If, and i stress if, a person was experiencing anxiousness caused by impending heart attack or circulatory issues; would exercise make it better/ wors?

Worse: If one is actually having circulation problems to any muscle, including the heart, then exercising those muscles will require more oxygen due to more work. This will, in turn lead to less oxygen to the organ than it would when at rest. So, if you are concerned you may having heart pain or circulatory insufficiency, see doc immediately. ...Read more
