To determine the epidemiological characteristics, temporal trends and survival outcomes of OHCAs precipitated by chemical asphyxiation. ⋯ OHCA precipitated by chemical asphyxiation is relatively infrequent and associated with poor survival outcomes.
-
To evaluate the association between bystander cardiopulmonary resuscitation (CPR), automated external defibrillator (AED) use, and survival after out-of-hospital cardiac arrest (OHCA) across the urban-rural spectrum. ⋯ Bystander CPR and AED use are associated with positive clinical outcomes after OHCA in all areas along the urban-rural spectrum.

This study investigated the changes in quality of life (QOL) after in-hospital cardiopulmonary arrest (IHCA) among survivors and examined the association between worsening QOL and 3-year all-cause mortality. ⋯ Approximately one-third of IHCA survivors experienced worsening QOL (decreased household income, unemployment, and acquired disability) at 1-year follow-up after IHCA in South Korea. Although overall worsening of QOL was not associated with 3-year all-cause mortality, acquired disability was associated with increased 3-year all-cause mortality among IHCA survivors.

Sudden arrhythmic death syndrome (SADS), defined as sudden cardiac death (SCD) with a morphologically normal heart, is an important cause of sudden death. Hypoperfusion due to cardiac arrest followed by successful cardiopulmonary resuscitation (CPR) may induce histologic changes that mimic pathologic conditions. Detailed characterisation of such features and whether they could confound SADS diagnosis are not described. ⋯ We provide a comprehensive characterisation of hypoperfusion-related changes in the heart following successful CPR with survival, which are time related. These features can lead to diagnostic confusion among pathologists but knowledge of history of resuscitation with survival should help with general and expert pathology assessment and improve SADS diagnostic yield, prompting genetic screening of decedents' relatives.

We investigated the impact of healthy lifestyle factors and cardiovascular comorbidities for sudden cardiac arrest. ⋯ The increased risk of sudden cardiac arrest by cardiovascular comorbidities could be significantly reduced with healthy lifestyle factors.
