Study: Sudden cardiac arrest comes with warning signs

AUSTIN (KXAN)- Often times we hear how “cardiac arrest” hits out of nowhere, but new research reveals about half of patients feel symptoms way before their attack.

Physicians at Cedar-Sinai Medical Center in Los Angeles and Oregon Health Sciences Center in Portland, Oregon looked at medical charts, EMS data and other information surrounding the episode in 839 patients who had sudden cardiac death. They wanted to see if patients had any warning signs 4 weeks prior to the episodes and also see if responding to these symptoms resulted in survival from cardiac arrest.

Researchers found 51 percent had warning signs of chest pain and dyspnea.

In most patients who had initial symptoms, 81 percent had a recurrence of symptoms 24 hours before they suffered cardiac arrest.
