心脏康复(CR)计划降低了有急性冠状动脉事件或血管重建术病史的患者的总体死亡率和心血管死亡率，但只有30%的患者参加了心脏康复计划，流失率高达60%。太极是一种基于轻度/中度有氧运动并辅以冥想成分的身心练习，对于没有参加CR的患者来说，太极可能是一种可能的锻炼选择。60名患者将被随机分成两组(每周两次太极拳训练，持续12周)或“加分”训练(每周三次太极拳训练，持续12周，然后每周1-2次，持续12周)。测量将在注册后的基线、3个月、6个月和9个月进行。主要结果是确定每种剂量的可行性、可接受性和安全性。次要结果包括对每个剂量对加速计评估的体力活动的影响大小的估计；符合当前推荐体力活动的患者的比例；以及健康、生活质量、体重和睡眠的测量。此外，我们将收集有关可能的中介因素的探索性信息(锻炼自我效能、感受到的社会支持、韧性、正念和抑郁)。这项试点研究的结果将为没有参加传统CR计划的患者提供太极作为一种锻炼选择的有效性的初步迹象。研究结果还将阐明太极练习可能改善动脉粥样硬化性冠心病患者整体体力活动的可能机制。
Cardiac rehabilitation (CR) programs reduce overall and cardiovascular mortality in patients with a history of acute coronary events or revascularization procedures, but only 30 % of patients enroll in CR and attrition rates reach up to 60 %. Tai chi, a mind-body practice based on light/moderate aerobic exercise accompanied by meditative components could be a possible exercise option for patients who do not attend CR. Sixty patients will be randomized to a “LITE ” condition (one tai chi session twice weekly for 12 weeks) or to a “PLUS” condition (one tai chi session 3 times weekly for 12 weeks, followed by maintenance classes 1–2 times weekly for an additional 12 weeks). Measurements will be conducted at baseline, 3-, 6-, and 9 months after enrollment. The primary outcome is to determine the feasibility, acceptability and safety of each dose. Secondary outcomes include estimates of effect size of each dose on accelerometry-assessed physical activity; the proportion of patients meeting current recommendations for physical activity; and measures of fitness, quality of life, body weight, and sleep. In addition, we will collect exploratory information on possible mediators (exercise self-efficacy, perceived social support, resilience, mindfulness, and depression). Findings from this pilot study will provide preliminary indications about the usefulness of tai chi as an exercise option for patients not attending traditional CR programs. Results will also shed light on the possible mechanisms by which tai chi practice may improve overall physical activity among patients with atherosclerotic coronary heart disease.
