pulmonary clots

i had read something on the pulmonary forum  when i was looking for info on SOB,   there was discussion about repeated pulmonary emboli  leading to SOB symptoms,  I am wondering about this myself,   I had normal clotting factor tests,   is that the test which checks for that sort of thing?    

How else do you find out what shortness of breath is when you have a normal echo, lung function tests,  stress test,  CTA,   chest Xray,  CBC, chemistry, Liver, Thyroid,  ESR of 0,   clotting factors normal?   Well actually my cardiolite test indicated mild hypokinesis in the anterior wall, but CTA was normal.     Could that still be whats caausing my SOB, palps, near syncope and fatigue??
What else do you look for after all that tests?

If you have had pulmonary emboli it is likely this would have been seen by the CTA which would visualize your pulmonary arteries.
