Hair provides proof of the link between chronic stress and heart attack

Researchers at The University of Western Ontario have provided the
first direct evidence using a biological marker, to show chronic
stress plays an important role in heart attacks. Stressors such as
job, marital and financial problems have been linked to the increased
risk for developing cardiovascular disease including heart attack. But
there hasn't been a biological marker to measure chronic stress. Drs.
Gideon Koren and Stan Van Uum developed a method to measure cortisol
levels in hair providing an accurate assessment of stress levels in
the months prior to an acute event such as a heart attack. The
research is published on-line in the journal Stress.
Cortisol is considered to be a stress hormone. Its secretion is
increased during times of stress. Traditionally it's been measured in
serum, urine and saliva, but that only shows stress at the time of
measurement, not over longer periods of time. Cortisol is also
captured in the hair shaft.
"Intuitively we know stress is not good for you, but it's not easy to
measure," explains Dr. Koren, who holds the Ivey Chair in Molecular
Toxicology at Western's Schulich School of Medicine & Dentistry. "We
know that on average, hair grows one centimetre (cm) a month, and so
if we take a hair sample six cm long, we can determine stress levels
for six months by measuring the cortisol level in the hair."
In the study, hair samples three cm long were collected from 56 male
adults who were admitted to the Meir Medical Centre in Kfar-Saba,
Israel suffering heart attacks. A control group, made up of 56 male
patients who were hospitalized for reasons other than a heart attack,
was also asked for hair samples. Higher hair cortisol levels
corresponding to the previous three months were found in the heart
attack patients compared to the control group.
The prevalence of diabetes, hypertension, smoking and family history
of coronary artery disease did not differ significantly between the
two groups, although the heart attack group had more cholesterol
problems. After accounting for the known risk factors, hair cortisol
content emerged as the strongest predictor of heart attack.
"Stress is a serious part of modern life affecting many areas of
health and life," says Dr. Koren. "This study has implications for
research and for practice, as stress can be managed with lifestyle
changes and psychotherapy."

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
There is nothing glorious about what our ancestors call history,
it is simply a succession of mistakes, intolerances and violations.
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.
