Very Long Apneas during Prone Position in a Lean Patient with Coronary Artery Disease: Implications for the Cardiovascular Risk

Introduction

Obstructive sleep apnea (OSA) is a common condition characterized by recurrent upper airway obstructions during sleep, promoting intermittent hypoxia and sleep fragmentation. Traditional risk factors for OSA include male gender and obesity. Overall, patients with severe OSA presented longer events and more severe hypoxemia. Supine sleep is consistently associated with more severe OSA rates in adults. However, the relationship between OSA indices and prone position is inconsistent. Here, we reported a very peculiar presentation of OSA characterized by very long respiratory events in a prone position in a lean female patient with a history of high blood pressure, diabetes mellitus, chronic kidney disease under dialysis therapy and a recent diagnosis of coronary artery disease (CAD).
