Before a cardiac arrest, men and women have different symptoms, study finds

 This is very important information about Cardiac arrest symptoms. The article is posted here The main points are below:

Of the more than 356,000 cardiac arrests in the United States each year, 90% are fatal.

While there are some known signs of sudden cardiac arrest, it usually occurs without warning.

Researchers from the Smidt Heart Institute at Cedars-Sinai Health System have found that half of people experiencing a sudden cardiac arrest also had a telling symptom 24 hours beforehand.

Scientists also discovered those warning symptoms are different between men and women.

The scientists also found differences in the sudden cardiac arrest warning symptoms between men and women.

Researchers found that the most prominent symptom for women 24 hours before cardiac arrest was shortness of breath. For men, chest pain was the preeminent telltale symptom.

Cardiac arrest warning signs: Men vs. women

The scientists also found differences in the sudden cardiac arrest warning symptoms between men and women.

Researchers found that the most prominent symptom for women 24 hours before cardiac arrest was shortness of breath. For men, chest pain was the preeminent telltale symptom.

“There is increasing and urgent recognition of how important it is to perform clinical research that can evaluate sex differences between conditions,” Dr. Chugh said.

“For sudden cardiac arrest, there are already well-established findings that suggest different mechanisms and underpinnings of this condition between the sexes. For example, men are far more likely to suffer sudden cardiac arrest — two-thirds of victims are male — and women tend to present with this condition an average of 8-10 years later in life compared to men,” he noted.

“In advising patients, especially those who are known to have significant heart conditions, healthcare providers can make them aware that women with unexpected shortness of breath have a 3-fold higher risk of an imminent sudden cardiac arrest; and men with unexpected chest pain have a 2-fold increased risk,” he added. “In these situations, it would be prudent to seek urgent care.”
