Abstract

Background: Timely revascularization with percutaneous coronary intervention ( PCI ) reduces death following myocardial infarction. We evaluated if a sex gap in symptom‐to‐door ( STD ), door‐to‐balloon ( DTB ), and door‐to‐ PCI time persists in contemporary patients, and its impact on mortality. Methods and Results: From 2013 to 2016 the Victorian Cardiac Outcomes Registry prospectively recruited 13 451 patients (22.5% female) from 30 centers with ST‐segment–elevation myocardial infarction ( STEMI , 47.8%) or non–ST‐segment–elevation myocardial infarction (NSTEMI) (52.2%) who underwent PCI . Adjusted log‐transformed STD and DTB time in the STEMI cohort and STD and door‐to‐ PCI time in the NSTEMI cohort were analyzed using linear regression. Logistic regression was used to determine independent predictors of 30‐day mortality. In STEMI patients, women had longer log‐ STD time (adjusted geometric mean ratio 1.20, 95% CI 1.12‐1.28, P <0.001), log‐ DTB time (adjusted geometric mean ratio 1.12, 95% CI 1.05‐1.20, P =0.001), and 30‐day mortality (9.3% versus 6.5%, P =0.005) than men. Womens’ adjusted geometric mean STD and DTB times were 28.8 and 7.7 minutes longer, respectively, than were mens’ times. Women with NSTEMI had no difference in adjusted STD , door‐to‐ PCI time, or early (<24 hours) versus late revascularization, compared with men. Female sex independently predicted a higher 30‐day mortality (odds ratio 1.67, 95% CI 1.11‐2.49, P =0.01) in STEMI but not in NSTEMI. Conclusions: Women with STEMI have significant delays in presentation and revascularization with a higher 30‐day mortality compared with men. The delay in STD time was 4‐fold the delay in DTB time. Women with NSTEMI had no delay in presentation or revascularization, with mortality comparable to men. Public awareness campaigns are needed to address women's recognition and early action for STEMI .

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
