Holistic MedicineChinese philosophical tradition
contains a strong preventive element linked to balance: between humankind and nature, and between mind and body (Zhou, 1983).
A sound mind in a sound body is essential to longevity

Origins of Tai Chi
• Around 500 A.D. Indian Buddhist monk Bodhidarma developed Shaolin boxing to strengthen the monks at the monastery in Honan who were weakened by long hours of meditation and physical neglect
• Martial skills were also needed to protect the monks who sometimes came under attack in the remote mountains

End of the Sung Dynasty (960-1278 A.D.) Chang San-feng applied the concepts of Yin-Yang, proper breathing, and Taoist philosophy to Shaolin boxing.
Of the five animals; tiger, dragon, leopard, snake, and crane, the movements of the snake and crane are most able to overcome strong and unyielding opponents. Flexibility and suppleness in place of strength.

Roll Back
The practice of Tai Chi teaches us that by yielding we can overcome forceful attacks.

Low impact, mindfully meditative movements with integrated breathing techniques that generate an aerobic work-out
The level of intensity is adjustable by using larger or smaller movements.
Many tai chi interventions, have been examined specifically for elderly and frail individuals
Characteristics of Tai Chi

Tai chi serves as an aerobic exercise of moderate intensity
in older adults
• HR generally increases by 55% to 70% of maximum when adjusted to age
• Increased oxygen consumption and lactate accumulation in older adults

Tai chi Benefits in Older Adults
• 30% higher VO2 peak and work rate – bicycle ergometry
• Reduced blood pressure, cholesterol and age-related decline of venous compliance
• Reduced SNS activity: acute pre-ejection fraction (estimate of SNS-driven myocardial contractility time)
• Increased apparent parasympathetic activity

Tai Chi and Quality of Life Older adults -
– Increases emotional well-being and self-efficacy– More vigorous and less tension, depression,
anger and fatigue– Improved functional status: such as walking,
posture control capacity and reductions in falls

What is HF? A progressive condition: heart muscle
becomes weaker and gradually loses the ability to pump enough blood. Blood, water, and other fluids build up in tissues, veins, and organs, causing congestion and damage.

Somatic symptoms of depression such as fatigue and sleep disturbances are common in HF patients
May lead to physical inactivity and a spiraling decline in physical and cardiac function (Whooley et al, 2007).

Inflammation and Exercise
• Aerobic exercise training in C AD patients- reduction in inflammatory factors – C RP, IL-1 , IL-6, INF levels, and increase in IL-
1 0 (Goldhammer, 2005)
• Regular exercise induces anti-inflammatory effects – elevated levels of anti-inflammatory cytokines
and suppression of TNF-α production (Petersen and Pedersen, 2006)

Although HF produces debilitating symptoms and loss of quality of
life, until recently there have been few behavioral
interventions

Medicare states: “the evidence on the benefits for congestive heart failure is not sufficient for coverage expansion for cardiac rehabilitation for these patients.”

Standard Exercise and HF
Historically HF patients were counseled to limit physical activities.
Whereas recent studies have shown moderate exercise can be performed safely in properly evaluated NYHA II-III HF patients (McKelvie et al, 2008).

HF-ACTION (N = 2331) (O’Connor et al, 2009):
• Possibly reduced morbidity and mortality– Exercise studies in HF have been conducted
on relatively young patients (e.g. average age of 59 in HF-ACTION) with little comorbidity.
• Also, for home-exercise walking less than half of HF patients are eligible for the study (Jolly et al, 2007).

Determine if tai chi vs usual care reduces symptoms of depression
and fatigue in HF patients?
Determine if there are concomitant alterations in pro-inflammatory
cytokines

Methods
• 40 HF patients (37-81 years; mean age=58.8, SD=4.2) – tai chi (n = 15), standard exercise (n = 10), usual
care (n = 15)• Beck Depression Inventory (BDI): sub scales
Cognitive/affective and Somatic/affective • Fatigue (MFSI)• Intracellular expression of cytokines measured
pre- and post- intervention

HF Patients with BDI >10• Reduced BDI scores of an average of 30%
in tai chi group. – Thirty-eight percent (38%) of tai chi
participants and none of the controls improved by at least one SD.
• Control subjects had an average increase in BDI scores of 25% – further evidence that subclinical depression
should be treated because of a greater risk of developing MDD at one year

Somatic Symptoms of Depression and Tai Chi
• Somatic symptoms of depression in HF– Friedman Test: rank order of 21 BDI items
for baseline BDI scores; fatigue, and effort required to perform work = top two items ranked
• 33% of tai chi and none of control subjects improved by at least one SD in BDI somatic symptom scores

Tai Chi Affects on Fatigue and Depression
∆ MFSI physical fatigue (beta = .510, p = .027) and ∆ MFSI mental fatigue (beta = .588, p = .019)

– Tai chi may improve quality of life by improving somatic symptoms of depression.

Tai Chi, Standard Exercise, Usual Care and IL-10
• Tai chi training is associated with an increase in anti-inflammatory cytokine stimulation.
• Increases in IL-10 with exercise including tai chi may reduce pro-inflammatiory activity and lead to reduced HF disease progression.

Summary• Tai chi training was assoc with reduced
depression symptoms.– Of clinical interest for HF pts > 10 BDI
• Somatic symptoms, particularly fatigue appear to be a major component of depression symptoms in HF patients
• Tai Chi reduced somatic symptoms of depression and fatigue measures
• Tai chi and exercise were assoc with increased anti-inflammatory cytokine IL-10

Limitations• Too small a sample size to differentiate
tai chi from standard exercise for depression symptoms.
• No attention control condition.
• No measure used to determine distinguishing characteristics between tai chi and standard exercise.– E.g. Mindfulness questionnaires

Future Directions
• Echocardiogram, and other standard measures used in HF trials
• Longer follow-up• Look at larger cohort of older adults with
HF• Delineate differences between standard
exercise and tai chi
