🚩Published in @HRS_O2Journal: The PACEMAN study compared leadless pacing vs conduction system pacing in 103 real-world patients.
➡️Leadless = faster, 100% acute success CSP = narrower QRS, more physiological activation
➡️Complications were low in both groups
🌟Patient selection is everything.

Published in @HeartRhythmO2: OAC alone vs OAC + antiplatelet therapy in #AF with stable #CAD

Meta-analysis of 5 RCTs, 5,052 pts:
✅ No difference in MI, stroke, or CV mortality
🩸 OAC + SAPT = significantly more major bleeding (OR 1.97, P=.049)

➡️ OAC monotherapy may be enough
