- Primary Outcome Measures
Name Time Method The primary outcome of this proposal will be the identification of B-type Natriuretic Peptide signal peptide (BNP-SP) as a novel, specific biomarker of acute cardiac injury. For each blood sample, we will measure plasma BNP-SP as well as the standard serial biomarker concentrations of troponin, creatine kinase and myoglobin.[Blood samples will be takn on admission, then at 0.5, 1, 2, 4, 8, 12, 24, 48 and 72 hours, pre-discharge and 1 month post discharge]
- Secondary Outcome Measures
Name Time Method The secondary outcome will be the potential identification of a new class of circulating biomarkers that may have diagnostic potential in pathophysiology. For each blood sample, we will measure plasma BNP-SP as well as the standard serial biomarker concentrations of troponin, creatine kinase and myoglobin.[Blood samples will be takn on admission, then at 0.5, 1, 2, 4, 8, 12, 24, 48 and 72 hours, pre-discharge and 1 month post discharge]
