Breakthrough in unravelling the causes of sudden cardiac death in young people
Scientists at the Wales Heart Research Institute, Cardiff University have made a breakthrough in our understanding of the causes of sudden cardiac death (SCD) in young people. view more (2005-12-09)
AMIODARONE REDUCES RISK OF ATRIAL FIBRILATION AFTER OPEN-HEART SURGERY (p 830)
The drug amiodarone when taken orally in combination with ß-blockers is effective in preventing atrial fibrillation, conclude authors of a study in this week's issue of THE LANCET. Postoperative atrial fibrillation (AF - the most common form of sustained irregular heartbeat due to uncoordinated impulses in the small pumping chambers of the... view more... (2001-03-15)
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)
Johns Hopkins housing and testing only 256-slice CT scanner in North America
Johns Hopkins Medicine has installed for three months of initial safety and clinical testing a 256-slice computed tomography (CT) scanner, believed to be the world's most advanced CT imaging software and machinery. view more (2007-03-27)
Common bronchodilator linked to increased deaths
A common bronchodilator drug which has been used for more than a decade by patients with chronic obstructive pulmonary disease (COPD) has been linked to a one-third higher risk of cardiovascular-related deaths. view more (2008-09-16)
Mayo Clinic spearheads research to discover unsuspected gene for atrial fibrillation
Mayo Clinic researchers have found a gene mutation linked to one family's hereditary form of atrial fibrillation. Researchers hope this discovery will lead to better understanding of the disease and, eventually, better ways to predict, prevent and treat the heart rhythm problem. view more (2008-07-10)
Use of hydrocortisone reduces incidence of atrial fibrillation after cardiac surgery
Patients who receive corticosteroids after cardiac surgery have a significantly lower risk of atrial fibrillation in the days following the surgery. view more (2007-04-11)
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)
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)
Ventricular Regulation May Be Key to Preventing Heart Failure
A four-week study conducted on animals revealed that regulating ventricular rates and heart structure in models with irregular heart rhythms can inhibit chronic heart failure (CHF). view more (2004-11-18)
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)
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)
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)
Pediatric heart condition's origin, prevalence mirror adults
The mystery behind a commonly untreatable and undetected heart muscle disease in children is partially revealed for the first time in today's edition of the scientific journal JAMA. view more (2006-10-18)
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)
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)
Are Power and Compassion Mutually Exclusive?
The fact that many cultures emphasize the concept of "noblesse oblige" (the idea that with great power and prestige come responsibilities) suggests that power may diminish a tendency to help others. view more (2008-12-18)
Immune cells ameliorate hypertension-induced cardiac damage in mice
Researchers in Berlin, Germany have found that a specific type of immune cell, the regulatory T lymphocyte (Treg) plays an important role in hypertension-induced cardiac damage. view more (2009-06-10)
Pulse pressure identified as important risk factor for atrial fibrillation
Increased pulse pressure (the difference between systolic and diastolic blood pressure) appears to be an important predictor of the risk for new onset atrial fibrillation. view more (2007-02-21)
Corticosteroid therapy may be associated with irregular heartbeat
High doses of medications known as corticosteroids may be linked to an increased risk for atrial fibrillation, a heart rhythm disorder characterized by an irregular heartbeat. view more (2006-05-09)
