A new study finds the less sleep you get, the more likely you are to suffer from heart disease.

Patients who either slept less or had elevated blood pressure after falling asleep had a modest 20 to 30 percent increased heart disease risk. - Get more L.A. breaking news, weather, traffic and sports - Have a news tip? Send your tips, video, or pictures
