Had MCU. TMT report suggests positive ischemic response. Meaning?

I am a fit 47 year male and just had MCU. Very good feedback in all tests verbally. However, TMT report states: Suggestive Positive Ischemic Response. Review by a Cardiologist for management of Suggestive Positive Ischemic Response. May require a MSCT- Scan or cardiac catheterization. Suggestive Positive???

Hi, thanks for using healthcare magic

The treadmill assesses the response of the heart to increased activity. Normally there would an increase in heart rate in response to exercise , in addition to an increase in the output of the heart.

The increase in heart rate results in increased stress or workload of the heart.
If there is any areas of the heart that are affected by a reduced blood supply (ischemia) then they would not be able to tolerated the increased workload.
This would show up as changes on the heart rhythm strip of the treadmill test.

The fact that the results state ' suggestive positive' indicates that there is some evidence of reduced supply in some aspect of the heart which requires further investigation.

If ischemia is confirmed then treatment involves minimising any risk factors such as controlling blood pressure, blood sugar, cholesterol, discontinuing smoking (if this is an issue).

I hope this helps

Hello, and welcome to HCM!

Ischemia means "lack of blood flow". In the case of this particular test, this refers to a lack of blood flow to the heart muscle itself. This can be caused by a variety of things, most commonly coronary artery disease. The coronary arteries supply blood to the heart muscle, and if they become narrowed/constricted (due to smoking, high cholesterol, etc), the heart can become ischemic. The way to tell for sure if this is going on is with a cardiac catheterization. This is an invasive test performed by a cardiologist, where radioactive dye is injected into the coronary arteries, and x-rays are used to directly visualize the arteries. The doctor can then determine for sure if the patient has coronary artery disease. If appropriate, stents can be placed to open up constricted blood vessels.

You would be wise to see a cardiologist soon to discuss the most appropriate course of action.

I wish you the best of health, and thanks for posting on HCM.
