Abstract ObjectiveTo explore the relevance of circadian rhythm of blood pressure and exercise 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 pressure, hypertensives were divided into two groups: normal (dipper) (n=182) and abnormal (nondipper) (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 Nondipper 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 pressure group. ConclusionHypertensives with abnormal circadian rhythm of blood pressure showed abnormal ambulatory blood pressure and higher parameter values of ambulatory blood pressure.
