Could I have had a mild heart attack??????

[Sam220]

Two years ago, as a healthy but extremely stressed 57-year-old female, I experienced severe back pain while camping.  It began as just an annoyance in the morning, between the shoulder blades, and grew in intensity until I was on the ground crying.  I did have shortness of breath, although I just thought that was because of the pain.  My kids told me I looked green, though I don't remember experiencing any nausea.  I also experienced debilitating exhaustion after, as though I'd been drugged.  It didn't occur to me at the time, believe it or not, that it was anything more than a torn muscle or something, although the pain was entirely gone the next day.  When I returned I got checked & was told I have a new RBBB, and a stress test indicated a small fixed perfusion abnormality in the proximal to mid inferoseptal region.  My doctor told me at the time that it was just an anomaly in the testing, that I just had a "pulled  muscle," and said there was no indication of any arterial blockage in the results.  Is this something I should see a cardiologist about?  I'm questioning because I don't have insurance, and have been laid off.  I do have a history of palpitations and arrythmias, with palpitations occurring at night, and a strong family history of heart disease.  I am extremely health conscious.
