摘要
目的 :研究老年高血压病患者脉压与左室舒张功能的关系。方法 :对 2 4 5例老年高血压病患者进行测压和超声心动描记检查 ,按平均动脉压 (MBP) <113mmHg和MBP≥ 113mmHg分为二组 ,再以脉压 (PP)≤ 6 0mmHg ;6 1～ 80mmHg;81～ 10 0mmHg ;>10 0mmHg分为四个亚组 ,并进行左室舒张功能检测 ,包括A峰流速 ,E峰流速 ,A/E ,左室等容舒张时间 (LV IVRT)。结果 :①MBP相同时 ,随着脉压的增加E峰差异不显著 ,而A峰、A/E、LV IVRT逐渐增大 ,且各组间差异有显著性 (P <0 .0 1)。②PP相同时 ,MBP〈113mmHg与MBP≥ 113mmHg两组间左室舒张功能各指标差异无显著性 (P >0 .0 5 ) ,而MBP≥ 113mmHg组的SBP、DBP均高于MBP>113mmHg组 (P <0 .0 1)。结论 :老年高血压病患者的左室舒张功能与PP关系密切 。
Objective:To study the relationship of pulse pressure (PP) and left ventricular diastolic function.Methods:Blood pressure and cardiographies were measured in 245 old aged patients with hypertension. They were divided into two groups according to mean blood pressure (MBP)<113 mmHg or MBP ≥113 mmHg(1 mmHg=0.133 kPa), then sub divided into four pulse pressure (PP) groups (PP≤60mmHg, 61～80 mmHg, 81～100 mmHg and>100 mmHg).Results:①When the patients` MBP were nearly the same level, with increasing PP, peak E had no significant difference (P>0.05), while E?A/E?LV IVRT decreased (P<0.01). ②Of groups MBP <113 mmHg and group MBP ≥113 mmHg, when the patients' PP were nearly the same level, their E?A/E?LV IVRT had no significant difference (P>0.05). However, systolic blood pressure (SBP), diastolic blood pressure (DBP), MBP of group MBP≥113 mmHg were higher than group MBP <113 mmHg (P<0.01).Conclusion:PP variability significantly relates to left ventricular diastolic function in old aged patients with hypertensive disease.
