Stress and Cardiovascular Disease

Stress activates the sympathetic branch of the autonomic nervous system (ANS).This leads to a constriction of the blood vessels and a rise in blood pressure and heart rate.

An increase in heart rate may wear away the lining of the blood vessels.

Stress leads to increase glucose levels which leads to clump blocking the blood vessels (Atheroschlerosis).
