Thanks for your question on Health Care Magic.
I can understand your concern.
TMT (trade mill test) positive is suggestive of decreased blood supply to heart in exertion.
And most common cause for this is coronary artery obstruction.
At your age of 65 years coronary artery blockade is common due to
atherosclerosis.
So you should definitely get done Coronary angiography to diagnose blockage.
If blockage is there then you will need stenting to open blocked coronary artery. By doing this, we can restore blood supply to heart.
So angiography is not only diagnostic but it is also therapeutic.
You should also start anti platelet and
anticoagulant drugs like clopidogrel and aspirin.
If you don't start treatment, you may end up in
heart failure and
sudden cardiac death.. So better to
consult cardiologist and discuss all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
