Good news, there is no heart attack. It is normal. If there is recurrent chest pain especially with exertion or chest pain that relieves with rest and recurs on walking, climbing stairs, etc., then to be on safer side, have an ETT (exercise tolerance test) done. In this test, your mom will be asked to walk on a graded ramp and simultaneously ECG will be done. If there are no changes in ECG, non-cardiac chest pain will be confirmed. TSH (thyroid stimulating hormone) and lipid profile are normal as well (attachment removed to protect patient identity).
