脉压和脉压指数与血压关系的研究

目的研究脉压、脉压指数与血压之间的关系。方法将106例高血压病患者按血压水平分为高血压病1、2、3级组,并将62例健康体检者设为正常对照组,分别检测各组脉压、脉压指数。通过高血压病患者间及与正常人群的对比,获得不同分组高血压病患者脉压、脉压指数与血压之间的关系。结果高血压病组脉压明显高于正常对照组(P<0.01),脉压指数明显高于正常对照组(P<0.01);2.高血压病2级组和3级组脉压明显高于1级组(P<0.01),高血压病2级组脉压指数明显高于1级组和3级组(P<0.01)。结论脉压、脉压指数与血压关系密切,其中,脉压表现出随血压水平升高而持续升高的趋势;脉压、脉压指数作为临床评价心血管疾病发生的危险性的指标,具有一定的价值。

Study of the relationship between pulse pressure, pulse pressure index and blood pressure

Objective To study the relationship between pulse pressure, pulse pressure index and blood pressure in patients with essential hypertension（EH）. Methods 106 patients with EH were divided according to blood pressure level into mild blood pressure group, moderate blood pressure group and high blood pressure group. 62 subjeccts with normal were studied as normal controls. Results The pulse pressure, pulse pressure index in patients with EH were all significantly higher than it in the controls（P〈0.01）. The pulse pressure was significantly higher in moderate and severe EH patients than in the mild（P〈0.01）. The pulse pressure index was significantly higher in moderate EH patients than in the mild and severe（P〈0.01）.Conclusion There is a significant relationship between pulse pressure, pulse pressure index and blood pressure. Pulse pressure, pulse pressure index can offer useful parameters for cardiac function in patients with EH.
