Abstract 13452: Sex Differences in Presentation, Management, and Outcomes Among Patients Hospitalized With Acute Pulmonary Embolism
Introduction: The presence of gender disparities in cardiovascular disease has been well-described, but there is a paucity of data regarding the impact of gender on the presentation, management and outcomes of acute pulmonary embolism (PE). Hypothesis: We hypothesized that there are no gender-based differences in PE management or outcomes. Methods: We identified all patients admitted to our institution with acute PE from 8/1/2012-7/1/2018. We stratified presenting characteristics, management and outcomes between women and men. Outcomes included major bleeding, survival, 90-day readmission, and 90-day recurrent venous thromboembolism (VTE). Inverse probability of treatment weighting was used to evaluate the independent association between sex and in-hospital and short-term outcomes. Results: The study included 2031 patients with PE, 53.2% of whom were women. Women had a higher mean age (63.8 years vs 62.3 years, P=0.04). PE severity was similar between women and men (massive: 4.9% vs 3.6%; submassive: 43.9% vs 41.8%; P=0.19), but women were more likely to present with dyspnea (59.8% vs 52.0%, P<0.001) and had higher median NT-pro-BNP levels (605 pg/mL [IQR 143-2582] vs 319 pg/mL [IQR 82-1576], P<0.001). Although the comorbidity burden was similar, women were less likely to have a history of PE (19.3% vs 24.2%, P=0.01), smoking (43.1% vs 53.3%, P<0.001), or myocardial infarction (6.6% vs 9.7%, P=0.01). In unadjusted analyses, women were less likely to survive to discharge (92.4% vs 94.7%, P=0.04), but after adjustment, there was no gender-based survival difference. There were also no gender differences in PE-related diagnostic studies, use of advanced therapies, or other short-term outcomes, before and after adjustment (p>0.05 for all) (Fig 1). Conclusions: In this large PE cohort from a tertiary care institution, women had different comorbidity profiles and PE presentations than men. Despite this, there were no gender disparities in PE management or outcomes.
