Sleep apnea study tracks heart risks years later
NCT ID NCT04704401
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study contacted 321 people with sleep apnea who were part of earlier research to see what health problems they had over time. Researchers asked about heart issues, diabetes, cancer, and deaths. They also looked at whether using a CPAP machine affected these outcomes. The goal was to gather information, not to test a new treatment.
