Cluster analysis of clinical phenotypic heterogeneity in obstructive sleep apnea assessed using photoplethysmography.

Sleep medicine - 1 Feb 2023

Abstract excerpt

BACKGROUND: We evaluated heterogeneity in clinical phenotypes among patients with obstructive sleep apnea syndrome (OSAHS) using photoplethysmography (PPG) in cluster analysis. METHODS: All enrolled patients underwent polysomnography (PSG) monitoring while wearing a PPG device. Pulse wave signals were recorded with a modified pulse oximetry probe in the PPG device. The pulse wave-derived cardiac risk composite...
