Experts have a decent grasp on how COVID-19 impacts cardiovascular health in the near term. The implications of long COVID, however, remain mysterious.

The procedure, performed last Friday, is a milestone in a long effort to boost the number of organs available for safe transplantation.

Specialized immune cells generated in vivo reduce cardiac scar tissue in mice, a new study shows.

Researchers link a missense mutation in the B4GALT1 gene to lower levels of LDL cholesterol and the blood clotting factor fibrinogen.

Health authorities in both countries announced that people under certain age cutoffs are now ineligible for the Spikevax COVID-19 shot due to its association with heart inflammation.

A chronically stressed amygdala can prime the heart to overreact to acute stress events, a new study shows.

Two of the implanted valves lasted a full year as the animals matured into adult sheep, demonstrating that it might be possible to treat children with valve replacements that grow along with them.

The multifarious nature of the damage means treatments for cardiac issues during infection will require tailored approaches.

Images of the players’ hearts showed signs of inflammation consistent with myocarditis, a rare but potentially fatal condition.

There is little evidence that antihypertensive drugs worsen COVID-19, and scientists are instead exploring the idea that such medications—or their downstream effects—may actually alleviate symptoms.

A bioengineered heart made of pig and synthetic tissues beats like the real thing.

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.

Slowing to just two beats per minute, the animals’ heart rate shows how they survive plunging far below the ocean’s surface to eat.

A clinical trial is underway to see if suspended animation, in which the body is cooled to 10–15 °Celsius, could slow patients’ decline and give doctors time to operate.

Scientists show the approach can kill cells that cause hardening of heart tissue in mice.

A case study of a family demonstrates that different genetic mutations from the two parents cause severe heart disease symptoms in the children.
