Researchers from Cedars-Sinai’s Smidt Heart Institute are making strides in predicting sudden cardiac arrest through a study in The Lancet Digital Health journal. They found that warning signs vary between men and women, with women experiencing shortness of breath as the primary symptom, while men typically experience chest pain. Smaller groups of both genders may also have symptoms like palpitations, seizures, or flu-like sensations.
Sudden cardiac arrest claims 90% of lives affected, emphasising the urgent need for better prediction and prevention. Identifying these symptoms early could lead to prompt intervention and prevention, potentially revolutionising approaches to preventing sudden cardiac death.
The study used data from two ongoing community-based studies, the Prediction of Sudden Death in Multi-Ethnic Communities (PRESTO) Study and the Oregon Sudden Unexpected Death Study (SUDS), to determine the most effective way to predict sudden cardiac arrest.

Dr. Chugh, the study’s senior author, stressed the collaborative effort of this work, highlighting the invaluable contributions of first responders, medical examiners, and community hospitals.
The research evaluated the prevalence of specific symptoms before sudden cardiac arrest and compared these findings with control groups seeking emergency medical care. Results showed that 50% of individuals who experienced sudden cardiac arrest had at least one telltale symptom 24 hours before the event, according to the Ventura-based study.
This community-based approach is groundbreaking and sets the stage for further studies that will integrate these key sex-specific warning symptoms with additional clinical and biometric factors for enhanced prediction of imminent sudden cardiac arrest.
