A new medical study explains why there is a direct correlation between stress and heart attacks. Scientists discovered that increased brain activity in the area of emotional processing (the amygdala) directly increases the risk of cardiovascular events.

Overwhelming emotions and traumatic memories linked with current traumatic experiences increase the metabolic activity in the amygdala. Researchers proved that the brain activity of the amygdala causes increased hematopoietic tissue activity (in the bone marrow, where blood is made) and increased vascular inflammation, both of which directly increase the occurrence cardiovascular disease, stroke, heart attack and angina. The link is so pronounced that researchers are advocating stress levels to be considered an independent risk factor for heart disease, along with other risk factors like smoking and obesity.
