Add yet another factor to the circadian hypothesis of morning heart-attacks

Related to this discussion, there is a new interesting study out - Daily rhythms in blood vessels may explain morning peak in heart attacks:

It's not just the stress of going to work. Daily rhythms in the activity of cells that line blood vessels may help explain why heart attacks and strokes occur most often in early morning hours, researchers from Emory University School of Medicine have found. Endothelial cells serve as the interface between the blood and the arteries, controlling arterial tone and helping to prevent clots that lead to strokes and heart attacks, says Ibhar Al Mheid, MD, a postdoctoral cardiology researcher at Emory.
