NCT ID NCT07374263

First seen Feb 02, 2026 · Last updated May 01, 2026 · Updated 17 times

Summary

This study looks at whether certain common medications, known to affect the heart's electrical activity (QT interval), actually lead to serious heart problems like dangerous rhythms or sudden death. Researchers will analyze data from nearly a million hospitalized adults to compare those who had heart events with those who did not. The goal is to find out which patients are truly at risk and improve medication safety alerts that currently cause frequent disruptions.
