Implantable cardiac monitors detect atrial fibrillation after stroke of unknown cause recommended for routine NHS adoption

Doctors can check on their patients remotely using Reveal LINQ monitor.
Hundreds of strokes could be prevented with a new implantable monitor that transmits data to doctors remotely, following draft NICE guidance published today.
The Reveal LINQ monitor - developed by Medtronic - identifies more people who have atrial fibrillation after a stroke with no identified cause or transient ischaemic attack (TIA). Those patients can then begin treatment for their atrial fibrillation to reduce the risk of another stroke.
It is the first device of its type to be recommended for NHS use by NICE.
Meindert Boysen, director of the NICE Centre for Health Technology Evaluation, yesterday said:
“This is an innovative monitor which has the potential to reduce the number of strokes suffered by those with atrial fibrillation.
“It may mean fewer hospital visits for those with atrial fibrillation; reduce the need for rehabilitation and mean patients are reassured that AF will be detected in a timely manner so treatment can begin.
“This device can provide a level of reassurance to those who live in fear of having another stroke and we believe Reveal LINQ is likely to be a cost-effective use of NHS resources.”
Minister for Innovation Nicola Blackwood yesterday said:
“It is fantastic to see innovative technology being adopted to vastly improve the lives of those with conditions that can be extremely debilitating, particularly patients at risk of having multiple strokes.
“We are constantly striving to improve patient experience, and we will continue to do so as we invest record amounts of money into the NHS and ensure we are utilising advancements in healthcare as much as possible.”
One-third of the size of a AAA battery, it is implanted under the skin in the chest usually under local anaesthetic, to track a heart’s activity over long periods of time, transmitting data back to the patient’s doctor via a mobile phone network.
Undiagnosed atrial fibrillation is believed to be responsible for a significant portion of the 30,000 strokes with an unidentified cause, also known as cryptogenic strokes, that occur each year in the United Kingdom.
Cryptogenic stroke patients have a high risk of recurrent stroke and require a confirmed atrial fibrillation diagnoses to receive therapy to prevent a repeat stroke.
Data presented to the NICE diagnostics advisory committee showed atrial fibrillation after a cryptogenic stroke was detected in five times more people using a Reveal monitor for six months compared with people who didn’t have the device implanted.
Clinical experts highlighted that it is important that non-invasive ECG monitoring is carried out first before Reveal LINQ is considered.
The cost of the Reveal LINQ is £1,800 plus the cost of implanting the device. It was assumed in the assessment that people with an implantable cardiac monitor would have one face-to-face follow up a month after the procedure and then would be remotely monitored.
NICE diagnostic guidance is non mandatory, but it is considered best practice for the NHS to implement it.
A consultation on the draft recommendations is now underway at nice.org.uk until 4 February 2020.
