Key result
Patients with pericardial effusion and cardiac tamponade had a significantly higher mortality rate (42.0%) compared to those without tamponade (23.2%, p=0.001).
Why the study?
With advances in medicine and improvement in the social context, the most frequent etiological causes of pericardial effusion and cardiac tamponade have changed.
Cohort (n=254)
No
In a contemporary cohort, idiopathic causes remain the most common etiology for pericardial effusion without tamponade, whereas post-surgical and post-procedural causes are the most frequent in patients presenting with cardiac tamponade, which is associated with significantly higher mortality.
Tamponade in effusion flags higher-risk patients for close monitoring; observational data leaves open etiology-specific interventions.

Queiroz et al. (2021) conducted a cohort in Pericardial effusion with or without cardiac tamponade (n=254). Cardiac tamponade vs. No cardiac tamponade was evaluated on Mortality (p=0.001). Patients with pericardial effusion and cardiac tamponade had a significantly higher mortality rate (42.0%) compared to those without tamponade (23.2%, p=0.001).
