A heart damaged by heart attack is usually broken, at least partially, for good. The injury causes excessive scar tissue to form, and this plays a role in permanently keeping heart muscle from working at full capacity.
Now researchers have identified a key molecule involved in controlling excessive scar tissue formation in mice following a heart [...]

Anyone will tell you that stress is bad for the heart. Many people also know about the toxic effects of anxiety and depression. But how exactly do these negative emotions cripple the cardiovascular system—and what can be done about it?
New research published in the December 16/23, 2008, issue of the Journal of the American College [...]

A new study shows that the equivalent of one dose of caffeine (just two cups of coffee) ingested during pregnancy may be enough to affect fetal heart development and then reduce heart function over the entire lifespan of the child. In addition, the researchers also found that this relatively minimal amount of exposure may lead [...]

An implantable hemodynamic monitor (IHM) may help to guide medical treatment in a large subgroup of patients with heart failure—those with diastolic heart failure (DHF), reports a study in the December Journal of Cardiac Failure.
Led by Michael R. Zile, M.D., of Medical University of South Carolina, Charleston, the researchers analyzed data on DHF patients enrolled [...]

Researchers at the University of Maryland School of Medicine in Baltimore have discovered a novel gene mutation among the Old Order Amish population that significantly reduces the level of triglycerides in the blood and appears to help prevent cardiovascular disease.
"We found that about 5 percent of the Amish have a gene mutation that speeds up [...]

A medication used for high blood pressure does not improve a common form of heart failure, according to new results from a large, international study.
The study, which included researchers at Wake Forest University Baptist Medical Center in key leadership positions, appears in the New England Journal of Medicine December 4.
The findings are disappointing to researchers, [...]

Up until today scientists assumed that the adult heart is unable to regenerate. Now, researchers and cardiologists from the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and the Charité – Universitätsmedizin Berlin (Germany) have been able to show that this dogma no longer holds true.
Dr. Laura Zelarayán and Assistant Professor Dr. Martin W. Bergmann [...]

People who have been diagnosed with panic attacks or panic disorder have a greater risk of subsequently developing heart disease or suffering a heart attack than the normal population, with higher rates occurring in younger people, according to new research.
The study found that people who were younger than 50 when first diagnosed had a significantly [...]

A new study shows that atrial fibrillation–the most common form of sustained heart arrhythmia–can be caused in an unexpected way. Researchers report in the December 12th issue of the journal Cell, the first evidence that a rare and particularly severe form of the disease stems from a gene involved in shuttling other molecules in and [...]
