Emergency Department Blood Test May Help Rule Out Heart Attack Within 15 Minutes

Bottom Line: A new, quick and accurate, bedside blood test done in an emergency department could help reduce the time it takes to rule out heart attacks. A preliminary study suggests a 15-minute blood test in the emergency department to measure a protein in the blood (cardiac troponin) may have similar ability to rule out a heart attack as blood tests that take longer to be measured in a laboratory. The analysis in this observational study at a single regional emergency department included about 350 patients with symptoms of a heart attack. Confirmation in larger studies is needed.
