Reconditioning : When ?
The best : initialised before Transplantation….. ( heart failure )
• Phase I :
– With respect to recovery ( Anémia; complications…)
Personnalisation +++
• Phase II:
– As soon as possible !....
Rejections ?
1 month post Graft ( 1 )
– Always :
5 years post Graft ; fonctionel improvment : 35% ( 2 )
A reduced training response contributes to a poorer prognosis. (4)
• Phase III :
– Effectivness and security ( 3)
– Same physiological involution than non H.Tx. ( 12 years )… ( 4)
Physical activity patterns
and
Exercise Performance in
H.Tx.
«H.Tx. Recipients still achieve only 50% to 70% of normal values for
exercise capacity. »
« Among the factors suggested to explain the reduced exercise
tolerance in CTx recipients is deconditioning. »
Myers J.
J Cardiopulm Rehabil. 2003 Mar-Apr;23(2):100-6
What for limitations ?...
•
•
•
•
•
•
•
•
•
cardiac denervation,
Systolic / diastolic dysfunction,
Pulmonary diffusing capacity impairment
endothelial dysfunction
Peripheral chemoreceptor sensitivity
peripheral limitations
abnormal muscle structure and function
pharmacological side effects
physical deconditioning...
Capacités Fonctionnelles: Quelles limites ?
• Vasodilatation périphérique limitée ?
Endothèline : x 5
(1)
Capacités de dilatation
(2)
• Capacités d’extraction périphérique d’ O2 limitée ?
• Myopathie ?
(3)
Post I.C. + Immunothérapie ?
Densité capillaire
Fibres type I
Enzymes mitochondriales..... mais la restauration de corrige pas tout
(4)
(5)
• Fonction ventriculaire gauche ?
Fraction de raccourcissement
Relaxation
(6)
• Fonction ventriculaire droite ?
(7)
Régénération myocardique: une chimère ? (8)
Ne pas oublier les effets ostéoarticulaires et musculo tendineux des corticoïdes…
H.Tx. : Myocardial Reinnervation ?
• No parasympathetic reinnervation
• Possible sympathetic reinnervation (anteroseptal wall);
Correlation with:
Time after transplantation ; nonrejecting patients
Recipient Age at the time of H.Tx;
Donor Age
• Higher H.R. max. during Exercise ( p < 0.01 )
• Improvment of contractile Fonction of L.V.( p < 0.01 )
Bengel F. M. 2001
« The evidence for sympathetic reinnervation is reviewed, with the conclusion that
while it may occur over time, it is inconsistent, and partial in nature. »

on cardiac reserve in transplanted hearts.

Physical Activities Post Rehabilitation
• Leisure - time physical Activities :
– Endurance Training ( intensity < 85 % VO2 max. )
– Gymnastic
– Strenght training ( < 50 % M.V.C. )
• Competitive Sports :
– After Cardiac screening
– Importance of performing regular physical exercise
to maintain the highest level of aerobic fitness
World Transplant Games Federation
« Programs for recipients through involvement of the W.T.G. »
Games Objectives:
•
•
•
•
•
To encourage rehabilitation through sport
To demonstrate quality of life after organ transplantation
To promote organ donor awareness
To recognise doners and donor families
To celebtrate life
www.wtgf.org
Sports after TRANSPLANTATION
• Europeen Transplant Games
• World Transplant Games
… since 25 Years !
• 2005 :
Cardiac screening introduced for > 40 years
… No adverse events
...
But orthopedic injuries

World Transplant Games :
Conclusion *
• W.T. Games activities are safe
• Sporting activities for recipeients of all ages presents
benefits which far exceed the risks
• Safe W.T. Games require a fierce commitment to
protocols of risk management
• On demonstrating the safety of the W.T. Games (500
events), it is now possible to reassure recipients and
their medical teams and carers.

Eligibility Recommendations for
Competitive Athletes With H.T. ?
• Recognizing that there may be exceptional circumstances where an
athlete will require an otherwise prohibited substance for medical
purposes,
• Formal therapeutic exemption mechanisms are available with prior
consideration and approval A.U.T.

Conclusions
« Regular physical exercise has a major potential to improve Tx. outcomes
and should therefore be incorporated in routine standard Tx. Management »
Patients limits:
78 % are sedentary;
Most frequently identified barriers in newly transplanted recipients:
« Too sick » : 40%
Lack of motivation : 40 %
Bad weather : 32 %
Medical Care limits:
15 % did not discuss exercise;
39 % did not prescribe a specific amount
