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,…
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…
Uwe Joseph Schoepf, Professor for Radiology, Cardiology and Paediatrics and Director of the Department of Cardiovascular Imaging at the Medical University of South Carolina, discusses areas of application for AI-based radiology. The cardiothoracic imaging expert and his team were largely involved in the development and early clinical trials of the Siemens AI-Rad Companion Chest CT, a software…
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.…
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…
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.
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…
Interventional cardiologists have been aware of the value of intracoronary (IC) imaging in clinical practice for more than twenty years. However, recent developments and improvements in modalities and software have enabled huge strides in its range and scope for both diagnostic assessment and in percutaneous coronary interventions. Imaging options now include intravascular ultrasound (IVUS),…
A remarkable number of studies and innovations were presented at the 30th anniversary of Transcatheter Cardiovascular Therapeutics (TCT) meeting in San Diego, California. TCT 2019 will take place in San Francisco, CA between 25-29-Sep-2019. On the clinical side, the long-expected results from COAPT trial studying MitraClip device in patients with secondary mitral regurgitation and heart failure…
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…
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…
Pathfast hs-cTnI is a chemi-luminescent enzyme immunoassay (CLEIA) for the quantitative measurement of cardiac troponin I (cTnI) concentration in whole blood or plasma at the point-of-care (POC). Reagents are single use in all-in-one cartridges and up to six tests in parallel can be analysed,’ the manufacturer Mitsubishi reports. ‘Low concentrations of cTnI can be analysed by using high…
Findings from a comparative outcome study have highlighted the benefits of using cardiovascular magnetic resonance imaging (CMR) perfusion imaging as a first-line ischaemia test in patients with moderate risk of coronary artery disease (CAD). The MR-INFORM (Magnetic Resonance Perfusion or Fractional Flow Reserve in Coronary Disease) trial, which began in 2012 (results published in the New England…
Traditional MRI (magnetic resonance imaging) scans use the metal gadolinium, which resonates areas of the heart muscles that are not functioning efficiently. However, gadolinium affects the Kidney function. A new 3D MRI computing technique developed by scientists at the University of Warwick calculates strain in heart muscles showing which muscles are not functioning enough without damaging other…
Areas with a higher number of fast food restaurants have more heart attacks, according to research presented at the 67th Annual Scientific Meeting of the Cardiac Society of Australia and New Zealand (CSANZ). The study also found that for every additional fast food outlet, there were four additional heart attacks per 100,000 people each year. Study author Tarunpreet Saluja of the University of…
As sea levels and temperatures rise, so does the number of heat-related heart attacks: A study published in the European Heart Journal by scientists at Helmholtz Zentrum München and colleagues from a range of other Bavarian institutions shows that the risk of suffering a heat-induced heart attack has increased significantly in recent years.
Scientists at ETH Zürich and the South African company Strait Access Technologies are using 3D printing to produce custom-made artificial heart valves from silicone. This could help meet an ageing population’s growing demand for replacement heart valves. The human heart has four chambers, each equipped with a valve to ensure blood flow in one direction only. If any of the heart valves are…
Researchers in the Medical Sciences Division of Oxford University have established a key cause of micro blood vessels constricting during surgery to reopen a blocked artery, and identified a potential therapeutic target to block the mechanism behind it. During the emergency procedure used to reopen the blocked artery causing a heart attack, smaller "micro" blood vessels can remain…
Biotronik announces the market release of its new injectable cardiac monitor (ICM), Biomonitor III, following approval in the CE region. The novel device is designed to help patients with irregular heart rhythms by documenting suspected arrhythmia or unexplained syncope with increased clarity. As the most common type of arrhythmia, 33.5 million patients worldwide suffer from atrial fibrillation…
Siemens Healthineers and Mentice AB announced the collaboration to fully integrate Mentice’s VIST Virtual Patient into the Artis icono angiography system from Siemens Healthineers. The VIST Virtual Patient thus becomes a fully integrated simulation solution for the angio-suite. The global partnership between the two companies will allow interventional radiologists, neuroradiologists, and…
People with untreated White Coat Hypertension are twice as likely to die from heart disease. Researchers at Penn Medicine say findings underscore the need for increased out-of-office blood pressure monitoring
Scientists at the German Centre for Cardiovascular Research (DZHK) have started a study to find out whether a monoclonal antibody restoring vascular integrity is safe and has positive effects on organ functions of patients with cardiogenic shock. The multicenter trial is sponsored by the University of Hamburg, financially supported by the biopharmaceutical company Adrenomed AG, and led by Dr.…
The 3D functions of the TOMTEC software package helped to establish reference values for volume ultrasound diagnosis of congenital heart defects in children.
Researchers from King's College London have found that therapy that can induce heart cells to regenerate after a heart attack.
Artificial intelligence clinics and rehab bikes, exoskeletons and stylish protections masks – healthcare in Taiwan has many faces and facets as the international medical & healthcare exhibition Medical Taiwan in Taipei will show from 27 to 30 June 2019. We visited participating companies and hospitals to give you a sneak preview of some of the highlights that might well create a buzz in…
