Sudden Cardiac Death News and Research

RSS

The term sudden cardiac death refers to natural death from cardiac causes, heralded by abrupt loss of consciousness within one hour of the onset of acute symptoms.

Smokers more likely to receive jolt from defibrillators

If some patients with heart disease don't take their doctor's advice to quit smoking, they are probably going to get "shocking" reminders.

New method allows heart beat triggers to be viewed and better understood

Researchers have developed unique chemical dyes that have made it possible to see what the naked eye has never seen before: action potentials, or voltage changes, of cardiac cells - including those deep inside the heart, which trigger and determine the pace of heartbeats.

Benefit of fish oils under question

In a turn up for the books, experts are now saying that contrary to the widely held belief that the omega 3 fats found in oily fish help prevent heart disease, this has not been proven.

Study identifies patients at risk for sudden cardiac death

Researchers have found a more accurate way to tell which children and teenagers are likely to be among the thousand or so who suddenly die each year in the United States from genetic heart conditions that cause arrhythmia

Implantable defibrillators benefit women as much as men after heart attack

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.

Study to look for links between the nervous system and fatal heart rhythm

Finding out why seemingly healthy people experience ventricular fibrillation, a fatal irregular heart rhythm, could eventually lead to better methods of early detection, according to a Medical College of Georgia researcher.

Carvedilol, a cardiovascular drug, may improve heart failure and help prevent sudden death

Research shows that Carvedilol, a cardiovascular drug, could be useful in reducing cardiac death in high risk patients with prior myocardial infarction and/or heart failure and also in reducing the incidence and/or preventing the occurrence of atrial fibrillation in a number of clinical situations.

MRI measurements of scar tissue accurately predict the risk of arrhythmia-related sudden death

Using magnetic resonance imaging (MRI) scans of the heart wall, researchers at Johns Hopkins have found that people whose muscle wall thickness contained more than 25 percent scar tissue were approximately nine times more likely to test positive for a fast and dangerous heart rhythm known as ventricular arrhythmia.

Defibrillator implantations performed by physicians with low volume are more likely to have adverse outcomes

As the implantation of cardioverter-defibrillator devices to prevent sudden cardiac death becomes increasingly popular, patients are likely to get the best results when they are treated by physicians who perform the procedures frequently, according to a new study in the Oct. 18, 2005, issue of the Journal of the American College of Cardiology.

Cost-effectiveness of potentially life-saving implantable cardioverter defibrillators (ICD) is an important public health issue

The use of implanted defibrillators that keep the heart beating in proper electrical rhythm to prevent cardiac arrest appears to be cost-effective for those patients who receive a significant mortality reduction, according to researchers from Duke Clinical Research Institute (DCRI), Stanford University and the VA Palo Alto Health Care System, Calif. They analyzed eight clinical trials of the devices to arrive at their conclusion.

Benefits of starting CHF treatment with beta-blocker, bisoprolol

Initiating treatment with the selective beta-blocker, bisoprolol, is as effective and well tolerated as beginning treatment with an ACE inhibitor. However, starting treatment with bisoprolol may reduce the risk of death especially in the first year of treatment.

Guidant receives FDA approval to re-enter heart failure market

Guidant Corporation has announced U.S. Food and Drug Administration (FDA) approval to re-launch its CONTAK RENEWAL 3 family of cardiac resynchronization therapy (CRT) defibrillators in the United States.

Innovation that helps locate and treat life-threatening heart arrhythmias

The Research Foundation of SUNY, which supports the advancement of education, research and discovery at the State University of New York, today announced it signed a licensing agreement with Biosense Webster Inc. for the rights to an Upstate Medical University innovation that helps locate and treat life-threatening heart arrhythmias.

Stem cell therapy can be used effectively to treat heart attacks, or myocardial infarction, in pigs

In just two months, stem cells harvested from another pig's bone marrow and injected into the animal's damaged heart restored heart function and repaired damaged heart muscle by 50 percent to 75 percent.

Fish oil does not lower risk of serious heart rhythm abnormalities for patients with implantable defibrillators

Even though previous research has shown that fatty acids from fish oil reduce the risk of sudden cardiac death, patients with implantable defibrillators who took fish oil supplements did not see a reduction in serious heart rhythm abnormalities, according to a study in the June 15 issue of JAMA: The Journal of the American Medical Association.

Short term high pollution concentrations linked to dangerous heart arrhythmias

Researchers from the Harvard School of Public Health and colleagues from Boston area medical institutions have linked short term high pollution concentrations with an increased incidence of irregular and very dangerous heart arrhythmias among a group of cardiac patients from the greater Boston area who had implanted cardioverter defibrillators (ICD).

Increased risk of sudden cardiac death from some non-cardiac drugs

Non-cardiac drugs that interfere with the electrical activity controlling the heartbeat are associated with a three-fold risk of sudden cardiac death, according to Dutch research published (Wednesday 11 May) in Europe's leading cardiology journal, the European Heart Journal.

Fickle enzyme helps protect, but also can promote heart failure

Enzymes that make the gas nitric oxide (NO) not only protect the heart from damage due to high blood pressure or a heart attack, but also promote heart failure through overgrowth and enlargement of the muscle tissue, say animal researchers at Johns Hopkins.

Fish and soy oil help keep hearts healthy

Researchers say that older people who take a daily fish or soy oil supplement can reduce their risk of developing irregular heart rhythm or sudden cardiac death.
