On Thursday night I went to the ER with chest pressure, pain in my left arm, and severe jaw pain. I was given an ECG which was normal, and all my labs were normal (D-Dimer at <150 and Troponin-I at <0.03) except for my CK-MB. My CPK total was only 67, but my CK-MB total was 9.1. Where it says CK-MB/CK relative index it states that CKM-MB relative index is not valid when total ck is <100. The normal range (as said by the lab work-up) for CK-MB is 0.3 to 4.0 ng/mL. I was diagnosed with costochondritis (for the 6th time this year...) and sent home.
I didn't even really look at my labs until tonight, but I was taken aback when I saw my CK-MB level.
I still am having arm pain and the jaw pain comes and goes. I'm extremely fatigued (yesterday it was to the point that I couldn't even sit up, so I went and laid down on the couch to watch television. The fatigued lessened, but I was still extremely wobbly on my feet), and have been feeling nauseous for the last 4 days. I don't think I had a heart attack (I'm a 23 year old slender female with perfect blood pressure but high cholesterol with no family history of heart disease), but what else would make CK-MB levels elevate besides heart muscle damage? I have Spinal Muscular Atrophy, but I would think that would only affect CK-MM levels seeing as it's a neurogenic disorder rather than a destructive myopathy like Muscular Dystrophy.
I do have panic disorder, and I realize that this could all be in my head (seeing as I am a hypochondriac), but I don't want to overlook something just because I don't want to seem crazy.
