A SIMPLE test developed in the West of Scotland could predict if a patient will survive a heart attack.
The test can accurately work out the extent of vessel injury in the heart, and can predict if the patient is likely to go on to develop heart failure, or even die.
It was developed at the Golden Jubilee Hospital in Clydebank, which is Scotland's national heart and lung centre.
The test - known as the Index of Microvascular Resistance (IMR) - uses a pressure and temperature sensitive wire inserted into the coronary artery.
Early treatment following a heart attack can reduce the chance of heart failure and improve both wellbeing and chances of survival.
For those who survive a heart attack there is a risk that the heart will have been damaged, which can lead to heart failure.
The study was carried out in partnership with the University of Glasgow and the British Heart Foundation and will will be presented at the British Cardiovascular Society annual conference today.
Lead researcher Professor Colin Berry, a Cardiologist at the Golden Jubilee National Hospital, said: "After a suspected heart attack, a patient is routinely given a coronary angiogram to identify any narrowed blood vessels.
"Currently, we make treatment decisions based on this standard assessment technique but it can only identify narrowed vessels and cannot tell the doctor if, or how much, heart blood vessel damage has occurred.
"This new technique can tell us the level of damage in a matter of minutes, allowing us to quickly and accurately identify patients who are at a high risk of heart failure after their heart attack.
"The results of this study will help us improve the outlook for this group of patients and help us develop new treatments to limit heart damage, reducing the burden of heart failure on the patient, their families and carers."
Professor Jeremy Pearson, Associate Medical Director at the British Heart Foundation, said: "More and more people are surviving heart attacks due to the huge advances we've made in cardiology, but that isn't the end of the story.
"If we can identify the people at greatest risk of developing heart failure following a heart attack, and treat them more quickly, we could reduce the effects that these terrible events can have on individuals and communities."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers.
