Scientifically, doctors are not really sure if stress can cause heart disease. But one thing that is for sure, people who live with a lot of emotional stress usually take up smoking and begin to eat themselves into obesity are far less to exercise.

When someone is stressed, it causes the adrenaline to rush, when this happens it causes the blood to clot faster so therefore it can cause a heart attack or a stroke.]

Duke University did a study that showed doing arithmetic problems can constrict the coronary arteries in such a way that blood flow to the heart muscle is reduced.

There are facts to support that emotional stress can cause coronary disease.

Emotional stress is now associated with behaviors that increase coronary artery disease, and there's at least suggestive evidence that it may even have a direct effect in producing coronary disease.

Not all emotional stress is bad. People in the big corporate word seem to live long healthy lives for the most part. There appears to be evidence suggests that it may be the individual, and not the stress itself that is the problem. People with Type A personalities (time-sensitive, impatient, chronic sense of urgency, tendency toward hostility, competitive) are at higher risk for coronary artery disease than people with Type B personalities (patient, low-key, non-competitive).
