These are the warning signs prior to a heart attack


New York: For women, the most prominent symptom of impending sudden cardiac arrest is difficulty breathing, while men may experience chest pain, scientists led by an eminent health expert of Indian origin have revealed.

The study from the Smidt Heart Institute at Cedars-Sinai Medical Center in Los Angeles, led by sudden cardiac arrest expert Sumeet Chugh, found that 50 percent of people experienced warning signs before their cardiac arrest.

The team led by Chugh found that this warning symptom was different for women than for men, according to the study published in the peer-reviewed journal Lancet Digital Health.

Smaller subgroups of both sexes experienced palpitations, seizure-like activity, and flu-like symptoms.

“Leveraging warning symptoms to effectively triage those who need to make a 999 call could lead to early intervention and prevention of imminent death,” Chugh said.

“Our findings could lead to a new paradigm for the prevention of sudden cardiac death,” he added.

For this study, researchers used two established and ongoing community studies in the US, each developed by Chugh.

Both studies provide Cedars-Sinai researchers with unique community-based data to establish how to best predict sudden cardiac arrest.

“It takes a village to do this work. We started the SUDS study 22 years ago and the PRESTO study eight years ago. “These groups have provided invaluable lessons along the way,” Chugh said.

In both studies, Smidt Heart Institute researchers assessed the prevalence of individual symptoms and symptom clusters before sudden cardiac arrest and then compared these findings to control groups who also sought emergency medical care.

“Next, we will complement these key sex-specific warning symptoms with additional features, such as clinical profiles and biometric measures, to improve the prediction of sudden cardiac arrest,” Chugh added.
