非勺型原发性高血压患者的升主动脉直径分析

目的探讨非勺型原发性高血压患者的升主动脉直径变化。方法选取勺型高血压患者50例（勺型高血压组），非勺型高血压患者50例（非勺型高血压组）及健康体检者（对照组）50例。所有受捡者行常规化验检查、24h动态血压监测、心脏超声测量升主动脉内径。对各组升主动脉内径进行比较，观察非勺型高血压患者对升主动脉内径的影响。结果与勺型高血压病组及健康对照组比较，非勺性高血压病组的升主动脉直径明显升高，差异有统计学意义（P〈0．05）。结论非勺型高血压患者主动脉直径显著高于勺型高血压病或健康者。

Objective To study the difference of thoracic aortic diameter in non dipper hypertensive patients. Methods 150 subjects were included in the study, 50 were of non dipper hypertension group, same number of dipper hypertension group and healthy control group. History collection and routine laboratory tests, a 24-hour ambulatory blood pressure monitoring, cardiac ultrasound measurement of thoracic aortic diameter were for all the subjects. Compared the aortic diameter of the various groups, primarily to analyze the effect of non dipper hypertension on aortic diameter. Results When compared non dipper hypertension group with dipper hypertension group and healthy control group, aortic diameter increased significantly as 33.68 ± 1.97 VS 28.44 ± 1.69 ; 33.68 ± 1.97 VS 28.34 ± 1.67, P〈0.05. Conclusion Aortic diameter of non dipper hypertension group markedly increase compared with the dipper hypertension group or healthy control group.
