Artificial intelligence can predict when patients with a heart disorder will die, according to scientists.
The software learned to analyze blood tests and scans of beating hearts to spot signs that the organ was about to fail. The team, from the UK's Medical Research Council, said the technology could save lives by finding patients that need more aggressive treatment. The results were published in the Journal of Radiology.
According to the researchers, high blood pressure in the lungs damages part of the heart, and about a third of patients die within five years after being diagnosed. There are treatments: drugs, injections straight into the blood vessels, a lung transplant. But doctors need to have an idea of how long patients might have left, in order to pick the right treatment.
The software was given scans of 256 patients' hearts, and blood test results. When this data was combined with eight years of patient health records, the artificial intelligence predicted when patients would die.
The software could look about five years into the future. It correctly predicted those who would still be alive after one year about 80% of the time. The figure for doctors is 60%.
The team now want to test the software works in other patients in different hospitals before assessing whether it should be made widely available to doctors. The researchers also want to use the technology in other forms of heart failure, such as cardiomyopathy, to see who might need a pacemaker or other forms of treatment.
Dr Mike Knapton, from the British Heart Foundation, said, "This exciting use of computer software in medical practice will help doctors in the future to make sure that patients are receiving the correct treatment before the condition deteriorates and leaves them needing a lung transplant. The next step is to test this technology in more hospitals with heart disease."
Which tablet computer should YOU be buying: They are this year's must have ... and there's a style to suit everyone.
Best for young children LeapPad Explorer 2, £68
Pros: The education games are well- designed, the built-in video camera is a fun way to play at being a film director. Cons: Some of the games are shockingly expensive. And the power adaptor is not included. | Best for teenagers iPad 4th generation, £399-£659
Pros: No other tablet can compete with the near one million ‘apps' (the name Apple created for specially-designed downloadable programs) available for the iPad. Simple to use, even for those who usually struggle with technology. Cons: Considerably more expensive than most competitors. |
Best for working parents Microsoft Surface, £399-£559
Pros: The Surface is good for watching movies — a bonus when stuck in the airport on a business trip — and surfing the internet. Cons: The keyboard is an expensive add-on — costing up to £109. It might be cheaper to buy a laptop (though a tablet is much smaller and lighter). | Best for bookworms Amazon Kindle Paperwhite, £109 Nearly all tablets let you download books. It's a great way to take a mountainous pile of hardbacks on holiday without stuffing your suitcase. But most tablets have a shiny screen — which can be very distracting (分心) when you're trying to read. The Paperwhite is different: its matt screen and crisp black lettering imitate the look of words on paper brilliantly. And yet you can still read the words in the dark. Pros: Easy on the eye, excellent battery life, 180,000 free books (if you subscribe to the Amazon Prime customer loyalty service) plus hundreds of thousands more to buy. Cons: No TV, films, games, internet or camera. |
