The question centered on the term CONSIDERED and then IF not Why not. Thru my personal experiences in conversations with cardiology patients I have come to the realization that considerations often are determined more by by the ability of the practices involved than the procedures currently available. Referral are not always resorted to or suggested, unfortunately. Furthermore it has become necessary for the patient to be very pro active. Read and gain as much knowledge as one can regarding the medical issue being addressed. Ask questions. Be informed as much as possible. Yes, RESPONSIBILITY pertains to the patient as well! It is of help to the Cardiologist as well as the patient.
