A University of Pittsburgh research team led by Dr. Kang Kim has received a $2.8 million NIH grant to develop super-resolution intravascular ultrasound (IVUS) technology that can visualize the tiny vessels surrounding arteries, called the vasa vasorum. These vessels play a key role in the development of vulnerable plaques that can lead to heart attacks. By combining advanced ultrasound sensors, microbubble contrast agents, and novel signal processing, the team aims to detect plaque vulnerability earlier and more accurately—potentially transforming how cardiovascular disease is diagnosed and prevented.

Nick Nurmohamed and colleagues have raised critical concerns regarding the detection of risk factors and the use of preventive measures before the occurrence of myocardial infarctions (MI). They performed a retrospective cohort study examining U.S. patients with their first MI between 2017 and 2022. Their results are published in European Heart Journal.

Around 1 in 6 older adults take aspirin as their primary method of preventing cardiovascular disease – despite stricter guidelines that no longer always call for it, a study finds. Almost one-quarter of those aspirin users started taking the medication without a physician recommendation.

New cutting-edge software developed in Melbourne can help uncover how the most common heart tumour in children forms and changes. And the technology has the potential to further our understanding of other childhood diseases, according to a new study.
