The heart's motion is so powerful that it can recharge devices that save our lives, according to new research from Dartmouth College. Using a dime-sized invention developed by engineers at the Thayer School of Engineering at Dartmouth, the kinetic energy of the heart can be converted into electricity to power a wide-range of implantable devices, according to the study funded by the National…
Longer hours, more demanding working practices, complex cases and increased administration are taking their toll on physicians as growing numbers, across a range of specialties, report signs of burnout. All this despite technological advances such as artificial intelligence and machine learning to aid diagnosis, read and interpret images, improve workflow and enhance decision-making.
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…
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…
Patients who undergo heart surgery do not experience major memory changes—either better or worse—when compared with those who have a much less invasive, catheter-based procedure, according to a study published online in The Annals of Thoracic Surgery. “It was comforting to see that the differences in cognitive decline between the two heart procedures are small, even though one involves…
A new cardiac ultrasound solution is harnessing the power of anatomical intelligence to offer greater diagnostic confidence to clinicians. New EPIQ cardiac ultrasound solutions launched by Philips during the 2018 ESC Congress in Munich, have been designed to simplify workflow The CVx platform which, the firm reports, includes higher processing power, improved image clarity and sharpness, and more…
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…
New 7-Tesla MR methods could potentially shed light on cardiomyopathies’ principles, according to a leading French radiologist who also stresses the importance of teamwork between radiologists, cardiologists, surgeons and anaesthesiologists. Morphologic and dynamic information of the myocardium is achieved with millimetric resolution (0.9x0.9 square mm). Strong intensity variations…
Built as the first commercially available scanner to deliver truly digital PET, the Vereos PET/CT, from Philips, offers revolutionary Digital Photon Counting technology. The science behind this scanner evolution is ‘quite complicated’, agrees Piotr Maniawski, Director of Clinical Science Nuclear Medicine at Philips Healthcare, yet the improved performance is significant, particularly when…
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…
Cardiologists in the UK are trialling an artificial intelligence (AI) system that will help better diagnose heart disease. Devised by researchers from the University of Oxford, it can predict heart disease and cardiac events from ultrasound stress test images with initial results showing that the AI system is far more accurate than conventional techniques. Paul Leeson, Professor of Cardiovascular…
The IN-TIME study remains the only major trial to show a clear mortality benefit for remote monitoring in heart failure (HF) patients. A recent analysis by Hussar et al. suggests workflow processes such as daily, multiparametric data transmitted using Biotronik Home Monitoring, may be key to this benefit. Dr Wilfried Mullens, Head of the Heart Failure and Cardiac Rehabilitation Section at…
Nanomedicine is set to play an increasingly important role in the future diagnosis and treatment of cardiovascular disease. Understanding the importance of nanomedicine was enhanced by four experts who spoke at the British Cardiovascular Society conference held in June. The technology – dealing with dimensions and tolerances of less than 100 nanometres and especially the manipulation of…
Men with diabetes are 2.4 times more likely than non-diabetics to suffer heart failure and women are five times more likely. But why? A new Loyola University Chicago Stritch School of Medicine study reveals how, on a cellular level, diabetes can cause heart failure. The findings could lead to medications to treat and perhaps prevent heart failure in diabetes patients, researchers said. In a…
Researchers at Cleveland Clinic, University of Oxford, and University of Erlangen have identified a novel imaging biomarker – and found it can be used to predict all-cause and cardiac mortality by measuring inflammation of fatty tissue surrounding the coronary arteries.
A range of new biomarkers and diagnostics for precision cardiovascular medicine were outlined in a session at the British Cardiovascular Society annual conference held recently in Manchester. Speakers from King’s British Heart Foundation Centre looked at how mass spectrometry allows clinicians to measure large numbers of proteins simultaneously, discussed a new biomarker for cardiac ischaemia…
Machine learning is increasingly helping radiologists to acquire faster and better quality images, and measure heart function. This is just the tip of the iceberg; artificial intelligence has far more to bring to the heart, explained Daniel Rueckert, Head of the Department of Computing at Imperial College London, during CMR 2018. Machine learning (ML) is becoming a valuable assistant for…
Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart — a discovery that potentially can lead to new insight into medical problems such as heart arrhythmia and sudden cardiac death.
Intracardiac echocardiography (ICE) is an increasingly important guiding tool for structural heart disease interventions – without general anaesthesia. José Ribeiro, who works in the thorax and circulation unit at Gaia Hospital Centre, Portugal, who has worked with this technology for the past two years, explained its benefits and limitations.
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,…
One of the challenges for every echocardiography lab is the technically difficult patient. Conventionally, labs use contrast agents to enhance endocardial border visualization. The application of contrast agents increases the exam time, resources and costs. Additionally, the use of contrast turns a previously non-invasive exam into an invasive procedure. Hitachi Healthcare has now developed a…
As the world’s largest cardiology congress gets underway in Munich, it’s worth looking back to previous ESC sessions to see how scientific debates have evolved. At ESC 2016, held in Rome, REM-HF investigators presented data suggesting remote monitoring in implantable cardiac devices offered no added clinical benefit. Two years on, there are new reasons to re-examine that conclusion, with a…
MRI has a central role in picking up myocardial infarction with non-obstructive coronary disease, a condition that particularly affects women but is often left untreated, with potentially fatal outcome. Heart attack in women presents differently than in men and requires a different approach when it comes to detection and prevention, according to cardiologist Allison Hays.
A major study has been launched to investigate the interaction between genes and lifestyle factors and dilated cardiomyopathy (DCM). Led by Professor Stuart Cook, at the National Heart and Lung Institute, this, the largest ever DCM study, will investigate why people develop DCM, with a focus on who is most at risk of sudden death or heart failure (HF). Six hospital trusts across England –…
Intervention in ventricular arrhythmia has improved dramatically over the past three decades thanks to advances in imaging and cooperation between cardiology and radiology, according to Professor Josep Brugada MD, director of the paediatric arrhythmia unit at Sant Joan de Déu Hospital in Barcelona. ‘Echocardiography, CT and MRI, combined with cardiology,’ he said, ‘have revolutionised the…
