People with pulmonary hypertension frequently spend years being treated for something else. Asthma, anxiety, deconditioning and being out of shape are the usual labels, and the delay costs them time in a disease where earlier treatment matters.
The Pulmonary Hypertension Association named Cedars-Sinai a Center of Comprehensive Care on August 5. The designation, from what the announcement describes as the condition's oldest patient organization, is awarded to programs with the infrastructure and experience needed to care for people with pulmonary hypertension, a form of high blood pressure occurring in the arteries of the lungs. The Cedars-Sinai clinic includes six physicians and one nurse practitioner and combines cardiology and pulmonology.
One thing should be clear about what a designation like this is. PHA accreditation is voluntary, based on criteria developed by leading experts and confirmed through peer evaluation. The association describes it as supporting better patient outcomes, which is not the same as measuring them. It reflects program capability rather than demonstrating that patients at accredited centers live longer.
The Symptoms Are Ordinary Until They Are Not
The diagnostic delay is not a failure of attention. It is a consequence of how the disease presents.
The earliest and most common symptom is shortness of breath during exertion. Climbing stairs, carrying groceries or walking uphill becomes harder than it was. That description fits dozens of conditions, most of them far more common than pulmonary hypertension, and it fits ordinary deconditioning as well. Cedars-Sinai's own patient materials make the point plainly, noting that signs are similar to other conditions or to simply feeling out of shape, and that symptoms can develop slowly enough that a person may not realize there is a problem.
Fatigue follows, and it is similarly nonspecific. Patients are often told to exercise more, which they cannot do, which reinforces the impression that the problem is fitness or mood.
The symptoms that should raise the question are the ones that do not fit those explanations. Fainting or near-fainting during or after exertion is a warning sign that warrants prompt evaluation. So does chest pressure or pain with activity, a racing or pounding heartbeat, swelling in the ankles, legs or abdomen, a bluish tinge to the lips or fingers, and breathlessness clearly out of proportion to what a person could do a year ago.
Anyone who faints during exertion should be evaluated urgently rather than at a routine appointment. That symptom carries different weight than breathlessness alone, because it can indicate the right side of the heart is struggling to push blood through the lungs under load. Untreated, the condition can progress to heart failure.
Diagnosis Requires a Test Many Patients Never Get
Understanding why the delay happens requires knowing what confirmation involves.
An echocardiogram is usually the first step and can estimate pressure in the pulmonary arteries. It is widely available and non-invasive, and it is a screening tool rather than a diagnosis.
Confirmation requires right heart catheterization, in which a thin catheter is threaded into the pulmonary artery to measure pressure directly. That procedure is not performed in most community settings and requires referral. Because the estimate from an echocardiogram can be imprecise in either direction, patients can be reassured incorrectly or worked up unnecessarily without it.
Pulmonary hypertension is also not one disease. It is classified into groups by cause, including pulmonary arterial hypertension, disease caused by left heart conditions, disease caused by lung disease or low oxygen, chronic thromboembolic pulmonary hypertension from unresolved blood clots, and other mechanisms. Treatment differs substantially by group, and getting the classification right determines whether therapy helps.
That complexity is the argument for specialized centers. It is also why a general workup that stops at an echocardiogram can leave a patient in the wrong category for years.
Who Should Raise the Question
Certain groups carry elevated risk and should mention pulmonary hypertension by name if symptoms fit.
People with connective tissue diseases, particularly scleroderma, face substantially higher risk and are often screened routinely. So do people with congenital heart disease, HIV, portal hypertension or advanced liver disease, sickle cell disease, and a history of pulmonary embolism, since unresolved clots can produce a form that is potentially curable with surgery. Cedars-Sinai notes that its pulmonary vascular program treats pulmonary embolism and pulmonary hypertension together for this reason.
Certain diet drugs and some stimulant use have been associated with pulmonary arterial hypertension. A family history matters, because inherited forms exist.
Sleep apnea and chronic lung disease can both cause and coexist with pulmonary hypertension, which is another reason a patient with two plausible explanations may never get past the first one.
Anyone in these categories with unexplained exertional breathlessness has a reasonable basis to ask directly whether pulmonary hypertension has been considered and whether an echocardiogram is warranted.
What Specialized Care Actually Provides
Beyond the designation, the practical value of a specialized program is worth stating.
These centers typically offer right heart catheterization, expertise in classifying the disease correctly, access to the full range of approved therapies including combination regimens and infused medications that require careful management, evaluation for surgical options in clot-related disease, transplant assessment where appropriate, and access to clinical trials.
They also coordinate across specialties. Patients frequently need pulmonology, cardiology, rheumatology and sometimes hepatology or hematology working from the same plan, which is what the combined cardiology and pulmonology structure is meant to deliver.
Referral matters practically. Patients can ask a primary care clinician or cardiologist for referral to an accredited center, and the association maintains an interactive map and directory of accredited programs and specialists. Distance is a real barrier, and many centers coordinate with local clinicians so that routine monitoring happens closer to home.
Treatment has improved considerably. Pulmonary arterial hypertension remains serious and is not curable in most forms, but approved therapies can improve symptoms and exercise capacity, and the number of available options has grown substantially.
Do not stop or adjust any pulmonary hypertension medication without speaking to the prescribing clinician. This article is general information and is not a diagnosis.
Frequently Asked Questions
What is pulmonary hypertension? High blood pressure in the arteries of the lungs, which forces the heart to work harder and can lead to heart failure.
Why is it misdiagnosed so often? Its earliest symptom, breathlessness on exertion, is shared with asthma, anxiety, deconditioning and many common conditions.
What symptoms should prompt evaluation? Unexplained breathlessness with activity, and especially fainting or near-fainting on exertion, chest pressure, palpitations or swelling.
How is it diagnosed? An echocardiogram screens for it. Right heart catheterization confirms it by measuring pressure directly.
Who is at higher risk? People with scleroderma and other connective tissue diseases, congenital heart disease, HIV, liver disease, sickle cell disease or prior pulmonary embolism.
What does a Center of Comprehensive Care designation mean? It reflects voluntary accreditation against expert criteria with peer evaluation. It is not a measurement of patient outcomes.
How do I find a center? The Pulmonary Hypertension Association maintains an interactive map and directory of accredited programs.
