Key result
D-dimer demonstrated high diagnostic accuracy for myocardial infarction with an AUC of 0.844, yielding a sensitivity of 82.5% and specificity of 65.0% at a cut-off of 425 ng/ml.
Why the study?
The role of D-dimer and H-FABP as diagnostic markers in myocardial infarction remains uncertain.
Are D-dimer and H-FABP levels significantly elevated in patients with myocardial infarction compared to controls?
Case-Control (n=80)
No
Are D-dimer and H-FABP levels significantly elevated in patients with myocardial infarction compared to controls?
Absolute Event Rate: 0.844% vs 0.825%
D-dimer and H-FABP levels are significantly elevated in patients with myocardial infarction compared to controls, suggesting potential diagnostic utility.
D-dimer may complement troponin for early MI diagnosis; leaves open need for larger prospective validation before routine adoption.

Abdulsattar et al. (2023) conducted a case-control in Myocardial Infarction (n=80). D-dimer and H-FABP vs. Healthy controls / Cardiac Troponin I was evaluated on Diagnostic accuracy (Area Under the Curve) for myocardial infarction. D-dimer demonstrated high diagnostic accuracy for myocardial infarction with an AUC of 0.844, yielding a sensitivity of 82.5% and specificity of 65.0% at a cut-off of 425 ng/ml.
