摘要
目的:观察高血压病患者血压晨峰(morning blood pressure surge,MBPS)与心脏肥大和颈动脉内膜-中膜厚度(IMT)的关系。方法:高血压病患者386例。根据动态血压检测结果,分为晨峰组(146例)和非晨峰组(240例),全部病例同步记录24 h动态血压和动态心电图,观察指标为24 h动态血压参数;超声技术检测左室质量指数(LVMI)、左房内径(LAD)、颈动脉IMT等指标。结果:晨峰组与非晨峰组比较:LVMI分别为(119±21)g/m2和(92±12)g/m2(P<0.01);LAD分别为(46±11)mm与(38±10)mm(P<0.05);颈动脉IMT分别为(1.36±0.24)mm与(0.92±0.18)mm(P<0.01);左室肥厚(LVH)的检出率分别为67%与30%(P<0.01)。结论:与无血压晨峰的高血压病患者比,具有血压晨峰的高血压病患者LVH和颈动脉硬化更显著,心血管重构更显著,左心房内径更大。
AIM: To evaluate the association between morning blood pressure surge(MBPS) and cardiovascular remodeling in hypertensive patients.METHODS: A cohort of 386 patients with hypertension under 24 h ambulatory blood pressure monitoring were categorized as MBPS group(n=146) and non-MBPS group(n=240).Left ventricular mass index(LVMI) and thickness(IMT) of carotid artery were measured by ultrasonography in all patients and left ventricular hypertrophy(LVH),left atrial dimension(LAD) and intima-media thickness were compared between groups.RESULTS: Compared with those in the non-MBPS group,LVMI [(119±21) g/m2 vs.(92±12) g/m2,P〈0.01],LAD [(46±11) mm vs.(38±10) mm,P〈0.05],IMT of carotid artery [(1.36±0.24) mm vs.(0.92±0.18) mm,P〈0.05] and LVH(67% vs.30%,P〈0.01) were significantly higher in the MBPS group.CONCLUSION: Hypertensive patients with MBPS have more severe LVH and carotid atherosclerosis and larger LAD compared with those of hypertensive patients without MBPS.MBPS is associated with more significant cardiovascular remodeling.
