Sensitive Cardiac Troponin Assays: Myth and Magic or a Practical Way Forward?
Cardiac troponins (cTn) are considered to be the ‘gold standard’ biomarkers for the diagnosis of acute coronary syndrome (ACS) a pathological spectrum which includes cardiac ischemia, angina, myocardial infarction and ultimately cardiac failure. The growing evidence base for the diagnostic and prognostic use of cTn in ACS has resulted in a universal redefinition of acute myocardial infarction (AMI). A diagnosis of AMI includes the detection of an elevated cTn (or CK-MB) with at least one measurement within 24 hours of the cardiac episode being >upper 99th percentile of a reference population, in conjunction with evidence of myocardial ischemia. A number of high sensitivity immunoassays with claims of superior imprecision and a definable 99th percentile have been produced. Clinically, these have two important impacts. First, there is a drive to change the values into whole numbers by the application of a unit change which carries the scope for confusion. Secondly, the near-normal Gaussian distribution of sensitive cTn in healthy subjects will increase the frequency of cTn positivity in the non-ACS population. The problem is to decipher if such minor elevations in cTn are of clinical concern. What is certain is that AMI remains a clinical not a biochemical diagnosis and the interpretation of cTn concentrations should be made according to the clinical context.

The Use of Biochip Cardiac Array Technology for Early Diagnosis of Acute Coronary Syndromes
Serum troponin is the best biomarker for the diagnosis of acute coronary syndrome, but it takes considerable time before a definitive diagnosis is available. The purpose of this study was to evaluate whether a multimarker approach, using the biochip cardiac array, would facilitate the early diagnosis. Serum biomarkers were determined on admission (≤6 hrs) and after 6 hours in 42 patients suspected for ACS. Cardiac troponin I was measured by a sensitive assay (STATcTnI) and cardiac markers (H-FABP, myoglobin, cTnI, CK-MB mass, carbonic anhydrase III) were assayed with the use of Biochip Array Technology. STATcTnI concentrations, within the first 6 hours, were elevated >99th percentile for the reference population in 83.3% of subjects, but none reached the cut-off for AMI. On admission H-FABP was the only marker with 90.5% sensitivity in all ACS cases and 100% sensitivity in STEMI/NSTEMI patients. The sensitivity of myoglobin at presentation was 71.4% in ACS, however, combined sensitivity of myoglobin and H-FABP reached 95.2%. Lowering the cut-off for cTnI allowed early diagnosis (≤6 hrs) in only 26.2% of ACS patients and 95.2% after the next 6 hours. In unstable angina the cardiac panel was not sufficiently accurate for early risk stratification. In conclusion, testing for both markers, H-FABP and sensitive cardiac troponin, available with the cardiac array may facilitate the early detection of myocardial injury in clinical practice.

in plasma, but H-FABP is released rapidly upon the onset of acute myocardial infarction (AMI) ( 2 ). This increase in H-FABP can be detected as early as 30 min following the onset of AMI, and the H-FABP concentration typically peaks within 6–8 hours after symptom onset. H-FABP as a biomarker offers high sensitivity across the full spectrum of acute coronary syndrome (ACS) ( 3 , 4 , 5 ). The combination of high sensitivity and early specificity of H-FABP makes it a promising biomarker for early diagnosis and treatment of AMI and ACS that could be superior to the
