Obstructive sleep apnoea in patients with atrial fibrillation: prevalence, determinants and clinical characteristics of patients in Polish population

Abstract

OSA is highly prevalent in patients with AF in the Polish population, and affects approximately half of the patients. OSA patients are more likely to be older, have higher BMI, and greater waist and neck circumference. Persistent AF is the most common form of the arrhythmia in patients with OSA, while patients without OSA are more likely to have paroxysmal AF.

Which components of the CHA2DS2-VASc score are the most important in obstructive sleep apnea patients with atrial fibrillation?

“…The methodology of the present study was described in detail previously [6][7][8]. The study included 266 consecutive patients with a diagnosed atrial fibrillation in whom there was a successful diagnostic test for OSA performed, and who were screened for the components of the CHADS 2 and CHA 2 DS 2 -VASc scores.…”

Can thromboembolic risk be associated with erectile dysfunction in atrial fibrillation patients?

“…In AF patients, it was found that most of the previously described risk factors of the vascular dysfunction are elevated [10][11][12]. AF is also strongly associated with elevated thromboembolic risk.…”

Is obstructive sleep apnea associated with the risk of ischemic stroke in patients with atrial fibrillation?

“…We have previously shown that in AF patients qualified for ablation (which account for a relatively young and healthy subgroup of AF population) the prevalence of all OSA is 45.49% [9]. Our study protocol required sleep-study screening in consecutive patients, regardless of their symptoms and therefore showed reliable data on the sleep disordered breathing prevalence.…”
