| Abstract | ||||
| Background: Sleep-disordered breathing (SDB) is a significant public health concern, including obstructive sleep apnea (OSA) and central sleep apnea. SDB, even in milder forms, stresses the cardiovascular system, leading to complications. While the apnea/hypopnea index (AHI) has traditionally assessed SDB severity, recent research highlights its limitations, emphasizing the need for additional polysomnographic parameters for a comprehensive cardiovascular risk assessment in patients with Sleep Disorders Breathing. Methods: This retrospective study was carried out at the Sleep Disorders Breathing unit, at Zagazig University Hospitals. The study involved 109 participants with cardiac illness and 109 participants without cardiac illness The specialized setting was utilized to investigate polysomnographic parameters and cardiovascular problems in patients with SDB. Results: The primary results of this study revealed that the cardiac group exhibits a lower prevalence of pure OSA (57.9 % vs. 86.1 % in non-cardiac group) but a higher prevalence of mixed sleep apnea (39.5% vs. 13.9% in non-cardiac group) with high statistical significance (P value < 0.001) . Oxygen Desaturation Index, Time of sleep below 90% (T<90%), Arrhythmia Index, and Arousal Index are significantly higher in the cardiac group (P value <.001) but Diastolic dipping of blood pressure is significantly lower in the same group (P value 0 <.001). Conclusions: Polysomnographic parameters other than AHI, such as Oxygen Desaturation Index, Time of sleep less than 90% (T<90%), Arrhythmia Index, Arousal Index, and Diastolic Dipping of blood pressure emerge as a key marker of heightened risk of cardiovascular complications. | ||||
