Still, this isn’t the first study to make the connection between sleep issues and heart disease. Full, Ph.D., M.P.H., assistant professor of medicine at Vanderbilt University Medical Center. “It is likely that the link is multifactorial and sleep may play an important role of many factors,” says lead study author Kelsie M. ![]() “Irregular sleep may also indicate irregular lifestyle habits such as irregular timing of food, poor food habits, and diet that were not taken into consideration,” points out Jag Sunderram, M.D., interim chief in the Division of Pulmonary and Critical Care Medicine at the Rutgers Robert Wood Johnson Medical School. At the same time, this particular study found a link between irregular sleep and atherosclerosis, but didn’t show that having irregular sleep patterns actually causes atherosclerosis. It’s important to note that heart disease-including atherosclerosis-is a complicated condition that can have many causes. Why might irregular sleep patterns raise your risk of heart disease? The researchers concluded that regular sleep patterns could be a “modifiable” factor in helping people to reduce their risk of atherosclerosis. they mixed up when they went to bed and when they woke up) were 1.43 times more likely to have high coronary artery plaque compared to those who had sleep timing that varied by 30 minutes or less within a week. Those who had more irregular sleep timing (i.e. People with irregular sleep durations that varied by more than two hours a week were 1.12 times more likely to have carotid plaque (plaque in arteries that deliver blood to your brain). Specifically, those whose sleep durations varied by more than two hours in a week were 1.4 times more likely to have high coronary artery calcium scores (which measures the amount of calcified plaque in the arteries, the main underlying cause of cardiovascular events such as heart attacks and strokes) compared to those who had more consistent sleep durations. The researchers conducted a slew of tests to look for buildup of plaque in the arteries (a condition known as atherosclerosis, which can cause a heart attack, stroke, or blood clot) and found that people with irregular sleep patterns were more likely to have higher levels of plaque compared to those with more consistent sleep schedules. Overall, the biggest irregularity in the number of hours study participants slept was more than two hours in one week, and those with the biggest irregularities varied the time they fell asleep by more than 90 minutes in one week. Participants also did a one-night, in-home sleep study to look at their breathing, sleep stages, waking after they went to sleep, and heart rate. From 2010 to 2013, the study participants wore a device around their wrist that tracked when they were asleep and awake, and they also filled out a sleep diary for seven straight days. The study, which was published in the Journal of the American Heart Association, analyzed data from more than 2,000 adults from across the country with the average age of 69.
