This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Heart Failure (HF) is a major public health problem in the United States, affecting approximately 5 million adults. Despite recent advances in pharmacological therapy and technological devices, HF is the most common reason for hospitalization among Medicare patients and is reaching epidemic proportions as the population ages. New and inexpensive interventions that can improve functional capacity, quality of life, as well as affect disease progression, are needed. Tai Chi is a popular mind-body exercise form that is a potential therapeutic adjunct for heart disease. Tai Chi incorporates both gentle physical activity and meditation. It may be particularly suited to frail and de-conditioned patients with HF, but has never been rigorously studied in this population. We conducted a feasibility study of Tai Chi in patients with HF (n=30) and found that those randomized to a Tai Chi program significantly improved their exercise capacity (six-minute walk distance), quality-of-life (Minnesota Living with Heart Failure score), and neurohormonal status (serum B-type natriuretic peptide levels) compared to patients who did not participate in Tai Chi. As part of a funded NCCAM study, we are now conducting a randomized controlled trial (n=150) over three years that compares a 12-week Tai Chi program with usual conventional care (both groups receiving HF educational materials). Patients with chronic stable HF (systolic dysfunction, left ventricular ejection fraction ?40%, New York Heart Association Class I-IV) will be recruited from outpatient primary care and cardiology clinics. Our primary aim will be to examine Tai Chi's effects on functional capacity and quality-of-life. Secondary aims are designed to further elucidate the mechanism of Tai Chi's effects, including examination of cognitive-behavioral or psychosocial influences (e.g., mood, psychosocial functioning, self-efficacy, beliefs and expectations of mind-body medicine) and HF-specific physiologic/metabolic processes in response to meditative exercise (e.g., neurohormonal status, heart rate variability and markers of autonomic tone, myocardial structure and function). The results of our proposed research will help define the role of Tai Chi in current HF management, further our understanding of the mechanism of action, and provide preliminary analyses of the costs and benefit of treatment.

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中得到体现。列出的机构是中心的机构，不一定是研究者的机构。心力衰竭 (HF) 是美国的一个主要公共卫生问题，影响约 500 万成年人。尽管最近在药物治疗和技术设备方面取得了进展，心力衰竭仍然是医疗保险患者住院的最常见原因，并且随着人口老龄化，心力衰竭已达到流行的程度。需要新的、廉价的干预措施来提高功能能力、生活质量并影响疾病进展。太极拳是一种流行的身心锻炼形式，是心脏病的潜在治疗辅助手段。太极拳结合了温和的身体活动和冥想。它可能特别适合虚弱和身体状况不佳的心力衰竭患者，但从未在这一人群中进行过严格的研究。我们对心力衰竭患者 (n=30) 进行了太极拳的可行性研究，发现那些随机接受太极拳项目的患者显着提高了他们的运动能力（六分钟步行距离）和生活质量（明尼苏达州用心生活）与未参加太极拳的患者相比，失败评分）和神经激素状态（血清 B 型利钠肽水平）。作为 NCCAM 资助研究的一部分，我们现在正在进行一项为期三年的随机对照试验 (n=150)，将为期 12 周的太极拳计划与常规常规护理（两组均接受 HF 教育材料）进行比较。慢性稳定性心力衰竭（收缩功能障碍，左心室射血分数≥40%，纽约心脏协会 I-IV 级）患者将从门诊初级保健和心脏病诊所招募。我们的主要目标是研究太极拳对功能能力和生活质量的影响。次要目标旨在进一步阐明太极拳的作用机制，包括检查认知行为或心理社会影响（例如情绪、心理社会功能、自我效能、身心医学的信念和期望）以及太极拳特定的生理/对冥想运动的代谢过程（例如神经激素状态、心率变异性和自主神经张力标记、心肌结构和功能）。我们提出的研究结果将有助于明确太极拳在当前心力衰竭治疗中的作用，进一步了解其作用机制，并提供治疗成本和效益的初步分析。
