(Medical-NewsWire.com, April 26, 2013 ) London, UK -- New hair analysis can apparently reveal if seniors have higher stress hormone levels, the effect of which is the increase in heart disease and stroke, according to a new study.
Unlike the standard blood test that was utilized beforehand which test provides information regarding stress hormone levels at a precise point in time, the new test type can reveal trends in levels of stress hormone cortisol over a span of several months.
The study was recently published in the Journal of Clinical Endocrinology & Metabolism, and found that seniors with higher long-term levels of cortisol were much more likely to have heart disease.
"Like high blood pressure or abdominal fat, the findings suggest elevated cortisol levels are an important signal that an individual is at risk of cardiovascular disease," study co-lead author Dr. Laura Manenschijn, of Erasmus Medical Center in the Netherlands, said in a news release from the Endocrine Society.
"Because scalp hair can capture information about how cortisol levels have changed over time, hair analysis gives us a better tool for evaluating that risk," she explained.
The researchers looked over 1.2-inch samples of hair from over 280 individuals that were aged between 65 and 85, and determined that participants' levels of the hormone cortisol over a three-month period. What the study found was that high cortisol levels were more likely to exist in those who had a history of coronary heart disease, stroke, and peripheral artery disease.
"The data showed a clear link between chronically elevated cortisol levels and cardiovascular disease," the other lead author, Dr. Elisabeth van Rossum, of Erasmus Medical Center, said in the news release. "Additional studies are needed to explore the role of long-term cortisol measurement as a cardiovascular disease predictor and how it can be used to inform new treatment or prevention strategies," she said.
