sudden cardiac death
To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins.
Targeted postmortem testing to identify genetic mutations associated with sudden unexplained death (SUD) is an effective and less expensive way to determine risk to relatives than comprehensive cardiac testing of first degree relatives, according to research presented at the American Heart Association's Scientific Sessions 2009.
Postmortem genetic testing can identify mutations that cause c
A multi-national research team has discovered that two genetic factors converge to increase the risk of sudden cardiac death.
New Orleans, LA -- Research led by Hernan A. Bazan, MD, Assistant Professor of Surgery, Section of Vascular Surgery, at LSU Health Sciences Center New Orleans School of Medicine, has found that unstable carotid artery plaques -- those in danger of rupturing and leading to a stroke -- contain more inflammation and significantly less omega-3 fatty acids than asymptomatic plaques.
NEW YORK (September 20, 2009) -- Genes previously known to be essential to the coordinated, rhythmic electrical activity of cardiac muscle -- a healthy heartbeat -- have now also been found to play a key role in thyroid hormone (TH) biosynthesis, according to Weill Cornell Medical College researchers.
Implantable cardioverter-defibrillators do not appear to be associated with a reduced risk of death in women with advanced heart failure, according to a meta-analysis of previously published research in the September 14 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Patients who had a cardiac resynchronization device combined with a defibrillator (CRT-D) implanted had a 34 percent reduction in their risk of death or heart failure when compared to patients receiving only an implanted cardiac defibrillator (ICD), according to a landmark study published online today in the New England Journal of Medicine and presented today at the European Society of C
Barcelona, Spain, 1 September: The goals of the PreSCD II (Prevention of Sudden Cardiac Death II) registry are to collect recent data on patients with high risk for sudden cardiac death after a heart attack and to describe their prognosis in relation to initial left ventricular ejection fraction (LVEF) as the primary risk marker.
NEW YORK (Aug. 27, 2009) -- QRS duration (QRSd) is one of several measures of heart function recorded during a routine electrocardiogram (ECG). It is a composite of waves showing the length of time it takes for an electrical signal to get all the way through the pumping chambers of the heart.
There is mounting evidence that omega-3 fatty acids from fish or fish oil supplements not only help prevent cardiovascular diseases in healthy individuals, but also reduce the incidence of cardiac events and mortality in patients with existing heart disease.
OAK BROOK, Ill. -- Researchers may be able to predict future severe cardiac events in patients with known, stable coronary artery disease (CAD) using coronary calcium scoring, according to a study published in the online edition of Radiology.
The chemical bisphenol A, commonly found in many plastic household items, has been linked to yet another health problem in animals -- an increased frequency of arrhythmias, or heartbeat irregularities, a new study found. The results, seen only in females, will be presented Saturday at The Endocrine Society's 91st Annual Meeting in Washington, D.C.
Vienna, Austria: Relatives of a young person who dies suddenly should always be referred for cardiological and genetic examination in order to identify if they too are at risk of sudden death, a scientist told the annual conference of the European Society of Human Genetics today (Tuesday 26 May). Dr.
NEW YORK (May 5, 2009) - A common misconception about arterial plaque is that it inevitably leads to a heart attack or a stroke. New research at Columbia University Medical Center, however, sheds light on why so few plaques in any given individual actually cause a problem.
Screening for coronary artery disease in patients with type 2 diabetes did not result in a significant reduction in the rate of heart attacks or cardiac death compared to patients who were not screened, according to a study in the April 15 issue of JAMA, a theme issue on diabetes.
