Cardiolite stress test

45 year old male excellent health planning on training for a marathon so I asked my Family Physician if I could have a Stress Test. He felt it was not necessary because I had no risk factors. He then decided to have me undergo a cadriolite stress test (against his advice).
My history
- 45 year old male
- Physical Education teacher...very active
- Non-smoker
- 1 glass of red wine a day
- one 81 mg aspirin/day. Multiple Vitamin and omega 3's
- jogging 3-5/week 40minutes for the past 20 years. Weight train regularly 2x/wk
- no hx of high blood pressure or high cholesterol or diabetes.  Annual Physical results have all been excellent..
- Height 5'11.5" and weight 173-175 lbs
- stress test and echo in 1989  PAC's noted and Incomplete RBBB, advised that was normal from cardiologist and family physician.
- no chest pain experienced at rest or during exercise.
- resting heart rate around 60b/min.
- no risk factors to mention other than what has been mentioned above.

          Results from MYOCARDIAL PERFUSION STUDY (STRESS)
Stress ECG Report: At REst Pulse was 63 and BP was 118/90. Resting ECG Normal.
The patient exercsied for 13 minutes and 31 seconds on treadmill according to Bruce protocol and achieved 16 METS with peak pulse of 176 which is 101% of maximum and BP of 210/85.
During exercise there were PAC's but no Ischemic ECG changes or chest symptoms.
TOMOGRAPHIC MYOCADIAL PERFUSION REPORT: The stress myocardial perfusion tomograms show mild decrease in the proximal two-thirds of the inferior wall which improves at rest.
The gated images shw normal wall motion.  The rest eject fraction is 44% and the post stress ejection fraction is 48%
OPINION: although the decrease in the proximal inferior wall could be secondary to diphragmatic attenuation artifact.  I think there is some improvement at rest and ischemia in the RCA territory cannot be excluded.
Dr.(Consultant Cardiologist)     and Dr. (Nuclear Phusician)  
I am really worried now.  Maybe I should have not asked for the Stress Test and listened to my Doctor.  He suggested we either redo the test or refer to a Cardiologist at teaching hospital
As soon as I eft the office I went for a a nice 40 minute run no chest pain or shortnes of breath was noted. Should I increase my dosage of baby aspirin? do you think they will recommend another cardiolite test or angiogram?
I think I might have to wait a while for the appoinment.
What's your impression or guess?  I'm worried. What shoud I expect. I enjoy running and exercising.

You might want to talk with your doctor about a 64 slice CT scan.  It will give you a good evaluation of your coronary arteries.  I also believe it will also serve to evaluate the soundness and structure of your heart.  I am not sure of the latter, however.  Your doctor will know.

I saw my cardio today and he had a problem with the descriptive words in the perfusion report.  He said it didn't tell him anything.  He said that we now have to go backwards and r/o the results. My cardio said to keep up with the excercise. He suggested an ECHO and 64 slice Ct scan.  I also had an ECG which indicated sinus bradycardia with a heart rate of 53b/min and RBBB otherwise normal.  He
