Cardiac MRI Improves Detection of Lamin Heart Disease
Updated june 05, 2025
Cardiac magnetic resonance imaging (MRI) shows promise in detecting lamin heart disease, a potentially fatal genetic condition, according to a UCL-led study. The research suggests MRI scans can identify heart inflammation, scarring, and impaired function more effectively then standard tests, leading to better risk prediction for patients.
Lamin heart disease, caused by mutations in the LMNA gene, impacts the heart’s ability to pump blood and can trigger dangerous heart rhythms.While rare, affecting approximately one in 5,000 people, it is often undiagnosed. The study, featured in the JACC: Cardiovascular Imaging journal, highlights the potential of cardiac MRI in identifying subtle heart abnormalities in LMNA mutation carriers.
Researchers argue that incorporating MRI data into risk assessments could improve decisions regarding heart transplants or implantable defibrillators. Current risk estimates rely on electrocardiograms (ECGs), genetics, symptoms, and basic heart function measurements via echocardiograms.
Dr. Gaby Captur, senior author from UCL Institute of Cardiovascular Science, emphasized the limitations of relying solely on genetics for predicting disease progression. “Genetics alone cannot predict how this disease will progress,” captur said. “The current tool to predict risk is not brilliant and underperforms for women in particular.”
Dr. Cristian Topriceanu, lead author from UCL Institute of Cardiovascular Science, noted that cardiac MRI detects subtle signs of heart damage, inflammation, and impaired muscle function that other tests miss.This is especially critically important for identifying individuals who could benefit most from emerging gene therapies for lamin heart disease and improving arrhythmia treatment.
the study involved analyzing MRI data from 187 participants, including individuals with lamin heart disease, dilated cardiomyopathy, and healthy volunteers. Results indicated that heart damage, inflammation, and scarring were prominent features of lamin heart disease, distinguishing it from non-genetic dilated cardiomyopathy. Researchers also observed that participants with truncated LMNA genes exhibited worse heart functioning, providing insights into the mechanics of the heart.
What’s next
Larger studies are needed to confirm these findings,but the research suggests that cardiac MRI could become a standard tool in managing lamin heart disease,potentially improving risk predictions and treatment strategies for this cardiomyopathy.
