Overview
Routine blood work is usually not helpful and should not delay definitive diagnostic studies such as a CT scan and treatment.
Complete Blood Count
Hemolysis can be present as a result of blood in the false lumen.
Biomarker Studies
- There has been one report using a smooth muscle myosin heavy chain immunoassay to help diagnose aortic dissection. They report that a level > 10 ng/ml within the first 12h is 90% sensitive and 97% specific. This finding needs to be confirmed in other trials however.
- The presence of an elevated CK MB may indicate the presence of concomitant acute myocardial infarction (often a right coronary artery occlusion due to occlusion of the ostium of the RCA by the dissection).
Urinalysis
- Hematuria may be present and may indicate the presence of renal infarction.
