Characteristics analysis of ambulatory blood pressure of patients with type 2 Dm and combined high blood pressure

Objective To investigate the characteristics of ambulatory blood pressure (ABP) of patients with type 2 Dm and combined high blood pressure. Methods 120 cases were divided into 4 groups according to having or not having diabetes and hypertension. ABP of 30 testees in each group were monitored for 24h. Results Mean systolic blood pressure (BP) and systolic BP load were higher in hypertensive diabetes group than that of primary hypertensive group without diabetes, while 24 h diastolic BP and diastolic load were little lower in the former group. The BP difference between day and night of patients in diabetes group, whether they having hypertension or not, was less than that of patients without diabetes in another 2 groups. Conclusion Patients in diabetes group lose the normal ambulatory BP rule in which BP is higher at daytime and lower at night, and this abnormal phenomenon occurs even when patients have no hypertension. Suggestions: hypertension pathology of patients with diabetes is probably somewhat different from non-diabetes. BP of patients with diabetes should be monitored periodically, and some preventive measures should be taken before hypertension according to abnormal situations.
