AI-Powered Smart Bandage Heals Wounds 25% Faster
As a wound heals, it goes through several stages: clotting to stop bleeding, immune system response, scabbing, and scarring. A wearable device called "a-Heal," designed by engineers at the University of California, Santa Cruz, aims to optimize each stage of the process. The system uses a tiny camera and AI to detect the stage of healing and deliver a treatment in the form … [Read more...]
The Fat You can’t See may be Damaging Your Heart, Even if you Exercise
Excessive amounts of visceral fat -- the hidden fat surrounding organs -- is linked with faster aging of the heart, a new study has found. Aging is the biggest risk factor for heart disease, but why some people age faster than others isn't fully understood. The scientists leading the research say that visceral body fat could play an important role in accelerating aging of … [Read more...]
This New Drug could Help PTSD Patients Finally let go of Trauma
Did you know that patients with post traumatic stress disorder (PTSD) often struggle to forget traumatic memories, even long after the danger has passed? This failure to extinguish fear memories has long puzzled scientists and posed a major hurdle for treatment, especially since current medications targeting serotonin receptors offer limited relief for only a subset of … [Read more...]

Rethinking How we Study the Impact of Heat on Heart Health
When exposed to heat, the body may struggle to function normally, potentially resulting in serious cardiovascular issues. To cool down, the body increases blood flow to the skin, leading to higher heart rates and increased cardiac workloads. The resultant increase in strain on the heart can pose a significant risk for vulnerable groups, including older adults and individuals … [Read more...]

An average of four minutes of incidental vigorous physical activity a day could almost halve the risk of major cardiovascular events, such as heart attacks, for middle-aged women who do not engage in structured exercise, according to new research from the University of Sydney, published in the British Journal of Sports Medicine. "We found that a minimum of 1.5 minutes to … [Read more...]
Invention Quickly Detects Earliest Sign of Heart Attack
"Heart attacks require immediate medical intervention in order to improve patient outcomes, but while early diagnosis is critical, it can also be very challenging -- and near impossible outside of a clinical setting," said lead author Peng Zheng, an assistant research scientist at Johns Hopkins University. "We were able to invent a new technology that can quickly and accurately … [Read more...]
Study Proposes New Heart Failure Treatment Targeting Abnormal Hormone Activity
In heart failure, which is considered a global pandemic, the heart can no longer pump blood effectively. In HFpEF, the heart can pump normally but its muscles are too stiff to relax to re-fill the chambers with blood properly. It is often seen in older adults and people with multiple risk factors including high blood pressure (hypertension), obesity and diabetes. They … [Read more...]

Benefits of Adolescent Fitness to Future Cardiovascular Health Possibly Overestimated
There is a well-known relationship between good physical fitness at a young age and a lower risk of cardiovascular disease later in life. However, when researchers adjusted for familial factors by means of sibling analysis, they found a weaker association, although the link between high body mass index (BMI) and cardiovascular disease remained strong. The study, which was … [Read more...]
Measuring Long-Term Heart Stress Dynamics with Smartwatch Data
Biomedical engineers at Duke University have developed a method using data from wearable devices such as smartwatches to digitally mimic an entire week's worth of an individual's heartbeats. The previous record covered only a few minutes. Called the Longitudinal Hemodynamic Mapping Framework (LHMF), the approach creates "digital twins" of a specific patient's blood flow to … [Read more...]
Not Getting Enough Sleep? Your Vascular Cells are Drowning in Oxidants
Does this sound like you? You wake up at the same time each morning, get the kids out the door, and rush to catch the subway to work. But at night, maybe you stay up until midnight doing laundry or 1 a.m. to catch up on the bills. Lots of Americans -- about one-third of us -- are in the same situation and habitually get only five to six hours of sleep instead of the … [Read more...]
