    Who is at risk for Angina? ?
    ### Response:
    Angina is a symptom of an underlying heart problem. Its usually a symptom of coronary heart disease (CHD), but it also can be a symptom of coronary microvascular disease (MVD). So, if youre at risk for CHD or coronary MVD, youre also at risk for angina.
