Among 933 out-of-hospital cardiac arrest patients, 3.4% survived to hospital discharge, and autopsy findings revealed a cardiac etiology in 92.1% of cases with an uncertain cause of death.

In out-of-hospital cardiac arrests with uncertain cause of death, cardiac etiology predominates on autopsy.
Background: Sudden cardiac arrest with or without sudden cardiac death (SCD) represents a heterogeneous spectrum of underlying etiology but is often a catastrophic event. Despite improvements in pre-hospital response and post-resuscitation care, outcomes remain grim. Thus, we aim to evaluate the predictors of survival in out-of-hospital cardiac arrests (OHCAs) and describe autopsy findings of those with the uncertain cause of death (COD). Methods: This is a subgroup analysis of the Singapore cohort from the Pan Asian Resuscitation Outcome Study which studied 933 OHCAs admitted to two Singapore tertiary hospitals from April 2010 to May 2012. Results: = 6) rounding out the top three causes of demise. Conclusion: OHCA remains a clinical presentation that portends a poor prognosis. Of those with uncertain COD, cardiac etiology appears to predominate from autopsy study. Identification of prognostic factors will play an important role in improving individual-level and systemic-level variables to further optimize outcomes.
Li et al. (2022) conducted an observational in Out-of-hospital cardiac arrest (OHCA) (n=933). Out-of-hospital cardiac arrest (OHCA) was evaluated on Survival to discharge. Among 933 out-of-hospital cardiac arrest patients, 3.4% survived to hospital discharge, and autopsy findings revealed a cardiac etiology in 92.1% of cases with an uncertain cause of death.
