High blood pressure service increases referrals
1 June, 2020
A clinical service and primary care outreach program focused
on hormonal causes of high blood pressure — the first of its kind in Victoria —
has led to earlier screening and diagnosis of primary aldosteronism.
Primary aldosteronism (PA), or Conn’s Syndrome, is
characterised by excessive secretion of the hormone aldosterone from the
adrenal glands. This overproduction leads to the retention of sodium in the
body, resulting in high blood pressure which is difficult to control. PA carries a higher risk of heart arrhythmia,
heart attacks and strokes than ordinary hypertension.
The Endocrine Hypertension Service at Hudson Institute and
Monash Health has facilitated an increase in referrals from general
practitioners for primary aldosteronism screening over three years of
operation. This has resulted in the earlier diagnosis and treatment of PA. The
results were published in the Internal Medicine Journal, the official journal
of internal medicine in the Adult Medicine Division of The Royal Australasian
College of Physicians, to ensure the findings were distributed widely to
doctors around Australia.
PA is the most common secondary cause of hypertension,
affecting 5-10 per cent of hypertensive patients in primary care and up to 30
per cent in tertiary centres, based on international studies.
The Endocrine Hypertension Service is the first of its kind
in Victoria and one of few in Australia. Over the three years since launching,
patients have become less likely to have pre-existing heart or kidney damage at
the time of referral, and more likely to improve their blood pressure with
fewer medications.
“Our Endocrine Hypertension Service saw a six-fold increase
in patients referred for early testing, two-fold decrease in end-organ damage
and consistent blood pressure reduction with targeted treatment,” said Dr Jun
Yang, the study’s senior author.
“Our study shows that general practitioners are more likely
to screen for primary aldosteronism when there is a streamlined diagnostic
pathway, such as our Endocrine Hypertension Service, together with an education
program,” Dr Yang said.
“Most patients with high blood pressure rely on their GPs
for testing and treatment. Increased screening among GPs will lead to more
diagnoses and therefore benefit more Victorians/Australians.”
“Our goal is to accurately diagnose every patient affected
by PA,” Dr Yang said.
Dr Yang was recently awarded a NHMRC Investigator Grant
Emerging Leadership (Level 1) for her research into primary aldosteronism.
How science helped Jun Yang’s family
Dr Jun Yang wishes she had more time with her grandfather.
He died aged just 56 from a stroke caused by high blood pressure, when Jun was
one-year-old.
Dr Yang, an endocrinologist and research scientist with the
Cardiovascular Endocrinology Group at Hudson Institute, studies an
under-diagnosed cause of high blood pressure in Australia known as primary
aldosteronism, or Conn’s Syndrome. With Professor Peter Fuller, she established
the Endocrine Hypertension Service at Hudson Institute and Monash Health, which
has witnessed a six-fold increase over three years in PA diagnoses.
Dr Yang has diagnosed and treated her father, mother and
94-year-old grandmother with the condition, successfully reducing their high
blood pressure levels with a targeted treatment.
Dr Yang’s father takes just one quarter of a tablet, a
targeted medicine that blocks aldosterone action, per day for blood pressure.
He used to take four pills, and still had poor blood pressure. He has stable kidney
function and no heart issues. Her mother is also on a quarter of a tablet with
excellent results, and her grandmother’s blood pressure has also reduced with
treatment.
Dr Yang can hardly believe the results. She only wishes her
research findings ‘could go back in time’, to help her grandfather.
What is primary aldosteronism?
·
Primary aldosteronism or PA is excessive
production of the hormone aldosterone from the adrenal glands.
·
It causes high blood pressure which is difficult
to control.
·
Patients have a higher risk of heart arrythmia,
heart attacks and strokes.
·
It is likely under-diagnosed.
·
Overseas data shows somewhere between one in 20
and up to 1 in 10 hypertensive patients have a PA diagnosis.
