People who suffer from insomnia were 69% more likely to have a heart attack compared to those who didn't have the sleep disorder during an average nine years of follow-up, according to new research. In addition, when looking at sleep duration as an objective measure of insomnia, researchers found that people who clocked five or fewer hours of sleep a night had the greatest risk of experiencing a heart attack. People with both diabetes and insomnia had a twofold likelihood of having a heart attack.
