One-Hour heart attack test could save lives and slash ER wait times

NCT ID NCT05649384

First seen Jun 24, 2026 · Last updated Jun 24, 2026

Summary

This study compares two blood test schedules for diagnosing heart attacks in the emergency room: the standard 3-hour test and a newer 1-hour test. Over 64,000 adults with chest pain will be enrolled to see if the faster test is just as safe and accurate. If it works, patients could get diagnosed and treated much sooner.

High-sensitivity cardiac troponin blood test

What this could lead to

If successful, this could make heart attack diagnosis faster and safer, reducing ER wait times and improving patient outcomes.

What could go wrong

The trial is observational, not a controlled experiment, so results may not prove cause and effect. The faster test might miss some heart attacks in real-world use.
