老年高血压病动态血压与左室肥厚临床分析

Ambulatory blood pressure in elderly paints with hypertension and left ventricular hyperbophy in clinical analysis

目的：分析老年高血压病患者动态血压参数与左室肥厚（1vh）的关系。方法：对256例老年（≥60岁）高血压病患者依据是否伴有左心室肥厚分为左室肥厚组（1vh）与不伴有左室肥厚（n1vh）组，进行24h动态血压（abpm）检测。比较两组间动态血压参数与左室肥厚的关系。结果：（1）1vh组与不伴有1vh组比较，24hsbp、24hpP、dsbp、nsbp、bpf,bp1、1vmi差异有显著性（P〈0．01或0．05）；（2）1vh组以非杓型血压为主，占75％，而不伴有1vh组，以杓型血压为主，占79．41％；（3）lvh组lvmi与24hsbp、24hpp、dsbp、nsbp、sbp1正相关（r=0．477～0．795，P〈0．001），与sbpKdbpf负相关（r=-0．358，-0．289，P〈0．01）。结论：老年高血压病左室肥厚的发生与sbp、24hpp、sbp1和bpf相关。

Objective to observe the relationship between the parameters of ambulatory blood pressure and left ventricular hypertrophy （lvh）in elderly patients with hypertension. Methods ambulatory blood pressure monitoring （abpm） was performed in 256 cases of hypertension, which were divided into lvh group or non- 1vh group by the echocardiography, observe the relationship between the parameters of abpm and lvh. Results （ 1 ） 24hsbp, dsbp, nsbp, bph 24hpp, bpf and lvmi were significantly increased in the group with lvh and that in the group without lvh （p〈0.01 or 〈0.05）. （2） patients with non-dipper type hypertension were 45 cases （75%）in 60 patients with lvh. patients with dipper type hypertension were 54 cases （79.41%） in 68 hypertension patients with non-lvh. （3）by regression analysis in group lvh, the 24hsbp, 24hpp, dsbp, nsbp and sbpl had significant positive correlations with lvmi （r-r-0.477~ 0.795, p〈 0.001）, while sbpf and dbpf had remarkable negative correlation with lvmi （r=-0.358, -0.289, p〈 0.01 ）. Conclusion the occurrence of left ventricular hypertrophy in elderly patients with hypertension was related with sbp, 24hpp, sbpl and bpf.
