摘要
目的探讨老年高血压病患者动态脉压对左心室肥厚的影响。方法对59例老年高血压病患者进行动态血压(ABP)和超声心动图检查,分别测量ABP和超声心动图的各种参数。将24hPP≥60mmHg的患者29例列为A组,24hPP<60mmHg的患病30例列为B组。评价不同全天平均脉压(ABPP)对左室肥厚的影响。结果A组与B组比较,全天平均舒张压(24hABPD)和心脏射血分数(EF)明显下降(P<0.05和P<0.01),而全天平均收缩压(24hABPS)、左室重量指数(LVMI)和动脉僵硬度指数(ASI)明显增加(P<0.05)。结论脉压升高是老年高血压病患者左心室肥厚的重要危险因素。
[Objective] To evaluate the impact of ambulatory pulse pressure (APP) on left ventricular hypertrophy (LVH) in aged patients with essential hypertension. [Methods] 59 aged patients with essential hypertension were examined by ambulatory blood pressure monitor (ABPM) and echocardiography, the different index of ABPM and left ventricular mass index (LVMI) and Ejection fraction (EF) were measured. The patients were divided into group A (24 h PP≥60 mmHg, n =29) and group B (24 h PP<60 mmHg, n =30 ) according to 24 hPP. [Results] In the group A (24 h PP≥60 mmHg), ABPD and EF were significantly decreased (P <0.05 and P <0.01), while ABPS, LVMI and arterial stiffness index (ASI) were increased compared with the group B (24 h PP<60 mmHg) (P <0.05). [Conclusion] The increase in pulse pressure is the important determinant of LVH in senile patients with essential hypertension.
