A Family Practice News report indicates that patients with untreated obstructive sleep apnea who underwent PCI were more than twice as likely to undergo repeat revascularization during the next 4.8 years.

The first-in-kind finding “provides new evidence that untreated moderate-severe OSA [obstructive sleep apnea] is an independent risk factor for repeat revascularization after PCI [percutaneous coronary intervention] and that CPAP can reduce this risk.,” said Dr. Xiaofan Wu at the Beijing Anzhen Hospital at Capital Medical University in Beijing and her associates. “Interestingly, the data show that untreated mild OSA was not associated with an increased risk of repeat revascularization, suggesting a dose-effect relationship between OSA severity and risk of complications after PCI.”
