Earlier today I read an article from Arnold Schwarzenegger talking about his heart issues, specifically about plaque. Of course it’s not from gear but from lifestyle choices. Anyway here is the article from the AHA. There is also a link inside the article where you can read the actual medical study if interested.

Not sticking to a regular sleep schedule may raise the risk for atherosclerosis, a buildup of plaque that can lead to a heart attack or stroke, new research suggests.
