INTCAR demonstrates gender differences in survival after cardiac arrest

In a cohort of 1667 out of hospital cardiac arrest survivors, Viktor Karlsson and colleagues found men were more likely to receive bystander cardiopulmonary resuscitation, have an initial shockable rhythm and to have a presumed cardiac cause of arrest. At hospital discharge, men had a higher survival rate (52% vs. 38%, P < 0.001) and more often a good neurological outcome (43% vs. 32%, P < 0.001) in the univariate analysis. When adjusting for baseline characteristics, male gender was associated with improved survival (OR 1.34, 95% CI 1.01 to 1.78).  Read more at: Crit Care 2015;19:182.
