      On the issue of heart transplants, is it possible that the recipient can inherit certain characteristics of the donor?
      Please help.

      It depends what you mean by characteristics.

      If we think of it in terms of cardiovascular fitness then yes, the recipient would ‘inherit’ the donor’s cardiac ability, to some degree. It doesn’t mean they could leap out of the hospital bed and run a 10k though!

      I would imagine that if the heart of a fitter person was donated to a less fit person, the recipient would gain a greater proportion of cardiac muscle, lower resting heart rate, greater stroke volume and consequently, greater cardiac output. These factors would become less and less prevalent if/when reversibility occurs, however.

      That being said, they would have to replace the recipient’s heart with a donor organ of similar size, so perhaps hypertrophy is somewhat irrelevant.
