Uncovering the link between emotional stress and heart disease
The brainís fear center may trigger inflammation and lead to a heart attack. But stress reduction techniques can break the chain. A small, almond-shaped area deep inside the brain called the amygdala is involved in processing intense emotions, such as anxiety, fear, and stress. Now, a new brain-imaging study reveals how heightened activity in the amygdala may trigger a series of events throughout the body that raises heart attack risk.
