Hello Shwetha and welcome to HCM
I am a jr. to cardiologist and read your mail in detail. Firstly I want to know the severity of chest pain
, when it started, does you get relief from chest pain by taking Tab. Sorbitrate
spray, is pain associated with breathlessness, does your father feel chest pain and breathlessness on exertion?
Alone TMT positive for inducible ischemia does not means that their is a block in coronary artery. Although TMT positive is a strong indication for Coronary heart disease
but you must have changes in ECG and associated symptoms present and most importantly you must achieve 80% heart rate
at the time of TMT. Other important sign is what is the cause of stopping the TMT whether it is chest pain or Leg and back pain.
As you have explained that your father has leg and back pain so their is possibility of false report of TMT. But as the patient is Hypertensive and Diabetic, there is also possibility of block of graft done during CABG. Usually the possibility of graft block is after 8 -10 years but lot depends of regular intake of medication and life style.
My last opinion is to consult your cardiologist immediately and get your father checked clinically and go for investigation as per his advice and even go for Coronary Angiography
if he advise. Till you get the consultation keep the Tab. Sorbitrate in your pocket all the time and take regular medication for Hypertension
and Diabetes Mellutus.
