ER heart scan may catch attacks earlier

This study tested whether a simple bedside heart ultrasound measurement, called the S' wave, can help emergency doctors quickly identify acute coronary syndrome (heart attack or unstable angina) in patients with chest pain. Researchers enrolled 66 adults who came to the ER with chest pain but no clear signs of a major heart attack on their initial ECG. They compared the S' wave results with the final diagnosis made after 3 months of follow-up. The goal is to see if this quick test can improve early detection and speed up life-saving care.
