Skin Sterol Linked To Hidden Heart Disease - Study Presented At American College Of Cardiology

Simple, non-invasive skin sterol test reveals coronary artery disease in patients with no symptoms -



A study recently presented at the 54th Annual Scientific Session of the American College of Cardiology, in Orlando, Fla.
revealed that skin sterol testing can detect hardening or narrowing of the arteries, which can lead to heart disease.




"This study demonstrates that skin sterol testing can identify increased risk in patients who have no signs or symptoms of
cardiovascular disease," says Dr. James H. Stein, Principal Investigator of the study and Associate Professor of Medicine at
University of Wisconsin Medical School.



Dr. Stein's study evaluated 81 patients who had no history of cardiovascular disease. Patients' skin tissue cholesterol
levels were measured using PREVU* Point of Care Skin Sterol Test. The patients then underwent B-mode ultrasonography to
analyze carotid intima-media thickness (CIMT), which helps to measure hardening and narrowing of the arteries. CIMT is
considered an independent marker of a patient's risk for myocardial infarction and stroke.



Among the patients with high skin sterol, CIMT was also significantly higher even after adjusting for age, sex, blood sugar,
and systolic blood pressure, among other related factors. Skin sterol measures skin tissue cholesterol with a five-minute,
non-invasive test that does not require the drawing of blood or a special pre-test diet.



"More than half of the men and women who die from heart disease, die suddenly without any prior symptoms," says Dr. Stein.
"There is considerable interest in non-invasive, simple and rapidly administered tests to better assess which patients are at
risk. With this strong association with increased CIMT, skin sterol testing may help to identify asymptomatic patients who
could benefit from more intensive interventions."




About the Study


The study, conducted at the University of Wisconsin Medical School, included 81 patients without known vascular disease who
were referred for determination of CIMT. Patients underwent B-mode ultrasonography of the carotid arteries and measurement
of skin sterol using PREVU* POC. CIMT was significantly higher among patients in the highest quartile of skin sterol (p =
0.017). Skin sterol was associated with increased CIMT even after adjusting for age, sex, glucose, systolic blood pressure,
total: high-density lipoprotein cholesterol ratio, and use of lipid-lowering therapy (p = 0.031).



The findings of the study, titled Skin Cholesterol Content Identifies Subclinical Atherosclerosis in Asymptomatic Adults, by
Wendy S. Tzou. Maureen E. Mays, Claudia E. Korcarz , Susan E. Aeschlimann, and James H. Stein, will be published in the
American Heart Journal later in 2005.



About PREVU*


PREVU* Point of Care Skin Sterol Test, which does not require fasting or the drawing of blood, tests the amount of sterol, or
skin sterol cholesterol. Clinical studies have shown that as cholesterol accumulates on artery walls it also accumulates in
other tissues, including the skin. High levels of skin sterol are correlated with higher incidence of coronary artery disease
(CAD). PREVU* POC is currently being commercialized in Canada, the U.S. and Europe, where it will be available as a point of
care test. PREVU* POC is marketed and distributed worldwide by McNeil Consumer Healthcare, Canada.



About Cardiovascular Disease


According to the World Health Organization, cardiovascular diseases (CVDs), which include coronary artery disease (CAD),
stroke, inflammatory heart disease and other diseases, currently account for about 17 million deaths per year worldwide. By
2025, CVDs are expected to cause 25 million deaths annually. More people worldwide - approximately 7 million - die from
coronary artery disease than any other cause. 1



According to the British Heart Foundation, there are an estimated 268,000 heart attacks a year in the UK, which equates to
one every two minutes. There are an estimated 826,000 people under age 75 who have had a heart attack; that is 26,000 more
people than in 2003.2
