Overview
Serial troponins and CK-MB should be ordered. Additional laboratory tests include serum electrolytes, a complete blood count, renal function tests, and liver function tests.
Laboratory Findings
On the basis of the above, a number of tests may be ordered:
Cardiac Markers
- Troponin I or T are now cardiac marker of choice and are preferred over creatine kinase.
- No one marker gives accurate diagnosis so commonly two markers are used for instance Troponin I or T with creatine kinase (and CK-MB fraction in many hospitals)
Blood Tests
- D-dimer (when suspicion for pulmonary embolism, aortic dissection)
- Complete blood count
- Electrolytes
- Renal function (creatinine)
- Liver function tests
