Body mass index and outcome of out-of-hospital cardiac arrest patients not treated by targeted temperature management.

Background: Obesity has been demonstrated to increase the risk of out-of-hospital cardiac arrest (OHCA) and may influence the quality and effectiveness of cardiopulmonary resuscitation. Our aim was to investigate the association between body mass index (BMI) and the outcome of OHCA victims not treated by targeted temperature management.

Methods: This was a prospective observational study of OHCA patients.
