Hello Doctor, My father aged 65years, was Covid19 positive back in September 2019. Two days back, he has undergone master health check up for any side effects of the Covid19 treatment. And his TMT test came out Positive for Exercise Induced Ischemia. He doesn't smoke, he doesn't have any other problems like BP or Sugar.He is physically very active. All other tests like ECG, 2D Echo came out normal and his LDL is at 99. I would like to understand what could be the reason for positive TMT report and what should be the next step for us. Please advise on this issue. Thanks.
