[|Human|] I am a 35 y/o female with a 4 month history of CP with SOA.  I have had a Nuclear Stress test and an Echo, all which were normal.  However, they did find that I have a Left Bundle Branch Block.  I wore a 30 day halter monitor which revealed PVCs/PACs, but not much else.  I had the same chest pain last night above my left breast, with shortness of breath, and left arm numbness.  After an hour I went to the ER.  The normal tests were ordered, but the ER doctor also ordered a D-Dimer, and mine was elevated to 0.65.  All other lab tests were WNL. She ordered a CT Angio of my chest whicChatDoctore back normal.  She didnt explain what could cause the elevated D-Dimer, nor whether or not I should be concerned, or what I should do about it.  I am on Metoprolol and Lisinopril for my heart.
[|AI|]  Brief Answer:The most serious health problems that may increase D-Dimer levels are excluded, and the increase is not significant. Check the D- Dimer level after 1 week. Detailed Answer:Hello, Thank you for using Chat Doctor. I read your question carefully, and I think you don't have to be worried because in your case, the most serious health problems that may increase D-Dimer levels are excluded. As your cardiac enzymes and your ECG did not show any new modifications this means that you were not suffering a myocardium infarction. Anglo CT of the chest is the gold standard for diagnosing pulmonary thromboembolism, which in your case came out to be normal. Also, the rise of the D-Dimer level is not so significant to indicate serious diseases. A venous thromboembolism (VOTE) is also a cause of high D-Dimer levels, but it can be excluded by the lack of symptoms suggestive for it and low increase of D- Dimer level. (Is Usually significant for levels above 1)A more possible cause in your case may be a systemic disease such as dermatological disease or infection. Eventhough, what to do next ?  If I were your doctor, I should advise you to check D-Dimer level in blood after 1 week. Hope this is helpful. Let me know if you need more clarifications. Otherwise, please close and rate the answer. Kind
