  • Title: Obstructive sleep apnea: a risk factor for cardiovascular disease.
    Author: Reishtein JL.
    Journal: J Cardiovasc Nurs; 2011; 26(2):106-16. PubMed ID: 21076317.
    Abstract:
    Obstructive sleep apnea (OSA) is a condition in which the upper airway becomes constricted or occluded during sleep, leading to decreased or absent airflow, hypoxia, and sympathetic activation. This chain of events, occurring dozens of times an hour, can contribute to the development of hypertension, coronary artery disease, heart failure, and stroke. This article discusses the epidemiology of comorbid OSA and cardiovascular disease, the pathophysiology of OSA, how it acts as a risk factor for cardiovascular problems, and how appropriate treatment of OSA ameliorates the consequences. The importance of having a high suspicion for OSA in people with risk factors (including obesity, middle age, male or postmenopausal female) or symptoms (snoring, excessive daytime sleepiness, difficulty concentrating) is pointed out. The article concludes with clinical and research implications.
