J Am Coll Cardiol 2018 Dec;72(24):3158-3176

Heidelberg University Hospital, Heidelberg, Germany; Department of Cardiology, McGill University Health Centre, Montreal, Canada; Department of Diagnostic Radiology, McGill University Health Centre, Montreal, Canada. Electronic address:

This JACC Scientific Expert Panel provides consensus recommendations for an update of the cardiovascular magnetic resonance (CMR) diagnostic criteria for myocardial inflammation in patients with suspected acute or active myocardial inflammation (Lake Louise Criteria) that include options to use parametric mapping techniques. While each parameter may indicate myocardial inflammation, the authors propose that CMR provides strong evidence for myocardial inflammation, with increasing specificity, if the CMR scan demonstrates the combination of myocardial edema with other CMR markers of inflammatory myocardial injury. This is based on at least one T2-based criterion (global or regional increase of myocardial T2 relaxation time or an increased signal intensity in T2-weighted CMR images), with at least one T1-based criterion (increased myocardial T1, extracellular volume, or late gadolinium enhancement).

Myocardial infarction (MI) is a major cause of death worldwide. Here, we identify the macrophage MR (mineralocorticoid receptor) as a crucial pathogenic player in cardiac wound repair after MI. Seven days after left coronary artery ligation, mice with myeloid cell-restricted MR deficiency compared with WT (wild type) controls displayed improved cardiac function and remodeling associated with enhanced infarct neovascularization and scar maturation.

Plasma Concentrations of Myeloid-Derived Growth Factor in Healthy Individuals and Patients with Acute Myocardial Infarction as Assessed by Multiple Reaction Monitoring-Mass Spectrometry.

Anal Chem 2018 Dec 13. Epub 2018 Dec 13.

Myeloid-derived growth factor (MYDGF in humans, Mydgf in mice) is a secreted protein with previously unknown biological functions. In a recent study, Mydgf was shown to mediate cardiac repair after acute myocardial infarction (MI) in mice. Lack of a sensitive assay to measure MYDGF in the circulation has hampered its further investigation. Read More

Chitosan/Calcium Silicate Cardiac Patch Stimulates Cardiomyocyte Activity and Myocardial Performance after Infarction by Synergistic Effect of Bioactive Ions and Aligned Nanostructure.

ACS Appl Mater Interfaces 2018 Dec 13. Epub 2018 Dec 13.

Cardiac tissue engineering (CTE) remains a great challenge to construct a cell-inductive scaffold which has positive effects on cardiac cell behaviors and cardiac tissue repair. In this study, we for the first time demonstrated that Si ions evidently stimulated the expression of cardiac specific genes and proliferation of neonatal rat cardiomyocytes (NRCMs) at concentration ranges of 0.13 ~ 10.

The use of vascular endothelial growth factor inhibitors such as sorafenib is limited by a risk of severe cardiovascular toxicity. A 28-year-old man with acute myeloid leukemia treated with prednisone, tacrolimus, and sorafenib following stem cell transplantation presented with severe bilateral lower extremity claudication. The patient was discharged against medical advice prior to finalizing a cardiovascular evaluation, but returned 1 week later with signs suggestive of septic shock. Read More

The explosion of stem cell research in the past several years has made its presence known in the field of cardiology and has been recently tasked with solving one of the largest health problems to afflict humanity: cardiovascular disease (CVD). Although stem cell therapy has shown glimmers of promise, significant problems remain that need to be addressed if these therapies are to ever find true success. One way to achieve this success is to take engineering principles and apply them to fabricate engineered cardiac tissues, composed of the aforementioned therapeutic stem cells and biomaterials to bolster the tissue's reparative capacity.

From bedside to bench and back again: translational studies of mechanical unloading of the left ventricle to promote recovery after acute myocardial infarction.

F1000Res 2018 27;7. Epub 2018 Nov 27.

Cardiovascular Research Center, Mount Sinai School of Medicine, New York, New York, USA.

Heart failure is a major cause of global morbidity and mortality. Acute myocardial infarction (AMI) is a primary cause of heart failure due in large part to residual myocardial damage despite timely reperfusion therapy. Since the 1970's, multiple preclinical laboratories have tested whether reducing myocardial oxygen demand with a mechanical support pump can reduce infarct size in AMI. Read More

Increased expression of the Tribbles pseudokinase 1 gene () is associated with lower plasma levels of LDL cholesterol and triglycerides, higher levels of HDL cholesterol and decreased risk of coronary artery disease and myocardial infarction. We identified a class of tricyclic glycal core-based compounds that upregulate expression in human HepG2 cells and phenocopy the effects of genetic overexpression as they inhibit expression of triglyceride synthesis genes and ApoB secretion in cells. In addition to predicted effects related to downregulation of VLDL assembly and secretion these compounds also have unexpected effects as they upregulate expression of LDLR and stimulate LDL uptake.
