| Two NHS hospital trusts in London are using AI technology to see if they can spot type 2 diabetes in patients up to a decade in advance of the condition occuring. | Two NHS hospital trusts in London are using AI technology to see if they can spot type 2 diabetes in patients up to a decade in advance of the condition occuring. |
| Imperial College and Chelsea and Westminster hospital NHS foundation trusts have started training the AI system - called Aire-DM - that checks patients' ECG heart traces for subtle early warning signs that are tricky for doctors to otherwise detect. | Imperial College and Chelsea and Westminster hospital NHS foundation trusts have started training the AI system - called Aire-DM - that checks patients' ECG heart traces for subtle early warning signs that are tricky for doctors to otherwise detect. |

| Early work, external suggests the system can spot risk about 70% of the time. | |
| Giving the AI extra details about other background risk factors, such as the patient's age, sex and whether they already have high blood pressure and or are overweight, can improve the predictive power, says lead researcher Dr Fu Siong Ng. | |
| He told BBC News: "It is already quite good just with the ECG data, but it is even better when you add in those." | He told BBC News: "It is already quite good just with the ECG data, but it is even better when you add in those." |
| An ECG (electrocardiogram) records and can reveal problems with the electrical activity of the heart, including the rate and rhythm. | An ECG (electrocardiogram) records and can reveal problems with the electrical activity of the heart, including the rate and rhythm. |

| As part of the trial up to 1,000 patients at both hospitals will have ECG scans read by the AI system to see if it helps detect and predict disease. | As part of the trial up to 1,000 patients at both hospitals will have ECG scans read by the AI system to see if it helps detect and predict disease. |
| It's not something that will be offered to routinely yet, although the experts hope it could be rolled out more widely on the NHS. That could take five years or more, says Dr Fu. | It's not something that will be offered to routinely yet, although the experts hope it could be rolled out more widely on the NHS.

| Professor Bryan Williams, Chief Scientific and Medical Officer at the British Heart Foundation, said: "This exciting research uses powerful artificial intelligence to analyse ECGs, revealing how AI can spot things that cannot usually be observed in routinely collected health data. This kind of insight could be a gamechanger in predicting future risk of developing type 2 diabetes, years before the condition begins. | Professor Bryan Williams, Chief Scientific and Medical Officer at the British Heart Foundation, said: "This exciting research uses powerful artificial intelligence to analyse ECGs, revealing how AI can spot things that cannot usually be observed in routinely collected health data.

| "Type 2 diabetes is a rapidly growing health challenge that increases the risk of developing heart disease, however with the right support it is possible for people to reduce their risk of developing the condition. We look forward to seeing how this technology could be incorporated into clinical practice." | "Type 2 diabetes is a rapidly growing health challenge that increases the risk of developing heart disease, however with the right support it is possible for people to reduce their risk of developing the condition.
