Effects of community-based meditative Tai Chi programme on improving quality of life, physical and mental health in chronic heart-failure participants

Background: There is increasing evidence that coronary heart disease is linked with a number of psychosocial risk factors and biophysiological risk factors such as metabolic syndrome. This study aimed to compare Tai Chi programme heart-failure participants between the pre-intervention phase and six month after intervention time in health-related quality of life (HRQoL), including physical health, role-physical, bodily pain, general health, vitality, social functioning, role-emotional and mental health. In addition, the difference between pre-intervention and post-intervention time in psychological distress and resilience, body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were compared.Methods: A prospective intervention study was conducted in 2012 to evaluate the effectiveness of a community-based meditation Tai Chi intervention programme to improve heart-failure patients' health. Measures included the Short-Form 12 Health Survey (SF-12), General Health Questionnaire (GHQ30), resilience scale, BMI, blood pressure and waist circumference. Univariate analysis of variance was used to compare the difference between pre- and post-intervention in Tai Chi participants.Results: Outcomes differed in significance and magnitude across four HRQoL measures, psychological distress and resilience between the pre- and post-intervention time in heart-failure patients who participated in the Tai Chi exercise. The participants in the post-intervention time also reduced BMI, SBP, and waist circumference.Conclusions: Regular and more than six months Tai Chi exercises had a beneficial effect to HRQoL, reducing psychological distress, promoting resilience, and reducing the BMI and blood pressure level in heart-failure patients.
