The eye surgery was a success, but now I felt like I had a time bomb ticking in my chest. My PCP referred me to a cardiologist, who told me he was concerned that the test findings were pointing to a possible blockage of the largest artery supplying my heart. What he really wanted was an angiogram, the “gold standard,” but knowing I probably would not consent to such an invasive test, he suggested a myocardial perfusion test to “rule out” a blockage. He gave me the impression that the amount of radiation involved was fairly minimal, more than a chest x-ray examination but not approaching that of a computed tomographic scan. His words to me going out the door were, “Have the perfusion test within the next couple of days.” Now I really felt my health was in danger.
