To examine the effects of a 12-week tai chi program on quality of life and exercise capacity in patients with heart failure.
Thirty patients with chronic stable heart failure and left ventricular ejection fraction < or =40% (mean [+/- SD] age, 64 +/- 13 years; mean baseline ejection fraction, 23% +/- 7%; median New York Heart Association class, 2 [range, 1 to 4]) were randomly assigned to receive usual care (n = 15), which included pharmacologic therapy and dietary and exercise counseling, or 12 weeks of tai chi training (n = 15) in addition to usual care. Tai chi training consisted of a 1-hour class held twice weekly. Primary outcomes included quality of life and exercise capacity. Secondary outcomes included serum B-type natriuretic peptide and plasma catecholamine levels. For 3 control patients with missing data items at 12 weeks, previous values were carried forward.
At 12 weeks, patients in the tai chi group showed improved quality-of-life scores (mean between-group difference in change, -25 points, P = 0.001), increased distance walked in 6 minutes (135 meters, P = 0.001), and decreased serum B-type natriuretic peptide levels (-138 pg/mL, P = 0.03) compared with patients in the control group. A trend towards improvement was seen in peak oxygen uptake. No differences were detected in catecholamine levels.
Tai chi may be a beneficial adjunctive treatment that enhances quality of life and functional capacity in patients with chronic heart failure who are already receiving standard medical therapy.

    • "Meanwhile, Yeh et al. (2004)[36] in a study on the effect of tai chi on patients with Congestive Heart Failure (CHF), obtained a significant difference in QOL. Chan et al. (2004)[37] studying the effect of tai chi sport program on COPD patients showed that there was a significant difference in the study group (pursed-lip breathing and diaphragmatic breathing technique breathing sports) compared to control in the domains of symptoms signs and QOL activity, but there was no significant difference in the domains of the effects of disease and total score of QOL.

    ABSTRACT: Today, despite remarkable advances in the care of hemodialysis patients, the quality of life (QOL) for these patients is still unsatisfactory. Although previous reports confirmed the effect of exercise on the well-being of renal patients, less than 50% of end-stage kidney patients participate in a regular sports program. Tai chi is a slow and gentle exercise that is suitable for people with chronic illnesses and those with severe intolerance of exercise. Therefore, this study aimed to determine the effect of tai chi exercise on the QOL of hemodialysis patients. This was a quasi-experimental study conducted in a single group and in two steps. Twenty-five hemodialysis patients, admitted to hospitals in Isfahan, Iran, were selected, and their QOL was compared before and after intervention in two domains of satisfaction and importance. Convenience sampling was used. The sampling was convenience. The subjects were trained in the intervention through a single session of tai chi exercise class for one hour weekly, for 12 weeks, with a training compact disc (CD) that helped the patients to exercise at least twice a week at home. Data were collected by the completion of a demographic characteristics form and a researcher-made QOL questionnaire adopted from Ferrans and Powers Quality of Life Index Dialysis Version and the Kidney Disease Quality of Life-Short Form (KDQOL-SF) questionnaire by the researchers. The data were analyzed by a paired t-test through SPSS software version 18. Data analysis showed that there was a statistically significant difference in health and functioning (P < 0.001), socioeconomic (P < 0.001), and psychospiritual (P < 0.001) dimensions, and the family dimension had P = 0.002 in the satisfaction domain and P = 0.008 in the importance domain; the total score of quality of life in both domains was P < 0.001. According to the research findings, tai chi exercise improves the QOL score significantly in all dimensions, and adding tai chi classes to the rehabilitation program of hemodialysis patients can have a positive effect including an improved QOL for them. Therefore, this study supports the results of other research studies that showed positive effects of tai chi on QOL.

    • "The use of mind-body training has received increasing interest as a complementary intervention method among psychologists and medical professionals due to its documented therapeutic effects on many psychological problems, such as anxiety [1], insomnia [2], and depression [3]. Mind-body training has also been shown to have positive effects as a complementary treatment for many physical disorders, including irritable bowel syndrome [4], chronic pain [5], and cardiovascular problems [6]. Using the mind to affect physical and mental health is a core concept of traditional Chinese medicine. "

    ABSTRACT: Our previous studies have reported the therapeutic effects of 10-session Chinese Chan-based Dejian mind-body interventions (DMBI) in reducing the intake of antidepressants, improving depressive symptoms, and enhancing the attentional abilities of patients with depression. This study aims to explore the possible neuroelectrophysiological mechanisms underlying the previously reported treatment effects of DMBI in comparison with those of cognitive behavioral therapy (CBT). Seventy-five age-, gender-, and education-matched participants with depression were randomly assigned to receive either CBT or DMBI or placed on a waitlist. Eyes-closed resting EEG data were obtained individually before and after 10 weeks. After intervention, the DMBI group demonstrated significantly enhanced frontal alpha asymmetry (an index of positive mood) and intra- and interhemispheric theta coherence in frontoposterior and posterior brain regions (an index of attention). In contrast, neither the CBT nor the waitlist group showed significant changes in EEG activity patterns. Furthermore, the asymmetry and coherence indices of the DMBI group were correlated with self-reported depression severity levels and performance on an attention test, respectively. The present findings provide support for the effects of a Chinese Chan-based mind-body intervention in fostering human brain states that can facilitate positive mood and an attentive mind.

BNP is produced by ventricular cardiomyocytes and correlates with left ventricular dysfunction. "

    ABSTRACT: Exercise training is the cornerstone of rehabilitation for patients with cardiovascular disease (CVD). Although high-intensity exercise has significant cardiovascular benefits, light-to-moderate intensity aerobic exercise also offers health benefits. With lower-intensity workouts, patients may be able to exercise for longer periods of time and increase the acceptance of exercise, particularly in unfit and elderly patients. Tai Chi Chuan (Tai Chi) is a traditional Chinese mind-body exercise. The exercise intensity of Tai Chi is light to moderate, depending on its training style, posture, and duration. Previous research has shown that Tai Chi enhances aerobic capacity, muscular strength, balance, and psychological well-being. Additionally, Tai Chi training has significant benefits for common cardiovascular risk factors, such as hypertension, diabetes mellitus, dyslipidemia, poor exercise capacity, endothelial dysfunction, and depression. Tai Chi is safe and effective in patients with acute myocardial infarction (AMI), coronary artery bypass grafting (CABG) surgery, congestive heart failure (HF), and stroke. In conclusion, Tai Chi has significant benefits to patients with cardiovascular disease, and it may be prescribed as an alternative exercise program for selected patients with CVD.
