Key result
Novel ABPM-based score identifies moderate-to-severe OSA in hypertensive patients with ~0.80 AUC.
Why the study?
Obstructive sleep apnea is frequent and underdiagnosed in hypertensive individuals who experience cardiovascular events, necessitating better screening methods.
Does a scoring system based on ambulatory blood pressure monitoring and clinical variables identify moderate to severe obstructive sleep apnea in hypertensive patients?
Population
105 ABPM-confirmed hypertensive patients who snored
Comparison
Scoring system combining clinical and ABPM variables vs no screening model
Design
Observational study with multivariate logistic regression analysis

May aid OSA screening in hypertensives via ABPM; leaves open prospective validation before clinical adoption.

Does a scoring system based on ambulatory blood pressure monitoring and clinical variables identify moderate to severe obstructive sleep apnea in hypertensive patients?
Effect estimate: AUC 0.804
A validated scoring system incorporating ambulatory blood pressure monitoring variables and clinical characteristics can effectively identify moderate to severe obstructive sleep apnea in untreated hypertensive patients who snore.
Torres et al. (2015) conducted an observational in Obstructive Sleep Apnea in Hypertension (n=105). Ambulatory blood pressure monitoring (ABPM) and clinical variables model was evaluated on Identification of moderate to severe OSA (apnea-hypopnea index ≥15) (AUC 0.804). A scoring model incorporating ambulatory blood pressure monitoring variables, sex, and obesity identified moderate to severe obstructive sleep apnea in hypertensive patients with an AUC of 0.804.
