I'm having chest pain for the past two years and have already done tests like HLA B27 by PCR, ECG, 2D Echo, TMT, and a CT Coronary Angiography. All the results have come back normal, but I'm still dealing with this left-sided chest pain. My recent blood tests show HS CRP is 9.7, Lipoprotein A is 35.09, SGOT is 70.9, SGPT is 88.4, and GGT is 80.9. Now my doctor wants me to do a 2D Echo with a GLS test. What do you think is going on? Is there something specific my doctor might be looking for with this new test?
