If they are not instances of the disease MI, through the class
hierarchy at least, then you have departed from common usage of the
term with respect to real world phenomena. Acute MI would hopefully be
subclassed from MI to provide that link even when a patient has a case
of Acute MI they are also implied to have a case of the disease MI.
