Association Between Hypothermia/Ischemia Ratio and Functional Outcome From Out-of-Hospital Cardiac Arrest

Association Between Hypothermia/Ischemia Ratio and Functional Outcome From Out-of-Hospital Cardiac Arrest

Although a larger hypothermia/ischemia ratio was associated with good functional outcome after out-of-hospital cardiac arrest in this cohort, this association is primarily driven by duration of time to return of spontaneous circulation.

Tailoring duration of targeted temperature management based on duration of time to return of spontaneous circulation or patient characteristics requires prospective study.

The primary outcome was hospital survival with good functional status (modified Rankin Score, 0–3) at hospital discharge. We fitted logistic regression models to estimate the association between hypothermia/ischemia ratio and the primary outcome, adjusting for demographics, arrest characteristics, and Resuscitation Outcomes Consortium enrolling site.

A total of 3,429 patients were eligible for inclusion, of whom 36.2% were discharged with good functional outcome.

Patients had a mean age of 62.0 years (sd, 15.8), with 69.7% male, and 58.0% receiving lay-rescuer cardiopulmonary resuscitation.
