Heart Failure Often Takes Two Years to Diagnose. Echo Access Is a Big Reason Why.

A patient keeps propping themselves up on a second pillow because lying flat makes it hard to breathe. Another one notices their ankles swell by late afternoon, or that the walk from the truck to the clinic door takes a rest stop it never used to. Most of them never mention it. And when they do, the symptoms sound like a dozen other things: age, weight, a long winter of not moving much, asthma acting up.

That is how heart failure hides. New consensus research from the UK puts a number on how long it stays hidden: from first symptoms to a confirmed diagnosis, the path can stretch past two years.

What the study found

The study, published in BMC Primary Care by researchers at the University of Leicester, used a structured Delphi process with heart failure patients and clinicians from primary and specialist care. The goal was to agree on why diagnoses come so late and which warning signs should trigger a closer look. A few findings stand out for anyone running a clinic or care facility:

• Heart failure is frequently diagnosed during a hospital admission, often after symptoms have been present for a long time. Patients diagnosed in the hospital tend to face higher mortality, partly because they are sicker by the time anyone confirms what is going on.
• Fewer than half of patients who eventually receive a diagnosis reported their symptoms early, and only about a quarter received the recommended diagnostic tests or specialist referrals when they first presented.
• When clinicians ranked the system-side barriers, lack of echocardiogram access in primary care made the top five, alongside limited NT-proBNP testing and fragmented care between settings.

Read that last one again. One of the biggest reasons heart failure goes undiagnosed is that the confirming test lives somewhere else.

The echo bottleneck, Montana edition

The research comes out of England, where a patient might be thirty minutes from an echo lab and still wait months. Montana runs on a different scale entirely. A provider in Circle or Chester who suspects heart failure may be looking at a referral that involves a half-day drive each way for the patient, plus whatever the hospital's echo schedule looks like once they get there. For a skilled nursing resident, add wheelchair transport, a staff escort, and a day of disruption for a test that takes under an hour.

So the suspicion gets watched instead of tested. The provider makes a note, adjusts a medication, asks the patient to come back in a couple of months. It is a reasonable decision inside an unreasonable set of options. The UK study essentially documents what happens next: the two years tick by, and the diagnosis finally arrives through an ER door.

The confirmation pathway for heart failure is well established. Symptoms and exam findings raise the question, a natriuretic peptide blood test sharpens it, and an echocardiogram answers it. None of those steps is exotic. The problem is almost never the medicine. It is the geography between the patient and the machine.

Shortening the loop

This is the part of the problem that logistics can actually fix. When the echo comes to the clinic or the facility instead of the patient going to the echo, the calculus changes for everyone involved.

That is the model we run at Big Sky Imaging. Our technicians bring echocardiography and EKG on-site to provider offices and care facilities across Montana, with availability that runs monthly or same-week depending on the region. Every study is interpreted through Rapid Radiology's board-certified network, and the report flows back to the ordering provider. The patient never leaves the building. The facility never books a transport van. The provider who raised the question gets an answer while the question is still fresh.

EKG pairs naturally with this workflow, and in our covered markets it is often available same-day. For cardiology practices trying to manage a rural referral base, that combination means symptom documentation and baseline imaging can happen close to the patient, with the specialist visit reserved for the patients who actually need it.

None of this replaces cardiology, and it is not meant to. Diagnosis belongs to the care team, and complex cases will always need the specialist's eye. The point is the middle step. When a provider suspects heart failure and needs the picture, the wait for that picture should not be the reason a diagnosis slips into next year.

Worth a conversation

The Leicester team built their indicator list hoping it would end up inside electronic records, flagging the patient with an elevated NT-proBNP and no referral, or the one on a loop diuretic with no imaging on file. Those flags only help if there is a practical next step behind them. In Montana, on-site echo can be that step.

The research summarized here comes from Lawson and colleagues, "Developing core indicators for identifying people at risk of delayed heart failure diagnosis," published in BMC Primary Care. The full paper is open access and worth the read.
