Women post-OHCA get less angiography

Coronary angiography and reperfusion therapy following out-of-hospital cardiac arrest in women
Resuscitation Plus · Added 8 September 2026

Nationwide Swedish cohort of 8,641 post-OHCA admissions — women were less likely to undergo coronary angiography and PCI than men, yet intervention rates were even once angiographic findings were accounted for, and a third of angiographed women without shockable rhythm or ST elevation had significant coronary disease.

Study type

Registry

Design

Nationwide registry cohort

Participants

8,641 patients admitted alive after OHCA (29.4% women)

Main finding

Coronary angiography in 31.5% of women vs 51.0% of men; women less likely to undergo angiography (OR 0.77, 95% CI 0.66-0.90) and PCI (OR 0.76, 95% CI 0.64-0.90); after adjusting for angiographic findings intervention rates were similar (OR 0.97, 95% CI 0.80-1.18); significant coronary disease in 31% of angiographed women with non-shockable rhythm and no ST elevation

Caveat

Swedish registry data; residual confounding and no data on prehospital or out-of-hospital factors influencing angiography decisions

Bottom line

Context only

Learning goal

Recognise how sex-based bias may influence reperfusion decisions for women after out-of-hospital cardiac arrest.

  Ten-year German registry study modelling eCPR eligibility after OHCA in a mixed urban-rural region — of 1,696 analysed arrests, only 348 (20.5%) met local eligibility criteria at ambulance arrival and just 149 (8.8%) met the stricter modified ELSO definition, with the study also testing whether hypothetical intra-arrest transport strategies could meet a 60-minute low-flow target.
