Impotence
Linked to Heart Attack Risk
Impotence can signal heart trouble in
men.
The sexual problem, also known
as erectile dysfunction, was associated with a more than threefold
higher risk of heart attack, a long-running study of more than
2,000 men finds.
Lead researcher Dr. Steven J. Jacobsen,
a professor of epidemiology at the Mayo Clinic, reported the findings
Nov. 11 at the American Heart Association's annual conference
in Orlando, Fla.
Jacobsen and his colleagues reviewed
data on sexual function and cardiovascular disease from a study
of the men from Olmsted County, Minn., that covered the years
1979-98.
The precise relationship between
impotence and heart problems is unclear. The reason: Questions
about sexual function were added to the study only in 1996. So
the number of heart attacks among men in the group since then
was too small to allow definite conclusions, Jacobsen says.
"But there is an association,"
he says. "We can't say that it is cause-and-effect, but erectile
dysfunction is a marker for future events of cardiovascular disease."
"Overall," Jacobsen adds, "men
with a [heart attack] from 1979 to 1995 were 3.5 times more likely
to have erectile dysfunction in 1996 than men who did not have"
a heart attack.
The finding can be put to everyday
medical use both by urologists, who treat erectile dysfunction,
and cardiologists, he says.
"Urologists should ask about cardiovascular
disease as well," Jacobsen says. "For physicians seeing men with
cardiovascular disease, erectile dysfunction is an issue to be
addressed."
Dr. Sidney Smith, a professor of
medicine at the University of North Carolina and a spokesman for
the American Heart Association, says the new research supplies
evidence to support what many physicians have already been doing.
"For years we have known about
a relationship between vascular disease and erectile dysfunction,"
Smith says. "This finding should place further emphasis on the
need for physicians to think beyond erectile dysfunction and at
least assess these patients for cardiovascular risk, asking whether
there are symptoms of chest pain, for example."
Jacobsen reiterates that the physical
mechanism that links erectile dysfunction with heart trouble remains
unclear. But Viagra, the popular drug for treatment of impotence,
was once considered as a potential therapy for angina, the chest
pain caused by narrowed blood vessels, he says.
Viagra works against impotence
because it enhances the effects of nitric oxide, a chemical that
relaxes smooth muscles in the penis and allows increased blood
flow.
