There are two major links between the stress response and the development of coronary heart disease, which the American Heart Association now estimates kills one person every thirty-two seconds. ... These agents increase heart rate and myocardial contractility in order to cause the heart to pump a greater supply of oxygenated blood to the body’s muscles for energy production. ... This damage to the vessel walls appears as small microtears, particularly in the intima lining of the coronary heart vessels, which supply the heart muscle (myocardium) itself with oxygen. ...
The second link between coronary heart disease and the stress response is the release of coristol from the adrenal medulla. ... However, what may seem like a protective mechanism actually becomes a major hindrance to the efficiency of the heart muscle, causing coronary heart disease.
