Thanks for your question on Healthcare Magic. I can understand your concern. In my opinion, you should immediately consult cardiologist. T inversion on ecg is suggestive of ischemia. Your symptoms are also suggestive of ischemic heart disease. Most common cause for this is coronary artery blockage. You are having pre diabetes and strong family history of coronary artery disease. So better to consult cardiologist and get done 1. Blood pressure monitoring 2. 2d echo 3. Stress test (trade mill test) 4. Coronary angiography. You may require coronary stenting and other cardiac supportive drugs. Don t wait at home, consult cardiologist and start treatment immediately. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
