Key result
Scene departure to cath lab ≤30 minutes linked to ~11-fold higher odds of PCI ≤90 minutes.
Why the study?
Current guidelines recommend a first medical contact to percutaneous coronary intervention interval of <=90 minutes for STEMI, and the study aimed to determine whether prehospital time intervals were associated with achieving this performance metric.
Are specific prehospital time intervals associated with achieving first medical contact to percutaneous coronary intervention in ≤90 minutes in patients with acute STEMI?

Are specific prehospital time intervals associated with achieving first medical contact to percutaneous coronary intervention in ≤90 minutes in patients with acute STEMI?
Odds Ratio: 11.1 (95% CI 3.4–36)
Meeting specific prehospital timing benchmarks, particularly scene departure to catheterization laboratory table time ≤30 minutes, significantly increases the likelihood of achieving guideline-recommended first medical contact to PCI times in STEMI patients.

Scene departure to cath lab ≤30 min may aid timely PCI in STEMI; extends observational data on prehospital benchmarks but requires prospective validation.
Studnek et al. (2010) conducted an observational in ST-elevation myocardial infarction (n=181). Scene departure to arrival on cardiac catheterization laboratory table ≤30 minutes vs. Extended table times (>30 minutes) was evaluated on Achieving percutaneous coronary intervention in ≤90 minutes (first medical contact to percutaneous coronary intervention) (OR 11.1, 95% CI 3.4-36.0). Patients with a scene departure to cath lab table time of ≤30 minutes were more likely to achieve percutaneous coronary intervention in ≤90 minutes (OR 11.1; 95% CI 3.4-36.0).
