Had a calcium score, coronary cta & stress test bc of caroited artery bruit & chest pains... all norm! is it safe to say the bruit/pain is benign?

Yes.: Sounds as though your carotid has no significant plaque or anatomic cause for your murmur. Therefore benign. Same for your chest pain if est normal.

Results...: If cta, cardiac stress, and calcium score are negative, that is good news for the heart and coronary arteries. As far as the bruit..... Did you have a carotid doppler / ultrasound? Usually this will tell the percent blockage in the carotid which is likely causing the bruit.
