African-Americans and country folk outside the so-called “stroke belt” are at higher risk for stroke death than other populations, a large new study finds.
The potato’s stereotype as a fattening food for health-conscious folks to avoid is getting another revision today as scientists report that just a couple servings of spuds a day reduces blood pressure almost as much as oatmeal without causing weight gain. Scientists reported on the research, done on a group of overweight people with high blood pressure, at the 242nd National Meeting & Exposition of the American Chemical Society (ACS), being held here this week.
Researchers with the Resuscitation Outcomes Consortium, which includes UAB, report in the New England Journal of Medicine on the first two large-scale ROC trials. Both trials were evaluating new strategies for cardiopulmonary resuscitation following cardiac arrest.

58 year old Henry Gibbs is a ballroom dancer, but he was forced to hang up his dancing shoes when a circulation condition,common among older adults, caused him severe leg pain and cramping. He went to the new University of Michigan Multi-Disciplinary Peripheral Arterial Disease Management Program and today, he’s back to pain free legs, loving life...and gliding his dancing partner across the floor.
Heart rate and blood pressure regulation may hold the key to treating unexplained chronic nausea in children. In a new study by researchers at Wake Forest Baptist Medical Center, a drug commonly used to treat a condition known as orthostatic intolerance (OI), which causes dizziness and occasional fainting when patients stand for long periods, was shown to reduce debilitating chronic nausea in patients.
New research from the Jefferson Heart Institute shows that patients in the United States who receive cardiac electrophysiological devices (CIEDs), including permanent pacemakers and implantable cardioverter-defibrillators (ICDs) are now at greater risk of contracting an infection over the life span of the device.
Giving your heart to a supportive spouse turns out to be an excellent way to stay alive, according to new research from the University of Rochester.

Type 2 diabetes patients, who face higher risk of cardiovascular disease, often take a combination of medications designed to lower their LDL or “bad” cholesterol and triglyceride levels while raising their HDL or “good” cholesterol because doctors long have thought that taken together, the drugs offer protection from heart attacks and improve survival.
Millions suffer moderate to severe leakage from their heart’s tricuspid valve, but what causes the problem is not well understood. A new study found that either dilating the valve opening or displacing the papillary muscles that control its operation can cause the valve to leak.
Low lifetime recreational activity may be a factor in peripheral arterial disease
Even though many Americans learn through community health screenings that they are at high risk for having a stroke, they rarely follow-up with their doctor for care. But a new University of Michigan study shows high-risk stroke patients are twice as likely to get follow-up care from a primary care doctor if they receive a pep talk over the telephone.
Kansas State University professor Michele Borgarelli is researching mitral valve disease, the most common acquired cardiovascular disease in dogs.

September conference focuses on interaction between key hormone and specific channels of the human kidney
As we age, it's not uncommon to lose some hearing. Of equal concern is the ability to process what we hear. According to Wichita State University audiologist Ray Hull, improving cardiovascular health appears to be the best way to help process what we hear.
A recent study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM) found that adults who consumed high fructose corn syrup for two weeks as 25 percent of their daily calorie requirement had increased blood levels of cholesterol and triglycerides, which have been shown to be indicators of increased risk for heart disease.
Recent years have seen major advances in understanding of the health effects of oxidative stress—including its potential to cause injury to the cardiovascular system. A series of expert updates on the role of oxidative stress in heart failure, atherosclerosis, and other cardiovascular diseases appears in a special symposium in the August issue of The American Journal of the Medical Sciences (AJMS), official journal of the Southern Society for Clinical Investigation (SSCI).
Healthcare providers have been dispensing advice to heart failure patients about diet and exercise and for the first time researchers have found that it really works. While self-care is believed to improve heart failure outcomes, a highlight of the recent American Heart Association scientific statement on promoting heart failure self-care was the need to establish the mechanisms by which self-care may influence neurohormonal, inflammatory, and hemodynamic function.
A new evidence review finds that a modified fat diet — and not a low fat diet — might be the real key to reducing one’s risk of heart disease.
A new system to send electricity over short distances has been shown to reliably power a mechanical heart pump. The system could free patients from being tethered to a battery or external power source, lowering their chance of infection and improving their quality of life.
Heart experts at Johns Hopkins have begun testing a new device designed to replace blocked aortic valves in patients for whom traditional open-heart surgery is considered too risky, such as elderly patients and those with other serious medical conditions. The testing is part of a nationwide study to evaluate the device, which is deployed in a minimally invasive way. The first two Maryland patients to receive the device had it put in place by Johns Hopkins doctors on July 8, 2011.
Despite changes in standard treatment practice guidelines issued by the American College of Cardiology, American Heart Association and the European Society of Cardiology several years ago, there has been no meaningful change in the nation’s practice of opening completely blocked coronary arteries with balloons and stents in the days after a heart attack, according to a new study published in the July 11, 2011, issue of Archives of Internal Medicine.
An estimated two billion people in the developing world heat and cook with a biomass fuel such as wood, but the practice exposes people – especially women – to large doses of small-particle air pollution, which can cause premature death and lung disease.
Lisa Lewis, PhD, RN, assistant professor at the University of Pennsylvania School of Nursing, is conducting research on how spiritual vignettes might increase medication adherence among hypertensive black church members."
In an examination of the appropriateness of the widespread use of percutaneous coronary interventions (PCIs), researchers found that of more than 500,000 PCIs included in the study, nearly all for acute indications were classified as appropriate, whereas only about half of PCIs performed for nonacute indications could be classified as appropriate, according to a study in the July 6 issue of JAMA.
Smoking cigarettes is a dangerous habit that many are struggling to break, but for the smokers who choose to use one of the most popular smoking cessation drugs on the market, new warnings about the risk of serious cardiovascular events are on their way.
Healthy, middle-aged smokers who take the most popular smoking cessation drug on the market have a 72 percent increased risk of being hospitalized with a heart attack or other serious heart problems compared to those taking a placebo, a Johns Hopkins-led study suggests.
A study by a global consortium of physician-scientists has identified a genetic variation that may predispose people to double the risk of having a sudden cardiac arrest, a disorder that gives little warning and is fatal in about 95 percent of cases. Although previous, smaller studies have identified some genes with a potential association with sudden cardiac arrest, this is the first study large enough to enable scientists to apply results to the general population.
Doctors at Washington University School of Medicine in St. Louis are performing a new procedure to treat atrial fibrillation, a common irregular heartbeat. Available at only a handful of U.S. medical centers, this “hybrid” procedure combines minimally invasive surgical techniques with the latest advances in catheter ablation. The two-pronged approach gives doctors access to both the inside and outside of the heart at the same time, helping to more completely block the erratic electrical signals that cause atrial fibrillation.
Heart bypass surgery is considered the gold standard for most patients with left main coronary artery disease, one of the most serious types of heart disease and one that affects thousands. But a new UCLA study reports favorable long-term outcomes for lower-risk patients with this condition who underwent angioplasty with medication-coated stents, rather than bypass surgery.
Cardiovascular disease (CVD) is the number one killer of women in the United States. Although scientists have discovered demonstrable sex differences, treatment options remain the same. In response to this important issue, the Society for Women’s Health Research (SWHR) and WomenHeart: The National Coalition for Women with Heart Disease released the long awaited 2011 10Q Report: Advancing Women’s Heart Health through Improved Research, Diagnosis and Treatment on June 21 to a captivated audience on Capitol Hill.
University of Michigan Health System study reveals why black heart attack patients wait longer for advanced treatment after arriving at some hospital emergency rooms. The differences in care may be explained by hospital quality, rather than the race of individual patients. Black patients were much more likely to go to slow hospitals than were whites, and as a result waited six hours longer to get life-saving procedures.
National reegistry results from 11-year study presented at Vascular Annual Meeting.
At the 65th Vascular Annual Meeting of the Society for Vascular Surgery®, Gilbert R. Upchurch, Jr., MD from the division of thoracic and cardiovascular surgery at University of Virginia Health System in Charlottesville, spoke about gender differences in abdominal aortic aneurysms (AAA’s).
