Post‐dilatation trepidation: Post‐dil is “no big dil”

• Selective stent post‐dilatation (PD) in a cohort of STEMI patients did not affect major adverse cardiac events but it did decrease device‐oriented composite events, a secondary composite end point of less clear significance.
• This study suggests that selective stent PD in STEMI does not increase the incidence of acute no‐reflow or long‐term adverse clinical events.
• In primary PCI for STEMI, if the stent appears under‐expanded, then PD, perhaps guided by intravascular imaging (which was not reported in this study), is reasonable.
