A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Formulary restrictions may increase the risk of stroke in patients with atrial fibrillation

Atrial fibrillation (AF) is a major risk factor for stroke, and for decades the anticoagulant warfarin was the standard treatment for lowering that hazard. However, numerous drug and food interactions make warfarin burdensome for patients.

Neuronal cilia are important for dopamine receptor 1 signaling, study shows

A historically overlooked rod-like projection present on nearly every cell type in the human body may finally be getting its scientific due: A new study has found that these appendages, called cilia, on neurons in the brain have a key role in ensuring a specific dopamine receptor's signals are properly received.

Does loneliness affect the brain and heart?

Scientists review studies to determine the effects of social isolation and loneliness on brain health and cardiovascular conditions.

Brain-robot interfaces may help the brain reroute motor pathways damaged during stroke

Brain-robot interfaces - apparatuses where brain activity controls the movements of a robotic device that supports a hand or limb - show promise in rehabilitating paralyzed stroke patients.

Fatigue and headache among the most common symptoms following COVID-19 infections

Fatigue and headache were the most common symptoms reported by individuals an average of more than four months out from having COVID-19, investigators report.

Wrist-wearable devices more cost-effective than electrocardiograms and pulse palpation for atrial fibrillation screening

Screening individuals for atrial fibrillation (AF) using wearable devices is more cost-effective than screening using conventional methods such as 12-lead electrocardiogram (ECG) and pulse palpation, or than no screening at all, researchers from Massachusetts General Hospital (MGH) have found.

Optically controlled local heat-pulse method manipulates temperature in cells

A team of researchers led by Osaka University finds that mutant variants of the calcium channel protein RyR1 are hypersensitive to heat, which creates a positive feedback loop of calcium release and leads to malignant hyperthermia

French study on cardiovascular disease incidence during COVID pandemic and vaccination campaign

Researchers describe failures of the French healthcare system as reflected by increased hospitalizations due to certain acute cardiovascular diseases in 2021.

Digital support tool helps reduce alcohol intake

A digital support tool on your phone can help if you want to reduce your alcohol consumption. This has been shown in a study by researchers at Linköping University. They have developed and evaluated a digital tool which helps individuals reduce their alcohol intake on their own.

Children are less fit and more obese than ever before, study says

Record levels of obesity and physical inactivity among children mean they are set to bear the brunt of poorer health effects from rising global temperatures – that's the stark warning in a new comprehensive review of current studies on the topic.

Heart failure arises from mutations in distinct genes, study finds

Heart failure is a common and devastating disorder for which there is no cure. Many cardiomyopathies - conditions that make it difficult for the heart to pump blood such as dilated cardiomyopathy (DCM) and arrhythmogenic cardiomyopathy (ACM) - can lead to heart failure, but treatments for patients with heart failure do not take these distinct conditions into account.

Higher suPAR levels linked with increased risk of blood clot formation

Blood clots are thought to occur in as many as a third of patients hospitalized with COVID-19. In many cases these clots can be deadly, such as pulmonary embolisms - blood clots that travel to the lungs. In fact, in nearly one third of patients with COVID-19, these clots led to death.

‘Children are not little adults’ and need special protection during heat waves

After more than a week of record-breaking temperatures across much of the country, public health experts are cautioning that children are more susceptible to heat illness than adults are — even more so when they're on the athletic field, living without air conditioning, or waiting in a parked car.

UVA researchers receive $15 million from LeDucq Foundation to advance understanding of atherosclerosis

The Boston-based LeDucq Foundation has awarded $15 million to researchers at UVA Health and their collaborators to advance our understanding of atherosclerosis, or hardening of the arteries, and find better ways to treat it.

What are the recommendations to prevent obesity in midlife women?

Researchers developed recommendations for counseling non-obese 40 to 60 years old women with body mass index (BMI) values ≤29.9 kg/m2 for obesity prevention.

Substantial increases in cardiovascular trends contribute to a rising burden on the US health care system

By the year 2060, projected rates of cardiovascular risk factors and disease will increase significantly in the United States, according to a study published today in the Journal of the American College of Cardiology. Substantial increases in cardiovascular trends may contribute to a rising burden on the U.S. health care system and highlight the need for equitable access to prevention education and treatments now to prevent future disease.

Gout flares associated with subsequent cardiovascular events

Experts at the University of Nottingham, in collaboration with experts at Keele University, have found that the risk of heart attacks and strokes temporarily increases in the four months after a gout flare.
