What does borderline ST segment response mean in TMT?

Question

Hello doctor,

I undergo regular health checkups, and last year, my test reports were normal. I had another health checkup last week. My TMT (treadmill test) showed a borderline ST segment response with fair exercise tolerance. What does this mean? How serious is it? What should be the next step? Tests like the echocardiogram and resting ECG were normal. I am attaching my test reports.

Please advise.

Hello,

Welcome to icliniq.com.

I have reviewed your reports very carefully (attachments removed to protect the patient’s identity). There is no need to worry, as ST-T changes of less than 1 mm are not significant in the inferior leads, and in the anterior leads, the changes are also less than 1 mm. You achieved the target heart rate, and your exercise tolerance was fair. The changes reverted to normal in less than a minute. Given that your echocardiogram was normal, I do not think there is cause for concern. The sensitivity of the TMT (treadmill test) in ruling out coronary artery disease is about 70 percent, meaning that in 30 percent of cases, it can give a false positive. Are you a smoker or do you consume alcohol?

Please reply so I can guide you better.

Thank you.
