I get angina symptoms but the doctors say that my heart is fine. small vessel disease showed up in stress test, cta, x-ray, echo and ekg. i have 10 lesions in my brain and theyre trying to rule out ms but would they miss svd in mri?

Depends: The brain i assume was evaluated with the cta and MRI with contrast. The heart with a stress test . Not sure from your question if a cta was done of the heart. If your having on going chest pain but tests look ok , then arterial spasm , small vessel dz, non cardiac sources should be ruled out. Can't really tell what tests were done for your heart vs brain. ? What type of stress was done etc.

See below: Consider being checked for antiphospholipid antibody syndrome which is a clotting disorder which could explain some of your symptoms. If you have had blood clots or miscarriages in the past, you definitely need to be checked.

No: Small vessel disease typically not seen with any of the above tests. Sometimes we can see in angiogram. Sometimes it is more of a clinical diagnosis.

No, if done correct: Both stress test with radiotracer (nuclear stress test) and cardiac MRI with contrast can have findings that correlate with small vessel disease. If a nuclear stress test is definitely positive, the CTA negative and the person has typical anginal symptoms; they more likely have small vessel disease than anything else. Chest pain on a treadmill remains the most reliable indicator for true angina.
