PARIS, Sept 18, 2023 (BSS/AFP) - Bystanders are less likely to give life-
saving CPR to women having a cardiac arrest in public than men, leading to
more women dying from the common health emergency, researchers said Monday.

Cardiopulmonary resuscitation (CPR) combines mouth-to-mouth breathing and
chest compressions to pump blood to the brain of people whose hearts have
stopped beating, potentially staving off death until medical help arrives.

In research to be presented at a medical conference in Spain this week, but
which has not yet been peer-reviewed, a team of Canadian doctors sought to
understand how bystanders administer the procedure differently to men and
women.

They looked at records of cardiac arrests that took place outside of hospital
in the United States and Canada between 2005 and 2015, which included nearly
40,000 patients.

Overall, 54 percent of the patients received CPR from a bystander, the
research said.

For cardiac arrests in a public place, such as in the street, 61 percent of
women were given CPR by a bystander -- compared to 68 percent of men.

Alexis Cournoyer, an emergency physician at the Hopital du Sacre-Coeur de
Montreal who conducted the research, told AFP that this gap "increases
women's mortality following a cardiac arrest -- that's for sure".

Cardiac arrests are a leading cause of death, with more than 350,000
occurring in the US alone every year, according to the American Heart
Association.

Only around 10 percent of people who have a sudden cardiac arrest outside of
a hospital survive, research has shown.

- 'Barrier of recognition' -

The researchers sought to find a reason for the gender gap.

One theory was that bystanders in public could be uncomfortable touching a
women's breast without consent, Cournoyer said.

The researchers looked into whether age could play a role, he added.

But it did not -- women were less likely to receive CPR than men from a
bystander regardless of their age, the data showed.

Cournoyer said another possibility was a "barrier of recognition" for women
having a cardiac arrest, which is often represented as something that happens
only to men.

Before a cardiac arrest, men are more likely to have chest pain -- a commonly
depicted symptom in media -- while women are more likely to experience
shortness of breath, according to a study published last month in Lancet
Digital Health.

Cournoyer said further research was required to shed light on the gap between
men and women, in particular involving data on the gender of those performing
CPR.

The research, which the team plans to publish in a peer-reviewed journal,
will be presented at the European Emergency Medicine Congress 2023 in
Barcelona.
