Abstract
Objectives: The importance of domestic blood pressure values and 24 hour ambulatory blood pressure monitoring (24hABPM) has been discussed in the context of risk factors of cerebrovascular diseases. In this study, we evaluated the effect of stroke lesions for the alteration of circadian blood pressure (BP) pattern.Methods: Acute intracerebral hemorrhagic patients were enrolled in this study (n=32, 62.0± 11.1 y). 24hABPM was performed on admission and at 3weeks following. Circadian BP pattern was classified into dipper and non-dipper types based on the ratio of the average daytime and nighttime BP. Difficulty of BP control at the acute phase was classified into fair and poor groups.Results: There was no significant correlation between the hematoma size and BP at the emergency room. However, the average hematoma size was significantly larger in the poor BP control group compared with the fair control group. Patients, in whom dipper type was observed either on admission or at 3weeks, exhibited significantly smaller hematoma compared with patients in whom non-dipper type was observed.Conclusion: The larger hematoma may affect the BP control in the acute phase and relate to the non-dipper type of the circadian BP pattern.
