Key result
Moderate to severe pericardial effusion complicating STEMI was associated with a 43% 30-day mortality, significantly higher than the 10% observed in patients with small effusion (P<0.001).

Moderate-severe pericardial effusion signals high 30-day mortality in STEMI; leaves open whether targeted interventions improve outcomes.

Does moderate to severe pericardial effusion increase 30-day mortality in patients with ST-elevation myocardial infarction?
Absolute Event Rate: 43% vs 10%
p-value: p=<0.001
Moderate to severe pericardial effusion complicating STEMI carries a high 30-day mortality, particularly in patients presenting with cardiac tamponade and electromechanical dissociation.
Figueras et al. (2010) conducted a cohort in ST-elevation acute myocardial infarction (n=542). Moderate to severe pericardial effusion (≥10 mm) vs. Small pericardial effusion (5 to 9 mm) or no pericardial effusion was evaluated on 30-day mortality (p=<0.001). Moderate to severe pericardial effusion complicating STEMI was associated with a 43% 30-day mortality, significantly higher than the 10% observed in patients with small effusion (P<0.001).
