I've just been reading up on heart disease can also be triggered from *silent inflammation* - a book that talks about this is called "The Anti-Inflammation Zone: Reversing the Silent Epidemic That's Destroying our Health" by Dr Barry Sears.
Excerpt: ...vasospasm, the second cause of fatal heart attacks. Pro-inflammantory eicosanoids act as powerful constrictors of your arteries and can lead to a vasospasm, a potentially fatal cramp or "charley horse" that prevents blood flow to the heart. Lack of levels of long-chain omega-3 fatty acids in the heart can also lead to a fatal heart attack cause by chaotic electric rhythms in the heart. This condition, called sudden death, accounts for more than 50% of all fatal heart attacks.
