Studies shake up Alzheimer’s hypotheses

Two studies in people at genetic risk for Alzheimer’s disease reveal very early changes in brain structure and function that may actually precede amyloid beta deposition.

Workout in the catheter lab gives clues to ‘warm-up angina’

Improved coupling of vascular and ventricular circulation during exercise appears to underlie the phenomenon known as warm-up angina, a UK study shows.

Comprehensive overview of vascular risk factors to Alzheimer's disease

Over the last 15 years, researchers have found a significant association between vascular diseases such as hypertension, atherosclerosis, diabetes type 2, hyperlipidemia, and heart disease and an increased risk of Alzheimer's disease.

More calories consumed when eating out

Children and adolescents consume more calories and soda and have poorer nutrient-intake on days they eat at either fast-food or full-service restaurants, as compared to days they eat meals at -- or from -- home.

ECG analysis may predict risk of death from all causes

Research by Johns Hopkins cardiologists suggests that electrocardiograms (ECGs), which are widely used tests to assess the heart’s electrical activity, may have a greater and more profound future role in predicting the risk of death from any cause, not just heart problems.

Study examines role of friends in young women's body concerns

How women think their friends feel about their bodies influences their own body concerns, according to a new study by Dr. Louise Wasylkiw and Molly Williamson from Mount Alison University in Canada. Their work, which examines the role of friends in young women's body concerns, is published online in Springer's journal Sex Roles.

New insight into process of sensing

Rats use a sense that humans don't: whisking. They move their facial whiskers back and forth about eight times a second to locate objects in their environment. Could humans acquire this sense? And if they can, what could understanding the process of adapting to new sensory input tell us about how humans normally sense? At the Weizmann Institute, researchers explored these questions by attaching plastic "whiskers" to the fingers of blindfolded volunteers and asking them to carry out a location task.

Lifetime risks for total CVD are high regardless of index age

Even in men and women with an optimal cardiovascular disease (CVD) risk factor profile, the lifetime risk estimate for CVD is greater than 30 percent, and is more than 50 percent for men and women overall, according to a study appearing in November 7 issue of JAMA, a theme issue on cardiovascular disease.

Frail older adults more likely to report food insufficiency

A national study of older Americans shows those who have limited mobility and low physical activity - scientifically categorized as "frail" - are five times more likely to report that they often don't have enough to eat, defined as "food insufficiency," than older adults who were not frail.

Latinos, Hispanics in the U.S. more likely to develop major cardiovascular diseases

Hispanics and Latinos living in the U.S. are highly likely to have several major cardiovascular disease risk factors, such as high cholesterol, high blood pressure, obesity, diabetes, and smoking, according to a new, large-scale study. Risks vary among the diverse Hispanic/Latino groups, but individuals who were born in the U.S. are more likely to have multiple risk factors.

Keeping cardiovascular disease risk factors low may lead to a longer, healthier life

If you have optimal heart health in middle age, you may live up to 14 years longer, free of cardiovascular disease, than your peers who have two or more cardiovascular disease (CVD) risk factors, according to a new Northwestern Medicine study.

Study: Many Hispanic/Latino adults in the U.S. are at high risk for heart attack or stroke

A study published today in the Journal of the American Medical Association (JAMA) indicated that many Hispanic/Latino adults living in the United States are at high risk for heart attack or stroke. This risk is highest in men and in older people, born in the US or that have lived in the US more than 10 years, that prefer to speak English, are lower income, or never finished high school.
