Rapid Clinical Updates: Atrial Fibrillation Occurring During Acute Hospitalization-Handout

Pdf Summary

Acute atrial fibrillation (AF) refers to AF first detected or managed during an acute illness or inpatient admission, replacing the older term “secondary AF.” This term better reflects that acute illness can trigger AF in patients who already have an underlying predisposition, and these patients are at high risk for future AF recurrence.

Key inpatient management goals for acute AF are the “3 As”:
- <strong>Acute triggers</strong>: identify and treat reversible causes of AF
- <strong>AF control</strong>: choose rate or rhythm control as appropriate
- <strong>Anticoagulation</strong>: consider stroke prevention, with <strong>direct oral anticoagulants (DOACs)</strong> generally preferred

AF and heart failure (HF) are closely linked and often indicate a poor prognosis. AF—whether acute, postoperative, or previously diagnosed—is associated with HF admissions. HF in the setting of AF may result directly from the arrhythmia or from shared risk factors, and improving one condition may help improve the other.

For <strong>rate vs rhythm control</strong>, older practice often favored rate control, but newer evidence suggests rhythm control may be better, especially for symptomatic patients. Before electrical cardioversion, a <strong>TEE</strong> is recommended unless the patient is already therapeutically anticoagulated. A “wait-and-see” approach—using rate control for up to 48 hours before cardioversion if needed—appears non-inferior to immediate cardioversion. Some patients with acute AF may convert spontaneously if triggers are aggressively addressed.
