Cardiovascular risk (CR) is associated with obstructive sleep apnea hypopnea syndrome (OSAHS). This association enhances the risk of major adverse cardiovascular events (MACE); nevertheless, data from hospitalized populations and interactions among these conditions remain unclear.
PURPOSE: To evaluate the risk of MACE in the population with risk of OSAHS using the STOP-BANG questionnaire.
METHODS: We performed a prospective study in an academic hospital from 2017 to 2018. Data included demography, admissions, STOP-BANG score and CR using AHA scores. The primary outcome was risk of MACE in participants with low risk of OSAHS (STOP-BANG 0-2 points), risk of OSAHS (≥3 points) and risk of moderate/severe OSAHS (≥5 points). Risk of MACE was evaluated using odds ratios (OR), and average CR was evaluated using the t-test.
RESULTS: A total of 441 participants were included. The cumulative prevalence of STOP BANG ≥3 points was 80.9%, and that of ≥5 points was 41.6%. OR of MACE ≥3 points was 3.93 (CI 2.08-7.24) (p < 0.001) compared with <3 points, and Average CR was 10.91% (SD ± 2.13) at <3 points versus 24.3% (SD ± 1.24) for ≥3 points for ≥5 points OR of MACE was 1.72 (CI 1.18-2.59) (p = 0.005) and average CR was 26.14% (SD ± 1.63). However, after multivariable analysis, gender differences and previous heart failure were independently associated to MACE.
CONCLUSION: The risk of OSAHS in the hospitalized population is high. This population has a higher risk of MACE and higher CRs than do low-risk participants. Conversely, gender and heart failure are potential cofounders.
