Size matters: Obesity leading risk factor of left atrial enlargement during aging
Aside from aging itself, obesity appears to be the most powerful predictor of left atrial enlargement (LAE), upping one's risk of atrial fibrillation (the most common type of arrhythmia), stroke and death. view more (2009-11-10)
New methods found useful for diagnosing myocarditis
Myocarditis is an important, and often unrecognized cause of dilated cardiomyopathy (DCM). Several new diagnostic methods, such as cardiac magnetic resonance imaging (MRI), are useful for diagnosing myocarditis, according to a study published in the November 2009 issue of Mayo Clinic Proceedings. view more (2009-11-04)
Women with diabetes at increased risk for irregular heart rhythm
Diabetes increases by 26 percent the likelihood that women will develop atrial fibrillation (AF), a potentially dangerous irregular heart rhythm that can lead to stroke, heart failure, and chronic fatigue. view more (2009-09-28)
Prostate cancer patients on hormone therapy at increased risk for various heart diseases
New research has found that hormone therapy used to treat men with advanced prostate cancer is associated with an increased chance of developing various heart problems. Some choices of therapy appear, however, to be less risky than others. view more (2009-09-22)
Atrial fibrillation: Drugs or ablation?
Atrial fibrillation ablation is one of the fastest growing techniques in cardiology and due to the very high number of patients that might be candidates to this procedure, a significant number of resources will have to be devoted to it to be able to treat them in the following years. view more (2009-09-01)
High calcium level in arteries may signal serious heart attack risk

Older men with breathing problems during sleep more likely to have irregular heartbeats
Increasingly severe sleep-related breathing disorders in older men appear to be associated with a greater risk of abnormal heart rhythms (arrhythmias). view more (2009-06-23)
Enzyme doesn't act alone in atrial fibrillation
An overactive enzyme is behind a leaky calcium channel that plays a role in the development of atrial fibrillation, which is the most common cardiac arrhythmia that is responsible for a third of all strokes. view more (2009-06-18)
Immune cells ameliorate hypertension-induced cardiac damage in mice

Natural hormone offers hope for treatment of the metabolic syndrome
Angiotensin 1-7, a hormone in the body that has cardiovascular benefits, improves the metabolic syndrome in rats, according to a new study. The results will be presented Wednesday at The Endocrine Society's 91st Annual Meeting in Washington, D.C. view more (2009-06-10)
Expert consensus on catheter ablation of ventricular arrhythmias
A call to action for more research to be undertaken into catheter ablation in the field of ventricular arrhythmia (VA) has been issued in a joint consensus document from the European Heart Rhythm Association (EHRA) a registered branch of the European Society of Cardiology (ESC) and the US Heart Rhythm Society (HRS). view more (2009-05-14)
Study examines novel PFO closure system
A new device designed to close a common heart defect known as a patent foramen ovale (PFO) is safe and effective at 90-days follow up, according to a new study released today at the Society for Cardiovascular Angiography and Interventions (SCAI) 32nd Annual Scientific Sessions in Las Vegas. view more (2009-05-11)
Global monsoon drives long-term carbon cycles in the ocean
Monsoon is a global system, and many arrays of evidence indicate that it drives long-term cyclicity of the carbon reservoir in the global ocean. view more (2009-05-08)
Arrythmia associated with heart attacks linked to higher risk of death
Heart attack patients who develop serious arrhythmia in connection with procedures to open blocked arteries face a significantly higher risk of death for several months after the procedure, when compared to similar patients who do not develop such complications, according to new research from Duke University Medical Center. view more (2009-05-06)
Valve implantation on the beating heart
Transcatheter valve implantation is a newly developed technique for the curative treatment of high-grade aortic stenosis. It is likely to be of benefit especially to elderly, multimorbid patients for whom the risk of open heart surgery would be too great. view more (2009-04-21)

Targeted drug therapy prevents exercise-induced arrhythmias
A 12-year-old Dutch boy - bedridden for three years because of an inherited cardiac arrhythmia syndrome - can now join his friends on the soccer field thanks to a discovery made by Vanderbilt University Medical Center researchers. view more (2009-03-30)
Feeling down and out could break your heart, literally
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). view more (2009-03-10)
Kidney disease increases the risk of stroke in patients
Chronic kidney disease increases the risk of stroke in patients with atrial fibrillation (AF), the most common type of heart arrhythmia, according to a new study by Kaiser Permanente researchers in the current online issue of Circulation. view more (2009-03-05)
