Why the study?
Delaying percutaneous coronary intervention is a key concern in STEMI management, prompting investigation into whether door-to-balloon time predicts post-STEMI complications and hospital length of stay.
Does a door-to-balloon delay of ≥2 hours increase complications and length of hospital stay in patients with STEMI?
Population
536 patients with confirmed STEMI across 8 hospitals in Amman, Jordan
Comparison
D2B time ≥2 h vs <2 h
Design
Prospective observational study
Key result
A door-to-balloon delay of ≥2 hours was associated with a 2.22-times higher risk of complications and an increase of 0.294 days in hospital length of stay per additional hour of delay.

Longer D2B times may flag higher complication risk post-STEMI; leaves open whether shortening D2B causally improves outcomes.
Observational (n=536)
Yes
Does a door-to-balloon delay of ≥2 hours increase complications and length of hospital stay in patients with STEMI?
Odds Ratio: 2.22
A door-to-balloon time of ≥2 hours in STEMI patients is significantly associated with more than double the risk of complications and prolonged hospital stays, reinforcing the critical need for timely reperfusion.
AbuRuz et al. (2026) conducted an observational in ST-elevation myocardial infarction (STEMI) (n=536). Door-to-balloon delay ≥ 2 hours vs. Door-to-balloon time < 2 hours was evaluated on Post-STEMI complications (OR 2.22). A door-to-balloon delay of ≥2 hours was associated with a 2.22-times higher risk of complications and an increase of 0.294 days in hospital length of stay per additional hour of delay.
