Breakthrough heart MRI technique accurately predicts heart failure risk in general population

New research looking at more than 39,000 UK biobank participants found those with higher heart pressure estimated by Magnetic Resonance Imaging (MRI) were five times more likely to develop heart failure 

Key risk factors discovered for increased heart pressure include age over 70, high blood pressure, obesity, alcohol consumption and male gender 

Breakthrough by University of East Anglia and Queen Mary University of London suggests that heart MRI could potentially replace invasive diagnostic tests

MRI scans could replace invasive heart tests, as new research shows they can reliably estimate pressures inside the heart to predict if a patient will develop heart failure. 

The research from the University of East Anglia (UEA) and Queen Mary University of London also identified key risk factors for increased pressure inside the heart, which leads to heart failure. 

These risk factors include being over 70, having high blood pressure, being obese, alcohol consumption and being male. 

Co-lead author Dr Pankaj Garg, from UEA’s Norwich Medical School, said: “Heart failure is a lethal condition resulting from rising pressures. One of the most significant findings of this study is that MRI-derived pressure measurements can reliably predict if an individual will develop heart failure.   

“This breakthrough suggests that heart MRI could potentially replace invasive diagnostic tests. Participants with higher heart pressure measured by MRI had a fivefold increased risk of developing heart failure over six years.” 

Previous pioneering research involving UEA, and the universities of Sheffield and Leeds has shown that heart MRI techniques can estimate pressure in the heart and are linked to symptoms and signs of heart failure.  

However, to date it remained unknown if heart MRI derived pressures can predict heart failure risk in a general population.  

Analysing data from more than 39,000 UK Biobank participants, this latest research demonstrates that MRI-detected pressure changes can identify heart failure risk without invasive procedures.  

Co-lead author Dr Nay Aung, from the William Harvey Research Institute at Queen Mary University of London, said: “Additionally, we identified key risk factors for developing high heart pressure: age over 70, high blood pressure, obesity, alcohol consumption and male gender.  

“By combining these factors, we developed a model to predict individual heart failure risk. This advancement enables prevention, early detection and treatment of heart failure, which could save many lives.” 

A heart MRI is a type of scan that uses powerful magnets and radio waves to create detailed images of the heart. Unlike X-rays or CT scans, it does not use harmful radiation.  

In this research work, both teams analysed heart MRI data from 39,000 UK biobank participants using artificial intelligence techniques and estimated the pressure inside the heart. They then evaluated each individual’s risk factors and their chance of developing heart failure in the future over a six-year follow-up period. 

The research was co-led by the University of East Anglia in partnership with Queen Mary University of London. Other contributions were made by St Bartholomew’s Hospital in London, Norfolk and Norwich University Hospitals, the universities of Leeds and Sheffield, Health Data Research UK and the Alan Turing Institute. 

UK Biobank is a large-scale biomedical database and research resource containing de-identified genetic, lifestyle and health information and biological samples from half a million UK participants.

The work was supported by the National Institute for Health and Care Research (NIHR) and the Wellcome Trust.
