Abstract:
Objective To observe the influence of pulse pressure on renal injury in patients with essential hypertension (EH).Methods Two hundred and twenty-nine patients with mild-to-moderate EH completed 24 h ambulatory blood pressure monitoring.The patients were divided into 2 groups according to 24 h mean pulse pressure (MPP):EH 1 (24 h MPP ≥ 60 mmHg,1 mmHg =0.133 kPa) group (128 cases) and EH2 (24 h MPP ＜ 60 mmHg) group (101 cases).According to 24 h urine microalbumin and biochemical determination of renal function,the influence of pulse pressure on kidney function was observed and compared.Results The 24 h mean systolic blood pressure (MSBP) and 24 h MPP in EH1 group were significantly higher than those in EH2 group [(156.20 ±6.11) mmHg vs.(143.67 ±5.46) mmHg,(69.09 ±5.87) mmHg vs.(51.15 ±7.15) mmHg] (P ＜0.01),the 24 h mean diastolic blood pressure (MDBP) in EH2 group was significantly higher than that in EH1 group [(92.52 ±5.93) mmHg vs.(87.11 ± 5.52) mmHg](P＜ 0.01).The 24 h urine microalbumin in EH1 group was significantly higher than that in EH2 group [(104.80 ± 24.25) mg vs.(91.29 ± 24.03) mg] (P ＜ 0.01).There was positive correlation between 24 h MPP,24 h MSBP and 24 h urine microalbumin (r =0.259,0.201,P ＜ 0.01),and there was negative correlation between 24 h MDBP and 24 h urine microalbumin (r =-0.180,P＜ 0.01).Conclusion The 24 h MPP is closely related with the renal injury which is caused by high blood pressure in patients with EH.
