Women suffering from cardiac issues in public may not be getting the help they need.

According to a study by the American Heart Association, women are less likely to receive CPR from bystanders and are much more likely to die afterward.

The study analyzed 19,331 cardiac events from 2011-15. In those numbers, 45 percent of men received CPR from bystanders compared to 39 percent of women. When men were released from the hospital, their odds for survival were 23 percent higher than women.

When cardiac emergencies occurred at home, 35 percent of women received CPR compared to 36 percent of men.

Audrey Blewer, the MPH who authored the study, says better education on CPR could alleviate the disparity.

"Ultimately this highlights a key knowledge gap in resuscitation science, that we need to characterize the bystander to better understand the barriers and biases to CPR delivery. From there this can help inform public messaging and public CPR training,” Blewer said in a release posted to the AHA's website.
