Hi Guy's and thanks for the replies. To put you in the picture it's not me who has this problem. I am the defender in a court case were my wife and I are looking to take residency of our niece who is 4 and was orphaned in February of this year. We are going to court against her grandparents who are in their 60's and we are in late 30's. Anyway we know her grandfather has angina and was admitted to hospital twice with suspected hart attacks, all of the research I have done suggests unstable angina but he claims to have stress angina, I was just wandering if there was such a medical condition.
going along with Jerry's assumption that you mean emotional stress, it could work like this: if the stress releases adrenalin and that makes your heart pump harder, then your heart requires more oxygen. If your coronary arteries have any blockage, they may have been allowing enough blood flow under normal conditions but can't allow enough blood for the increased demand, At the same time, arteries throughout your system contract, so that also makes the heart pump harder.
This would be a case of 'stable angina'. You'd expect to get the same results from exercise, etc.
But if it only happens from emotional stress, that sounds more like 'variant angina', in which some trigger (like emotion) causes the coronary arteries to constrict - thereby allowing less oxygen and resulting in the pain, etc
This NIH page lists emotional stress as a possible trigger:

I can't answer your question but assuming your question is can emotional stress cause angina, I'd guess no. However, emotional stress can cause heart problems.
If I understand your question a better search could be can emotional stress cause high cholesterol or otherwise cause artery blockage.
I may have misunderstood your question. If you got that diagnosis from a medical doctor I think it reasonable to ask what/how.
