摘要
目的探讨高血压患者脉压(PP)及脉压指数(PPI)对早期肾损害的指示作用。方法纳入80例经诊断证实为高血压合并肾损害的老年患者作为A组,同时选取60例仅诊断为高血压的老年患者作为B组,再随机抽取30例健康体检老年人作为C组。所有受试者均进行PP、PPI检测,并对A组患者早期。肾损害指标进行检测。结果A组中PP≥60mmHg(1mmHg=0.133kPa)及PPI≥0.5的患者分别占70.0%(56/80)、75.0%(60/80),明显多于B组的41.7%(25/60)、43.3%(26/60)和C组的26.7%(8/30)、23.3%(7/30),差异有统计学意义(P〈0.05)。A组中PP≥60mmHg患者的β2微球蛋白(β2-MG)、尿微量白蛋白(MAU)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)及半胱氨酸蛋白酶抑制剂C(Cys-C)分别为(13.23±3.22)mg/L、(56.6±13.2)mg/24h、(1.9±1.2)mmol/L、(2.6±1.2)mmol/L、(2.01±0.80)mg/L,与PP〈60mmHg患者的(12.03±2.32)mg/L、(42.7±123)mg/24h、(2.2±1.3)mmol/L、(2.9±1.3)mmol/L、(1.21±0.90)mg/L比较差异有统计学意义(P〈0.05),而血尿酸(SUA)、血肌酐(SCr)与PP〈60mmHg患者比较差异无统计学意义(P〉0.05);PPI≥0.5患者132.MG、SCr、MAU、LDL及Cys.C分别为(10.53±2.43)mg/L、(97±22)μmol/L、(52.5±12.4)me424h、(2.2±1.2)mmol/L、(1.91±0.90)mg/L,与PPI〈0.5患者的(14.00±2.15)me4L、(82±16)μmol/L、(40.7±11-3)mg/24h、(2.7±1.3)mmol/L、(1.23±1.10)mg/L比较差异有统计学意义(P〈0.05),而SUA、HDL与PPI〈0.5患者比较差异无统计学意义(P〉0.05)。结论高血压合并肾损害患者中PP≥60mmHg及PPI≥0.5的患者明显多于单纯高血压患者和健康体检者;PP及PPI可以作为高血压患者早期肾损害的预测指标,对该类患者需要密切关注其PP及PPI的变化。
Objective To observe the indicative function of pulse pressure (PP) and PP index (PPI) on early renal damage in patients with hypertension. Methods Eighty old aged patients with hypertension and renal damage were selected as group A, 60 old aged patients with hypertension as group B, and 30 old aged healthy people as group C. PP and PPI were examined in all groups, and early renal damage index was examined in group A. Results The rates of PP ≥ 60 mm Hg ( 1 mm Hg = 0.133 kPa) and PPI ≥ 0.5 in group A were significantly higher than those in group B and group C [70.0%(56/80) vs. 41.7% (25/60) and 26.7%(8/30),75.0%(60/80) vs. 43.3%(26/60) and 23.3%(7/30),P 〈0.05]. In group A, there were significant differences between PP ≥ 60 mm Hg patients and PP 〈 60 mm Hg patients in beta 2 microglobulin ( 132-MG), microalbuminuria ( MAU ), high-density lipoprotein ( HDL),low-density lipoprotein (LDL) and homocysteine protease inhibitors C (Cys-C) [ ( 13.23 ± 3.22) mg/L vs. ( 12.03 ± 2.32) mg/L,(56.6±13.2)mg/24 h vs.(42.7± 12.3) mg/24 h, ( 1.9± 1.2) mmol/L vs. (2.2 ± 1.3) mmol/L, (2.6 ± 1.2) mmol/L vs. (2.9 ± 1.3) mmol/L, (2.01± 0.80) mg/L vs. ( 1.21 ± 0.90) mg,/L,P 〈 0.05 ] ,but there was no significant difference in serum uric acid (SUA) and serum creatinine (SCr)(P 〉0.05). There were significant differences between PPI ≥0.5 patients and PPI 〈 0.5 patients in β 2-MG, SCr, MAU, LDL and Cys-C [ ( 10.53 ±2.43 )mg/L vs. ( 14.00 ± 2.15 ) rag/L, (97 ± 22) μ mol/L vs. ( 82 ± 16) μ mol/L, (52.5± 12.4) mg/24 h vs. (40.7± 11.3 ) mg/24 h, (2.2 ±1.2) mmol/L vs. (2.7 ± 1.3) mmol/L, (1.91 ± 0.90) mg/L vs. (1.23 ± 1.10)mg/L,P 〈 0.05 ],but there was no significant difference in SUA and HDL (P 〉 0.05 ). Conclusions The rates of PP ≥ 60 mm Hg and PPI ≥ 0.5 in hypertension with renal damage are significantly higher than those in simple hypertension and healthy people. PP and PPI can be served as the indexes of early renal damage, and it should be cautious on this kind of patients.
