Prevalence of STOP BANG questionnaire and association with major cardiovascular events in hospitalized population: Is it enough with currently used cardiovascular risk measurements?

Abstract 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 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.
