Overview
There is no particular laboratory findings for the diagnosis of aortic dissection. Possible laboratory findings associated with aortic dissection may include troponin elevation, CK-MB elevation, hematuria, and etc. There has been reports of using a smooth muscle myosin heavy chain immunoassay to help diagnose aortic dissection.
Laboratory Findings
There is no particular laboratory findings for the diagnosis of aortic dissection. Possible laboratory findings associated with aortic dissection may include:
- D-dimer elevation
- Troponin elevation
- CK-MB elevation
- Hematuria
D-dimer
- Aortic dissection is more likely in the case of elevated D-dimer levels. It worths mentioning that compared to other causes of D-dimer elevation, aortic dissection leads to immediate rather than gradual increase in D-dimer level. D-dimer elevation has highest diagnostic value in the first hour of symptom presentation.[1]
Cardiac Biomarkers
- Troponin elevation may be observed in approximately 25% of patients with aortic dissection type A. It may be the result of hemodynamic stress and is not associated with poorer prognosis.[2]
- The presence of an elevated CK MB may indicate the presence of concurrent acute myocardial infarction.[3]
Biomarker Studies
- There has been reports of using a smooth muscle myosin heavy chain immunoassay to help diagnose aortic dissection.[4][5]
Urinalysis
- Hematuria may be present and may indicate the presence of renal infarction.[6]

| Class III |
| "In Patients with high clinical probibilty of aortic dissection (risk score 2 or 3), D-dimer evaluation is not recommended. (Level of Evidence:C)" |
| Class IIa |
| "Laboratory tests should always be interpreted along with pretest clinical probability of acute aortic syndrome (AAS). (Level of Evidence:C)" |
"A negative D-dimer test in case of a low clinical probability of acute aortic syndrome (AAS) should be considered as the ruling out diagnostic test.[8][9][10][11]
(Level of Evidence:B)" |
"A positive D-dimer test along with an intermediate clinical probability of acute aortic syndrome (AAS) should warrant further imaging studies.[8][9]
(Level of Evidence:B)" |
