摘　　要：目的观察老年高血压病患者昼夜血压节律对左房容积(LAV)和左室容积(LVV)的影响。方法根据夜间血压下降百分率将126例老年高血压病患者分为年龄、性别匹配的两组,夜间血压下降率﹤10%为非杓型组(A组),≥10%为杓型组(B组)。受试者给予24h动态血压监测结合超声心动图检查,观察并比较2组患者的血压昼夜节律及左房容积和左室容积的改变。结果 (1)A组24h收缩压均值和舒张压均值、白天收缩压均值和舒张压均值、夜间收缩压均值和舒张压均值水平高于B组(均P﹤0.05)。(2)A组的左室收缩末期容积(ESV)、左室舒张末期容积(EDV)较B组增大(均P﹤0.05),但LAV、左心房容积指数(LAVI)两组间差异无统计学意义(均P﹥0.05)。结论非杓型血压节律的老年高血压患者较杓型血压节律者更易导致左心室容积增大。OBJECTIVE To investigate the influence of circadian rhythm on left atrial volume(LAV)and left ventricular volume(LVV)in elderly essential hypertension(EH)patients.METHODS 126 patients with essential hypertension were divided into 2 groups according to their decreasing rate in night﹤10% into non-dipper(A group),≥10% into dipper(B group),which were matched in age and gender.Ambulatory blood pressure monitoring and echocardiography were performed in all of them.RESULTS(1)24h SBP,dSBP,nSBP and nDBP were significantly higher in non-dipper group than those in dipper group(P﹤0.05).(2)The EDV and ESV of A group were increased than B group(P﹤0.05).The difference of LAV and LAVI of the two groups was no statistically significant(P﹥0.05).CONCLUSION Non-dipper circadian rhythm could induce the increase of LVV in elderly patients with essential hypertension.
