<s>[INST] Hi,I am 34 years old, no diabetic, no BP, no cholestrol.  Last week; i faced a pain in my left arm.  So, i under gone for ECG & 2D Echo .  Doctor told that no problem in 2D Echo and slight variation in ECG.  Then they perform TMT, it is also slight variation and doctor told in this age, TMT should not be like this...please let me know...is there any problem to me [/INST] Hi There After going through your query I understand your concern. I would like to tell you that an abnormal TMT can be the outcome coronary artery disease. Generally chances of symptomatic coronary artery disease in adults are less until unless either they have strong family history of CAD or are heavy smokers. You might need a further evaluation test like Coronary Angiography for proper treatment. Hope to have been Helpful. Kind Regards </s>
