Subjects will have a blood draw for the following biological factors that are important to cardiac health and may be modified by psychological states: Inflammation will be measured via interleukin-6 (IL-6) and high sensitivity C-reactive protein (hsCRP), soluble intercellular adhesion molecule-1 (sICAM-1), tumor necrosis factor alpha (TNF-α), and overall cardiac prognosis will be assessed using N-terminal pro-brain natriuretic peptide (NT-proBNP). A total of 15 ml/cc of blood will be drawn (this is equivalent to 3 tablespoons of blood).
