Evaluation of TMT abnormalities in asymptomatic persons using myocardial perfusion study.

Exercise ECG (TMT) is one of the very common investigations being used in the periodic medical examination of high risk professionals like airline pilots and executives. We have done a retrospective analysis of 152 asymptomatic persons who reported for myocardial perfusion imaging after being found to have positive TMT in the form of ST-T changes in inferolateral leads. Stress myocardial perfusion scan of all of them were normal. The fact that so many cases of positive TMT based on ST-T changes in inferolateral leads is found to be false positive should make us retrospect on the criteria for deciding positive TMT. The data available with other centers can be examined and a prospective multicentric study can be done to see whether the present criteria for positive TMT need revision.
