Mindful Movement Intervention for Post-MI Patients — HeartChi  

Myocardial Infarction Clinical Trial

Official title: Developing a Mindfulness Movement Intervention Program for Post-MI Patients: A Randomized 75-subject Pilot Clinical Trial of Tai Chi Versus Health Education in Post-myocardial Infarction Patients

Status Enrolling by invitation

Clinical Trial Summary

This study evaluates the feasibility and acceptability of a 12-week Tai Chi intervention for patients who have recently had a heart attack and are not participating in a standard cardiac rehabilitation program. Half of the 75 patients will be randomly assigned to the Tai Chi condition and the other half will be assigned to 12 weeks of Health Education. In addition to examining feasibility and acceptability, the investigators will evaluate the impact of participation in the Tai Chi condition on measures of cardiac health, physical function, self-reported health behaviors, and mental health as compared to Health Education within the context of this developmental/exploratory study.

Clinical Trial Description

Each year around 785,000 Americans endure a first heart attack and more than half will have another in the future. The American Heart Association (AHA) recommends exercise-based cardiac rehabilitation (CR) to aid prevention of future heart attacks. Despite the benefits of CR, only a small proportion of eligible patients participate in CR. Patients with other illnesses, women, older adults, and ethnic minorities are least likely to utilize CR services. Many medical centers do not have CR programs and patients have to travel to distant locations to undergo CR. In turn, Tai Chi has been studied in the elderly, requires no expensive equipment, can be practiced at home, and is well tolerated across fitness levels and co-occurring illnesses. Tai Chi serves as an aerobic exercise of low to moderate intensity. However, no Tai Chi studies in post-MI patients have employed state-of-the-art measures of cardiac function and exercise capacity and therefore it is unclear whether Tai Chi has similar benefits as CR during the period of recovery from a heart attack. This study is innovative in that it specifically targets patients who have not opted to participate in a formal CR program within 6 months of a first-time heart attack and emphasizes recruitment of patients spanning an older age range, physical function ability, women and minorities. A total of 75 men and women with a first time heart attack will be randomly assigned to 24 sessions of Tai Chi training composed of 8 meditative movements or to an equivalent "dose" of Health Education classes. Clinical assessments will be performed over a 4-5 month period, with testing occurring before, mid-way, after treatment, and at an 8-week follow-up. Our goal is to gather preliminary data on study feasibility, acceptability and to find indications of improvements in measures of cardiac health, physical function, health behaviors, and mental health. If the aims are met from this exploratory/development study, a future large scale study will be undertaken to confirm Tai Chi's effectiveness in post-heart attack patients. Such research is critically needed to aid the development of effective rehabilitative interventions that will be acceptable to a wider range of patients. ;
