Research in mice and humans points to oxidative stress and inflammation as likely drivers of noise-induced health effects such as hypertension and heart disease.

Sound from cars, aircraft, trains, and other man-made machines is more than just annoying. It increases the risk of cardiovascular disease.

Mice that experienced heart attacks underwent a large-scale shift in their immune systems that allowed cancer to flourish, perhaps explaining the observation in patients.

A growth factor treatment helps improve cardiac functioning after heart attack in pigs.

To advance the possibility of off-the-shelf cardiac cell therapies, scientists devise an engineered cardiac stem cell that avoids stimulating a detrimental immune attack.

A study in mice reveals that stem cell transplants, currently in clinical trials, may not actually require the cells.

The pharmaceutical firm is buying The Medicines Company, which recently devoted its efforts into developing the cholesterol-lowering medication.

Mutating a gene called CMAH in mice so it’s nonfunctional, as in humans, upped the animals’ chances of developing heart disease, a study finds.

Maps of diving cells before and after heart attacks in mice offer additional evidence against the existence of cardiac stem cells.

Among 11 infants treated to date, most survived and their heart function improved.

The organ’s blood-pumping capacity improved with the infusion of cells, a study shows.

Cardiologists have found a way to cool the human heart in a localized way to help reduce muscle damage from heart attacks. 

Research in human patients and mice reveals the role of the circadian clock in the risk of heart damage at different times of day.

A failing heart is easily distinguished from a healthy one by numerous tell-tale signs, including its slender, stretched-out walls, increased size, and pooled blood clots.

Injecting photosynthetic microbes into oxygen-starved heart tissue can improve cardiac function in rodents. 

A cholesterol-lowering drug significantly cut the risk of heart attack and stroke in a recent study. But is it worth the steep cost?

After a heart attack, monkeys given induced pluripotent stem cell–derived cardiomyocytes show more regeneration in the organ, but with risks.

Is there room to improve upon the tried-and-true, decades-old technology of artificial hearts?
