First look at the ‘molecular switch’ that makes our heart beat

Oxford University Radcliffe Department of Medicine researchers have developed a new method that uses a protein originally found in marine corals to visualise the flow of calcium that makes the heart beat. In a paper published in the journal Circulation Research, they used this technique to uncover the effects of genetic errors that contribute to a heart condition that is the leading killer of…

Predicting the aneurysm risk for kids with Kawasaki disease

When Olivia Nelson was 3 years old, her parents noticed that she had a fever that wouldn’t get better. They brought her to a nearby hospital, where she spent about two weeks being screened for diseases. As doctors tried to find a diagnosis, a lymph node on Olivia’s neck became swollen. Alarmed and wanting an answer, the Nelsons asked to transfer to Seattle Children’s. “It was very…

Prediabetes: don't wait, reduce your CVD risk

A diagnosis of prediabetes should be a warning for people to make lifestyle changes to prevent both full-blown diabetes and cardiovascular disease (CVD), according to scientists at Wake Forest School of Medicine. “We know that having diabetes increases the risk of developing cardiovascular disease, so in our study we wanted to determine what the absolute risk or probability of developing heart…

New device for screening arterial stiffness and diagnosing CVD

Researchers have developed a prototype medical device based on silicon photonics for the screening of arterial stiffness and for the diagnosis of cardiovascular diseases such as arterial stenosis and heart failure. This is a cooperation between imec, the world-leading research and innovation hub in nanoelectronics and digital technology and Ghent University, together with Medtronic and other…

CVD: Every second to third premature death preventable

Of the 4.3 million cardiovascular deaths in Europe in 2016, 2.1 million were the result of poor nutrition. The 28 EU member states account for around 900,000, Russia for 600,000 and the Ukraine for 250,000 of these deaths. Every second to third premature cardiovascular death could be prevented by better nutrition. These were the findings of an international research team led by the Martin Luther…

Finding the 'fingerprint' of cardiovascular disease

Forty-two percent of all deaths in the United States are related to cardiovascular disease (CVD). According to the Global Cardiovascular Drugs Market Forecast, by 2030 the number of deaths from CVD will rise to 23.6 million per year in the U.S. alone. Along with increased deaths, spending on drugs to treat CVD as well as related hospital stays, home health care and lost productivity will also…

Wearable ultrasound patch penetrates the skin to measure blood pressure

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) are literally breaking barriers using ultrasound waves emitted from a flexible patch to accurately measure central blood pressure and help detect cardiovascular problems earlier. For a while now, smart, wearable devices have had the ability to capture how many steps we take in a day or measure our heart…

Treating post-stroke depression with magnetic fields

Obstetricians and midwives often warn new mothers about postpartum depression. They might mention what symptoms women should look out for—such as crying spells or extreme irritability—and where they can turn for help. But people who have strokes may not learn that they, too, are at risk for depression. Post-stroke depression stems from the cardiovascular changes in the brain that lead to a…

Cholesterol-lowering medication

Statins overprescribed for primary prevention

Taking cholesterol-lowering drugs, or statins, as a preventive measure can reduce the risk of cardiovascular disease. A study by the University of Zurich now shows that this measure is recommended too often, as current guidelines fail to take into account the risks of side effects. Even healthy people who don't suffer from a cardiovascular disease are prescribed statins if they meet certain risk…

AI system screens early Phase AFib

Here at Medica, the Taiwanese start-up Maisense is demonstrating Freescan, its artificial intelligence (AI) based solution to screen for stroke through the early detection of atrial fibrillation (AFib). Speaking of the system’s aims, Maisense summed up this huge health problem. ‘Every four minutes, someone dies of stroke. Thirteen percent of these are classified as haemorrhagic stroke. When…

The future POCT heart attack test

Experts report that a new blood test to diagnose heart attacks could be carried out on a hand-held device in the not-too-distant future. The test, devised by a team at Kings College London, uses similar technology to the troponin test, but instead analyses cardiac myosin-binding protein C (cMyC). In research presented at the British Cardiovascular Society conference in Manchester, UK, this June,…

The role of nanomedicine in CV diagnosis

Nanomedicine will play an increasingly important role in future diagnosis and treatment of cardiovascular disease, a subject explored in detail by four expert speakers at the British Cardiovascular Society conference in Manchester in June. The conference heard that the technology – dealing with dimensions and tolerances of less than 100 nanometres, especially the manipulation of individual…

ESC 2018: At the heart of research

When delegates from around 150 countries converge on Munich for ESC Congress 2018 they will no doubt reflect on what they themselves eat. Yes, nutrition is up for debate, questioning, for example, whether weight loss therapies can also prevent heart attacks and strokes. Results from the CAMELLIA-TIMI 61 trial of 12,000 overweight individuals with established cardiovascular disease or diabetes…

Daily salt intake: How much is too much for our heart?

New research shows that for the vast majority of individuals, sodium consumption does not increase health risks except for those who eat more than five grams a day, the equivalent of 2.5 teaspoons of salt. Fewer than five per cent of individuals in developed countries exceed that level. The large, international study also shows that even for those individuals there is good news. However, the…

How being transgender affects cardiac health

Transgender individuals may be at higher risk for myocardial infarction and death due to cardiovascular disease, according to several studies. This increased risk may be due to the hormone therapy that transgender patients take for masculinization or feminization. A review authored by Michael S. Irwig, MD, associate professor of medicine at the George Washington University (GW) School of Medicine…

Google AI now can predict cardiovascular problems from retinal scans

Google AI has made a breakthrough: successfully predicting cardiovascular problems such as heart attacks and strokes simply from images of the retina, with no blood draws or other tests necessary. This is a big step forward scientifically, Google AI officials said, because it is not imitating an existing diagnostic but rather using machine learning to uncover a surprising new way to predict these…

One cigarette a day can't do much harm – or can it?

Smoking just one cigarette a day carries a much higher risk of developing coronary heart disease and stroke than expected – about half the risk of smoking 20 per day –concludes a University College London (UCL)-led review of the evidence. The researchers say their findings, published in the BMJ, have important consequences for many smokers and health professionals who believe that smoking…
