The study lead by researchers at Massachusetts General Hospital and Harvard Medical School measured the effect of stress on 300 people over nearly four years.

Scientists use scans to monitor a tiny area of the brain called the amygdala which processes emotions such as fear and anger, they found for the first time in studying humans that higher levels of activities in the amygdala were linked with greater activities in bone marrow and inflammations in the arteries.

They suggested the amygdala tells bone marrow to produce extra white blood cells, which cause arteries to develop blockages and to become inflamed.
