Article • Imaging modalities for quantifying myocardial blood flow

Nuclear cardiology – a nuclear perspective on matters of the heart

Nuclear cardiology is a specialised field in nuclear medicine that evaluates the heart function to help diagnosing conditions such as coronary artery disease and to assess treatment efficacy, whilst minimising invasive procedures like biopsies. More recently, clinicians have increasingly opted for nuclear imaging over endomyocardial biopsy to diagnose cardiac amyloidosis, allowing for earlier…

Sex differences in imaging cardiovascular disease

An interplanetary title for a quite down-to-earth topic: The symposium "Men are from Mars, women are from Venus" at the EACVI congress (European Association of Cardiovascular imaging) launched into the differences between the hearts of men and women. While the speakers could firmly establish that both sexes share the same home world, variations in their cardiac anatomy warrant a more…

Study identifies 15 new biomarkers for pre­-dementia

A study by an international research group identified 15 novel biomarkers that are linked to late-onset dementias. These biomarkers are proteins, which predict cognitive decline and subsequent increased risk of dementia already 20 years before the disease onset. The proteins are related to immune system dysfunction, blood-brain-barrier dysfunction, vascular pathologies, and central insulin…

Atherosclerosis: Antibodies stabilise plaque

Researchers at Karolinska Institutet have found that type IgG antibodies play an unexpected role in atherosclerosis. A study on mice shows that the antibodies stabilise the plaque that accumulates on the artery walls, which reduces the risk of it rupturing and causing a blood clot. It is hoped that the results, which are published in the journal Circulation, will eventually lead to improved…

What’s new in Cardiac Risk Testing?

It’s well known that cardiovascular disease (CVD) is the leading cause of death in the UK and worldwide. In the UK it is responsible for more than 73,000 deaths annually, affecting 1 in 6 men and 1 in 10 women.
