Key result
In patients with NSTEMI, presentation without chest pain was associated with a significantly higher risk of one-year mortality (adjusted OR 5.37) compared to presentation with chest pain.
Why the study?
Previous studies discussed acute myocardial infarction patients without chest pain, but had not focused on non-ST-elevation myocardial infarction.
Does presentation without chest pain worsen in-hospital and one-year mortality in patients with NSTEMI?
Cohort (n=194)
Does presentation without chest pain worsen in-hospital and one-year mortality in patients with NSTEMI?
Odds Ratio: 5.37
NSTEMI patients presenting without chest pain have a significantly higher risk of in-hospital and one-year mortality, highlighting the need for high clinical suspicion and prompt management in atypical presentations.
Atypical NSTEMI presentation may signal higher mortality risk; observational data leave open causality and require prospective validation.

Chien et al. (2019) conducted a cohort in Non-ST-elevation myocardial infarction (NSTEMI) (n=194). Absence of chest pain vs. Presence of chest pain was evaluated on One-year mortality (OR 5.37). In patients with NSTEMI, presentation without chest pain was associated with a significantly higher risk of one-year mortality (adjusted OR 5.37) compared to presentation with chest pain.
