In almost ten per cent of myocardial infarctions, no obvious cause in the coronary artery can be found. Some of the patients are diagnosed with broken-heart syndrome, while others are left without a diagnosis. A new study from Karolinska Institutet in Sweden suggests that early magnetic resonance (MR) imaging of the heart can greatly increase the rate of diagnosis. The study has been published in the journal JACC Cardiovascular Imaging.

Limiting internet searches for investors increases stock market crash risk by 19%, a new study has found.

After a volatile weather year, scientists are finding answers as to why the past year of 2020 featured so many extreme weather and climate events in China.

Results from a retrospective observational study, reveal a 70% decline in the number of patients presenting with acute myocardial infarction (AMI) during April 2020 compared to April 2019. While the number of patients with AMI seeking care at hospitals dropped during the pandemic, those that did receive care experienced more severe symptoms because of delays in patients seeking emergency services. Findings underscore need for public education on benefit of early treatment for cardiac care.

New study presented at SCAI 2021 demonstrates HIV, mental health, obesity and substance use disorders as risk factors on most common type of heart disease in young Black patients

Whether you hanker for a hard hit of caffeine or favour the frothiness of a milky cappuccino, your regular coffee order could be telling you more about your cardio health than you think. In a world first study of 390,435 people, University of South Australia researchers found causal genetic evidence that cardio health - as reflected in blood pressure and heart rate - influences coffee consumption.

A late-breaking research presented at SCAI 2021 reveals the use of a potassium ferrate hemostatic patch (PFHP) reduces the time to hemostasis for patients receiving cardiac catherization. The findings indicate a faster approach to removing the compression band used during the procedure, without compromising safety.

Researchers at Kanazawa University examined a subset of GABA neurons in the circadian rhythm control center within the hypothalamus of the brain. They eliminated GABA signaling of vasopressin-producing neurons only in mice and found that it impaired circadian behavior. Specifically, time spent being active increased every day. Analysis showed a timing mismatch between the center's molecular clock and the behavior. Thus, GABA signaling is required to make sure the timing remains in sync.

Cells breathe, to an extent, exchanging gases, taking in energy sources from the environment and processing it. Now, researchers from Tohoku University in Japan have shone a light on the process in a new way.

The Society for Cardiovascular Angiography and Interventions (SCAI) has released an expert consensus statement providing cardiologists, cath lab directors, and hospital leadership guidance for contemporary cath lab standards. The document, "SCAI Expert Consensus Update on Best Practices in the Cardiac Catheterization Laboratory" will be presented today at the SCAI 2021 Virtual Scientific Sessions with simultaneous publication in Catheterization & Cardiovascular Interventions.

For more than a decade, ecologists have been warning of a downward trend in bumble bee populations across North America, with habitat destruction a primary culprit in those losses. While efforts to preserve wild bees in the Midwest often focus on restoring native flowers to prairies, a new Illinois-based study finds evidence of a steady decline in the availability of springtime flowers in wooded landscapes.

The formation of dead Lithium during stripping process is investigated in the whole course from the electron transfer, the conversion of Li0 to Li+ and the diffusion of Li+.

Age may influence an a human egg cell's ability to process gene products essential for the last steps of its development. The final maturation stage is critical for reproduction because it provides the material early embryos need to develop normally and survive. The researchers also found that abnormal BMI also impacted oocyte development, but through different root mechanisms compared to the fertility decline caused by age.

Scientists have identified the specific structural element of von Willebrand Factor that allows it to bind with platelets and initiate blood clotting. The team says that the specific unit, which they call the discontinuous autoinhibitory module, or AIM, is a prime site for new drug development. The work is described in an article published last week in Nature Communications, "Activation of von Willebrand factor via mechanical unfolding of its discontinuous autoinhibitory module."

A national, University at Buffalo-led study on genes in pediatric cardiomyopathy demonstrates strong evidence for routine genetic screening in children with the disease.

Pseudomonas aeruginosa biofilms have been modified to capture microplastics from water, trapping them for release and recycle.

Researchers found that a silica surface such as sand has little effect on slowing down the movement of the plastics, but that natural organic matter resulting from decomposition of plant and animal remains can either temporarily or permanently trap the nanoscale plastic particles, depending on the type of plastics. The work could lead to the development of better ways to filter out and clean up pervasive plastics from the environment.

CHARGE syndrome is a rare genetic disorder affecting about 1 in 10,000 newborns. It can lead to neurological and behavioural disorders for which no treatment is currently available. Dr. Kessen Patten and his team, from the Institut national de la recherche scientifique (INRS) have just discovered a compound that could alleviate these symptoms. The results of their research were published in the journal EMBO Reports.

Hot flashes are a hallmark of the menopause transition. Yet, they don't strike with the same frequency or severity for all women. A new study suggests that some of the same genetic factors that affect a woman's reproductive life cycle may also help predict her likelihood of having bothersome hot flashes. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
