According to a new study, adults with obstructive sleep apnea (OSA), who suffer from excessive sleepiness while being awake, are at greater risk of cardiovascular disease (CVD) than those who suffer from it. not.
Sleep apnea is a potentially serious sleep disorder in which breathing stops and starts again and again.
Adults with moderate-to-severe OSAS were classified into four subtypes based on reported symptoms: disturbed sleep, minimal symptoms, moderate sleepiness, and excessive drowsiness.
"Many studies in our group have shown that patients with moderate to severe OSA worldwide can be categorized into specific subtypes based on reported symptoms," said Diego R. Mazzotti, a researcher at the University of Toronto. 39, University of Pennsylvania in the United States.
"However, until now, it was unclear whether these subtypes had different clinical consequences, especially with respect to future cardiovascular risk," Mazzotti said.
For the present study, researchers followed for nearly 12 years 1,207 adults, aged 40 or older.
Participants reported symptoms such as difficulty falling asleep and staying asleep, snoring, fatigue, drowsiness while driving, and daytime sleepiness.
The findings, published in the American Journal of Respiratory and Critical Care Medicine, showed that participants with the excessively sleepy subtype were three times more likely to have been diagnosed with heart failure than the other three subtypes.
They were about twice as likely to have a heart attack, heart failure, stroke, or cardiovascular death during the follow-up period as the other three subtypes.
In addition, they were also more likely to experience a new or recurrent cardiovascular event during the follow-up period.
According to the researchers, the increased risk of CVD associated with OSA seems to be attributable to patients with excessive sleepiness subtype.
Studies on the cardiovascular benefits of continuous positive airway pressure, or CPAP therapy, for the treatment of OSA should be focused on the subtype of excessive sleepiness, likely to make the most of treatment considered treatment reference by the AOS, suggested the team.
