Abstract
Atrial fibrillation is the most common sustained arrhythmias.Recently there has been evidence of higher prevalence of atrial fibrillation in obstructive sleep apnea patients compared to the general population. The aim of this study was to find the prevalence of atrial fibrillation in patients of obstructive sleep apnea in a tertiary care center. This descriptive cross-sectional study was done in Om Hospital and Research Centre from January 2016 to 2018 March after ethical clearance. Convenience sampling was done. Data was collected and entry was done in microsoft excel, point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. The prevalence of atrial fibrillation in patients with obstructive sleep apnea is 7 (10.44%) at 95% Confidence Interval (6.70-14.17%). Apnoea-Hypopnoea Index of more than 30was present in 3 (42.8%) patients of atrial fibrillation. Atrial fibrillation was seen highest, 3 (42.8%) in patients with BMI more than 30 and lowest, 1 (14.28%) patients with BMI less than 23.5. Prevalence of atrial fibrillation was seen 5 (71.4%) in male patients and 2 (28.57%) in female patients. Sixty seven (75.28%) patients had obstructive sleep apnea in which male patients was predominant 48 (71.64%). Prevalence ofatrial fibrillation in patients of obstructive sleep apnea was found to higher than the similar studies done. It is important to obtain detail cardiac history in any patients with obstructive sleep apnea and look for arrhythmias speciallyatrial fibrillation.
Highlights
Atrial fibrillation is the most common sustained arrhythmias.Recently there has been evidence of higher prevalence of atrial fibrillation in obstructive sleep apnea patients compared to the general population
Study population were the patients with obstructive sleep apnea who have been diagnosed with the help of polysomnography
Atrial fibrillation were seen only in Obstructive sleep apnea (OSA) patients in our study.Stop Bang questionnaire were used to evaluate the probability of having obstructive sleep apnea along with detailed medical history and clinical examination
Summary
Atrial fibrillation is the most common sustained arrhythmias.Recently there has been evidence of higher prevalence of atrial fibrillation in obstructive sleep apnea patients compared to the general population. The aim of this study was to find the prevalence of atrial fibrillation in patients of obstructive sleep apnea in a tertiary care center. Obstructive sleep apnea (OSA) is a common breathing disorder characterized by recurrent episodes of airway collapse resulting in occlusion of airflow during sleep.[1] OSA affects upto 25% of middle aged adults.[2] OSA is a important health problem with a high prevalence and tremendous health care cost.[3] Atrialfibrillation (AF) on the other hand is the most common arrhythmia responsible for one third of all the arrhythmia related hospitalization.[4]. This can be attributed to a higher prevalence of traditional risk factors for AF like obesity and hypertension in OSA patients, never the less the relation between AF and sleep apnea is found to be stronger than that of sleep apnea and traditional risk factor of AF.[5]
