【摘要】 目的探讨老年高血压患者脉压(PP)与左房构型改变的相关关系。方法对63例老年高血压患者进行血压测量,记录并计算收缩压(SBP)、舒张压(DBP)和脉压PP;用超声心动图技术对心脏各参数进行测量,包括左房内径(LAD),左房内径指数(LADI),左室重量指数(LVMI)等。将PP≥60mmHg的患者33例列为A组,PP<60mmHg患者30例列为B组。结果A组中LAD,LADI显著大于B组(P<0.01)。LADI与SBP,PP和LVMI呈密切正相关(r分别为0.58,0.52和0.51前者P<0.001,后2者P<0.01),与年龄、病程相关性相对较弱(r分别为0.38和0.31,P<0.05)。结论老年高血压患者PP与左房构型改变密切相关。更多还原

【Abstract】 Objective:To find out the relationship between pulse pressure(PP)and left atrial geometric pattern in aged patients with hypertension.Methods:63aged patients with hypertension were examined by blood pressure and echo cardiography,the different index of BP and left atrial dimension(LAD).Left atrial dimension index(LADI)and left ventricular mass index(LVMI)were measured.The patients were divided into group A(PP≥60mmHg),and group B(PP<60mmHg)according to PP.Results:The LAD and LADI were significantly higher in group A than group B(allP<0.01),significant correlation existed among the LADI and SBP,PP,LVMI,age,course(r=0.58,0.52,0.51,0.38and0.31).More close correlation was among the LADI and SBP,PP,LVMI(all P<0.01).Conclu-sions:There is close correlation between PP and LADI in aged patients with hypertension.更多还原
