目的探讨妊娠高血压综合征动态血压监测的特征变化。方法用动态血压仪测定３２例妊娠高血压患者的血压，并和２０例正常妊娠和２０例正常相当年龄的健康妇女作对照。结果正常孕妇ＡＢＰＭ各参数均高于同龄健康妇女；妊娠高血压ＡＢＰＭ各参数均高于正常孕妇。妊娠高血压蛋白尿阳性者的昼夜血压比值及血压负荷数均较无蛋白尿者明显增高，且与病情严重度相关。结论正常中、晚期妊娠的收缩压有增高趋势，舒张压升高对妊娠高血压更具特征性。ＡＢＰＭ测定所出现的血压昼夜节律变化和血压负荷增高和病情的严重度相关。
Objective To investigate the characteristics of ambulatory blood pressure monitoring in pregnancy-induced hypertension. Methods The blood pressure of 32 hypertensive patients with gestational hypertension was measured with an ambulatory blood pressure monitor and compared with 20 normal pregnant women and 20 normal healthy women of the same age. Results The parameters of ABPM in normal pregnant women were all higher than those in healthy women of the same age. The parameters of ABPM in hypertensive pregnancy were all higher than those in normal pregnant women. The ratio of diurnal blood pressure and blood pressure load of patients with gestational hypertension proteinuria were significantly higher than those without proteinuria and correlated with the severity of the disease. Conclusions Systolic blood pressure in normal and late pregnancy tends to increase, and elevated diastolic pressure is more characteristic of gestational hypertension. The changes in circadian rhythm of blood pressure seen in the ABPM assay correlated with increased blood pressure load and the severity of the disease.
