Heart Transplant patient and Sports JC Verdier Institut Cœur Effort Santé Paris 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. » Kavanagh T. 2005 • Influence of the beta1-Adrenoreceptor polymorphism on cardiac reserve in transplanted hearts.

J.A.C.C 1999 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 ...

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. * XXIII International Congress of the Transplantation Society, Vancouver, Canada 2010 « Extremes Cases » … • COMPETITION ? – Tennis : Competition in …..Australia Rajendran AJ. 2006 (1) – Athlétisme : 11 s au 100 m Carl Whittaker 22 s au 200 m • Saut à l’élastique ( Normandie Française ! ) • MONT BLANC, France – 5 H.Tx. ; 2003 ; Transforme. • 6.000 m Bolivie !
