Canadian healthcare professionals unaware that sex matters in heart disease

 

Toronto - Physicians are short-changing Canadian women when it
comes to taking care of their hearts, says Dr. Susan K. Bennett,
delivering the Heart and Stroke Foundation of Canada Lecture at
the Canadian Cardiovascular Congress 2008.
 

"Doctors need to hear the message about the significant deficits
in women's heart health care and bridge this gender gap," says
Dr. Bennett, director of the women's heart program at George
Washington University Hospital.
 

She says that as the public's awareness and knowledge about
women's risk factors and warning signs increases thanks to
increased public awareness campaigns, more and more women are
going to their doctors with their concerns. Yet often, she says,
their healthcare providers are not up to date on how women can
experience heart disease differently than men. "Healthcare
professionals need to be educated about women's cardiovascular
issues and meet the public's expectations," says Dr. Bennett.
 

"There is a serious gap in awareness in medical professions,"
she says. "Data suggests that women do not receive the same care
that men do. We need to explore the reasons why and close that
gap.
 

"Meetings such as the Canadian Cardiovascular Congress are
opportunities to work towards closing this gender gap and meeting
women's needs for more effective care delivery."
 

Heart disease and stroke are the leading cause of death in Canada
and responsible for the death of one in three women. Bennett
notes that when it comes to prevention and treatment of heart
disease, there are some worrisome disparities with respect to
women's heart health on both sides of the border.
 

The 2007 Heart and Stroke Foundation report card revealed that
Canadian women's heart health has not kept pace with men's. The
reasons for this are still unclear. The report concluded that
contributing factors may be systemic, social, and biological -
and answers need to be found.
 

Why the gap?
Bennett says physicians are either not entirely comfortable with
the issue of gender differences or are not ready to meet women's
needs. "There's a huge population within the medical care
community - obstetricians, gynaecologists, emergency room
physicians, family doctors - who still haven't gotten the
message."
 

Bennett points to a 2005 American Heart Association poll which
found a striking lack of knowledge in the medical community.
Only eight per cent of primary care physicians and 17 per cent of
cardiologists correctly knew that more American women than men
die of heart disease.
 

She says there is a similar lack of knowledge among Canadian
healthcare professionals and points to the fact that fewer women
are referred to a cardiologist following a heart attack, they
have lower rates of undergoing coronary artery bypass surgery and
angioplasty, and they are less likely to be transferred to
another facility for treatment.
 

Bridging the gap
Bennett calls on healthcare professionals to break down the walls
and become a bridge for women's heart health.
 

For this to happen, she says more efforts need to be made to get
the message about women's heart health needs to the medical care
community.
 

In her opinion, physicians frequently underestimate a women's
risk for heart disease. "Their perception of women being at low
risk for heart disease leads to inaction," says Bennett. "We need
more emphasis on women's uncontrolled hypertension, high
cholesterol levels, and lifestyle risks."
 

She says that dealing with prevention issues is key. "But doctors
are busy and often don't have the time to discuss prevention,"
she says.
 

It doesn't help, either, that clinical trials still under-
represent women to a considerable degree. When results are in and
a new drug or device is declared advantageous, results may not
apply to women because women made up such a minority of the
clinical trial population that no solid conclusions can be drawn.
 

"Not all drugs work the same in men and women but we don't know
enough about these differences to exploit their advantages or
disadvantages," Dr. Bennett said.
 

Dr. Bennett notes that decision-making seems to be slower when
women present to the emergency department with heart attack
symptoms and they receive the necessary tests somewhat later than
men. "Once they get to the cardiac cath lab, they get reasonably
good care," Dr. Bennett observed, "but mortality rates among
women are still higher than they are for men."
 

That was the impetus behind the launch of the Heart Truth
campaign in the U.S., the campaign to get women to talk to their
doctors about their risk for heart disease. The Heart and Stroke
Foundation of Canada adapted the campaign and launched it in
Canada in 2008. Bennett cites that public awareness in the U.S.
has consistently gone up since the program was introduced but
while the majority of women claim to know it's the number one
killer, they think, "it's not my number one killer."
 

"As professionals, we need to be reminded that there is a
significant deficit in heart healthcare for women," says Dr.
Lyall Higginson, president of the Canadian Cardiovascular
Society.  "We need to work diligently to improve. This annual
meeting is important to educate professionals on issues like this
and it is why The Heart Truth campaign is vitally important to
improve cardiovascular health for Canadian women."
 

"The Heart Truth has done an amazing job of educating women and
encouraging women to seek cardiovascular care," says Bennett, who
is a spokesperson for The Heart Truth in the U.S. "Now healthcare
professionals need to get the message. As awareness among women
does increase, female patients are going to expect a better level
of care.
 

"Physicians make unconscious choices sometimes, whether talking
to a male or female patient and just the interaction itself
determines how you end up treating your patient - gender is a big
part of it and it's not going away."
