Tai Chi Beneficial to Heart-Failure Patients with Preserved Ejection Fraction
 
October 28, 2012 -
This is a study jointly conducted by several prestigious medical organizations in Boston area, including Harvard Medical School, Massachusetts General Hospital and Veterans Administration Boston Healthcare System.

Although exercise is an important component of heart failure management, optimal regimens, particularly in heart failure with preserved ejection fraction (HFPEF), are uncertain. Tai chi is a mind-body exercise that may have potential benefits but has not been studied in this population.

The authors randomized 16 patients with HFPEF to either 12-weeks Tai Chi or aerobic exercise. Assessments included peak oxygen uptake, 6-minute walk, quality of life, echocardiography, mood, and self-efficacy at baseline and at 12 weeks. Cardio-respiratory measures during exercise were obtained to characterize training intensities.

Overall, adherence was excellent (89% attendance). Change in peak oxygen uptake was similar between groups after 12 weeks, but 6-minute walk distance increased more after Tai Chi. While both groups had improved Minnesota Living With Heart Failure scores and self-efficacy, Profile of Mood States (POMS)-Depression scores improved more with Tai Chi. Cardio-respiratory assessment during Tai Chi showed lower oxygen uptake, respiratory rate, and heart rate.

The group of researchers concluded that Tai Chi is feasible and safe in HFPEF. Therepeutic endpoints appear similar with Tai Chi relative to aerobic exercise despite a lower aerobic training workload.

The study is published on Oct 12, 2012 by the journal Congestive Heart Failure.  .
