原发性高血压患者脉压与心肌梗死关系探讨

Relationship between pulse pressure and myocardial infarction(MI) with essential hypertension

目的 探讨原发性高血压患者脉压与心肌梗死之间的关系。方法 应用动脉血压监测系统观察 16 4例原发性高血压患者 ,根据平均脉压将患者分为两组 ,A组平均脉压 4 0～ 5 5mmHg,B组平均脉压 >5 5mmHg,观察3年内两组心肌梗死发生率。结果 B组心肌梗死发生率明显高于A组 ,差异有显著性意义 (P <0 0 1)。结论 原发性高血压患者脉压高者心肌梗死发生率高 。

Objective To investigate the relationship between pulse pressure and myocardial infarction (MI) with essential hypertension patients.Methods 164 patients were observed by ambulatory blood pressure monitor(ABPM).They were divided into 2 groups according to mean pulse pressure.A group, mean pulse pressure was 40～55mmHg, B group, mean pulse pressure was over 55mmHg.The ratio of MI in two groups was observed in 3 years.Results The ratio of MI in B group is higher than in A group′s,there is significantly difference in two groups (P<0.01).Conclusion The ratio of MI is high in the essential hypertension patients with high pulse pressure,the medicine that can decrease PP should be chosen to prevent MI.
