Scientists at the Gladstone Institute of Cardiovascular Disease (GICD) have traced the evolution of the four-chambered human heart to a common genetic factor linked to the development of hearts in turtles and other reptiles.

A new study by British scientists indicates that healthy people who may be taking a daily dose of aspirin as a preventative against heart disease may be doing themselves more harm than good.

In 1995 British doctors implanted a donor heart directly onto Hannah Clark's failing one, rather than risk a heart - lung transplant. Now, after 10 years with 2 hearts, and the donor heart removed, her original heart has healed.

Using zebrafish, researchers at the University of Pittsburgh have identified and described an enzyme inhibitor that allows them to increase the number of cardiac progenitor cells and therefore influence the size of the developing heart. The findings are described in the advance online version of Nature Chemical Biology.

Brian Mandeville, a 6-foot-6, 255-pound tight end, who caught 63 passes for 863 yards and seven touchdowns in three seasons with the Northeastern University Huskies, has been told to retire by NFL combine doctors.

Earlier this year John McCain was forced to remove a YouTube video because it used the song "Can't Take My Eyes Off of You" by Frankie Valli and the Four Seasons, without permission.

A new study conducted by US researchers has proved that cells taken from human bone marrow, blood and umbilical cords can grow into functioning blood vessels in mice provided the coaxing is right.

A person's heart rate can reveal a lot about how they make decisions when feeling stressed, a Queensland University of Technology academic says.

Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells.

Atherosclerosis is what our parents and grandparents used to call hardening of the arteries. The bad news about atherosclerosis: It leads to tens of thousands of deaths every year in the U.S. The good news: You can prevent it.

For the first time researchers are beginning to understand exactly how various forms of exercise impact the heart. Massachusetts General Hospital (MGH) investigators, in collaboration with the Harvard University Health Services, have found that 90 days of vigorous athletic training produces significant changes in cardiac structure and function and that the type of change varies with the type of exercise performed.
