Post angioplasty symptoms. Should i do?

It has been 10 months of my angioplasty. I am in a very healthy life style. Eating healthy and walks around 6km daily. I generally gets chest pain for few seconds while walk or doing office work in these 10 months. But my doctor said it is not cardiac pain. But 2 days back I got severe pain and pain got relieved after taking sorbitrate. Based on the few questions doctor asked, he said it is very unlikely of a cardiac issue. My smartwatch ecg also detected nothing at that time[watch is good as first time it detected the issue 10 months back] Now he said if I get again this pain get ECG and CT-angio done. Now 2days I did not get that pain but I am feeling fatigued and my chest feels heavy also feeling anxious. What should I do? Should I do everything before I take few days rest. I am already in met xl, axcer 90, nikoran and ecosprin av 75/40.
