BBC science correspondent Pallab Ghosh has the age of his heart assessed by artificial intelligence.
How much has my lack of exercise and less than perfect diet affected my heart age?A new artificial-intelligence tool reveals by how much drinking, smoking, poor diet and a lack of exercise prematurely ages an individual's heart.
"Some people have hearts that are much younger - and others have ones that have aged prematurely and they are more prone to diseases. So we want to find out what those factors are".I told Prof O'Regan I had not led the unhealthiest of lifestyles but, like many people, could improve my diet, lose a little weight and exercise more.
The AI analysis, however, showed up the knocks and scrapes accumulated over a lifetime, through drinking, smoking, poor diet and a lack of exercise, Prof O'Regan told me.The earliest signs of premature ageing can be so subtle even expert cardiologists are unable to detect them - but the AI tool can, because it has also been fed the images of 40,000 people of varying heart health along with their health outcomes.
He told me that was exactly what he wanted to find out in the next part of his research, which has been published in the journal Nature Communications. Another set of genes, associated with the immune system, also played a part. Immune cells fight diseases and clean up dead tissue - but if they become overactive, they can scrub too hard and cause inflammation, damaging the tissue.
