【摘要】 目的:观测高血压病(EH)患者的主动脉根部内径(AOD)、脉压(PP)及其他相关因素,结合文献分析其与左室肥厚间的关系,以指导临床治疗和预测血管意外发生的危险性。方法:对58例EH患者,应用超声心动图测量并计算其左室后壁厚度(LVPWT)、室间隔厚度(TVST)、AOD,用血压仪测量并计算其血压各参数值;根据测算结果将本组58例分为左室肥厚组和无左室肥厚组,并将相关数据进行组间统计学比较。结果:两组间比较,年龄、病程、脉压(PP)、收缩压(SBP)及AOD值有显著性差异(P<0.01),而舒张压(DBP)和平均动脉压(MAP)值无明显差异(P>0.05)。结论:PP增大及AOD增宽与左室肥厚呈正相关;PP在高血压左室肥厚中起重要作用,早期发现有利于心脑血管疾病的防治。更多还原

【Abstract】 Objective:To investigate the aortic dimension(AOD),pulse pressure(PP) and other related factors in patients with essential hypertension and to analyze their relations with Left ventricular hypertrophy(LVH) so as to direct the clinical treatment and predict the unexpected danger developed in blood vessel. Methods:58 patients with essential hypertension were examined with echocardiography and their LVPWT,TVST and AOD were obtained through calculation.According to the results,all patients were divided into LVH group and non-LVH group,and the corresponding data were compared by means of statistics between the two groups. Results:There were considerable differences in the parameters of age,course of disease,PP,systolic blood pressure(SBP) and AOD(P<0.01) between the two groups,while there were no obvious distinction in those of diastolic blood pressure(DBP) and MAP (P>0.05).Conclusion:The increase of PP has an effect on LVH and the widening of AOD.Early discovery is helpful to the prevention and cure of blood ressel disease of the heart and brain.更多还原
