A study published in Circulation: Cardiovascular Imaging, examined over 1,000 people and found doctors should consider an individual’s activity level before diagnosing common heart conditions.
One of the effects of exercise is an enlarged heart, caused by the heart muscles becoming thicker as they become stronger.
Dr Declan O’Regan, of the MRC Clinical Sciences Centre, at Imperial College London, and one of the lead scientists on the research says “It’s well known that the hearts of endurance athletes adapt in response to exercise, a phenomenon called ‘athlete’s heart’. This study is the first to show that healthy adults who do regular exercise may also develop enlarged hearts. As a result, there’s a risk that some active adults could be misdiagnosed with heart disease”.
