AbstractObjectives: The HEART Pathway is a diagnostic protocol designed to identify low-risk patients with chest pain who can be safely discharged from the emergency department (ED) without hospitalization. Studies have reported a negative bias in identifying myocardial ischemia in females versus males and a different clinical pattern of cardiac ischemia across genders. This study sought to determine if the HEART Pathway recommendations are affected by negative bias in females. Materials and Methods: A retrospective cohort study was conducted in the ED of an academic tertiary medical center. Admission/discharge decisions made by physicians in male and female patients presenting with chest pain in 4/2014-7/2019 were compared with HEART Pathway protocol predictions. Probabilities were estimated with logistic regression analysis, and odds ratios and 95% confidence intervals were calculated. Results: The cohort included 772 patients, 485 male (63%) and 287 female (37%), of median age 54 years. On the basis of their presenting symptoms, 278 patients (36%) were admitted by the ED physician and 494 (64%) were discharged. Using the HEART Pathway protocol, 227 patients (29.4%) would be expected to be admitted and 545 (70.6%) discharged. The real-life admission rate was higher than possible with the HEART Protocol (p = 0.001). In a regression model, male sex was a significant factor favoring admission among the patients for whom the HEART Pathway predicted admission (p = 0.007). Conclusions: As the HEART Pathway is a validated risk-stratification tool, there is a high likelihood that serious coronary artery disease may be overlooked in women, even those who seek timely medical assistance.
