We evaluated the characteristics, management, and outcomes of patients hospitalized with PE with or without PFO.  \nMethods: Using the National Inpatient Sample database, adult patients admitted with acute PE between 2016 and 2020 were identified via ICD-10 codes. Patients were grouped based on whether they had concomitant PFO. Clinical characteristics, advanced therapies, and in-hospital outcomes were compared between patients with and without PFO. Multivariable logistic regression analyses were adjusted for demographics and comorbidities, with outcomes reported as adjusted odds ratios (aORs) and 95% confidence intervals (CIs) .  \nResults: We identified 903,230 adult patients hospitalized with acute PE, among whom 4,860 (0.54%) had a PFO. Patients with concomitant PE and PFO were younger (59.4 ± 15.9 vs. 63 ± 16.5 years, P \u003C 0.001) and presented with more severe clinical features, including higher rates of saddle PE (17.7% vs. 9%, P \u003C 0.001) and cor pulmonale (17.9% vs. 8.3%, P \u003C 0.001) .

After multivariable adjustment, PFO presence was associated with significantly increased odds of stroke (aOR 25.5, 95% CI 19.8-32.8; P \u003C 0.001) and peripheral embolism (aOR 13.7, 95% CI 10.5-18.0; P \u003C 0.001) but not increased in-hospital mortality (aOR 0.9, 95% CI 0.6-1.3; P = 0.702) .  \nConclusion: In this nationwide study, PFO in patients with acute PE was linked to greater clinical severity and more frequent advanced interventions. Prospective studies are needed to define optimal screening strategies.  \nKeywords: Pulmonary embolism; Patent foramen ovale; Stroke; Paradoxical embolism  \nIntroduction  \nPulmonary embolism (PE) is a significant cardiovascular condition associated with high morbidity, mortality, and substantial healthcare utilization [1, 2] . It represents the third most common cause of cardiovascular-related deaths, affecting hundreds of thousands of patients annually in the United States [1] . In addition to acute complications such as hemodynamic instability and death, PE can lead to long-term consequences, including chronic thromboembolic pulmonary hypertension (CTEPH) and recurrent thromboembolic events [3, 4] .
