Could an App Ease the Stress of Managing Heart Failure?

A heart failure diagnosis can be an unsettling experience. Add in a deluge of new medication regimens and lifestyle changes to implement, and the entire episode can begin to feel very overwhelming for a heart failure patient. A new smartphone app from Jana Care, called Heart Habits, was created in the hopes of streamlining cardiac […]

Mass General Researchers Investigate the ‘Big Eaters’ of the Immune System: #MacrophageMonday

Macrophages serve a vital function in the body’s immune system— these white blood cells are in charge of engulfing pathogens, foreign materials and dead cells. Two new studies from Massachusetts General Hospital researchers have identified two unexpected roles that macrophages play in the body. In the heart, macrophages play a beneficial role, helping heart muscle […]

Mass General Scientists are Growing New Hearts in the Cells of Old Ones

(From an article in Atlas Obscura by Sarah Laskow) For decades now, there’s been an image of human regeneration being a few cells dividing in a petri dish, hopefully growing into a shiny new organ. But the truth is that scientists’ work is a bit more macabre. To make a new organ, it helps to be working from a […]

Scientists Grow Functional Heart Muscle

A team of researchers led by Dr. Harald Ott of the Massachusetts General Hospital Center for Regenerative Medicine have grown functional heart tissue using donated hearts stripped of their cells. This breakthrough could allow tissue patches grown from a patient’s own cells to replace cardiac tissue damaged during a heart attack.   LEARN MORE

Bariatric Surgery May Reduce Life-Threatening Heart Failure Exacerbation in Obese Patients

“We found that bariatric surgery – the most effective way to achieve substantial and sustained weight loss – was associated with a 40 percent reduction in emergency department visits and hospitalizations for heart failure exacerbation,” says Yuichi Shimada, MD, MPH, of the Mass General Cardiology Division, the lead and corresponding author of the report. “These findings are important because, while […]

The Guide: Have a Heart

At Mass General’s Ott Laboratory for Organ Engineering and Regeneration, a small army of postdocs is drawing on the tenets of tissue engineering and stem cell science to develop “bioartificial” organs and limbs for patients in need. While it sounds like something cooked up in the pages of a Michael Crichton thriller, this novel approach has the potential to […]

Wakefield Researcher ‘Seals’ the deal in Antarctica

Massachusetts General Hospital researcher Emmanual Buys, PhD, is part of a collaborative research team that has been working in Antarctica to study the Weddell seal, a mammal that can remain under water for longer than 70 minutes at a depth of 500 meters. Buys and his team are taking tissue samples from seals to learn […]
