is cardiovascular regional?

Answer 1

No it is not regional, the above respondent does not have any practical experience of myocardial infarction, which are as follows:

What are the symptoms of a myocardial infraction, or heart attack?
Symptoms of a heart attack can occur days or even weeks before the actual heart attack. Many patients may not recognize the symptoms, which include uncomfortable pressure, fullness, squeezing or pain in the center of the chest. Other symptoms include pain that spreads to the shoulders, neck or arms, as well as chest discomfort accompanied by lightheadedness, fainting, profuse sweating, vomiting, nausea, a feeling of “impending doom,” anxiety or shortness of breath. Symptoms may disappear and then reappear. According to the American Heart Association, 63 percent of women and 48 percent of men who died suddenly of coronary artery disease had no previous symptoms. About one fifth of all heart attacks are silent, that is, the individual does not even realize that he or she has had a heart attack.

While conventional medical treatments help an individual survive and recover from a heart attack, but they do not get to the root of the problem. By addressing the underlying physiology that caused the heart attack in the first place, as natural medicine treatments do, future heart attacks may be avoided.

Answer 2

???

Cardiovascular refers to blood vessels of the heart.

I suppose one could say yes to your question. A pain in your arm pit, or in a chest muscle can not be your heart.
