Heart ultrasound wave may speed up heart attack diagnosis in ER

This study looked at whether a specific heart ultrasound measurement, called the S' wave, can help emergency doctors quickly identify acute coronary syndrome (a heart attack or unstable angina) in adults with chest pain. Researchers studied 66 patients who came to the emergency room with chest pain but did not have clear signs of a major heart attack on their initial ECG. The goal was to see how accurate the S' wave test is compared to the final diagnosis made after three months of follow-up.
