Article Synopsis
  • This study compares the image quality and methods for measuring infarct size between a new technique called MT-FIDDLE and the standard bright-blood LGE cardiac MRI in patients who had a heart attack (STEMI).
  • The results indicate that MT-FIDDLE provides significantly better subjective image quality, particularly in terms of confidence for infarct segmentation and blood-pool contrast, with a high concordance in infarct volume measurements compared to bright-blood LGE.
  • Ultimately, MT-FIDDLE proved to enhance the ability to differentiate between heart injury (myocardial infarction) and surrounding blood, suggesting it could be a superior imaging method for assessing heart damage after a STEMI.

Relation of plasma neuropeptide-Y with myocardial function and infarct severity in acute ST-elevation myocardial infarction.

Eur J Intern Med

August 2024

University Clinic of Internal Medicine III, Cardiology and Angiology, Medical University of Innsbruck, Anichstrasse 35, A-6020 Innsbruck, Austria. Electronic address:

Article Synopsis
  • The study investigates the link between plasma neuropeptide-Y (NPY) levels and heart muscle function in patients who suffered from a ST-elevation myocardial infarction (STEMI) and were treated with a procedure called primary percutaneous coronary intervention (PCI).
  • Results show that higher NPY levels are connected to poorer heart function indicators, such as lower left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS), as well as larger infarct sizes (IS) and microvascular obstruction (MVO).
  • The findings suggest that elevated NPY levels after a heart attack might be an important marker for evaluating heart damage and recovery prospects, independent of other clinical factors.

Background: Aortic stenosis (AS) is one of the most prevalent valvular heart-diseases in Europe. Currently, diagnosis and classification are not sex-sensitive; however, due to a distinctly different natural history of AS, further investigations of sex-differences in AS-patients are needed. Thus, this study aimed to detect sex-differences in severe AS, especially concerning flow-patterns, via phase-contrast cardiac magnetic resonance imaging (PC-CMR).

Background: Microvascular obstruction (MVO) and intramyocardial hemorrhage (IMH) are well-established imaging biomarkers of failed myocardial tissue reperfusion in patients with ST-segment elevation-myocardial infarction treated with percutaneous coronary intervention. MVO and IMH are associated with an increased risk of adverse outcome independent of infarct size, but whether the size of the culprit lesion vessel plays a role in the occurrence and severity of reperfusion injury is currently unknown. This study aimed to evaluate the association between culprit lesion vessel size and the occurrence and severity of reperfusion injury as determined by cardiac magnetic resonance imaging.

Introduction: Previous analyses have reported the outcomes of transcatheter aortic valve replacement (TAVR) for patients with low-flow, low-gradient (LFLG) aortic stenosis (AS), without stratifying according to the route of access. Differences in mortality rates among access routes have been established for high-gradient (HG) patients and hypothesized to be even more pronounced in LFLG AS patients. This study aims to compare the outcomes of patients with LFLG or HG AS following transfemoral (TF) or transapical (TA) TAVR.
