• Cardiac Arrest
• Precipitating factors
• Life change event

Objective: Wehypothesized that major psychological stress can be a risk factor for cardiac arrest and that effects are modified by elapsed time from specific stressful events.
Methods: Case-control studywas conducted using database for cardiac arrest and emergency department (ED) visiting. Cases included adult patients with cardiac arrest with presumed cardiac etiology. Controls were matched with sex and age and visiting day from unintentional injured patients in same ED. The occurrence of 9 major life events (MLEs) such as a divorce within 1 year was used as a proxy measure of major psychological stress. A multivariable conditional logistic regression conducted to estimate the effect of MLEs on the risk of cardiac arrest according to the elapsed time from the MLEs.
Results: A total of 95 patientswith cardiac arrest and 95 controlswere assessed. Inthe casegroup, a total of 58MLEs occurred, while 33MLEs occurred in the control group during the same period. Recent MLEs were associated with a higher risk of sudden cardiac arrest (AOR 2.26 [95% CI: 1.01-5.03]). The AORs of cardiac arrest were 4.65 (95% CI, 1.38-15.67) and 7.02 (95% CI, 2.03-24.48) among participants experiencingMLEswithin the last 0-3months and those experiencing MLEs within the last 0-6 months, respectively. Cardiac arrest and MLEs in participants experiencing MLEs between 7 and 12 months prior showed no association (AOR 4.76 [95% CI, 0.97-18.36]).
Conclusions: MLEs were associated with cardiac arrest occurrence, and the effect wasmodified by the elapsed time from the MLEs.
