近年来,中风的发病率和脑血管疾病引起的死亡率已明显下降。由于认识到高血压是中风的主要危险因素,并治疗高血压,减少了中风的危险性。除了高血压以外,引起中风的其它危险因素并不完全清楚。本文根据12年随访观察提出吸烟是引起各种中风的一个单独危险因素。中风发病率随年龄增长而增加,血栓性中风发病率比出血性中风高2～3倍。不论吸烟量多少,吸烟者比不吸烟者有较高的中风发病率,其患中风的危险性都是相同的。然而,大
In recent years, the incidence of stroke and mortality caused by cerebrovascular diseases have dropped significantly. Recognizing that high blood pressure is a major risk factor for stroke and treating high blood pressure, it reduces the risk of stroke. In addition to high blood pressure, other risk factors for stroke are not fully understood. Based on a 12-year follow-up, smoking is the single cause of stroke. The incidence of stroke increases with age, and the incidence of thrombotic stroke is 2 to 3 times higher than that of hemorrhagic stroke. Regardless of the amount of smoking, smokers have a higher incidence of stroke than non-smokers, and the risk of stroke is the same. However, big
