Health 4 June 2019 By New Scientist Staff and Press AssociationHeart patches could provide a lifeline for hundreds of thousands of people after a heart attack. The patches are grown in a lab and could one day provide a way to help repair damaged hearts. Each patch consists of a thumb-sized piece of heart tissue (measuring 3 centimetres by 2 centimetres) contain up to 50 million human stem cells, programmed to turn into working heart muscle cells that beat. One or more patches could be implanted on to the heart of a someone who has had a heart attack to prevent or even reverse damage to the organ. During a heart attack, the heart is starved of vital nutrients and oxygen, killing off parts of the heart muscle. This weakens the heart and can eventually lead to heart failure, which affects an estimated 920,000 people in the UK. Advertisement Once sewn in place, the new patches are intended to physically support the damaged heart muscle and help it pump more efficiently. The … [Read more...] about Stem cell patch may help repair damage caused by heart attacks

For people who survive a heart attack, the days immediately following the event are critical for their longevity and long-term healing of the heart’s tissue. Now researchers at Northwestern University and University of California, San Diego (UC San Diego) have designed a minimally invasive platform to deliver a nanomaterial that turns the body’s inflammatory response into a signal to heal rather than a means of scarring following a heart attack. Tissue engineering strategies to replace or supplement the extracellular matrix that degrades following a heart attack are not new, but most promising hydrogels cannot be delivered to the heart using minimally invasive catheter delivery because they clog the tube. The Northwestern-UC San Diego team has demonstrated a novel way to deliver a bioactivated, biodegradable, regenerative substance through a noninvasive catheter without clogging. The research, which was conducted in vivo in a rat model, was published recently in the journal … [Read more...] about Nanomaterial Helps Heal Damage after a Heart Attack

The rates of heart attacks are declining overall in the U.S. — but not among all groups of Americans. According to a new study, heart attack rates are increasing in what may seem like an unlikely group: adults in their 20s and 30s. What's more, despite their relatively young age, 20- and 30-somethings have the same rate of bad outcomes after a heart attack — including death — as those who are about 10 years older, the study found. "It used to be incredibly rare to see anyone under age 40 come in with a heart attack — and some of these people are now in their 20s and early 30s," senior study author Dr. Ron Blankstein, a preventive cardiologist at Brigham and Women's Hospital in Boston, said in a statement. "Based on what we are seeing, it seems that we are moving in the wrong direction." The study will be presented March 17 at the American College of Cardiology's annual scientific sessions meeting in New Orleans, and the findings have not yet been published in … [Read more...] about Why Are More Young People Having Heart Attacks?
