Approximately 795,000 people suffer from stroke annually in the US. According to this estimate, 1 person gets a stroke every 40 seconds, and approximately 1 patient dies due to a stroke every 4 minutes. Acute stroke can be classified as ischemic, hemorrhagic, subarachnoid, cerebral thrombosis, and spinal stroke. About 80 to 87% of all strokes are of ischemic origin. Ischemic stroke is further divided into 5 subtypes: 1. Large-artery atherosclerosis. 2. Cardioembolism. 3. Small-vessel occlusion. 4. Stroke of other determined etiology. 5. Stroke of undetermined etiology. Risk factors of stroke can be divided into modifiable and non-modifiable. Modifiable factors are hypertension, diabetes, hyperlipidemia, tobacco use, alcohol and drug use, physical inactivity, and atrial fibrillation. Non-modifiable factors are age, sex, race, and genetics.
在美国,每年约有79.5万人罹患中风。据此估算,每40秒就有1人中风,每4分钟就约有1名患者死于中风。急性中风可分为缺血性、出血性、蛛网膜下腔、脑血栓形成和脊髓中风。所有中风病例中,约80%至87%源于缺血性。缺血性中风又进一步分为5种亚型:1. 大动脉粥样硬化。2. 心源性栓塞。3. 小血管闭塞。4. 其他明确病因的中风。5. 病因不明的中风。中风的风险因素可分为可改变和不可改变的两类。可改变因素包括高血压、糖尿病、高脂血症、吸烟、酗酒和吸毒、缺乏运动以及心房颤动。不可改变因素包括年龄、性别、种族和遗传。
