Coexistence Of Central Sleep Apnea And Periodic Breathing Pattern In Patients With Congestive Heart Failure And Obstructive Sleep Apnea

Abstract Introduction: Sleep breathing disorders occur in 45% of patients with heart failure, with 36%-50% manifesting Cheyne-Stokes respiration with central sleep apnea and 12% exhibiting obstructive sleep apnea. Several studies have shown that sleep pathophysiology may negatively affect the cardiovascular system and that cardiac dysfunction alters sleep and respiration. Objective: The aim of this study was to examine oxyhemoglobin desaturation during sleep in patients with congestive heart failure (CHF) using overnight pulse oximetry. Methods: Overnight pulse oximetry was conducted in the patients' homes with wrist pulse oximeters and finger probes that were placed around the forefingers of 15 patients with CHF and ejection fractions less than 50%, who were classified as New York Heart Association functional classes II and III. Results: The patients were divided into two groups. The first group consisted of seven patients with oxyhemoglobin desaturation indices of over 5 events/h, and the second group contained eight patients with oxyhemoglobin desaturation indices of 5 or less events/h. Student's t-tests did not show any significant differences between the groups. The patients' body mass indices correlated positively with the total desaturation episodes and desaturation time less than 90% and correlated negatively with the arterial oxygen saturation nadir. Conclusion: Pulse oximetry monitoring during sleep can be used to detect sleep breathing disorders in stable patients with CHF.

High Prevalence

The problem of heart failure (HF) is one of the central problems in modern cardiology due to its high prevalence among the population and high mortality. In turn, sleep-related breathing disorders (SRBD) are widespread in patients with HF and are associated with both the progression of the underlying disease and a decrease in the quality of life. For the first time, periodic breathing, as one of the types of sleep breathing disorders, was described in patients with HF.Further study of the issue showed a high prevalence of other types of SRBD among patients with HF The article discusses the physiology of sleep breathing monitoring in a healthy person and the pathophysiology of SRBD. The pathogenesis of central sleep apnea and its relationship with HF are discussed in detail. In addition, the mechanisms of the adverse effect of obstructive sleep apnea and HF are highlighted.
