App reminds heart patients to take their pills

Heart patients using a smartphone app reminder are more likely to take their medication than those who receive written instructions, according to a study presented at the 45th Argentine Congress of Cardiology (SAC 2019) in Buenos Aires. ‘We hypothesised that the app would increase adherence by 30%, but the impact was even greater,’ said study author Dr Cristian M. Garmendia, of the…

New ways to treat severe aortic stenosis

New research at the University of Leicester, funded by the British Heart Foundation (BHF), could change the way people living with a debilitating heart condition are treated. The £2.7m clinical trial aims to identify the best time to operate on people living with severe aortic stenosis (AS). AS is a common condition that causes a narrowing of the heart valve, restricting blood flow out of the…

AI identifies genes linked to heart failure

The Queen Mary University of London team applied an artificial intelligence (AI) technique to analyse the heart MRI images of 17,000 healthy UK Biobank volunteers. They found that genetic factors accounted for 22-39 per cent of variation in the size and function of the heart’s left ventricle, the organ’s main pumping chamber. Enlargement and reduced pumping function of the left ventricle can…

SULEEI: extending the functional lives of biological heart valve prostheses

For decades now, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing processes and systems for cleaning, sterilization, and surface modification. The newly in-house developed process, called SULEEI, makes it possible to sterilize (S) and preserve decellularized pericardial tissue by means of photo-initiated ultraviolet (U) crosslinking…

Vascular surgery

New lease of life thanks to new aorta

Patients with the rare Loeys-Dietz syndrome suffer from aortic enlargement which may result in sudden over-expansion and a fatal aortic tear. In order to prevent this from happening, an aortic prosthesis must be implanted. A team of vascular surgeons at the University Hospital of Zurich was one of the first in the world to risk undertaking this life-saving operation on a child as an emergency…

Neural network approach to ECG

AI detects heart failure from a single heartbeat

Researchers have developed a neural network approach that can accurately identify congestive heart failure with 100% accuracy through analysis of just one raw electrocardiogram (ECG) heartbeat, a new study reports. Congestive heart failure (CHF) is a chronic progressive condition that affects the pumping power of the heart muscles. Associated with high prevalence, significant mortality rates and…

Reopening blood vessels

Microbubbles and ultrasound can help treat heart attacks

Doctors are using microbubbles and ultrasound to treat heart attacks – deploying these traditional diagnostic tools in an attempt to reopen tiny blood vessels, reduce scar size and restore heart function, according to a study described at a medical conference in Chicago. “This study shows for the first time that microbubbles can be used to both diagnose and treat small vessel obstructions…

Using AI to predict heart attacks

Technology developed using artificial intelligence (AI) could identify people at high risk of a fatal heart attack at least five years before it strikes, according to new research funded by the British Heart Foundation (BHF). The findings are being presented at the European Society of Cardiology (ESC) Congress in Paris and published in the European Heart Journal. Researchers at the University of…

The XX factor

XX chromosomes put women's hearts at risk

New research at the University of Kentucky has confirmed that the presence of XX sex chromosomes increases the amount of fat circulating in the blood, which leads to narrowing of the arteries and ultimately a higher risk of heart attacks and coronary artery disease. The research was published in Nature Communications. The leading cause of death in women is coronary artery disease (CAD), but women…

‘Smart’ approach to AF

mHealth to help detect atrial fibrillation

A new study, presented as ‘Late Breaking Science’ at the European Society of Cardiology (ESC) annual congress, highlights the feasible use of mobile health (mHealth) devices to help with the screening and detection of atrial fibrillation (AF), a common heart condition. AF causes an irregular and sometimes, abnormally fast heart rate. The heart’s upper chambers (atria) contract randomly and…

After myocardial infarction

Patching up a damaged heart

Scientists in the UK have developed tiny patches of engineered heart tissue that have the potential to be implanted to help people recover from a heart attack. Measuring approximately 3cm x 2cm, the patches contain up to 50 million human-induced pluripotent stem cell derived cardiomyocytes (hiPSC-CM). Yet, these are programmed to turn into working heart muscle that can beat and gradually be…

Cell combination heals damaged hearts

Researchers have discovered a unique combination of cells grown from stem cells that could prove pivotal in helping a heart regenerate after a patient has suffered a myocardial infarction. The University of Cambridge research team found that transplanting an area of damaged tissue with a combination of heart muscle cells and supportive cells, similar to those that cover the outside of the heart,…

Cardio-controversy: Added value through CAD imaging?

ESC Congress, Paris: Two key strands in the ‘Controversies in imaging coronary artery disease’ session at the congress will examine the pros and cons of imaging use for coronary artery disease risk stratification in asymptomatic patients; the second strand will focus on whether CT angiography should be the first choice for imaging coronary artery disease in patients with stable chest pain.…

Software lets surgeon see real-time 3D map of heart

Innovative software that allows a surgeon to view inside a patient’s heart in real time while applying treatment has been used for the first time in the UK in operations at the National Institute for Health Research (NIHR) Leicester Biomedical Research Centre (BRC). University of Leicester Professor and Leicester’s Hospitals Cardiologist Andre Ng used the new technique in operations on two…

MRI shows cardiac diagnostic value

Cardiovascular magnetic resonance (CMR) imaging has become faster, simpler and more widely available in recent years because it has evolved to deliver effective assessment and diagnosis of a range of heart conditions with expanding guideline indications. ‘MRI is the reference test for anatomical imaging of the heart, for quantifying chamber sizes and function,’ explains Professor Sven Plein,…

Why exercise is even more beneficial for CVD patients

A study of nearly half a million people has found for the first time that those with heart or blood vessel problems benefit more from having a physically active lifestyle than do healthy people without cardiovascular disease (CVD). Increased physical activity reduced the risk of dying during a six-year follow-up period for people with and without CVD, but the researchers found the greatest…

Healing the heart’s right chambers

Most people think their heart is located on the left side of their chest, and this is also the direction science has looked, so far. However, just as the heart sits at the centre of the chest, disease also affects the right side of the organ. Cardiologists must now look right to improve patient prognosis, according to Professor José Luis Zamorano, Vice President of the European Society of…

Implantable cardiac monitor gets diagnosis in just three days

It started as a fairly typical case: The 79-year-old patient had suffered unexplained dizziness for years. To diagnose why, the cardiology team at Sweden’s Kalmar Hospital performed echocardiograms, Holter ECGs and other tests. However, these tests showed normal sinus rhythm and thus were inconclusive. Dr Hendrik Schreyer, Dr David Olsson and Professor Jörg Carlsson decided to use…
