Risk of Cardiovascular Events Not Reduced With CPAP Use
Updated: Aug 30th 2016
TUESDAY, Aug. 30, 2016 (HealthDay News) -- While treatment with continuous positive airway pressure (CPAP) reduces sleep apnea symptoms, it does not lower users' long-term odds for cardiovascular events, according to a study published online Aug. 28 in the New England Journal of Medicine. The research was published to coincide with the annual European Society of Cardiology Congress, held from Aug. 27 to 31 in Rome.
Doug McEvoy, M.D., a clinician at the Adelaide Institute for Sleep Health at Flinders University in Australia, and colleagues selected 2,717 patients with moderate-to-severe sleep apnea from 89 clinical centers across seven countries. Most were older males (average age 61), and were overweight, habitual snorers. All had been diagnosed with some form of cardiovascular disease. About half the participants were randomly chosen to receive CPAP, while the others received standard cardiovascular disease care plus advice on trying to maintain healthy sleep without CPAP.
The team found no differences between CPAP users and non-users in rates for heart-related death, myocardial infarction or stroke or transient ischemic attack, or hospitalization for heart failure. For example, 17.0 percent of patients in the CPAP group had a serious cardiovascular event, compared to 15.4 percent of non-users (hazard ratio with CPAP, 1.10; 95 percent confidence interval, 0.91 to 1.32; P = 0.34). CPAP users reported reductions in daytime sleepiness, a boost in health-related quality of life, fewer work days lost, and better mood, with less risk of depression.
McEvoy believes that prior observational studies may have "overestimated" the link between sleep apnea and cardiovascular outcomes. Another factor might be that many participants could only use CPAP about three hours a night. McEvoy pointed out that the study participants who were able to use the treatment even a bit longer -- four or more hours -- did show "a trend toward a reduction in stroke." All of this suggests that "better-tolerated obstructive sleep apnea therapies, or new ways of making CPAP more tolerable, may be needed before a benefit of [the] treatment on cardiovascular outcomes can be shown," he told HealthDay.
The study was funded in part by Philips Respironics; several authors disclosed financial ties to the pharmaceutical and medical device industries.
