| Background: Chronic heart failure (CHF) is a common disease worldwide with a high morbidity and mortality rate. Sleep disordered breathing (SDB) is a common condition that frequently occurs alongside heart failure (HF) and has a significant effect on the patient's prognosis. Aim of the work: Determining the prevalence, severity, and patterns of SDB in different types of CHF and defining the diagnostic utility of SDB scores in the prediction of SDB in HF patients. Patient and Methods: Sixty (CHF) patients were divided into 3 equal groups based on (LVEF%) into HFrEF, HFmrEF, and HFpEF according to ESC guidelines. All patients underwent full night attended polysomnography. Results: The three groups had a prevalence of OSA of 50%, 55%, and 60%, respectively, and a prevalence of CSA of 35%, 30%, and 5%, respectively. Patients with CSA showed a highly statistically significant (p<0.001) reduction in mean LVEF%. Patients with OSA had significantly higher BMI, NC, and Mallampati scores (p<0.001), all of which were statistically significant increases. While the ESS and Berlin questionnaires showed great specificity (92.3%) and low sensitivity (38.3% and 46.8%, respectively) in predicting SDB in HF patients, the STOP-BANG score showed high sensitivity (100%) but low specificity (30.7%). Conclusion: In CHF patients, SDB was shown to be quite prevalent (78.3%). Higher BMI, NC, and Mallampati scores were associated with higher odds of OSA, whereas lower LVEF% was associated with higher odds of CSA. A good screening tool for SDB in HF patients appears to be the Berlin questionnaire in conjunction with the STOP-BANG score. | ||||
