Abstract

The present invention relates to methods and compositions for symptom-based differential diagnosis, prognosis, and determination of treatment regimens in subjects. In particular, the invention relates to the use of biomarkers, either individually or in combinations with one another to rule in or out diseases of the aorta and its branches, most particularly aortic aneurysm and/or aortic dissection, and for risk stratification in such conditions. Preferred markers include one or more of creatine kinase-BB (CK-BB), creatine kinase-MB (CK-MB), acidic calponin, basic calponin, B-type natriuretic peptide (BNP), NT-proBNP, proBNP, BNP.sub.79-108, BNP.sub.3-108, caldesmon, caspase-3, D-dimer, soluble elastin fragments, endothelial cell-selective adhesion molecule (ESAM), fibrillin-1, heart-type fatty acid binding protein, MMP-9, myeloperoxidase, myoglobin, smooth muscle myosin, smooth muscle myosin heavy chain, TIMP-1, free cardiac troponin I, complexed cardiac troponin I, free and complexed cardiac troponin I, free cardiac troponin T, complexed cardiac troponin T, and free and complexed cardiac troponin T, and preferred assays are configured to detect these markers.
