BOSTON — Patients with COPD who have exacerbations requiring hospitalization should be monitored for cardiac arrhythmias, investigators said.
This recommendation is based on results of a study of medical records showing that among more than 20,000 hospitalizations for patients with COPD without concurrent heart failure (HF), 40% patients had at least 6 minutes of daily atrial fibrillation (AF) burden, and nearly half of these patients had at least an hour of daily AF burden; patients with COPD and concurrent HF had similar daily AF burdens, reported Trent Fischer, MD, MS, senior principal scientist at Medtronic in Minneapolis.
“We can conclude that AF burden increases in the weeks after a hospitalization for COPD if they don’t have a concurrent diagnosis of heart failure. Also, having concurrent heart failure increases the risk of atrial fibrillation and increases the atrial fibrillation burden around the time of COPD hospitalization,” he said in a rapid-fire oral abstract session at the CHEST Annual Meeting.
The findings indicated a need for increased vigilance for AF around the time of a serious COPD exacerbation and may explain at least some of the increased risks for stroke observed in patients who are hospitalized for COPD exacerbations, he said.
Retrospective Study
They drew data from 2007 through 2021 on patients with implantable cardioverter defibrillators, cardiac resynchronization therapy devices, pacemakers, and implantable cardiac monitors, using the Optum de-identified electronic health record dataset linked with Medtronic’s CareLink database to conduct a retrospective analysis.
They looked at admissions for COPD linked to available device diagnostic parameters between 30 days prior to and 60 days after admission for COPD.
They identified a total of 20,056 COPD hospitalizations for patients with concurrent HF and 3877 for those without HF.
Among patients with HF, 43% had a daily AF burden of at least 6 minutes, and 22% had at least 1 hour of irregular rhythms. Among patients without HF, 40% had at least 6 minutes of irregular rhythms daily, and 18% had at least 1 hour.
Among patients with HF, the daily average AF burden increased from a baseline of 158 min/d 30 days before an admission to 170 min/d at admission, returning to baseline by 20 days after hospitalization.
For patients without HF, the AF burden increased from 107 min/d at baseline to 113 min/d during hospitalization and returned to baseline by 20 days after hospitalization.
Confounding Factor?
In the Q&A, session moderator Krishna Sundar, MBBS, MD, FCCP, a pulmonary, sleep medicine, and critical care medicine specialist at St. John’s Medical Center in Jackson, Wyoming, said that when patients with HF get admitted for COPD exacerbations, their HF typically worsens and asked Dr. Fischer how he could tell the difference.
“I know there’s a lot of interaction between heart failure and COPD. They’re well-know comorbidities, and the exacerbation of one can bring on worsening of the other. At least with this database, we can’t really tease out any sort of differences,” Dr. Fischer replied.
“I think that a diagnosis of COPD exacerbation is pretty well laid out, but it’s sometimes difficult to separate worsening of heart failure in these patients, and often these patients get treated for both problems. It’s clear that it’s the heart failure patients who are having more atrial fibrillation episodes, which is not surprising, but the question is how much is the COPD exacerbation contributing to the atrial fibrillation?” said Dr. Sundar.
The study was supported by Medtronic. Dr. Fischer is employed by the company. Dr. Sundar reported no relevant financial relationships.
