Last few months I have been short of breath, tight feeling in my chest and pain. Saw Dr normal chest radiographs and blood work up and ECG.A few months later I was in th hospital. I am a 27yr old female. Severe squeezing pain in my chest, than both arms went numb, total body sweating and starting vomiting while laying on the ground waiting for the ambulance to arrive. One the they arrived my blood pressure had tanked and heart rate was in the low 40's. ECG was abnormal during attack in the ambulance but once chest pain was gone ECG was normal. Elevated heart enzymes as well. Heart echo was normal no damage or abnormalities, but inflammation and edema in my lung that wasn't there on previous radiographs 2 months prior. Dr's are unsure of cause all blood work WNL other than elevated cardiac enzymes that have returned to normal. Are there other conditions that would cause a 27 yr old female to have a heart attack. Not over weight, no diabetis or high cholestrol?
