A few months ago, a thread went viral on Twitter as a woman offered a similar warning after experiencing a cardiac arrest.

“I want to warn women our heart attacks feel different,” she wrote. “Last Sunday I had a heart attack. I had a 95% block in my left anterior descending artery. I’m alive because I called 911.

“I never had chest pain. It wasn’t what you read in pamphlets. I had it off and on for weeks.”

This isn’t the first time that research has pointed to these medical inequalities for women. A 2017 study found only 39% of women suffering cardiac arrest in a public place were given CPR versus 45% of men, and men were 23% more likely to survive an attack. And in February, the American Heart Association published research into why: apparently, and shockingly, members of the general public perceive fears about inappropriate touching, accusations of sexual assault, and fear of causing injury as inhibiting bystander CPR for women.

This is why women are less likely to be resuscitated than men
