Soft Skin Patch could provide early warning for Strokes, Heart Attacks

Two fingers press down on a soft, electronic patch against the skin.
This soft, stretchy skin patch uses ultrasound to monitor blood flow to organs like the heart and brain. This image was selected as the cover image for the July 2021 issue of Nature Biomedical Engineering.

Engineers at the University of California San Diego developed a soft and stretchy ultrasound patch that can be worn on the skin to monitor blood flow through major arteries and veins deep inside a person’s body.

Knowing how fast and how much blood flows through a patient’s blood vessels is important because it can help clinicians diagnose various cardiovascular conditions, including blood clots; heart valve problems; poor circulation in the limbs; or blockages in the arteries that could lead to strokes or heart attacks.

The new ultrasound patch developed at UC San Diego can con...

One Cup of Leafy Green Vegetables a Day Lowers Risk of Heart Disease

New ECU research has shown eating one cup of nitrate-rich vegetables each day significantly reduces the risk of heart disease

New Edith Cowan University (ECU) research has found that by eating just one cup of nitrate-rich vegetables each day people can significantly reduce their risk of heart disease.

The study investigated whether people who regularly ate higher quantities of nitrate-rich vegetables, such as leafy greens and beetroot, had lower blood pressure, and it also examined whether these same people were less likely to be diagnosed with heart disease many years later.

Cardiovascular diseases are the number one cause of death globally, taking around 17.9 million lives each year.

Researchers examined data from over 50,000 people residing in Denmark taking part in the...

Mayo Clinic researchers have uncovered stem cell-activated mechanisms of healing after a heart attack. Stem cells restored cardiac muscle back to its condition before the heart attack, in turn providing a blueprint of how stem cells may work.

The study, published in NPJ Regenerative Medicine, finds that human cardiopoietic cells zero in on damaged proteins to reverse complex changes caused by a heart attack. Cardiopoietic cells are derived from adult stem cell sources of bone marrow.

“The extent of change caused by a heart attack is too great for the heart to...

Reversing Tissue Damage caused by Heart Attacks?

‘The adipokine leptin modulates adventitial pericyte functions by autocrine and paracrine signalling’ by Paolo Madeddu et al in Scientific Reports

A new discovery by University of Bristol scientists helps to explain how cells which surround blood vessels, pericytes, stimulate new blood vessels to grow with the hormone ‘leptin’ playing a key role. Leptin is produced by fat cells which helps to regulate energy balance in the body by inhibiting the appetite. This study, described in Scientific Reports, may have important implications for the treatment of heart attacks and also for cancer, the two main killers in the UK.

The growth of new blood vessels, ‘angiogenesis’, is an important process occurring both in health and disease...
