First seen Feb 02, 2026 · Last updated Jun 17, 2026 · Updated 28 times

Summary

This study looks at whether certain common medications, known as QT-prolonging drugs, actually cause serious heart problems in hospitalized adults. Researchers will analyze data from over 990,000 patients 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 to reduce unnecessary medication alerts that can disrupt care.
