Our gut microbiome could unlock the secret to healthy ageing

Bacteria and other microorganisms in the digestive tract are linked with dozens of health conditions including high blood pressure, high blood lipids, and body mass index (BMI) according to research presented at ESC Congress 2020. “Our study indicates that microbiota might have an important role in maintaining health and could help us develop novel treatments,” said study author Dr. Hilde…

Remote cardiac monitoring

For cardiology patients fitted with an implantable cardiac monitor, cardioverter defibrillator (ICD) or pacemaker, home monitoring is a blessing. The system also has many advantages for medical staff, as Kristina Rauholt reports. The nurse and Certified Cardiac Device Specialist for Allied Professionals (CCDS) at the Sahlgrenska University Hospital, in Sweden, has worked with home monitoring…

Gender parity

Why heart failure research needs more female authors

While about a quarter of physicians and researchers working in advanced heart failure (HF) and transplant cardiology are women, representation of women leading HF research remains limited, according to new research led by Penn Medicine. The authors say the findings point to a need to support great gender diversity among researchers to drive diversity among clinical trial participants and even…

Predicting longevity in heart failure patients - by looking at their eyes

Pupil size predicts death and hospital readmission in patients with heart failure, according to new research. “Our results suggest that pupil area is a novel way to identify heart patients at elevated risk of death or hospital readmission,” said study author Dr. Kohei Nozaki of Kitasato University Hospital, Kanagawa, Japan. “This provides an opportunity to intervene and improve outlook.”

Shedding light into the 'black box' of AI

Neural network helps explain relapses of heart failure patients

Patient data are a treasure trove for AI researchers. There’s a problem though: many algorithms used to mine patient data act as black boxes, which makes their predictions often hard to interpret for doctors. Researchers from Eindhoven University of Technology (TU/e) and the Zhejiang University in China have now developed an algorithm that not only predicts hospital readmissions of heart…

Smart watches and fitness trackers: useful, but may increase anxiety

Is my heart beating slightly fast? Is a heart attack coming? I didn’t sleep as much as I thought I had last night – is that bad for my heart? Health apps and fitness watches can shed considerable light on how our bodies work and make recommendations for a healthy lifestyle. However, self-measuring can have a downside too, according to a new study that examined the experiences of 27 heart…

Irregular heartbeat treatment

Holograms help physicians during cardiac procedures

Bringing a little bit of science fiction into an operating room, a team of engineers and physicians at Washington University in St. Louis has shown for the first time that using a holographic display improves physician accuracy when performing a procedure to treat irregular heartbeat. Jennifer N. Avari Silva, MD, associate professor of pediatrics at the School of Medicine, and Jonathan Silva,…

3D microprinted scope

World’s smallest imaging device focuses on heart disease

A team of researchers led by the University of Adelaide and University of Stuttgart has used 3D micro-printing to develop the world’s smallest, flexible scope for looking inside blood vessels. The camera-like imaging device can be inserted into blood vessels to provide high quality 3D images to help scientists better understand the causes of heart attack and heart disease progression, and could…

Surprising find

More than half of heart scans abnormal in hospitalised COVID-19 patients

Half of COVID-19 patients who received a heart scan in hospital showed abnormalities in heart function, according to new research funded by the British Heart Foundation (BHF). The study, published in the European Heart Journal - Cardiovascular Imaging, found that around one in seven showed severe abnormalities likely to have a major effect on their survival and recovery. It also showed that one…

30 years after reunification, health disparities still exist

Germany: reunited but still divided (in healthcare)

East Germany has many more hospitalisations for heart failure compared to West Germany despite a nationwide healthcare system, according to research presented today on HFA Discoveries, a scientific platform of the European Society of Cardiology (ESC). Heart failure is the most common reason for hospital admissions and is responsible for a large part of the total health expenditure on…

New heart valve could transform open heart surgery

A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team's latest in-vitro results, published in Biomaterials Science, suggest that the…

Digital health: guardian angel or 'Big Brother'?

Cardiologist Professor Martin Cowie raised an important issue during a session to examine the challenges of the Digital Cardiovascular Health Revolution, held at the European Society of Cardiology Congress 2019 in Paris. In his presentation ‘Future impact of digital health on patients – guardian angel or big brother?’, he confirmed that, within digital health transformation, the role of…

App detects fluid in the lungs via voice recordings

Voice analysis by a smartphone app identifies lung congestion in heart failure patients, allowing early intervention before their condition deteriorates. The small study is presented on HFA Discoveries, a scientific platform of the European Society of Cardiology (ESC). “Speech is personal and as such, very small changes (related to the same person) can be detected – for example, the ability…

Heart attacks, heart failure, stroke

COVID-19’s cardiovascular complications

COVID-19 can cause serious cardiovascular complications including heart failure, heart attacks and blood clots that can lead to strokes, emergency medicine doctors at the University of Virgina report in a new scientific paper. They also caution that COVID-19 treatments can interact with medicines used to manage patients’ existing cardiovascular conditions.
