Study of high blood pressure telling
Chinese researchers have noted in a study that patients with hypertension should pay more attention to fluctuations in their blood pressure during daily treatments and management, in addition to controlling average blood pressure overall.
The study, recently published in the International Journal of Cardiology, was led by Prof Yu Jinming at the school of public health at Shanghai-based Fudan University.
Yu and his team observed and analyzed a large-sized data sample, trying to find out the relation between blood pressure variability and cerebral stroke. Blood pressure variability refers to the degree of fluctuation of blood pressure within a certain period of time. The research showed that the long-term follow up on blood pressure variability is of great significance in predicting an occurrence of cerebral stroke.
Lowering blood pressure variability has become the new target in the treatment and management of hypertension. In the past, studies on the relation between blood pressure variability and cerebral stoke mainly focused on short term monitoring. Since the monitors were limited and observation windows short, the results failed to reflect the actual fluctuation condition of blood pressure and its impact on cerebral stroke.
In order to solve this problem, Yu and his team carried out the study based on the community residents’ health archives data. A total of 122,636 adult patients with hypertension were selected for the study.
Research found that a total of 4,522 hypertension patients suffered cerebral stroke during the follow-up period from 2005 to 2011. The fluctuations among this group were significantly higher than among the patients who did not suffer cerebral stroke.
