A Cleveland Clinic examine reveals that bariatric surgical procedure carried out in sufferers with weight problems and reasonable to extreme obstructive sleep apnea is related to a considerably decrease danger of demise and main adversarial cardiovascular occasions, in contrast with sufferers who didn’t have the surgical procedure. This examine was revealed within the Journal of the American Faculty of Cardiology.
Ali Aminian, M.D., director of Cleveland Clinic’s Bariatric & Metabolic Institute and first investigator of the MOSAIC examine, mentioned, “The analysis reveals that weight reduction achieved with bariatric surgical procedure is considerably related to a 42% decrease danger of main adversarial cardiovascular occasions and 37% decrease danger of demise in sufferers with weight problems and reasonable to extreme obstructive sleep apnea.”
In line with a examine revealed in The Lancet Respiratory Medication, practically 1 billion adults around the globe have obstructive sleep apnea. One of the widespread danger elements for growing the sleep problem is weight problems. The Weight problems Medication Affiliation experiences that about 70% of grownup sufferers with obstructive sleep apnea have weight problems.
Sufferers with obstructive sleep apnea – which may disrupt metabolism and trigger extra weight achieve – are at an elevated danger of growing life-threatening situations, together with coronary heart assault and coronary heart failure. The Cleveland Clinic-led MOSAIC (Metabolic surgical procedure for OSA and Incident Heart problems) analysis is the primary of its variety to report information on the long-term cardiovascular outcomes of bariatric surgical procedure in sufferers with obstructive sleep apnea and weight problems.
The observational examine included 13,657 grownup sufferers with a physique mass index between 35-70 and the presence of reasonable to extreme obstructive sleep apnea (recognized by a sleep examine take a look at) between 2004 and 2018. Baseline medical traits of 970 sufferers who underwent bariatric surgical procedure have been balanced with 12,687 sufferers within the nonsurgical management group utilizing overlap weighting strategies. Observe-up led to September 2022.
On the finish of the examine interval, outcomes present that the cumulative incidence of main adversarial cardiovascular occasions at 10 years was 27% within the bariatric surgical procedure group and 35.6% within the nonsurgical group. A serious adversarial cardiovascular occasion is outlined as the primary prevalence of coronary artery occasions, cerebrovascular occasions, coronary heart failure, atrial fibrillation, and all-cause mortality. Further evaluation reveals that the cumulative incidence of all-cause mortality at 10 years was 9.1% within the bariatric surgical procedure group and 12.5% within the nonsurgical group.
There are presently no accepted drug therapies for obstructive sleep apnea. Earlier than the MOSAIC examine, no remedy had been proven to scale back the chance of main adversarial cardiovascular occasions and demise in sufferers with sleep apnea.”

At 10 years, sufferers within the bariatric surgical procedure group misplaced 33.2 kg and sufferers within the nonsurgical management group misplaced 6.64 kg. Sufferers within the bariatric surgical procedure group maintained 25% weight reduction not less than as much as 10 years following the process.
“The present administration pointers of obstructive sleep apnea advocate weight reduction and life-style modifications,” mentioned Nancy Foldvary-Schaefer, D.O., director of Cleveland Clinic’s Sleep Issues Middle. “The MOSAIC examine findings help these suggestions. Nevertheless, relatively than specializing in life-style modification alone, treating weight problems with more practical and sturdy strategies akin to bariatric surgical procedure could be required to enhance cardiovascular outcomes and survival in sufferers with obstructive sleep apnea and weight problems.”
Dr. Aminian added, “In choose sufferers, bariatric surgical procedure is a lifesaving therapy. The MOSAIC examine suggests the presence of a dose-dependent response between the quantity of weight reduction and cardiovascular advantages in sufferers with obstructive sleep apnea; the higher the burden loss, the decrease the chance of coronary heart issues. With emergence of a brand new technology of weight problems drugs that may present a median weight reduction within the vary of 15-20%, related findings are theoretically potential from medical therapies.”
