Q. Can somebody's personality change after heart bypass surgery?

Yes, they can. Studies show that major cardiac surgery such as a heart bypass can have a significant impact on someone's psychological and emotional well-being. When you go through something so challenging, it can often result in changes to our personality or the way we view ourselves and the world around us.
In one study published in Psychology Today, researchers explored how individuals’ personalities shifted after undergoing bypass surgery for coronary artery disease (CAD). After interviewing 30 patients who had undergone coronary artery bypass grafting (CABG), researchers saw that “patients exhibited greater acceptance of their limitations and less fear of uncertainty following CABG compared to before it." They also noted "increased assertiveness", "positive affect" and a stronger sense of purpose in life.
These positive changes may be due to an increased appreciation for life after such an experience - when faced with mortality, many people start looking at things differently afterwards. In addition to this shift in perspective may come fewer risks associated with behaviour due to reduced impulsivity or cognitive biases leading to more structured decision making processes which may lead to further positive change over time.
Of course, not everyone experiences these profound shifts - different individuals respond differently based on their own perceptions and coping strategies used prior to and post-surgery - but most studies point towards positive changes observed by those who underwent heart bypass surgery as well as improved quality of life overall afterwards compared with before their operation took place.
