Types of Stroke
中风的类型
First, it's important to understand what a stroke is. The most common type is called ischemic stroke. This is when a blood vessel supplying blood to the brain is obstructed by fatty deposits in the vessel lining, which is known as atherosclerosis. The ASA says about 87% of all strokes are ischemic in nature.
首先,了解中风十分重要。最常见的一种类型叫做缺血性中风。当为大脑供血的血管被血管壁中的脂肪沉积物阻塞时(也被称为动脉粥样硬化),就会引起这类中风。美中风协会表示,87%的中风案例都是缺血性的。
Hemorrhagic strokes, which comprise about 13% of stroke cases, result when a weakened blood vessel ruptures – most often the result of untreated or poorly treated high blood pressure – causing bleeding into the brain. The blood builds up and compresses the surrounding brain tissue, causing tissue damage and cell death.
出血性中风约占中风案例的13%,是由血管破裂力减弱(通常是高血压未经治疗或治疗不当所带来的结果)导致脑出血所致。血液积聚并压迫周围的脑组织,导致组织损伤和细胞死亡。
In each case, the longer the condition lasts, the more damage occurs. Stroke specialists use the phrase "time is brain" – every second the stroke lasts, more brain cells are damaged and die.
在每种情况下,症状持续的时间越长,造成的伤害也越大。中风专家常说这样一句话“时间就是大脑”——中风每持续一秒,就会有更多的脑细胞受损并死亡。
