What Causes Shortness Of Breath With Negative D-dimer Test?
Question: Im having shortness of breath.i had a d dimer in january came back negative. Im really scared i have a blood clot.i have been through all sorts of doctors since novemeber with nothing going on. My jaw and teeth have pressure. Had mri of head mra and coronary ct angiogram. my cardiologists says that all is fine he said he doesn't think that I have a blood clot in my lung however when I stand up my post kind of goes fast and my blood pressure gets low and I get kind of shaky I don't know what's going on and I just feel like maybe there could be a clot that no one is seeing and he said that it could have been seen on the angiogram in my pulmonary artery
Brief Answer:
No clot is possible
Detailed Answer:
Hello,
first of all - since you're talking about shortness of breath - did you have an oxymetry done? Or arterial blood gases? The results could be very helpful.
A big clot can be safely excluded because of the negative d-dimers test and the clinical picture. A big clot that occludes a large vessel causes a dramatic presentation that may lead to severe blood pressure abnormalities and death.
A small clot that can sometimes escape detection by ordinary radiological tests may occlude small peripheral lung vessels but this condition, usually causes pleurisy, that is pain with the respiratory movements.
Shortness of breath may have various reasons. If your oxymetry or arterial blood gases are normal, then even anxiety may cause it. Since you're very young and you haven't mentioned any relevant medical history, I suppose that anxiety is the most likely diagnosis, although the more serious diagnoses should be first excluded!
I hope I've helped!
You can contact me again, if you'd like using your follow-up questions. Providing the results of oxymetry and arterial blood gases would help a lot.
Kind Regards!
