Due to its insidious and chronic nature, CSA often remains unrecognised. Patients with CSA typically present with symptoms, such as daytime fatigue, recurrent heart failure decompensations and cardiac arrhythmias. Although the pathophysiology of CSA is not yet fully understood, the most widely accepted theory suggests that fluctuations in PaCO2 levels, particularly crossing the apnoeic threshold, play a central role in its development. CSA is associated with various changes, including activation of the sympathetic nervous system, neurohormonal disturbances and haemodynamic perturbations, all of which contribute to increased morbidity and mortality. Transvenous phrenic nerve stimulation (TPNS) has been demonstrated to be a safe and effective therapy for reducing the apnoea\u2013hypopnoea index and improving both left ventricular ejection fraction and quality of life in patients with CSA. These benefits have been validated in randomised clinical trials (RCTs). New methods of analysing RCTs were recently introduced. Applying the win ratio method in a post hoc analysis of the primary RCTs evaluating TPNS suggested that TPNS may also contribute to reduced mortality and fewer heart failure hospitalisations. In this article we explore the pathophysiology of CSA and evaluate the existing evidence on therapeutic options, with a particular focus on TPNS.<\/jats:p>","DOI":"10.15420\/cfr.2025.07","type":"journal-article","created":{"date-parts":[[2025,8,22]],"date-time":"2025-08-22T09:32:52Z","timestamp":1755855172000},"source":"Crossref","is-referenced-by-count":1,"title":["Revisiting Transvenous Phrenic Nerve Stimulation in Central Sleep Apnoea and Heart Failure: Emerging Innovations in Clinical Trials Analysis"],"prefix":"10.15420","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9714-1752","authenticated-orcid":false,"given":"Tarek","family":"Bekfani","sequence":"first","affiliation":[{"name":"Department of Cardiology and Angiology, University Hospital Magdeburg, Magdeburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph D","family":"Abraham","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, The Jewish Hospital, Cincinnati, OH, US"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William T","family":"Abraham","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Medicine, The Ohio State University, Columbus, OH, US"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6096","published-online":{"date-parts":[[2025,8,20]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Oldenburg O, Lamp B, Faber L, et al.
