Chest pain in acute pulmonary embolism patients independently predicted a lower risk of adverse outcomes (OR 0.35) and in-hospital mortality (OR 0.31) irrespective of sex.
Does the presence of chest pain at presentation predict in-hospital adverse outcomes and mortality in patients with acute pulmonary embolism?
In patients with acute pulmonary embolism, the presence of chest pain at presentation is a favorable prognostic marker associated with significantly lower in-hospital mortality and adverse outcomes.
Background: While previous studies indicate an association between chest pain and favorable clinical outcomes in patients with pulmonary embolism (PE), the extent and underlying mechanisms of this effect remain inadequately defined. Methods: We investigated the prognostic value of chest pain with regard to in-hospital adverse outcomes and the association of chest pain with age and sex in consecutive patients with confirmed PE enrolled in a single-center registry between 2008 and 2019. Results: Of 858 patients (52% female) included in this study, 435 (51%) had chest pain at presentation. Chest pain was more prevalent in younger individuals aged 18–34 years (74%) compared to patients >34 years (46%). The prevalence of coronary artery disease (CAD) was similar in patients with and without chest pain (17.0% vs. 16.1%). Chest pain patients less frequently presented with elevated troponin levels (p < 0.001) or signs of right heart strain (RHS; p = 0.007) but more frequently exhibited imaging signs of pulmonary infarction (p = 0.001). Chest pain was associated with lower risk of adverse outcome (OR 0.35 95% CI: 0.19–0.65) and in-hospital mortality (OR 0.31 95% CI: 0.13–0.74). Multivariable models confirmed a prognostic effect independent of sex, comorbidities and results of risk stratification algorithms. Conclusions: In acute PE, chest pain is a favorable prognostic marker irrespective of sex. Chest pain patients are less likely to suffer from myocardial ischemia or show signs of RHS but more frequently show imaging signs of pulmonary infarction, suggesting pleuritic irritation rather than myocardial ischemia as the likely cause of pain.
Frumkin et al. (2026) studied this question. Chest pain in acute pulmonary embolism patients independently predicted a lower risk of adverse outcomes (OR 0.35) and in-hospital mortality (OR 0.31) irrespective of sex.
