i have frequent chest pains (for the last 6 years) without any occassion and reason. after or before meal, resting or working or sleeping. done at least 60 ECGs, 4 echo, 6 TMT (TMT indicates false positive as the specialist say it reverts to normal very soon on termination of exercise and echo reports are absolutely normal). I exercised for 11 to 14.8 min (on different occassions) and reached THR without any discomfort. All doctors say its atypical chest pain and is noncardiac. i weigh 45 kgs and a nonsmoker, nonalcoholic, and my blood chemistry is all well within limits. iam convinced ofcourse. doctors at CHRISTIAN MEDICAL COLLEGE AT VELLORE INDIA said its due to muscle inflammation, (they conducted an echo and a chest x ray with my previous TMT reports to support).but still the pain scares me. should I go for an angiography. how about a 64 slice CT angiography. does the contrast gel used, has any detrimental effects on the body, especially the kidneys.
