Mortality Patterns Associated with Central Sleep Apnea Among Veterans: A Large, Retrospective, Longitudinal Report.

Clinically diagnosed CSA was associated with a shorter time to death from the index diagnostic date. Almost one fifth of CSA patients died within five years of diagnosis. The presence of HF, history of cerebrovascular disease and hemiplegia, male sex, and being underweight were among the highest predictors of mortality in CSA. CSA was associated with higher mortality than OSA, independent of associated comorbidity.
