动态血压变异性与原发性高血压病患者左心室肥厚的关系

目的探讨动态血压变异性与原发性高血压病患者左心室肥厚的关系。方法采用心电图和超声心动图检查，将100例原发性高血压病患者根据有无左心室肥厚分为肥厚组与无肥厚组。同时选择50例血压正常患者为对照组进行24h动态血压监测。结果高血压左心室肥厚组与正常对照组或无肥厚组24h各时间段血压均值及血压变异性比较差异有统计学意义（P〈0．01），无肥厚组与正常对照组比较，血压均值差异有统计学意义（P〈0．01），血压变异性除白昼收缩压差异有统计学意义外，其余差异无统计学意义（P〈0．05）。结论动态血压变异性与高血压左心室肥厚关系密切，后者对前者有促进作用，前者对后者的风险性预测有一定价值。

Relationship between ambulatory blood pressure variability and left ventricular hypertrohy in patients with essential hypertension

Objective To investigate the relationship between ambulatory blood pressure variancebility （BPV） and left ventrielar hypertrophy （LVH） in patients with essential hypertension. Methods Using the electrocardiogram and the echocardiogram inspection, 100 essential hypertension patients were divided into two groups by whether he or she was LVH, and 50 patients whose blood pressure were normal were selected as the control group. Results The ambulatory blood pressure monitoring of 24 hours （ABPM） showed that blood pressure means in three groups were significant different（ P 〈 0.01 ）. The means between control group and the hypertension group with no LVH were obvions different （ P 〈 0.01） ,the means of systolic blood pressure （SBP） was different （ P 〈 0.01 ）. Conclusions The relationship between BPV and LVH is obvious, the latter（LVH） could promote the former（BPV）,and the former（BPV） could predict the latter （LVH）.
