The study of related factors of pulse pressure in elderly patients with essential hypertension

Objective To expore the relationship between the related factors and pulse pressure (PP) of the elderly patients with essential hypertension (EH).Methods A retrospective investigation of 309 hospitalized patients with EH (male 185 cases, 124 cases of women) from 2003 to 2007 were performed, In accordance with PP≤ 60 mmHg, 60 PP≤100 mmHg,PP 100 mmHg,the patients were divided into 3 groups.In each group,the correlation of PP with sex,hypertension course, body mass index (BMI) , SBP,DBP, blood glucose, blood lipids, LVMI, EF, FS, carotid artery plaque were annalyzed.Results There was no correlation of PP with the BMI, blood glucose, triglyceride (TG) , cholesterol (TC) , low density lipoprotein (LDL) (P 0.05) ;There were positive correlations of PP with age, hypertension course, SBP, LVMI, carotid artery plaque, EF(r =0.25,0.23,0.48, 0.65,0.69, 0.31, P all 0.01) , while there was negative correlation of PP with DBP, FS, high-density lipoprotein ( HDL) (r = - 0.90, - 0.35, - 0.22 ,P all 0.01).Conclusion There is correlation of PP with age, duration of hypertension, SBP, DBP, EF,FS, HDL, LVMI, carotid artery plaque
