Angina or Radiculopathy

I have been searching the internet to find out if the following is possible.

When a person damages their upper spine (C3 through T4) resulting in multiple herniated disc, the worse being at T2-T3 with a moderate sized posterior disc protrusion with mild mass effect on the cord (using a T2 MRI Scan on a large chested man), plus having an EMG in the upper right (only side checked) thoracic paraspinal muscles, and definite positive sharp wave activity was seen in the upper (he wrote lumber, but I thought he was checking thoracic) levels at approximately T2 or T3.  Numbness and weakness in both legs and arms – which varies depending on activity and arm positioning.

Can this type of injury cause the Coronary Arteries to somehow constrict and cause ANGINA, without showing any signs of coronary artery disease in EKG’s, Treadmill Stress Test, Echocardiograms, Blood Test?  Yet, never having any pain during any of these test, and the only time the pain does come, is after the drive to work, when I walk from the car to the building I work in almost every morning.  

Also, when I lay down on my back, to go to sleep, my heart starts to pound, miss beats, and race.  I have to turn on my side in order to get it to stop acting up.  I also at times cough to stop it from beating so weird.  This also happens if I sit leaning back and raise my arm up on the arm chair, I then have to sit up straight.  

This all started when I injured my spine.  Two years prior to this injury, I had an angiogram due to a false positive on some sort of radioisotope X-Ray.  The result of the angiogram was “Your arteries are so large, you should never need to have another one of these as long as you live”.  I do have hypertension, which now goes all over the place. As High as 200/120 sitting, to as low as 109/59  - Sitting   Heart rate as high as 100 sitting (on 100 mg of Tenormin) to as low 68 sitting.

I can’t seem to find this happening to anyone else and I have to say that the pain is excruciating, to where it makes breathing very difficult and at times brings me to tears.

If you ask me if I think the pain is my heart – at first I did not think so, but now, it seems to only come on when I walk, and stops after I relax a while – I tried nitro, and it relieves it.

I just need to know if this type of injury can cause the coronary arteries to constrict.

If so, how?  Or, can you please lead me to some literature that I can read to find out how.

Thank you for your time,
