Slowing the racing heart
Researchers at the University of Illinois at Chicago explain in the May 11 issue of Circulation Research how an enzyme acts on the heart's pacemaker to slow the rapid beating of the heart's "fight-or-flight" reaction to adrenaline. view more (2007-05-14)
Engineered heart tissue offers insights into irregular heartbeats, defibrillator failure
Engineers who have induced heart cells in culture to mimic the properties of the heart have used the tissue to gain new insight into the mechanisms that spawn irregular heart rhythms. view more (2006-02-06)
Progress being made in exploring potential use of stem cells to treat heart disease
Scientists are making headway in exploring the potential future use of stem cells to treat heart disease, according to a review article in the current issue of Nature (June 29, 2006). view more (2006-06-29)
Consumption of fish oil does not appear to protect against abnormal heart rhythms
Patients with an implantable cardioverter defibrillator did not have a significantly lower risk of serious abnormal heart rhythms or death by consuming fish oil supplements, which had been thought to have a protective effect. view more (2006-06-14)
UC Davis researchers move biotechnology closer to replacing electronic pacemakers
UC Davis researchers have successfully used a custom designed protein and gene delivery system to restore normal heart rhythms in pigs with electronic pacemakers, reducing their dependence on implanted devices. view more (2006-08-23)
Patients with severe sleep-disordered breathing have high odds of abnormal heart rhythms
Patients with severe sleep-disordered breathing are two to four times more likely to experience complex, abnormal heart rhythms while sleeping than individuals without the problem, according to the Sleep Heart Health Study (SHHS). view more (2006-04-14)
Test identifies best candidates for implanted cardiac defibrillator, screens out those not helped
Last year, about 170,000 people in North America had devices surgically implanted to stop potentially fatal arrhythmias. view more (2006-01-30)
Medication reduces risk of heart irregularities after cardiac surgery
Use of the medication amiodarone is associated with one-half the incidence of atrial tachyarrhythmias (rapid, abnormal heart beat) following cardiac surgery, according to a study in the December 28 issue of JAMA. view more (2005-12-29)
Study finds implantable defibrillators as effective in women as in men
Women who have had a heart attack get as much survival benefit as men from implanted cardioverter defibrillators (ICDs), devices designed to monitor the heart's pumping rhythm and shock it back to normal when needed, according to a study published in the December edition of the Journal of Cardiovascular Electrophysiology. view more (2005-12-23)
Routine ECGs for newborns would identify life-threatening heart condition
Italian heart specialists are calling on health care providers throughout Europe to give urgent consideration to introducing ECG screening for all babies at around three to four weeks of age to pick up a life-threatening genetic condition called long QT syndrome. view more (2006-07-13)
Fish oil prevents potentially deadly decline in heart rate variability
A two-gram fish oil supplement given daily to elderly persons prevented a decline in heart rate variability caused by tiny, dangerous airborne pollutant particles. view more (2005-12-16)
After cardiac arrest, children fare better than adults, landmark study shows
Children are more likely to survive in-hospital cardiac arrests than adults and with appropriate cardiopulmonary resuscitation (CPR), the survival rates for both children and adults are higher than previously thought. view more (2006-01-05)
Researchers now able to look deep into heart to view triggers of a heart's beat
Being able to witness the precise events that form the heart's orchestral rhythm or the rat-a-tat-tat of irregular heartbeats could enable researchers to better understand the underlying causes of arrhythmias and sudden cardiac death. view more (2006-04-18)
New approach for genetic screening for syndrome linked to cardiac irregularities and sudden death
Italian researchers have developed a novel approach for genetic screening for long QT syndrome (LQTS), an inherited disease that predisposes young individuals to cardiac arrhythmias and sudden death. view more (2005-12-21)
Gatekeeping: Penn researchers find new way to open ion channels in cell membranes
Using an enzyme found in the venom of the brown recluse spider, researchers at the University of Pennsylvania School of Medicine have discovered a new way to open molecular pores, called ion channels, in the membrane of cells. view more (2006-07-18)
Heart rhythm genes possible factors in SIDS
Nearly 10 percent of sudden infant death syndrome (SIDS) victims have mutations or variations in genes associated with potentially lethal heart rhythms (arrhythmias), according to two newly published studies involving Vanderbilt researchers. view more (2007-01-16)
Air pollution damages more than lungs: Heart and blood vessels suffer too
As athletes from around the world compete in the Beijing Olympics, many are on alert for respiratory problems caused by air pollution. They should also be concerned about its toxic effects on the heart and cardiovascular system, mounting research shows. view more (2008-08-14)
Medication plus beta-blocker helps prevent shocks from implantable cardioverter defibrillator
Use of the medication amiodarone in combination with a beta-blocker is effective in preventing shocks that can occur from an implantable cardioverter defibrillator. view more (2006-01-11)
Largest study of in-hospital cardiac arrest suggests how to improve outcomes for children and adults
Children survive in-hospital cardiac arrests more frequently than adults, cardiopulmonary resuscitation (CPR) may improve outcomes for both groups, and better knowledge of the underlying cause of a cardiac arrest may increase the chances of helping a patient survive it. view more (2006-01-04)
JAMA study provides clues to cause of sudden cardiac death in teens
Fainting during childhood, and whether a teen is going through the male or female changes of puberty, are among the factors that predict whether a genetic defect will suddenly stop the teen's heartbeat, according to a study published today in the Journal of the American Medical Association (JAMA). view more (2006-09-13)
