Background: Biomarkers simplifying the diagnostic workup by discriminating between non-ST-segment-elevation myocardial infarction (NSTEMI) and infarct-like myocarditis are an unmet clinical need.
Methods And Results: A total of 105 subjects were categorized into groups as follows: ST-segment-elevation myocardial infarction (n=36), NSTEMI (n=22), infarct-like myocarditis (n=19), cardiomyopathy-like myocarditis (n=18), and healthy control (n=10). All subjects underwent cardiac magnetic resonance imaging, and serum concentrations of matrix metalloproteinase-1 (MMP-1) and procollagen type I carboxy terminal propeptide (PICP) were measured.
Article Synopsis
- A population study of 1,064 participants found that 23% had unrecognized myocardial scar (UMS), indicating a significant prevalence of this condition in people without known heart disease.
- UMS was mostly non-ischemic (89%), often affecting the basal inferolateral left ventricle, and was linked to lower left ventricular ejection fraction (LVEF) and higher LV mass.
- Specifically, ischemic UMS was associated with lower LVEF, higher LV mass, and a history of diabetes, highlighting the importance of assessing UMS for better understanding cardiac health.
Feature tracking cardiovascular magnetic resonance reveals recovery of atrial function after acute myocarditis.
Int J Cardiovasc Imaging

Follow-up after acute myocarditis is important to detect persisting myocardial dysfunction. However, recovery of atrial function has not been evaluated after acute myocarditis so far. Thirty-five patients with strictly defined acute myocarditis underwent cardiovascular magnetic resonance (CMR, 1.

However, the primary tool for differentiating non-ST elevation myocardial infarction (NSTEMI) from myocarditis is still a visual assessment of conventional signal-intensity-based images. This study aimed at analyzing the ability of parametric compared to conventional techniques to visually differentiate ischemic from non-ischemic myocardial injury patterns.

We aimed at describing global and segmental myocardial strain patterns and a potential association with the presence of focal myocardial scarring in DCM patients by CMR-FT.
Methods: Thirty-nine patients with DCM and reduced left ventricular (LV) ejection fraction (mean 21±8%) underwent CMR including standard cine steady-state free precession (SSFP) sequences and late gadolinium enhancement (LGE).
