heart failure

Researchers learned how IGFBP7, a senescence signaling protein and biomarker, promotes cardiac remodeling and cellular aging.

Primates receiving heart transplants from genetically engineered pigs have survived more than six months, a new study reveals.

Without knowing the cells’ mechanism of action, researchers question the best way to administer them to patients.

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

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.

The sinoatrial node is home to multiple pacemakers that keep the heart beating if the main one falters.

While the heart cells normally burn fatty acids, when things go wrong ketones become the preferred fuel source.

In failing hearts, cardiomyocytes change their fuel preference.

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

Texas Heart Institute heart surgeon Bud Frazier is a pioneer of heart transplant technologies.

A report reveals that using bone marrow stem cells to treat heart disease is less promising than a decade of research has let on.

Inhibiting a small regulatory RNA appears to improve cardiac function in mice with surgically induced heart problems.

A flexible, sensor-loaded membrane that fits snugly around the heart provides high-resolution monitoring of multiple cardiac health markers.

Disgraced stem-cell researcher Hisashi Moriguchi has published three new papers in BMJ Case Reports, including a rehashing of a retracted 2012 paper.

A molecule found only in the blood of young mice dramatically reverses thickening and stiffening of the heart muscle in old mice.

From cardiovascular problems to neurological disorders, a plethora of new medical devices are reducing the need for surgery and improving the quality and safety of healthcare.

In guinea pigs, the insertion of a single gene can transform ordinary heart cells into pacemaker cells that regulate cardiac rhythm.

Despite abundant evidence supporting their ability to help prevent and treat cardiovascular disease, the therapeutic effectiveness of fish oil–derived fatty acids remains controversial.
