Cardiac troponin is
equally important in the area of risk stratification, where increases clearly hold prognostic significance with contemporary cardiac troponin assays.
In a multivariate analysis, an elevated cardiac troponin I
value upon admission was the most powerful predictor of in-hospital mortality, he said.
 Nonstandard abbreviations: CK, creatine kinase; RI, reference interval; cTnT, cardiac troponin T; hs-cTnT, high-sensitivity cTnT; cTnI, cardiac troponin I
; hs-cTnI, high-sensitivity cTnI; CMR, cardiac magnetic resonance imaging; MADD, multiple acyl-CoA dehydrogenase deficiency.
The Randomized Assessment of Treatment using Panel Assay of Cardiac markers (RATPAC) trial randomly assigned patients to standard assessment including serial troponin testing or point of care testing for CKMB, myoglobin, and troponin I
on arrival and at 90 min (37).
The patients with an elevated troponin I
level were older, with a mean age of 72 years, compared with a mean age of 66 among the troponin I-negative patients.
To conclude, Point of care cardiac troponin I
helps to differentiate between cardiogenic and non-cardiogenic dyspnoea during an emergency especially when other diagnostics are not feasible with decompensating patient.
Association of high-sensitivity cardiac troponin I
concentration with cardiac outcomes in patients with suspected acute coronary syndrome.
False-positive troponin I
attributed to a macrocomplex.
Results: Median value of high sensitivity troponin I
was 4.051ng/ml before re-centrifugation and 3.689 ng/ml after recentrifugation.

with a normal coronary angiogram," Internal Medicine Journal, vol.
For patients with suspected AMI, current guidelines recommend analyzing cardiac troponin I
at admission and then three hours later, to determine if the level warrants admission or discharge.
(1997) The C terminus of cardiac troponin I
is essential for full inhibitory activity and [Ca.sup.2+] sensitivity of rat myofibrils.
