Abstract
Introduction
Obstructive sleep apnea (OSA) increases cardiovascular disease risk through systemic inflammation, particularly through elevated C-reactive protein (CRP). This study investigated whether CRP stratification predicts mortality and cardiovascular events in OSA patients.
Methods
We conducted a retrospective cohort analysis using the TriNetX Research Network, encompassing electronic health records from 130 healthcare institutions. Adults (ages 18-90 years) with OSA were stratified by CRP concentration: elevated (≥ 3.0 mg/L) versus low (≤ 2.9 mg/L). After propensity score matching for demographics and comorbidities, 240,727 participants per cohort were followed for five years. Primary outcome was all-cause mortality; secondary outcomes included cardiovascular events, arrhythmias, and acute kidney injury.
