Hi,
Thanks for writing to Health Care Magic, I am Dr Asad Riaz, I have closely read your question and I understand your concerns, I will hereby guide you regarding your health related problem.
ETT is done to rule out underlying
ischemia but it is only 77% specific n can give wrong result or either not show any thng even patient may have Hiden IHD that may come as in form of
heart attack later at any stage ... this report showed that ur father had not good exercise capacity mean heart is not functioning good n as he might have other risk factor for coronary
artery disease n along with this report he need to undergo to
angiography to make sure is isn't having serious underlying pathology .. But if ur father iOS hesitating to under go intervention tha. CT angio can be down to look for any CAD( stenosis ) with doing intervention ... I suggest ur father should go for further investigation as advice by ur cardiologist , but u can choose the procedure that whether to do CT /coronary angiogram n then will Tx accordngly after report ...
I hope this answered your question, if you have more feel free to ask.
Regards.
