Association of serious adverse events with Cheyne–Stokes respiration characteristics in patients with systolic heart failure and central sleep apnoea: A SERVE‐Heart Failure substudy analysis

Background and objective Increases in Cheyne–Stokes respiration (CSR) cycle length (CL), lung‐to‐periphery circulation time (LPCT) and time to peak flow (TTPF) may reflect impaired cardiac function. This retrospective analysis used an automatic algorithm to evaluate baseline CSR‐related features and then determined whether these could be used to identify patients with systolic heart failure (HF) who experienced serious adverse events in the...
