People living in the hottest places on Earth could be up to three times as likely to die from a heart-related cause, according to a newly-published study. Global warming due to climate change has the potential to further worsen the heat-stress problem,… Continue reading Risk of heart-related death may triple in extreme heat environments
For some children born with congenital heart disease, prosthetic valves that maintain a healthy flow of blood are a harsh reality of their young lives. This not only requires open heart surgery to implant the device initially, but repeated high-risk procedures to replace them every few years as their body grows. Researchers at Boston Children’s Hospital have been working towards more of a one-size-fits all solution, and have come up with a design they say works at a variety of diameters, and can be adjusted as needed without the need for invasive surgeries down the track.

After a heart attack has occurred, some of the beating cardiac tissue ends up being replaced with non-beating scar tissue – this permanently compromises the function of the heart. A new patch, however, is designed to help.Continue ReadingCategory: Medi… Continue reading Conductive polymer patch designed to repair damaged hearts
Atherosclerosis is a disease where fatty plaques build up in the arteries, increasing a person’s risk of suffering a heart attack or stroke. But now, researchers at Oxford University have found a protein that appears to trigger this cascade of events, … Continue reading Problem protein could be new drug target for preventing heart attacks
Fair warning for the squeamish: some versions of [Will Cogley]’s animatronic heart are realistic enough that you might not want to watch the video below. That’d be a shame though, because he really put a lot of effort into the build, and the results have a lot to teach about …read more
A beating heart relies on a healthy circuitry of electrical signals to maintain a steady rhythm, and when that system breaks down it can lead to grave consequences. Pacemakers and medications can be enlisted to correct these kinds of irregula… Continue reading Conductive carbon fibers bridge busted electrical circuits in the hearts of mice
Considering how important an organ it is, it’s a shame that the heart is so bad at repairing itself. One heart attack is rarely the end of the problem, as scarring prevents healing and often leads to further attacks. Stem cells are an emergin… Continue reading Giving stem cells some support helps heal damaged hearts
While in its early stages, bioprinting of human tissue is an emerging technology that is opening up some exciting possibilities, including the potential to one day 3D print entire human organs. This scientific objective has now grown a little… Continue reading 3D bioprinting breakthrough leads to full-scale, functioning heart parts
Cardiovascular diseases are the number one killer in the world – and it turns out we might have a two million year old ancestor to blame. Researchers at the University of California San Diego (UCSD) have pinpointed a single gene that ancient … Continue reading A single gene mutation 2 million years ago may have made humans prone to heart disease
As important and durable as it is, the heart has quite a lot of difficulty in repairing itself after sustaining damage. But now, researchers from the University of Calgary have found a previously unidentified cell population in the fluid that… Continue reading Newly-discovered cells help patch up scarred hearts
