摘要
Background Obstructive sleep apnea (OSA) may have an association with bradyarrhythmias but often remains undiagnosed. Our aim was to determine if patients with a high risk of OSA attending our cardiology clinics had an association with symptomatic bradyarrhythmias, as this information might lead to changes in management strategy. Methods The Berlin questionnaire was used to assess risk of OSA in 190 patients, and they were divided into high-risk or low-risk groups. Demographic data and medical histories were recorded and patients groups were compared with t-tests and chi-square tests. A multivariate regression analysis was done to correct for confounding variables. Results The mean age of our sample population was 63.0 +/- 14.7 years with a mean BMI of 29.5 +/- 7.8 kg/m(2). Using the Berlin questionnaire, 41.3% of the patients were classified as high risk; 15.7% of the patients had a known diagnosis of OSA. Between high-risk and low-risk groups, there was no significant difference in the prevalence of bradyarrhythmias (22.5 vs. 15.2% P = 0.21), symptomatic sinus node dys14.4 vs. 11.4% P = 0.66) or atrioventricular block (10.8 vs. 6.3% P = 0.33). A multivariable logistic regression analysis demonstrated that dyslipidemia had the strongest association with a high risk for OSA, but not bradyarrhythmias. Conclusions Based on the Berlin questionnaire, patients at a high risk for OSA did not have an increased prevalence of bradyarrhythmias. More studies are needed to assess the utility of evaluating patients with bradyarrhythmias for OSA prior to implanting permanent pacing devices.
