UNDERDIAGNOSED OBSTRUCTIVE SLEEP APNEA USING RESPIRATORY POLYGRAPHY IN HOSPITALIZED HEART FAILURE PATIENTS AT TERTIARY HOSPITAL IN LIMA-PERU (#22215)
Objetivos
This study aimed to determine the frequency of OSA in hospitalized HF patients using respiratory polygraphy (RP) (Sleep Study Type III).
Materiales y Métodos
A cross-sectional study was conducted in a tertiary hospital in Peru. We included patients >18 years, with exacerbated HF, and STOP-BANG ≥ 3. Enrolled patients underwent overnight RP using ApneaLink Air. Data collected included clinical parameters, Epworth Sleepiness Scale, and echocardiography results. Statistical analysis was carried out using R Studio.
Resultados
From 46 enrolled patients, 39 underwent successful RP; 84.61% were diagnosed with OSA. Patients exhibited a mean Apnea-Hypopnea Index (AHI) of 14.41 ± 10.08/h with mild (51.28%), moderate (25.64%), and severe (7.69%) cases. Symptoms associated with OSA included lack of restorative sleep and concentration problems. RP data showed a mean minimum SpO2% of 76.85 ± 9.99 % and an Oxygen Desaturation Index (ODI) of 20.01 ± 10.66. Echocardiography revealed predominantly preserved Left Ventricular Ejection Fraction (LVEF) (92.85%). Correlation analysis indicated a strong positive correlation association between AHI and ODI (r = 0.73, p < 0.001) and a moderate negative correlation between AHI and LVEF (r=- 0.64, p= 0.056).
Conclusiones
This study highlights a high frequency of OSA among HF inpatients in our institution, emphasizing its relation with symptoms and cardiovascular parameters. This proves the importance of high suspicion, screening, and diagnosis of OSA in exacerbated HF patients.
