US Cardiac electrophysiologists meet reimbursement reality and don’t like it.

It’s been a while but Anish Koka, a one time regular writer on THCB and occasional THCB Gang member, is back publishing up a storm on his Substack channel. You may recall that his political and clinical views don’t always mesh with some of the wooly liberals we feature on THCB (cough, cough, me), but we are delighted to be back publishing some of his pieces–this one is on reimbursement.–Matthew Holt

The subspecialty of Cardiology known as electrophysiology has seen explosive growth over the last few decades in large part because of a massive expansion in the suite of procedures now offered to patients. It used to be that electrophysiologists would spend the majority of their careers implanting pacemakers and defibrillators, but the last 2 decades saw an explosion in electrophysiology procedures known as ablations. Ablations essentially involve burning cardiac tissue in a strategic manner to get rid of arrhythmias that may be afflicting a particular patient. The path humans took from first taking an electrical picture of the heart with a surface ECG to putting catheters into the heart to map and treat dangerous arrhythmias is one of the great achievements of the modern era.

Giants of the field like the recently deceased Mark Josephson essentially created a field by going where no humans had gone before. Dr. Josephson did much of his work in Philadelphia at the University of Pennsylvania publishing seminal papers that lead to a greater understanding and eventual treatment of previously incurable malignant arrhythmias. As is true of all trailblazing work in medicine , there were no reimbursement codes in the beginning , just desperate patients with no place to turn.

The procedures being embarked on were rare and the patients were very complex. The renumeration that was awarded from Medicare was reflective of this. But two things almost always happen once a highly reimbursed procedure code comes on line – technological advances makes the procedure easier, and the population that the procedure is intended for massively balloons.

How Concerned Should Patients Be About An Irregular Heartbeat?

As many industries and individuals are struggling publicly with burnout, a new study from the European Journal of Preventative Cardiology links the “burnout syndrome” with atrial fibrillation (afib). The findings are both interesting and valuable. In general, the public benefits from anything that can raise awareness of heart disease, because early intervention directly impacts improved patient outcomes.

However, headlines that describe afib as a “deadly irregular heartbeat” go too far in the name of public awareness. The truth is, afib is not a sudden killer like a heart attack, cardiac arrest, or stroke. While afib is undeniably serious, it can often be identified in advance and managed with evaluation and treatment.

Afib is a very common arrhythmia that has numerous risk factors, including hypertension, diabetes, obesity, and sleep apnea, to name just a few. When the heart goes into atrial fibrillation, the upper chambers go into a fast, chaotic and irregular rhythm that often makes the pulse race and feel irregular. Other symptoms can include palpitations, shortness of breath, and dizziness. Some people may not have any symptoms at all. Stroke is the most devastating consequence of atrial fibrillation, but is rarely the first manifestation of the disease.

It is also important to note that afib may not always be present. For this reason, often the arrhythmia is gone by the time someone seeks medical attention, making the arrhythmia harder to diagnose. Fortunately, consumer devices, such as the new Apple Watch, have algorithms to help detect atrial fibrillation. These technologies hold immense promise. They are already helping many people manage their health, and even potentially diagnose some people who never knew they had afib.

Why Your A-fib Diagnosis May Not Be as Bad as You Think It Is

With breathtaking speed, atrial fibrillation has gone from “Huh?” to parlance.

“A-fib”, a common cardiac cause of palpitations, is now in the front ranks of evils lurking to smite our well-being. There is no mystery to this transformation. In 2013, the Food and Drug Administration licensed three new drugs to prevent a stroke, the fearful complication of A-fib: apixaban (Eliquis), rivaroxaban (Xarelto) and dibatigatran (Pradaxa).

This unleashed the full might of pharmaceutical marketing: the scientific data for efficacy that convinced the FDA is tortured till it convinced “thought leaders” whose opinions convinced influential journalists. Sales pitches populate print, broadcast and social media. A-fib is now more than a worrisome disease; it is a product line.

Nonetheless, A-fib can be scary for those afflicted. There are lots of choices to make and a lot of confusing, conflictual and counter-intuitive advice to deal with. Troubled by this situation, Mr. X recently sought me out to have a dialogue about his situation.

Mr. X is a 70-year-old business executive who has enjoyed robust good health and is on no prescription drugs. He exercises vigorously and is a consumer of various over the counter treatments purveyed as salutary. Like many “health-wise” Americans, he also takes 80mg of aspirin a day unaware that the benefit is minimal at best and is counterbalanced by a similar magnitude of risk.

A month earlier he had the sudden onset of palpitations, a fluttering in his chest that made him exceedingly anxious and somewhat breathless. He waited an hour before asking his wife to drive him to the local emergency room. By the time he was first seen, another hour passed. The diagnosis of A-fib followed. Another hour passed to find the consulting cardiologists debating whether to convert the A-fib to a normal rhythm by using drugs or an electrical shock.

Before they could decide, Mr X’s heart decided to behave again; he was back in a normal rhythm. It was a frightening experience for Mr. and Mrs. X. He left the ED shaken and shaky.

He also left with a follow-up appointment with a cardiologist who specialized in rhythm disorders and a prescription for a drug that slowed the conduction of electrical impulses initiating in one heart chamber, the right atrium, and traversing the heart. The normal “pacemaker” is a specialized cluster of muscle cells in the right atrium that discharges at regular intervals, initiating a current that causes the heart to contract in the synchronized fashion termed Normal Sinus Rhythm.

In A-fib, for reasons that are poorly understood, multiple pacemakers form in the right atrium leading to chaotic discharging and circular currents in the right atrium. How many of these impulses manage to exit the atrium to traverse the heart depends on the capacity of the conducting tissues; most just stay confined to the atrium causing it to quiver ineffectively.

How the iPhone Might Disrupt The Medical Device Industry

Doctors wanting to determine a patient’s atrial fibrillation burden have a myriad of technologies at their disposal: 24-hour Holter monitors, 30-day event monitors that are triggered by an abnormal heart rhythm or by the patient themselves, a 7-14 day patch monitor that records every heart beat and is later processed offlineto quanitate the arrhythmia, or perhaps an surgically-implanted event recorder that automatically stores extremes of heart rate or the surface ECG when symptoms are felt by the patient. The cost of these devices ranges from the hundreds to thousands of dollars to use.

Today in my clinic, a patient brought me her atrial fibrillation burden history on her iPhone and it cost her less than a $10 co-pay. For $1.99 US, she downloaded the iPhone app Cardiograph to her iPhone.

Every time she feels a symptom, she places her index finder over the camera on the phone, waits a bit, and records a make-believe rhythm strip representing each heart rhythm. With it, comes the date and time.
