Hello, I'm a 35 year old female with chest pressure that goes into my jaw and left arm for the past 6 weeks. I had an episode of chest pressure that lasted for about 36 hours. Went to the ER where they did the typical EKG, bloodwork, chest x ray and CT scan with contrast of my chest. Everything came back good and I was released to follow up with my PCP. My cardiac enzymes were perfect but my D Dimer was 5.2 which they said was very slightly elevated so that's why they the CT scan. I have had an echocardiogram and a stress echocardiogram done in the past 2 weeks. Both were perfect. I weigh 139 lbs, 5'3 and I'm a light smoker. No family history, no HBP, cholesterol good and no diabetes. ER doc told me to start looking elsewhere for answers to my chest pressure. Can I be confident that this is not heart related? He said the risks of a cardiac cath are too great and I don't need one.
