I am 63 years old having hypertension since 1990 but blood pressure maintained with medicine. Recently I underwent tmt & eco tests and was declared as TMT positive. now I have the following queries.-whether tmt positive relates with coronary artery blockage? if so, then what is the percentage of blockage?-how is often is TMT positive related with heart attack?-Is angiography recommended for further investigations?
Hello 1. A positive TMT has a 78% sensitivity for coronary artery disease which increase further more with age more than 60 along with Hypertension and diabetes. Blockage percentage cannot be given by TMT. Angiogram is done for that.2. A positive TMT means that an individual might be having a coronary heart disease it's not related to heart attack. However, a patient can have a heart attack while doing TMT 3. Yes Angiography is the Gold standard test for further evaluation. I wish you good health
