Can getting a heart transplant change your personality?

You might think that in this day and age, we would be past seeing the heart–an organ that pumps blood–as a center of a person’s personality. However, the authors of this study regularly dealt with real patients who worried that their personalities would change after a heart transplant. In fact, they report that some patients refuse hearts from the opposite sex, and others experience anxiety about their sense of self after having a heart transplant.  To get a better handle on this phenomenon, the researchers surveyed heart transplant recipients to find out whether they thought their personalities changed after the surgery. The short answer? No. (Except for three people, who reported a distinct change in personality that they did not attribute to the life-changing experience of getting a new heart.) But our favorite response is from this patient: “’I love to put on earphones and play loud music, something I never did before. A different car, a good stereo-those are my dreams now. And I have thoughts now that I never had before.’ (remark: patient: 45 year old man, donor 17 year old boy).”

Does changing the heart mean changing personality? A retrospective inquiry on 47 heart transplant patients.

“Heart transplantation is not simply a question of replacing an organ that no longer functions. The heart is often seen as source of love, emotions, and focus of personality traits. To gain insight into the problem of whether transplant patients themselves feel a change in personality after having received a donor heart, 47 patients who were transplanted over a period of 2 years in Vienna, Austria, were asked for an interview. Three groups of patients could be identified: 79% stated that their personality had not changed at all postoperatively. In this group, patients showed massive defense and denial reactions, mainly by rapidly changing the subject or making the question ridiculous. Fifteen per cent stated that their personality had indeed changed, but not because of the donor organ, but due to the life-threatening event. Six per cent (three patients) reported a distinct change of personality due to their new hearts. These incorporation fantasies forced them to change feelings and reactions and accept those of the donor. Verbatim statements of these heart transplant recipients show that there seem to be severe problems regarding graft incorporation, which are based on the age-old idea of the heart as a centre that houses feelings and forms the personality.”

    This is crap. This is as valid as asking a group of people “Are you mentally ill?” with no professional diagnosis.

  • Nic Bishop

    What about the 40 odd thousand neurons in the heart? Can they not possibly share some of the characteristics that make up what we “feel” in our brain? I would say it is at least plausible worthy of being tested, not just from a survey

    • Karl Rouse

      The problem with this theory is that during the surgery all nerves to the heart are severed with no attempt at reconnection as it’s not needed for the heart to function. In light of this, how would any latent emotions even find their way to the brain?

      • 00Paul00

        The heart can communicate to the rest of the body through a magnetic field.

      • GDB

        Chemically! The heart supplies more chemicals to the brai n than vice versa.

      • Sarah

        Not completely true. I’ve been told by many doctors that reinnervation is possible.

  • Ben Gazi

    If you got a New heart from a guy with a wife or hot girlfriend she probable would bang you just to listen to your heart.

      How insightful…

    • Karl Rouse

      Dream on, Ben…

    I seem to recall a study showing that people with high blood pressure who were started on medications became less politically conservative. Not as a new personality from someone else, but simply the effects of lower blood pressure making people… calmer.

    Perhaps if this study holds up it has a similar cause. Not a lingering personality from the donor, but a healthy organ making people feel and act younger no matter who the donor was.

    • professor mister awesome

      The study’s assumptions are backwards, assuming that the agitated emotions are caused by the high blood pressure when the opposite is true: the high blood pressure is caused by constantly being agitated, angry, and high-strung.

      • Hitch Flatfoot

        Perhaps it’s both. Phychology had the concept of the mind body connection. What happens to one affects the other, and vice versa. And provided it was described correctly the study might not have been wrong. Given medication for blood pressure, blood pressure lowered (the goal) but also political leaning seemed affected. this is an interesting if very odd side affect

  • Roger

    This sounds kind of like a placebo effect. If people expect the new heart to affect their emotions and personality, then they self-report that it did.

    • Sola Balisane

      This seems like the most plausible explanation, and reading back over the article, the report from the 57-year-old man sounds like his concept of what a 17-year-old might want, not what modern teenagers actually want.

      • professor mister awesome

        Right. Teenagers today are more into dabbing and rainbow parties.

    • Sam Rinne Hooker

      Placebo effect is more than you think. 30% effect just from the placebo, like 50% from actual medicine. This means the added effect from medicine is actually less substantial than the placebo itself.

    Heart transplant has absolutely nothing to do with your personality. This organ is just an organ like any other inside of you that serves a purpose. For the heart, its just a pumping machine for the circulation of your blood. Thats all. Heart has nothing to do with your intuition or feelings, which ever one you want to call it.

    • 00Paul00

      Neurocardiology would infer something different of course.

    • justme444

      You are right about the heart, in fact, the whole body is nothing but a tent for the soul, which is your conscienceness

  • Karl Rouse

    Being a 28 year heart transplant survivor I can say that what really changes is a person’s perspective on life. We literally go from death’s door to weak but healthy and in doing so, we tend to have a keener appreciation for what being alive means and what life is about.

      I’m watching a soap opera & the guy had a transplant & is now having dreams of the donors life. Does that happen to you or is this just on tv? Lol, I know this is crazy but I do wonder if it’s true.

  • Mike Diedrich

    i have had two heart transplant one in 2010 that only lasted a year, this surgery was hard on me i am a male 58 yrs old in 2015, the first was from a women (in her 20 s) car crash,that is all i know about her,my wife said she seen a change in my personality and i noticed it also within that yr. and i wont say what change, the second transplant 12/2011 very lucky to get a chance at another heart and that don’t happen very often the doctors believe that it didn’t work the first time they are very reluctant to waste another heart with so many people waiting for one, but i revived another chance 12/2011,it went well and i am going on 4 yrs old this 12/2015, ( she was younger i will not mention the cause for respect to her, i am not the same as i was i can tell and the people around me,i do things i have never done in my life my personality has changed for the worst, i dont understand how any one can comment on this subject with out living through it your self or a close family member,there i guess you would have to be there

    • Picturewell

      Hi Mike, I’d be interested in finding out more about your story, as I’m involved in a doc about cellular memory. If you are interested in striking up a conversation about it please contact picturewell@ymail com

      Yours sincerely,

      Brian McGleenon

    • David Chacon

      I believe I can assist your understanding on this whole matter. I feel your frustration and anxiety. I’m
      confident I can resolve it to a large degree.

  • Sam Rinne Hooker

    They’re asking us to believe 6% over the 94% that said that it’s crap. I believe it could, but they’ve made a weak case for it.

    • Zach

      Or they are scared to mention a new split personality they now live with…

    ” As a man thinketh in his heart, so is he. ”

      but he thinks with his brain controlled by his soul.

  • Randy Hall

    Whoever wrote this apparently dropped out of middle school.

  • Sonal Surekas

    I love my mom,dad,my bro, and my husband ,if i donate my heart to somebody then is it possible that my all feeling will also be transfer…???

  • l cm

    you can argue yes or no….but the TRUTH is nobody knows what is possible or how to legitimately prove it.
