Key result
High-risk sociodemographic characteristics (e.g., uninsured, low-income, non-US-born) were associated with a 6-fold higher odds of being unaware of any MI symptoms (OR 6.34; 95% CI 3.92-10.26; P<.001).
Why the study?
Prompt recognition of myocardial infarction symptoms is critical for timely emergency care, but patients continue to have delayed hospital presentations.
Cross-Sectional (n=25,271)
Odds Ratio: 6.34 (95% CI 3.92–10.26)
p-value: p=<.001
A significant proportion of US adults, particularly within specific sociodemographic subgroups such as those with lower education or born outside the US, remain unaware of common myocardial infarction symptoms and the need to call emergency medical services.
No takes yet. Share an insight, caveat, or question.
May warrant targeted MI awareness efforts in high-risk groups; leaves open effects on care-seeking or outcomes.
Mahajan et al. (2019) conducted a cross-sectional in Myocardial infarction symptom awareness (n=25,271). High-risk sociodemographic characteristics (non-US-born, uninsured, low-income, lower education, non-Hispanic black or Hispanic) vs. Individuals without these characteristics was evaluated on Unawareness of any myocardial infarction symptoms (OR 6.34, 95% CI 3.92-10.26, p=<.001). High-risk sociodemographic characteristics (e.g., uninsured, low-income, non-US-born) were associated with a 6-fold higher odds of being unaware of any MI symptoms (OR 6.34; 95% CI 3.92-10.26; P<.001).
