U.S. News & World Report discusses the relationship between sleep apnea and heart failure.

Sleep apnea, pauses in breathing during sleep, doesn’t just leave you tired – it can lead to heart failure if untreated, Curry says. At St. John’s Prairie Heart Institute, “even though patients say they don’t snore or have problems [where] they’re not sleeping at night, we’ll do a sleep study to confirm that,” she says. Patients found to have apnea are put on a CPAP device to make sure they get enough oxygen during sleep.
