Men who are losing their hair may be more liable to suffer with heart
problems in comparison to those with a fuller head of hair, new
research suggests. It seems it is those men suffering with severe hair
loss on the top of their heads (vertex baldness) who could be at a
higher risk, and not those with hair loss at the front, i.e. a receding
hairline.
Researchers in Japan conducted a thorough analysis of six previous
studies from Europe and America that examined a possible connection
between male baldness
and coronary heart disease (CHD). The studies contained information on
36,990 men whose health was tracked for 11 years, and the researchers
determined that five of the studies confirmed such a link.
It was discovered that men who had severe
baldness on the top of their head were an incredible 48% more likely to
develop CHD. Those who only suffered with moderate and mild vertex
baldness were 36% and 18% at risk respectively. However, men suffering
with both frontal and vertex hair loss were 69% more likely to develop
CHD compared to those who had a full head of hair still intact.
Dr Kazuo Hara from the University of Tokyo said: “Cardiovascular risk
factors should be reviewed carefully in men with vertex baldness,
especially younger men. They should probably be encouraged to improve
their cardiovascular risk profile. But interestingly, frontal baldness
was not significantly associated with coronary heart disease.”
The explanation between the connection is still uncertain, but
researchers believe increased sensitivity to male hormones, insulin
resistance and inflammation in blood vessels could be key factors behind
the hair loss and heart disease correlation, although further studies
need to be carried out in the future to explore the link.
Another interesting aspect between the hair loss and CHD link is the
fact Minoxidil (a popular hair loss treatment, contained in Regaine),
was first produced to bring down high blood pressure – a severe risk
factor of heart disease. Experts believe that Minoxidil works to dilate
small blood vessels in the scalp, thus helping to boost blood flow and
the supply of oxygen and nutrients to the hair follicles.
Other authors involved in the study said that in their meta-analysis,
“vertex baldness was significantly associated with an increased risk of
CHD among younger men as well as among all participants, and the
association was dependent on the severity of baldness. Vertex baldness
is more closely associated with systemic atherosclerosis (hardening of
the arteries) than with frontal baldness.”
However, Doireann Maddock, senior cardiac nurse at the British Heart
Foundation, commented on the study, saying: “Although these findings are
interesting, men who’ve lost their hair should not be alarmed by this
analysis. It’s more important to pay attention to your waistline than
your hairline.”
