Longitudinal changes of obstructive sleep apnea and its impact on cardiovascular outcomes: Results from the Sleep Heart Health Study

Key Points

The study aims to investigate how changes in obstructive sleep apnea (OSA) affect cardiovascular outcomes over time, focusing on gender differences.
Longitudinal analysis of sleep data from participants in the Sleep Heart Health Study.
Assessment of apnea-hypopnea index (AHI) to determine the severity of OSA.
Comparison of cardiovascular outcomes in men and women with varying AHI levels.
Increased AHI correlates with heightened cardiovascular risk.
A reduction in AHI does not guarantee a decrease in cardiovascular risk, especially in men.
No significant association was found between AHI changes and cardiovascular outcomes in women.

Abstract

OSA course showed dynamic changes. Increased AHI was associated with higher cardiovascular risk, and a reduction in AHI in patients with OSA may not signify complete remission of cardiovascular risk, particularly among men. No such association was observed in women.
