Obstructive Sleep Apnea and Cardiovascular Events Clinical correlations

Abstract

Obstructive sleep apnea (OSA) has been described as an independent predictor of mortality and cardiovascular morbidity, and several studies link OAS and atrial fibrillation, although further investigations are needed to fully understand the common physiological mechanisms. The aim of the study was to identify the cardiovascular risk and events of a population diagnosed with OAS and to discover the predisposing factors of the appearance of AF in these patients. Demographic, clinical, laboratory and echocardiographic data were taken from 101 patients previously diagnosed with OSA and admitted to our cardiovascular unit. In a population with cardiovascular risk factors and cerebrovascular events, the prevalence of atrial fibrillation was 63.7%, whereas ventricular arrythmias occurred in 31.4%. The only prediction factor for AF in OSA population was the history of myocardial infarction; other predisposing factors take account for a small number of cases. The presence of a significant association between OSA and markers of cardiovascular disease would warrant the development of a strategy to consider more aggressive therapeutic approaches.

“…Lipid status of patients included in the study Fig.5. Weighted status of patients included in the study improves lipid profile, glucose tolerance and insulin sensitivity and also improves sleep apnea [23][24][25]. Interestingly, overweight people defined by a body mass index between 25 and 30 Kg/m 2 have a lower cardiovascular and general mortality than those with normal weight.…”
