充血性心力衰竭患者24h血压监测结果分析

Analysis of 24 hour blood pressure in patients with congestive heart failure

为了探讨充血性心力衰竭（ＣＨＦ）对２４ｈ血压的影响，我们分析了４１例ＣＨＦ患者２４ｈ血压，并与５１例心功能正常的患者做对比研究。结果显示所有病人的血压均呈昼高夜低的杓形变化，心衰组昼夜血压差（昼夜收缩压差＋昼夜舒张压差）显著小于对照组（Ｐ＜０．０１），其２４ｈ平均收缩压和舒张压以及白天和夜间的平均收缩压和舒张压亦明显低于对照组（Ｐ＜０．０１）。结果提示ＣＨＦ患者２４ｈ血压幅度和昼夜血压波动均小于心功能正常的患者。

hour blood pressure (BP) at rest was recorded with bedside monitors in 41 patients with congestive heart failure(CHF) and 51 patients with normal heart function(NHF) The observed parameters included the drop of BP at night (dnBP), the mean 24 hour systolic and diastolic BP (24h SBP,24h DBP), and the mean daytime and nighttime BP(dSBP,dDBP,nSBP,nDBP) The results showed that the daytime BP was higher than the nighttime BP(′dipper′ type BP) in all the patients; the dnBP was significantly less in CHF patients than in NHF patients(P<0 01),the 24h SBP,24h DBP,dSBP , dDBP,nSBP and nDBP were all significantly lower in CHF patients than in NHF subjects(P<0 01￣0 001) Our findings indicate that the 24 hour BP correlated with the heart function, and the magnitude of 24 hour BP and its change between day and night in patients with CHF were less than in NHF subjects
