Association of medication-assisted-therapy with new onset of cardiac arrhythmia in patients diagnosed with opioid use disorders.
No data exist on comparative risk of cardiac arrhythmias among 3 Medication-Assisted Therapy (MAT) medications in patients with opioid use disorder. Understanding MAT medications with the least risk of arrhythmia can guide clinical decision-making. ⋯ MAT users had higher risk of cardiac arrhythmia than non-users. Naltrexone is associated with the highest risk of arrhythmia, suggesting caution with naltrexone use, especially in opioid use disorder patients with pre-existing heart conditions.

Determining if a medication is effective should be easy: Either the condition is or is not improved. However, the truth is often more complex than that, including in the antiarrhythmic drug (AAD) management of atrial fibrillation. In clinical trials, AAD efficacy is usually determined by the time to first atrial fibrillation recurrence. ⋯ In clinical practice AADs, for atrial fibrillation, are prescribed to reduce symptoms/improve quality of life, which usually correlate with reduced atrial fibrillation frequency, duration, and beneficial hemodynamic effects in certain patient subgroups. Time to first recurrence is not a reliable predictor of clinical efficacy endpoints in practice. This article presents a review for the practitioner of AAD efficacy endpoints in clinical trials versus those in clinical practice and why such differences are present.
