，但它只持续短时间，没有永久性损害。然而，TIA是一个巨大的红旗，以至于您未来的完全吹风机很可能。

The jury’s still out on this one, says Laurence Epstein, M.D., system director of electrophysiology at Northwell Health in Manhasset, NY, a specialist in afib and other arrhythmias. Clots may be one cause, but not the only cause, especially in people with afib, who may have blood vessels that don’t work as they should. This can make them more prone to blockages, such as those caused by atherosclerosis (plaque buildup) in the brain’s network of arteries, leading to chronic inflammation in the brain, which may also play a role. “Likely one answer does not fit all cases,” says Dr. Epstein.

You don’t have to have afib to have a silent stroke. About one-quarter of people 80 and older will have one or more silent strokes, and for every full-blown stroke documented, researchers estimate 10 silent strokes occur. But because silent strokes have no noticeable symptoms, it’s unlikely you or your doctor will know you had one—making an accurate tally difficult to do. Cardiologist Andrew Freeman, M.D., of National Jewish Health in Denver, says they’re often diagnosed when you get an MRI of your brain for unrelated reasons, and your doctor notices the telltale brain lesions left by strokes.

Silent strokes may not cause the devastating harm of a full-blown stroke (like speech and language problems, weakness, paralysis, and other major consequences that can leave you disabled and in need of ongoing care). However, silent strokes may increase your risk of a larger stroke, and if they continue to occur, the damage they cause will accumulate, boosting your chances of dementia and other types of cognitive impairment. Also, they’re not always完全无声。埃埃斯坦博士“但如果你不能认为你习惯的方式，那么你的症状可能不是戏剧性的。”

That will vary from person to person, and depend on where the strokes occur in the brain and just how small they really are. Sometimes, other parts of your brain can take over for the parts lost to stroke, so you don’t notice what’s been lost. In other cases, the brain damage may build up very gradually before it becomes obvious. “The changes are so subtle that you don’t see them,” says Dr. Epstein. “But someone who hasn’t seen you in two years may notice a dramatic difference.”

也许不完全。抗凝血药物（血液稀释药物）是针对AFIB的人们的所有类型中风的第一个，因为它们有助于预防凝块并显着降低行程的风险。但抗凝血剂可能无法提供相同的防止沉默笔画水平 - 更多的证据表明凝块不是唯一的罪魁祸首。最近的研究发现，5.5％的疗程良好的AFIB患者的新脑损伤，大多数由沉默的行程引起的。这可能有助于解释为什么AFIB的人更容易发展认知障碍和痴呆症，即使他们没有完全吹嘘。

弗里曼博士说他汀类药物，用于降低胆固醇的药物，可能有助于减少沉默的冲程，因为它们会降低炎症。Epstein博士补充说炎症的迹象，如升高的C反应蛋白水平，可以帮助预测您具有沉默中风的风险。但两位医生再次强调抗凝血治疗对AFIB的人的重要性。“抗凝血剂非常显着降低您有任何中风的风险，”弗里曼博士说。即便如此，爱普斯坦博士说，只有一半的人带着AFIB服用抗凝血剂。为什么？可能因为血液稀释剂不会影响患者的感觉，并且它们会导致过度出血。

pl！每周至少锻炼150分钟 - 甚至不快递步行数量！吃心智饮食。选择新鲜水果，蔬菜，全谷物和其他植物的食物。你不必全面素食，但是削减了脂肪的肉。选择瘦肉和鱼。换橄榄油的换黄油和人造黄油。限制盐以保持血压下降。并且，尽一切努力戒烟。这种健康黑客攻击减少了你的沉默笔画的几率，并使生活方式变化的风险几乎是零！“ Dr. Freeman says for added encouragement.
