Key result
A single cardiac troponin T measurement at CCU discharge after AMI significantly correlated with peak CK-MB concentrations (r=0.76, P<0.001) and perfusion defect size at SPECT (r=0.62, P<0.001).
Why the study?
Does a single measurement of cardiac troponin T at CCU discharge correlate with infarct size and left ventricular function in patients with acute myocardial infarction?
Observational (n=65)

Effect estimate: r = 0.76
p-value: p=<0.001
A single cTnT measurement at CCU discharge after AMI correlates well with infarct size and LV function, providing a useful noninvasive prognostic estimate.
No takes yet. Share an insight, caveat, or question.
May support discharge cTnT as noninvasive infarct size surrogate after AMI; leaves open added prognostic value beyond existing markers.
Panteghini et al. (2002) conducted an observational in Acute myocardial infarction (n=65). Single-point cardiac troponin T (cTnT) measurement vs. CK-MB peak concentrations and SPECT myocardial perfusion was evaluated on Correlation between cTnT and peak CK-MB concentrations (r = 0.76, p=<0.001). A single cardiac troponin T measurement at CCU discharge after AMI significantly correlated with peak CK-MB concentrations (r=0.76, P<0.001) and perfusion defect size at SPECT (r=0.62, P<0.001).
