New test successfully identifies arrhythmogenic right ventricular cardiomyopathy

A study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has demonstrated that a new immunohistochemical test is reliable in diagnosing a dangerous arrhythmic heart disease known as arrhythmogenic right ventricular cardiomyopathy (ARVC.) Reported in the March 12 issue of The New England Journal of Medicine ( NEJM ), the new findings offer the possibility of a highly sensitive and specific means of identifying this life- threatening condition at an early stage, when it can be treated with by implanting a cardiac defibrillator.

Relationship between depressive symptoms and cardiac events

New data published in the March 17, 2009, issue of the Journal of the American College of Cardiology suggest that relatively healthy women with severe depression are at increased risk of cardiac events, including sudden cardiac death (SCD) and fatal coronary heart disease (CHD).

Advances in stem cell research

Scientists at The University of Texas Health Science Center at Houston are on the forefront of stem cell research, developing novel therapies designed to generate heart cells, repair traumatic lung injuries, grow new bone and stanch the spread of cancer cells.

An angry heart can lead to sudden death

Before flying off the handle the next time someone cuts you off in traffic, consider the latest research from Yale School of Medicine researchers that links changes brought on by anger or other strong emotions to future arrhythmias and sudden cardiac arrests, which are blamed for 400,000 deaths annually.

New understanding of how anger can ventricular arrhythmias

New research published in the March 3, 2009, issue of the Journal of the American College of Cardiology finds that anger-induced electrical changes in the heart can predict future arrhythmias in patients with implantable cardioverter-defibrillators (ICDs).

Rhythm abnormality of unknown origin strongly predicts sudden death risk in heart disease patients

Researchers conducting a large, ongoing study to improve detection and prevention of sudden cardiac death were surprised to discover that a specific heart rhythm abnormality – idiopathic QT interval prolongation – increased risk five-fold among patients with coronary artery disease.

Discovery could lead to novel arrhythmia treatments

Abnormal heart rhythms - arrhythmias - are killers. They strike without warning, causing sudden cardiac death, which accounts for about 10 percent of all deaths in the United States.

The worst luck in the world? The heart disease mutation carried by 60 million

Heart disease is the number one killer in the world and India carries more than its share of this burden. Moreover, the problem is set to rise: it is predicted that by 2010 India's population will suffer approximately 60% of the world's heart disease.

Candesartan shown to be safe new therapy for genetic heart disease

A new clinical trial suggests that long-term use of candesartan, a drug currently used to treat hypertension, may significantly reduce the symptoms of genetic heart disease.

New evidence shows that the heart beats to its own drummer

They've uncovered some of the molecular circuitry within the cardiovascular system itself that controls the daily rise and fall of blood pressure and heart rate. The findings might also explain why commonly used diabetes drugs come with cardiovascular benefits, according to the researchers.
