Marital status affects risk of heart disease, survey shows

Analysis of surveys of more than 3.5 million American men and women, administered at some 20,000 health centers across the country - believed to be the largest analysis of its kind ever performed - found that married people, regardless of age, sex, or even cardiovascular risk factors, had significantly less chances of having any kind of cardiovascular disease than those who were single, divorced or widowed.

New AAA screening program reduces number of undiagnosed at-risk men by more than 50%

A screening program for abdominal aortic aneurysms, integrated into an electronic health record, dramatically reduced the number of unscreened at-risk men by more than 50 percent within 15 months, according to a Kaiser Permanente study published today in the Journal of Vascular Surgery. An abdominal aortic aneurysm is a balloon-like bulge in the aorta, which - if ruptured - can result in death.

High HDL levels block development of aneurysms in the aorta

New research provides early evidence that 'good' cholesterol may possess anti-aneurysm forming properties. In laboratory-based investigations, scientists found that increased levels of high-density lipoproteins (HDL), the so-called good cholesterol, blocked the development of aneurysms - dangerous 'ballooning' in the wall of a blood vessel - in the body's largest artery, the aorta.
