Key result
Intermittent chest pain in AMI linked to ~139-minute longer pre-hospital delay vs persistent pain.
Why the study?
Atypical symptoms in AMI patients are linked to care-seeking delays, but the impact of typical chest pain characteristics on pre-hospital delay is underexplored.
Does intermittent chest pain compared to persistent chest pain increase pre-hospital delay time in patients with acute myocardial infarction?
Population
257 AMI patients with chest pain from the MEDEA FAR-EAST study in Shanghai
Comparison
Intermittent (including fluctuating) chest pain vs persistent chest pain
Design
Multicenter cross-sectional study

Intermittent pain signals risk for prolonged AMI delays; leaves open whether education on fluctuating symptoms shortens decision time.
Cross-Sectional (n=257)
Yes
Does intermittent chest pain compared to persistent chest pain increase pre-hospital delay time in patients with acute myocardial infarction?
Absolute Event Rate: 248.5% vs 110%
p-value: p=<0.001
Intermittent chest pain in AMI patients is an independent predictor of longer pre-hospital delays, highlighting the need for better patient education regarding fluctuating symptoms.
Zhang et al. (2022) conducted a cross-sectional in Acute myocardial infarction (n=257). Intermittent chest pain vs. Persistent chest pain was evaluated on Pre-hospital delay time (PHT) in minutes (p=<0.001). In patients with acute myocardial infarction, intermittent chest pain was associated with a significantly longer median pre-hospital delay time compared to persistent chest pain (248.5 vs 110.0 minutes).
