Chinese Journal of cardiovascular Rehabilitation Medicine 2012;21(6):571-574
Objective: To observe influence of aerobic exercise on blood pressure in patients with white coat hypertension (WCH). Methods: A total of 51 newly diagnostic WCH patients were randomly divided into exercise group (n=26) and WCH control group (n=25). Patients in exercise group received aerobic exercise training (walking on flat ground by constant speed, twice a day, 50~80 min each time for three months); The WCH control group did not exercise. Office blood pressure (OBP) and 24h ambulatory blood pressure monitoring (ABPM) were measured in both groups before and three months after treatment. Results: There were no significant difference in indexes of OBP and ABPM between two groups before treatment (P>0.05). After three months, compared with before treatment, indexes of OBP and ABPM significantly decreased in exercise group and they were significantly lower than those of WCH control group in OBP [OSBP: (132.54±17.60) mmHg vs. (143.68±20.35) mmHg, ODBP: (89.12±18.39) mmHg vs. (92.75±17.24) mmHg] and ABPM [ mSBP:(121.57±20.86) mmHg vs. (128.06±19.45) mmHg, mDBP:(76.24±15.28) mmHg vs. (84.55±17.31) mmHg; dSBP:(124.27±22.50) mmHg vs. (130.85±24.61) mmHg, dDBP:(77.95±18.42) mmHg vs. (82.36±17.59) mmHg], P<0.05~0.01. Conclusions: Aerobic exercise can significantly improve blood pressure in patients with white coat hypertension.
