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.
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…
The use of troponin assays to rule in or rule out myocardial infarction (MI) rapidly is critical on several levels. The quick result can reassure the patient that they have not had a heart attack and can return home safely; or, in the event of MI, the relevant treatment can start very soon. It also ensures that clinicians can make the right decision with confidence. Troponin levels have been the…
Researchers from King's College London have found that therapy that can induce heart cells to regenerate after a heart attack.
Researchers at Karolinska Institutet have found that type IgG antibodies play an unexpected role in atherosclerosis. A study on mice shows that the antibodies stabilise the plaque that accumulates on the artery walls, which reduces the risk of it rupturing and causing a blood clot. It is hoped that the results, which are published in the journal Circulation, will eventually lead to improved…
Cancel the cheese omelet. There is sobering news for egg lovers who have been happily gobbling up their favorite breakfast since the 2015-2020 Dietary Guidelines for Americans no longer limited how much dietary cholesterol or how many eggs they could eat. A large, new Northwestern Medicine study reports adults who ate more eggs and dietary cholesterol had a significantly higher risk of…
A day case catheter ablation procedure which includes only the bare essentials and delivers the same outcomes could slash waiting lists for atrial fibrillation patients, according to late-breaking results from the AVATAR-AF trial presented today at EHRA 2019, a European Society of Cardiology (ESC) congress. With the simplified protocol, 30% more patients could receive catheter ablation for the…
Scientists at Newcastle University believe it may be possible to reverse the damage in the heart caused by ageing. New research, which has been published in the journal EMBO, could suggest a new way of preventing heart failure in older patients. Heart failure occurs when the heart is not pumping blood around the body as well as it should, most commonly when the heart muscle has been damaged –…
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.
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,…
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.
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…
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…
Patients’ own immune response has the potential to prevent the development and progression of heart failure, according to research presented at Frontiers in CardioVascular Biology (FCVB) 2018, a European Society of Cardiology congress. The study found antibodies in the plasma and heart muscle of end-stage heart failure patients. “The role of the immune response in the development of heart…
Scientists used an experimental targeted molecular therapy to block a matrix-forming protein in heart cells damaged by heart attack, reducing levels of scarred muscle tissue and saving mouse models from heart failure. Researchers at the Cincinnati Children’s Heart Institute report in the journal Circulation testing a manufactured peptide called pUR4 to block the fibronectin protein in human…
Walking 10,000 steps a day or a doing a quick workout from a phone app - all of those tactics could work to reduce risk of disease and death, according to new research. The study found that even brief trips up and down stairs would count toward accumulated exercise minutes and reducing health risks so long as the intensity reaches a moderate or vigorous level. The most dramatic improvements in…
An Italian law requiring citizens to hold a certificate to use a defibrillator must change to improve survival from cardiac arrest, researchers argued today at Acute Cardiovascular Care 2018, a European Society of Cardiology congress. “Automated external defibrillator (AED) use before the arrival of the emergency medical services (EMS) plays a key role in improving victim survival from…
Standard medical tests miss nearly two-thirds of heart attack diagnoses, reveals research presented at CMR 2018. “Unrecognised MI has a poor short-term prognosis but until now the long-term outlook was unknown,” said lead author Dr Tushar Acharya, a cardiologist at the National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, US. “This study investigated long-term…
Radiation therapy often is used to treat cancer patients. Now, doctors at Washington University School of Medicine in St. Louis have shown that radiation therapy — aimed directly at the heart — can be used to treat patients with a life-threatening heart rhythm. They treated five patients who had irregular heart rhythms, called ventricular tachycardia, at the School of Medicine. The patients…
Coordinating the response to heart attacks among emergency responders and hospitals reduces the time to treatment and saves lives - even on a large, regional scale, according to a study led by the Duke Clinical Research Institute with support from the American Heart Association. In the largest demonstration of the coordinated approach - 132 hospitals and 946 EMS agencies in 12 U.S. regions -…
A new blood test to detect heart attacks has been developed by a team of researchers at King’s College, London, which could speed up diagnosis, according to results from pan-European trials. The test is quicker than the standard test, which combines an ECG with a blood test to measure the levels of troponin. Under current guidelines, suspected heart attack cases are tested for high blood…
University of Alabama at Birmingham biomedical engineers report a significant advance in efforts to repair a damaged heart after a heart attack, using grafted heart-muscle cells to create a repair patch. The key was overexpressing a gene that activates the cell-cycle of the grafted muscle cells, so they grow and divide more than control grafted cells.
Early research results suggest scientists might be on to a way to preserve heart function after heart attacks or for people with inherited heart defects called congenital cardiomyopathies. Researchers at the Cincinnati Children’s Heart Institute report in Nature Communications that after simulating heart injury in laboratory mouse models, they stopped or slowed cardiac fibrosis, organ…
A new type of scan that can detect cardiac inflammation may help tailor treatment for patients who have suffered a heart attack, according to research findings presented at the British Cardiovascular Society (BCS) conference in June.
The ADVIA Centaur® High-Sensitivity Troponin I (TNIH) assay* is the latest addition to Siemens Healthineers’ comprehensive cardiac menu to assist clinicians with the diagnosis and treatment of chest pain patients.
