Psychosocial and physical rehabilitation after heart transplantation: 1-year follow-up

Experience on the rehabilitaion of 62 heart-transplanted patients with a mean follow-up period of 15 months and a total survival rate of 79% is reported. From the present study we may conclude that: (a) One month after surgery, oxygen consumption of transplanted patients compared to coronary artery bypass-grafted patients was statistically lower (p<0.025). An excess ventilation was observed in transplanted patients in relation mainly to an excessive increase in blood lactates. (b) Improvement of maximal working capacity observed immediately after grafting was still enhanced after 1 year of a comprehensive rehabilitation program (p<0.001). This improvement was more related with an improvement of the respiratory function and of the peripheral factors than with a circulatory effect. (c) Four months after transplantation 71% of the patients still at work 6 months before operation returned to work. (d) The quality of life, well-being and heart acceptation demonstrated an immediate increase in physical items after transplantation while psychosocial items decreased postoperatively and normalized after weeks or months.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Exercise and heart transplantation. A review

Results of heart transplantation as therapy for end-stage cardiac diseases are encouraging not only because of actuarial survival curves but also because of the recovered quality of life for the heart transplant recipient. Although heart transplantation drastically improves the physical capacity of the patients, heart recipients still have a reduced maximal aerobic capacity compared to healthy people. Altered resting and exercise haemodynamics, due to cardiac denervation, are a common finding after orthotopic heart transplantation: increases in heart rate and stroke volume at exercise are first linked with the augmented venous return and later with the increased plasmatic noradrenaline level. Maximal heart rate and stroke volume are both reduced when compared to innervated heart. Reduced cardiac output response to exercise therefore results in early anaerobic metabolism, acidosis, hyperventilation and diminished physical capacity. In spite of an altered ventilatory adaptation to exercise, characterised by hyperpnoea in most transplant patients, ventilation is not the limiting factor for exercise in heart recipients without associated obstructive pulmonary disease. Endurance training restores lean tissue, decreases submaximal minute ventilation, increases peak work output, maximal ventilation and peak heart rate. Guidelines for prescribing exercise are not yet standardised dueto the limited number of studies on a sufficient cohort of heart recipients. Nevertheless, recommendations similar to those used for persons with coronary heart disease, with modifications due to the denervated heart, seem to be used. The cardiocirculatory and pulmonary capacity of heart transplant recipients allow them to undertake endurance sports activities such as walking, jogging, cycling and swimming, and these should be encouraged.SCOPUS: re.jinfo:eu-repo/semantics/publishe
