National Public Radio

Soon after many people fall asleep, they have trouble breathing. Their upper airway constricts and chokes them. They wake, startled, take a deep breath, and fall back to sleep. Then it happens again and again and again.

This condition, obstructive sleep apnea, affects about a fifth of American adults and triples the risk for cardiovascular disease. How exactly has been unclear.

Research published Wednesday suggests that cholesterol, a common culprit in heart disease, plays a special role in raising risk for people with sleep apnea.
