Preventive placement of ICDs improves survival in patients with less severe heart failure

An examination of the benefit of preventive placement of implantable cardioverter-defibrillators (ICDs) in patients with a less severe level of heart failure, a group not well represented in clinical trials, finds significantly better survival at three years than that of similar patients with no ICD, according to a study in the June 4 issue of JAMA.

Two international research studies, both led by investigators affiliated with Massachusetts General Hospital (MGH) and the Broad Institute of MIT and Harvard, have uncovered new information about genes that may increase the risk of serious cardiac arrhythmias. [More]
Implantable cardioverter defibrillators improve survival among heart failure patients

Implantable cardioverter defibrillators improve survival among heart failure patients

Implantable cardioverter defibrillators (ICDs) are associated with improved survival among heart failure patients whose left ventricles only pump 30 to 35 percent of blood out of the heart with each contraction, according to a study from the Duke Clinical Research Institute. [More]
Genetic variant linked to sudden cardiac death leads to protein overproduction in heart cells

Genetic variant linked to sudden cardiac death leads to protein overproduction in heart cells

A genetic variant linked to sudden cardiac death leads to protein overproduction in heart cells, Johns Hopkins scientists report. Unlike many known disease-linked variants, this one lies not in a gene but in so-called noncoding DNA, a growing focus of disease research. [More]
Loyola offers new type of implantable defibrillator that prevents sudden cardiac death

Loyola offers new type of implantable defibrillator that prevents sudden cardiac death

Loyola University Medical Center has begun offering patients a new type of implantable defibrillator that prevents sudden cardiac death with an electric shock to the heart. [More]
Penn study clarifies action of potential new class of pain relievers that may benefit and not hurt heart

Penn study clarifies action of potential new class of pain relievers that may benefit and not hurt heart

Nonsteroidal antinflamatory drugs (NSAIDs) that block an enzyme called COX-2 relieve pain and inflammation but can cause heart attacks, stroke, heart failure, and even sudden cardiac death. [More]

Boston Scientific to launch of S-ICD System into parts of Asia

Boston Scientific Corporation (NYSE: BSX) has expanded the launch of its S-ICD System into parts of Asia. The first implant of the S-ICD System in Asia was performed in Hong Kong by Prof. Hung Fat Tse, Professor of Cardiovascular Medicine, The University of Hong Kong and Department of Medicine, Queen Mary Hospital in Pokfulam, Hong Kong, under the proctorship of Dr. Martin Stiles, Director of Electrophysiology, Waikato Hospital in Hamilton, New Zealand.

Researcher finds simple blood test that predicts person's risk for sudden cardiac death

Researcher finds simple blood test that predicts person's risk for sudden cardiac death

A researcher at the Cardiovascular Institute (CVI) at Rhode Island, The Miriam and Newport hospitals has found that a simple blood test can predict a person's risk for sudden cardiac death, enabling physicians to more quickly and accurately assess a patient's need for an implantable cardiac defibrillator (ICD).

ZS Pharma starts patient enrollment in ZS-9 Phase 3 trial for treatment of hyperkalemia

ZS Pharma, a specialty pharmaceutical company developing novel treatments for kidney, cardiovascular and liver disorders, today announced that it has begun enrolling patients in ZS004, its second Phase 3 clinical trial of ZS-9, a novel investigational treatment for hyperkalemia. [More]
Scientists explore link between SCN10A and cardiac arrhythmia risk

Scientists explore link between SCN10A and cardiac arrhythmia risk

Although genome-wide association studies have linked DNA variants in the gene SCN10A with increased risk for cardiac arrhythmia, efforts to determine the gene's direct influence on the heart's electrical activity have been unproductive. Now, scientists from the University of Chicago have discovered that these SCN10A variants regulate the function of a different gene, SCN5A, which appears to be the primary gene responsible for cardiac arrhythmia risk.

Researchers find new drug compound that treats laboratory mice with congenital heart disease

Researchers find new drug compound that treats laboratory mice with congenital heart disease

Congenital heart disease is the most common form of birth defect, affecting one out of every 125 babies, according to the National Institutes of Health. Researchers from the University of Missouri recently found success using a drug to treat laboratory mice with one form of congenital heart disease, hypertrophic cardiomyopathy - a weakening of the heart caused by abnormally thick muscle.
