(Press-News.org) Vienna, Austria – 12 December 2025: Increased volume of epicardial adipose tissue, detected by cardiovascular imaging, was found to be associated with greater myocardial injury after a myocardial infarction.1 These findings were presented today at EACVI 2025, the flagship congress of the European Association of Cardiovascular Imaging (EACVI), a branch of the European Society of Cardiology (ESC).
Cardiovascular diseases are the leading cause of death globally, accounting for around one-third of all deaths, of which 85% are due to myocardial infarction (MI) and stroke.2 “Mortality after an MI is largely driven by the extent of injury to the myocardium, the heart muscle. Characterising risk factors driving myocardial injury severity may help to identify patients are at the highest risk,” noted study presenter, Ms Clara Hagedorn from the University Hospital Göttingen, Germany.
Epicardial adipose tissue (EAT) is the layer of fat between the myocardium and the lining of the heart, directly surrounding the coronary arteries. Under certain pathological conditions, EAT releases inflammatory mediators leading to myocardial infiltration and constrictive effects. Over time, adverse remodelling of the myocardium can occur.3 It is already known that EAT is associated with coronary artery disease and major cardiovascular events.3 “As a potential marker, we investigated the relationship between the volume of EAT and the extent of myocardial injury after an MI using cardiovascular magnetic resonance (CMR) imaging,” explained Ms Hagedorn.
A prospective multicentre study enrolled 1,168 patients who underwent CMR within 10 days after a percutaneous coronary intervention following an acute MI. The study population was divided into quartiles based on EAT volume.
The researchers found that patients with EAT volume in the upper quartile were older than those in the lower quartile (66 years versus 63 years; p=0.002) and had a higher body mass index (28.9 kg/m2 versus 27.4 kg/m2; p=0.001). Higher EAT volume was independently associated with greater infarct size (p=0.032) and larger areas at risk (p=0.018), but lower microvascular obstruction (p=0.012). There appeared to be no differences in left ventricular ejection fraction, the heart’s pumping ability, between patients with larger versus smaller EAT volume.
Summing up the findings, Ms Hagedorn said: “We were able to show that patients with increased EAT volume exhibited greater acute myocardial injury following MI. Non-invasive quantification of EAT volume using CMR could play a decisive role in cardiovascular risk assessment beyond conventional risk factors and prospective validation is now warranted.”
Senior author, Doctor Alexander Schulz, also from the University Hospital Göttingen, Germany, concluded: “We would like to understand more about the mechanisms by which EAT impacts the myocardium. MI occurs at a relatively late stage in the development of coronary artery disease and it may be possible to intervene earlier in the process, identifying patients with elevated EAT volume and modulating effects as a preventive measure.”

Jeonbuk National University researcher proposes a proposing a two-stage decision-making framework of lithium governance in Latin America
2025-12-12
The evolving global order, intense geopolitical competition, and anxiety over supply chain vulnerabilities in this century have led to urgent concerns over supply chain resilience as well as national security. Amidst these upheavals, governments across the globe are making substantial efforts to reaffirm control over strategic sectors, especially in the field of critical minerals. Notably, lithium has become strategically highly important owing to its use in lithium–ion batteries for technologies aimed at decarbonization, including electric vehicles (EVs) and renewable energy storage systems. The demand for lithium in EV production ...
Chromatin accessibility maps reveal how stem cells drive myelodysplastic progression
2025-12-12
Over the past few decades, advances in hematology have illuminated how a delicate balance between stem cell self-renewal and differentiation sustains healthy blood formation. In myelodysplastic syndrome (MDS), however, this balance collapses, leading to abnormal blood cell development and a heightened risk of progression to acute myeloid leukemia. Despite major progress in genetics, the molecular events that trigger this transformation within stem cells have remained unclear.
To address this, a research team led by Professor Atsushi Iwama and Senior Assistant Professor Motohiko Oshima from the Division of Stem Cell and Molecular Medicine, Center for Stem Cell Biology and Regenerative Medicine, ...
Cartilaginous cells regulate growth and blood vessel formation in bones
2025-12-12
Normal, regulated growth of skeletal bones is a crucial part of the growth of mammals. This is a complex process involving the growth of cartilaginous cells or chondrocytes, their transformation into bone-building cells or osteoblasts, and the formation of new blood vessels to supply the newly formed bone tissue.
While osteoblasts evolve from a variety of progenitor cells, over 60% of osteoblasts in mammals originate from one class called hypertrophic chondrocytes (HCs). HCs are versatile cells involved in a variety of bone growth and maintenance tasks, ...

Swedish freshwater bacteria give new insights into bacterial evolution
2025-12-12
Bacteria are among the most diverse and ancient forms of life on Earth. Yet, much of what we know about them comes from a small group of species, mostly studied for their roles in human health.
“The vast majority of bacterial species remain unexplored, and this really limits our understanding of how bacteria shape ecosystems and have evolved to thrive in different environments,” says Joel Hallgren, lead author of the study.
Most bacteria reproduce through simple, symmetrical cell division. However, members of one ...
Global measures consistently underestimate food insecurity; one in five who suffer from hunger may go uncounted
2025-12-12
URBANA, Ill. — International humanitarian aid organizations rely on analyses from the Integrated Food Security Phase Classification (IPC) system, a global partnership that monitors and classifies the severity of food insecurity to help target assistance where and when it is most needed. Those analyses are multifaceted and complex – often taking place in regions where data is scarce and conditions are deteriorating – and stakeholders tend to assume they overestimate need. However, a new study from the University of Illinois Urbana-Champaign and collaborators, published in Nature Food, finds the opposite is the case: global food insecurity analyses systematically ...

Sea reptile’s tooth shows that mosasaurs could live in freshwater
2025-12-12
Mosasaurs, giant marine reptiles that existed more than 66 million years ago, lived not only in the sea but also in rivers. This is shown by new research based on analyses of a mosasaur tooth found in North Dakota and believed to belong to an animal that could reach a length of 11 metres. The study, conducted by an international team of researchers led from Uppsala University, shows that mosasaurs adapted to riverine environments in the final million years before they became extinct.
In 2022, palaeontologists found a large tooth from a mosasaur in North Dakota. It was ...
Pure bred: New stem cell medium only has canine components
2025-12-12
Canine induced pluripotent stem (iPS) cells possess the ability to differentiate into any type of cell, making them a useful tool for investigating common canine diseases and disease states, including those of humans.
When culturing iPS cells, a culture substrate is required to serve as a scaffold for the cells, which adhere to it and proliferate. Without the scaffold, the cells die or fail to differentiate.
Currently, recombinant proteins derived primarily from humans are used as culture substrates for canine iPS cells. However, these human-derived ...
