Abstract:Aim To study the distribution feature on pulse pressure and the influence of the pulse pressure in patients with cerebral apoplexy in northern rural village. Methods Acohort study was carried out in a nature population(aged ≥35) of total 41 676 subjects in rural village of Liaoning province with blood pressure measurement in 2004.The frequency on different sex,age,level of blood pressure and the distribution feature of cerebral apoplexy in different pulse pressure levels were analysed. Result(1) The high frequency is 40~49 mmHg in different sex.(2)Frequency of high pulse pressure increased with blood pressure,the high frequency is 40~49 mmHg on normotensive,50~59 mmHg on BPI,70~79 mmHg on BPⅡ,and 80~89 mmHg on BPⅢ. There is no difference on different sex.(3)Frequency of high pulse pressure increased with age.(4)After correcting other factors,the prevelence rate is increased in pulse pressure 60~69 mmHg,and in no relation with systolic blood pressure. Conclusion Frequency of high pulse pressure increased with age or blood pressure.Pulse pressure 60~69 mmHg is an individual risky marker of cerebral apoplexy.
