目的探讨原发性高血压患者血压昼夜节律变化与运动血压的相关性。方法检测287例原发性高血压患者的动态血压和运动血压，根据夜间血压下降率分为昼夜节律正常（杓型）组（n=182）和非正常（非杓型）组（n=105）。根据运动试验中最大运动量时血压过高反应及恢复期血压恢复缓慢分运动血压正常组（n=85）和非正常组（n=202）。各组间数据进行比对分析。结果非杓型组最大运动量时血压值均高于杓型组，运动血压异常组24h、白昼及夜间血压均值高于运动血压正常组。结论非杓型原发性高血压患者容易发生运动血压异常，运动血压异常者动态血压值参数增高。

英文摘要：

Objective To explore the relevance of circadian rhythm of blood pressure and exer- cise blood pressure in hypertensives. Methods The ambulatory blood pressure and exercise blood pressure of 287 hypertensives were examined. According to the decrease rate of night blood pres- sure, hypertensives were divided into two groups： normal （dipper） （n = 182） and abnormal （non- dipper） （n = 105 ） circadian rhythm of blood pressure; According to the blood pressure response to maximal exercise and the recovery rate of blood pressure recovery, hypertensives were divided into two groups ： normal （ n = 202 ） and abnormal ambulatory blood pressure （ n = 85 ）. All data between two groups were analysed. Results Non-dipper group hypertensives showed higher blood pressure levels than that of dipper group. Compared with the mean blood pressure of 24 h, day and night, abnormal ambulatory blood pressure group were higher than those of normal ambulatory blood pres- sure group. Conclusion Hypertensives with abnormal circadian rhythm of blood pressure showed abnormal ambulatory blood pressure and higher parameter values of ambulatory blood pressure.
