[Effects of Tai Chi exercise on blood pressure, hemorheology and long-term quality of life in elderly hypertensive patients]

OBJECTIVE: To investigate the effect of Tai Chi exercise on blood pressure, hemorheology and long-term quality of life in elderly hypertensive patients. METHODS: From May 2015 to October 2016 in Suihua First Hospital, 70 elderly hypertensive patients were divided into exercise group and control group according to random number table method, 35 cases in each group. Both groups were given routine treatment, and the exercise group performed Tai Chi exercise on this basis, and the ambulatory blood pressure and hemorheology indicators were compared between the two groups, followed up for 1 year, and the complications and quality of life were compared between the two groups. RESULTS: After 6 months, the 24-hour ambulatory blood pressure of the two groups decreased significantly, and the 24-hour ambulatory blood pressure of the exercise group was lower than that of the control group (P<0.05). After 6 months, the levels of various hemorheology indexes in the control group had no significant changes (P>0.05), and the whole blood viscosity (ηb, low-cut 10 s-1, high-cut 120 s-1), plasma viscosity of the exercise group (ηp, 10 s-1), erythrocyte sedimentation rate (ESR), hematocrit (HCT), erythrocyte aggregation index (RAI), whole blood reduced viscosity (ηre, low cut 10 s-1, high cut 120 s-1 ) were significantly lower than those before the study, and the above indicators in the exercise group were significantly lower than those in the control group (P<0.05). After 6 months, the erythrocyte deformation index (EDI) of the exercise group was significantly higher than that before the study, and the exercise group was significantly higher than that of the control group (P<0.05). The incidences of heart failure, renal impairment and cerebral hemorrhage in the exercise group were significantly lower than those in the control group (P<0.05). The physical function, social function, social function, physical pain, emotional function, mental health and vitality scores of the exercise group were significantly higher than those before the study (P<0.05), and the quality of life scores of the exercise group were significantly higher after 1 year of follow-up. in the control group (P<0.05). CONCLUSION: Tai Chi exercise can significantly reduce blood pressure, improve blood rheology indexes, reduce complications and improve quality of life in elderly hypertensive patients.
