While driving home after work, a 45-year-old male construction worker is involved in a collision with another car. Upon arrival in the emergency department, the patient complains of chest pain along with severe pain from accident injuries. X-rays and laboratory assays including cardiac biomarkers are ordered.
Biomarker | Reference Value | Patient Result at Presentation | Patient Result at 6 Hours | Patient Result at 12 Hours |
CK-MB | < 5.0 ng/mL | 7.0 ng/mL | 6.0 ng/mL | 6.5 ng/mL |
cTnI | <0.04 ng/mL | 0.03 ng/mL | < 0.04 ng/mL | < 0.03 ng/mL |
Do the cardiac marker results indicate that an AMI is causing his chest pain?
