Amiodarone Patches Failed to Prevent Heart Arrhythmia
A large clinical trial found that drug-soaked patches did not lower the risk of atrial fibrillation after heart surgery.

Do you trust neutral clinical trials that report no benefit as much as successful positive trials?
The BEAT-AF trial found that applying amiodarone-soaked patches during cardiac surgery failed to reduce the incidence of postoperative atrial fibrillation. Researchers found no statistically significant difference in patient outcomes compared to a saline-soaked placebo.
Why it matters
The study was designed to build on positive findings from earlier research involving an amiodarone hydrogel spray. The failure to demonstrate efficacy in this trial suggests that localized patch delivery may not be a viable intervention for reducing heart rhythm complications post-surgery.
The BEAT-AF trial randomized 502 patients to receive amiodarone-soaked patches at a dosage of 150 mg per 3 mL or saline placebos. Researchers reported no significant differences in hospital stay lengths, adverse cardiac events, or thyroid function between the groups.
The players
EACTS
The European Association for Cardio-Thoracic Surgery is a professional organization that hosts international meetings to share cardiovascular surgical research.
Jilin Heart Hospital
Located in China, this facility served as the primary site for patient enrollment in the BEAT-AF study.
The details
During the procedure, surgeons placed two oxidized cellulose patches containing amiodarone over the heart's atrial ganglionated plexuses. These were applied to both the left and right atria to attempt to prevent rhythm disturbances following the operation.
Timeline
The BEAT-AF trial findings were presented at the EACTS meeting in 2026.
The Big Picture
This trial marks a departure from the positive results established by the amiodarone hydrogel spray trial. The findings suggest that despite earlier promise for localized drug delivery, clinical results are not always replicable across different application techniques.
Patients preparing for elective cardiac surgery should consult their surgeons about proven methods for managing postoperative recovery. This trial indicates that current protocols remain standard, as this specific patch technique did not demonstrate clinical benefits.
The takeaway
While this study did not produce the desired reduction in arrhythmias, researchers intend to examine the dataset for other potential medical signals. Patients are reminded that standard surgical recovery protocols remain the gold standard following elective heart operations.
