A major randomised trial published in the New England Journal of Medicine suggests a less invasive method of assessing blocked heart arteries performs just as well as the current standard approach — news that could eventually affect how cardiac patients across Kent are diagnosed and treated.

A Simpler Test for a Serious Problem
For anyone who’s sat in a cardiology waiting room at a place like the William Harvey Hospital in Ashford or Maidstone and Tunbridge Wells NHS Trust, the idea of a less invasive heart test will mean something real. Coronary artery disease — where the arteries supplying the heart become narrowed — affects hundreds of thousands of people across the UK, and working out exactly how serious a blockage is has traditionally required threading a pressure wire directly into the artery. It’s effective, but it’s not without risk or discomfort.
That’s why the results of the ALL-RISE trial, published in the New England Journal of Medicine, are drawing attention from cardiologists.
What the Trial Actually Found
The trial tested a technique called FFRangio — which stands for fractional flow reserve derived from angiography. In plain English, it uses the X-ray images already taken during a standard coronary angiogram to calculate blood flow restriction, rather than requiring a separate pressure wire to be physically inserted into the artery.
For their part, the results showed FFRangio was non-inferior to the pressure-wire guided approach. Non-inferiority is a specific term used in clinical research — it means the new method was not meaningfully worse than the existing standard when it came to reducing risk in patients with intermediate coronary stenosis. Intermediate stenosis refers to blockages that aren’t clearly severe enough to treat immediately but aren’t clearly safe to leave alone either. These are the tricky, in-between cases where getting the assessment right really matters.
It’s a meaningful finding. Not a cure, not a revolution — but a carefully evidenced step forward.
Why This Kind of Research Matters
Pressure-wire assessment is already considered a reliable tool, so the bar for any alternative to clear is high. The fact that FFRangio met that bar in a randomised trial — the gold standard of medical research — gives clinicians something concrete to work with when weighing up how to assess their patients.
According to the New England Journal of Medicine, the full ALL-RISE trial results and an accompanying research summary have now been published. The journal, widely regarded as one of the most authoritative medical publications in the world, provides peer-reviewed research that informs clinical practice across the NHS and beyond.
What Comes Next
Research published in a journal doesn’t automatically change what happens in your local hospital. New techniques go through review by bodies like the National Institute for Health and Care Excellence (NICE) before they’re routinely adopted across NHS trusts. But trial results like these feed directly into that process.
For cardiac teams across Kent — and the patients they look after — that pipeline matters.

Key Takeaways
- The ALL-RISE trial found that FFRangio, a technique using existing angiogram images to assess blood flow, was non-inferior to pressure-wire guided assessment in patients with intermediate coronary artery blockages
- Non-inferiority in this context means the newer, less invasive approach did not perform meaningfully worse than the current standard method at reducing patient risk
- The full trial results have been published in the New England Journal of Medicine, a leading peer-reviewed medical journal whose findings inform NHS clinical practice

What This Means for Kent Residents
If you or a family member has been referred for a coronary angiogram — perhaps through cardiac services at the William Harvey in Ashford, Darent Valley in Dartford, or Medway Maritime Hospital in Gillingham — this research is relevant background, though it won’t change your immediate care pathway overnight. Decisions about which assessment technique is used will remain with your clinical team, based on your individual circumstances and current NHS guidelines. If you have questions about a heart condition or a planned procedure, the best first step is always to speak with your GP or call NHS 111, who can advise on next steps and help you understand your options. In an emergency, always call 999.
