Washington: Untreated severe obstructive sleep apnea (OSA) is associated with an increased risk of cardiovascular mortality in the elderly, and adequate treatment with continuous positive airway pressure (CPAP) may significantly reduce this risk, a new study has claimed.“Although the link between OSA and cardiovascular mortality is well established in younger patients, evidence on this relationship in the elderly has been conflicting,” Miguel Angel Martinez-Garcia, lead author of the study from La Fe University and Polytechnic Hospital in Valencia, Spain, said.“In our study of 939 elderly patients, severe OSA not treated with CPAP was associated with an increased risk of cardiovascular mortality especially from stroke and heart failure, and CPAP treatment reduced this excess of cardiovascular mortality to levels similar to those seen in patients without OSA,” Martinez-Garcia said.All subjects in this prospective, observational study were 65 years of age or older. Median follow-up was 69 months.
