Obstructive sleep apnea (OSA) is associated with an increased risk of stroke in middle-aged and older adults, especially men, according to new results from new research supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. Overall, sleep apnea more than doubles the risk of stroke in men.
In a rigorous new review of the antiarrhythmic drug dronedarone (Multaq), researchers at the Cedars-Sinai Heart Institute conclude that the controversial drug is only modestly effective and has no clear safety benefits. The review, to be published in the April 23 issue of the Journal of the American College of Cardiology, assessed data on dronedarone submitted during the drug's FDA approval process and determined that dronedarone is 50 percent less effective than amiodarone (Cordarone), a frequently used treatment for atrial fibrillation, a common type of heart rhythm disorder.

Findings will be published tomorrow by the Public Library of Science (PloS One).
New research finds that there is an inverse association between the level of supine (lying face up) systolic blood pressure measured on admission to an intensive care unit for acute chest pain and risk of death at one year, with those patients having high systolic blood pressure having a better prognosis after a year, according to a study in the March 24/31 issue of JAMA.
Patients who suffer from plaque-related narrowing of a carotid artery but are not good candidates for open surgery may be eligible to participate in a clinical trial at Cedars-Sinai Medical Center of a minimally invasive procedure designed to open carotid arteries the way angioplasty and stenting clear arteries of the heart.

Chronic feelings of loneliness take a toll on blood pressure over time, causing a marked increase after four years. A new study shows, for the first time, a direct relation between loneliness and larger increases in blood pressure four years later—a link that is independent of age and other factors that could cause blood pressure to rise.
An experimental thyroid drug reduces cholesterol without the troublesome side effects experienced by some people on statins, according to a study published today in The New England Journal of Medicine. An international team of investigators at Johns Hopkins Medical Institutions, the Karolinska University Hospital and Institute, and The Feinstein Institute for Medical Research tested a substance called Eprotirome in patients with high cholesterol.
People whose “bad” cholesterol and risk of future heart disease stay too high despite cholesterol-lowering statin therapy can safely lower it by adding a drug that mimics the action of thyroid hormone. In a report published in the Mar. 11, issue of the New England Journal of Medicine, Johns Hopkins and Swedish researchers say an experimental drug called eprotirome lowered cholesterol up to 32 percent in those already on statins, an effect equal to that expected from doubling the statin drug doses, without harmful side effects.
New Saint Louis University research found that beta blockers are underused in heart failure patients who receive an implantable cardiac device, suggesting a reliance on technology rather than conventional drug therapy.
The first edition of James Toole’s Cerebrovascular Disorders, published in 1967, was the first modern stroke textbook. Now, more than 40 years later and through five editions, a new edition has been released for both specialists and residents.
Researchers from Mount Sinai School of Medicine have found that patients admitted to hospice care who have an implantable cardioverter defibrillator (ICD) are rarely having their ICDs deactivated and are receiving electrical shocks from these devices near the end of life.
New data reported at a scientific meeting from the Carotid Revascularization Endarterectomy vs. Stenting Trial (CREST) finds the overall safety and efficacy of the two procedures essentially the same. But in those age 69 and younger, the stenting works better than the surgery, says the chair of biostatistics at UAB and other researchers, and the surgery seems to work better in those age 70 and higher.
The CREST trial that compared traditional surgery with less-invasive stenting to clear dangerously clogged carotid arteries in the neck is being called "seminal and robust."
A large nationwide study that includes neurologists from Mayo Clinic has found that blacks are substantially less likely than whites to know that they have atrial fibrillation or to use warfarin, the most common treatment for the condition. Atrial fibrillation, an abnormal heart rhythm, significantly increases risk of stroke. Warfarin is known to reduce that risk.

A study by Indiana U. prof Marieke Van Puymbroeck found that a modified version of cardiac rehab helped reduce risk factors for stroke after Transient Ischemic Attacks, or "mini strokes." No post-TIA rehab exists to help prevent future strokes.
When stroke strikes, choking off blood supply to the brain, every minute counts: Nearly 2 million neurons die each minute a stroke is left untreated, making it a race to recognize symptoms so that lifesaving “clot-busting” drugs can be administered. Forty-five percent of Americans – 135 million people -- are more than an hour away from primary stroke centers, the facilities that are best equipped to care for them if they are stricken by the condition, according to new research led by the University of Pennsylvania School of Medicine.
Creation of a genetic risk score comprised of multiple genetic markers associated with cardiovascular disease (CVD) was not associated with significant improvement in CVD risk prediction in a study that included more than 19,000 women, according to a study in the February 17 issue of JAMA.

New research from the University of Alabama at Birmingham (UAB) says low potassium levels produce an increased risk of death or hospitalization in patients with heart failure and chronic kidney disease (CKD). In findings reported in January in Circulation: Heart Failure, a journal of the American Heart Association, the researchers say that even a mild decrease in serum potassium level increased the risk of death in this patient group.
Cardiologists and heart imaging specialists at 15 medical centers in eight countries, and led by researchers at Johns Hopkins, have enrolled the first dozen patients in a year-long investigation to learn whether the subtle squeezing of blood flow through the inner layers of the heart is better than traditional SPECT nuclear imaging tests and other diagnostic radiology procedures for accurately tracking the earliest signs of coronary artery clogs.
