Sex Differences in Patients With Cryptogenic Cerebrovascular Events Undergoing Transcatheter Closure of Patent Foramen Ovale
Bibliographic record
Abstract
Background Scarce data exist on sex differences in patients with cryptogenic cerebrovascular events undergoing patent foramen ovale (PFO) closure. This study aimed to determine the sex differences in clinical profile, procedural characteristics, and long‐term outcomes of patients with cryptogenic cerebrovascular events undergoing PFO closure. Methods and Results A retrospective cohort was used, including 1076 consecutive patients undergoing PFO closure because of a cryptogenic cerebrovascular event. Patients were divided into 2 groups: 469 (43.6%) women and 607 (56.4%) men. The median follow‐up was 3 years (interquartile range, 2–8 years). Women were younger (46±13 versus 50±12 years; P <0.01) and had a higher risk of paradoxical embolism score (6.9±1.7 versus 6.6±1.6; P <0.01). Procedural characteristics and postprocedural antithrombotic therapy were similar. At follow‐up, there were no differences in atrial fibrillation (women versus men: 0.47 versus 0.97 per 100 patient‐years; incidence rate ratio [IRR], 0.55 [95% CI, 0.27–1.11]; P =0.095; adjusted P =0.901), stroke (0.17 versus 0.07 per 100 patient‐years; IRR, 2.58 [95% CI, 0.47–14.1]; P =0.274; adjusted P =0.201), or transient ischemic attack (0.43 versus 0.18 per 100 patient‐years; IRR, 2.58 [95% CI, 0.88–7.54]; P =0.084; adjusted P =0.121); nevertheless, women exhibited a higher incidence of combined ischemic cerebrovascular events (0.61 versus 0.26 per 100 patient‐years; IRR, 2.58 [95% CI, 1.04–6.39]; P =0.041; adjusted P =0.028) and bleeding events (1.04 versus 0.45 per 100 patient‐years; IRR, 2.82 [95% CI, 1.41–5.65]; P =0.003; adjusted P =0.004). Conclusions Compared with men, women with cryptogenic cerebrovascular events undergoing PFO closure were younger and had a higher risk of paradoxical embolism score. After a median follow‐up of 3 years, there were no differences in stroke events, but women exhibited a higher rate of combined (stroke and transient ischemic attack) cerebrovascular events and bleeding complications. Additional studies are warranted to clarify sex‐related outcomes after PFO closure further.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
