Scientists have long thought that the cells that ultimately give rise to the heart all respond to the same cue before turning into the muscle tissue of this vital organ.

Cardiovascular diseases (CVD) are major contributors to morbidity and mortality worldwide. Several interacting environmental, biochemical, and genetic risk factors can increase disease susceptibility.

Studies have shown that exercise has a positive effect on mothers-to-be, and no detrimental impact on their developing offspring. A new study further extends the knowledge of research in this area and has found that not only do women benefit from exercise in pregnancy, but their fetuses do too.

A catheter-mounted device that acts like a clothespin to clip together the flaps of a leaky heart valve is not only reducing the abnormal backflow of blood from the left ventricle to the left atrium, it is helping to shrink the enlarged, overworked heart and relieving symptoms of fluid overload—all without open-chest surgery.

A Saint Louis University cardiologist called upon the U.S. Food and Drug Administration (FDA) on Monday to reconsider a strong warning it recently placed on a diagnostic tool, stating that the warning could prevent doctors from detecting life-threatening cardiac events.

CPR, also known as Cardio Pulmonary Resuscitation can mean life and death for a person. Here is the latest news on CPR: The American Heart Association says the CPR needs to be done only by hands and that people standing nearby can save a life of a person who needs emergency CPR.

Dutch medical researcher Christiaan Tji-Joong Gan has established that patients with a high blood pressure in the lungs die because the right ventricle is not capable of pumping blood against this pressure. Further, the right ventricle needs a longer rest phase between each pumping phase. Gan is the first Mosaic laureate to gain his doctorate.

Percutaneous coronary intervention (PCI) may be a reasonable alternative to bypass surgery in patients with blockages in the left main coronary artery, according to a study that found no significant difference in rates of survival when stents and bypass surgery were used to restore blood flow through this critically important artery.

Dr. Russo and her colleagues from the division of cardiovascular medicine at Penn will present research on disparities in treatment of women suffering atrial fibrillation, one of the most common abnormal heart rhythms.

In a comparison of anticoagulants and stents for use with angioplasty following a heart attack, the anticoagulants abciximab and tirofiban had similar outcomes for some cardiac measures within 90 minutes after the procedure, while patients who received stents that released the drug sirolimus had a lower risk of major adverse cardiac events within 8 months than patients who received uncoated stents, according to a JAMA study being released early online March 30.

When it comes to matters of the heart, many experts say that communication is the key to a healthy relationship. But a recent study out of Temple University’s School of Medicine finds that communication is the key to a healthy heart, as well.
