During the past year, PHA has been developing an Early Diagnosis Campaign. Titled "Sometimes It's PH", the campaign emerged from recent publications showing that over the past 20 years, despite the increased visibility for PH, there has been little if any reduction in the time from onset of symptoms to point of diagnosis. With 9 FDA-approved treatments available - all over the past 17 years, eight during the past 12 years - earlier diagnosis is an essential pathway to improving patient care and extending life. Dr. Lynn Brown at the University of Utah leads the campaign and writes a column that circulates quarterly to 40,000 physicians through PHA's medical journal, Advances in Pulmonary Hypertension. Here is her newest column. It is the compelling diagnosis story of Dr. Bonnie Hudak, a pulmonologist living with PH...
Even a Physician with
PH Can Be Misdiagnosed

Diagnosing PH is often so tricky that even a patient practicing
pulmonology can experience delayed diagnosis.
That’s what happened to Bonnie Hudak, MD, a new member of the Sometimes it’s PH early diagnosis
campaign’s Education Committee.
Dr. Hudak is a pediatric pulmonologist at Nemours Children’s
Clinic in Jacksonville, Fla., where she often treats asthma and cystic
fibrosis but not PH. Yet her path to diagnosis parallels
that of many other PH patients, particularly middle-age women.
Dr. Hudak had long been treated for scleroderma and
Reynaud’s disease. Her rheumatologist knew
of the association between PH and scleroderma. Dr. Hudak maintained a healthy weight, exercising
regularly while practicing medicine and raising children. In her 40s, exercising became more difficult,
but with her busy life, she says she paid this little attention. Then while
hiking in 2004, Dr. Hudak discovered that at altitude she could not walk
uphill.
In Jacksonville she underwent an echo, an EKG and a chest
x-ray. Her doctor called the results “maybe
slightly abnormal.” He was reassured and attributed her symptoms to perimenopause
and deconditioning. He reported that the
cardiologist had considered her echo normal. “They were happy with normal, and
I was, too,” Dr. Hudak says.
Still, Saturday morning tennis games left her tired all
weekend. Once, at a neighborhood party, she
was chatting with a cardiologist friend. He told her firmly, “anyone with scleroderma
and shortness of breath with exercise has PH
unless proven otherwise.” Two weeks
later she was diagnosed by right-heart catheterization and referred to a PH
specialty center.
Dr. Hudak’s experience at Mayo Clinic in Jacksonville under
the care of Charles Burger, MD, highlights the importance of referral to
specialty centers, a key element of the Sometimes
it’s PH campaign. In a single day she received comprehensive testing
including a more detailed echo which successfully measured tricuspid
regurgitation velocity. Those administering these tests pursued results
doggedly.
Dr. Burger also admitted Dr. Hudak to the hospital for a right-heart
catheterization that included a vasodilator challenge. Without that thorough
procedure and all of the necessary testing, Dr. Hudak’s vasoreactive type of PH
would not have been discovered. Dr. Hudak has stayed on nifedipine as her sole
PH treatment and has improved from Class III to Class I. She has also participated in a clinical
trial.
In her practice Dr. Hudak now looks for a few more zebras among the horses. She also looks more carefully at the data used to interpret studies. She would advise other physicians to be more vigilant with a patient who has an underlying condition associated with PH and to work up minimal symptoms that may be due to PH. She also suggests further evaluation if existing results don’t make sense in the clinical setting.

Dr. Hudak’s experience illustrates that both patients and professionals must be more active in questioning the data and the decisions that drive diagnosis. Her unique insights will be an asset as PHA works to enhance primary and specialty care professionals’ ability to diagnose and treat PH promptly and correctly.
