Heart of the matter, iron, vitamin D, plaque

New research on heart disease and its prevention, from Science Daily:

Plaque-causing bacteria can jailbreak from the mouth into the bloodstream and increase your risk of heart attack, says a scientist at the Society for General Microbiology.

Survival rates in heart failure patients with reduced levels of vitamin D are lower than in patients with normal levels, according to a major study at University Medical Center, Groningen, Netherlands.

Recent research has now demonstrated that iron deficiency affects at least one-third of non-anaemic chronic heart failure patients, according to a presentation at the European Society of Cardiology's Congress 2010 in Stockholm.

Researchers have provided the first direct evidence using a biological marker --  a method to measure cortisol levels in hair -- to show chronic stress plays an important role in heart attacks.
