My mom was having chest pain on 29.11.2012 left side. . we immediately had ecg then we have taken advice from 2 doctors one doctor told do ct angio a?

Cta is an option: Is an anatomic evaluation and not a functional one. It involves alot radiation and dye. If its markredly abnormal or perfectly clear its a great test. But often its not clear as an intermediate blockage may or may not cause chest pain. The next test they reccomend is then a stress test. Then if symptoms persist a catheterization is rec. Thats alot of dye a radiation. I would just go right to cath.

Correct: Ct angio can guide you if there is coronary plaques or need furthe\ evaluations.
