Research does not firmly link stress and heart disease, but there’s a growing belief that it’s an additional risk factor, and maybe even more dangerous than some others.
Stress and anxiety can increase my chance of having a heart attack. Stress and anxiety can do this in multiple ways including increasing our blood pressure, increasing our heart rate, increasing the inflammatory markers in our blood stream. Anxiety and stress can make us lose our discipline in terms of exercising and staying in shape. It can also make us overeat which increases our risk for diabetes. These factors will then increase our risk of having a heart attack.
One of the great benefits of exercise is to reduce our anxiety and stress which decreases the hormones in our body that many times lead to increased blood pressure, inflammation, and heart attacks. Adrenaline is one of these mediators and can cause a number of responses in the body when it is elevated chronically due to stress.
To answer your question, yes, in my opinion, stress is bad for those with enlarged aorta.
