Genetic predisposition through single-nucleotide variation (SNV) influences circulatory soluble junctional adhesion molecule-A (sJAM-A) levels in coronary artery disease (CAD) patients. Homozygous carriers of the minor alleles (SNVs rs2774276, rs790056) show enhanced levels of thrombo-inflammatory sJAM-A. Both SNVs and sJAM-A are associated with worse prognosis for recurrent myocardial infarction in CAD patients. Platelet surface-associated JAM-A correlate with platelet activation markers in CAD patients. Activated platelets shed transmembrane-JAM-A, generating proinflammatory sJAM-A and JAM-A-bearing microparticles. Platelet transmembrane-JAM-A and sJAM-A as homophilic interaction partners exaggerate thrombotic and thrombo-inflammatory platelet monocyte interactions. Therapeutic strategies interfering with this homophilic interface may regulate thrombotic and thrombo-inflammatory platelet response in cardiovascular pathologies where circulatory sJAM-A levels are elevated.

Restrictive Versus Liberal Transfusion in Symptomatic Coronary Artery Disease and Myocardial Infarction: A Meta-Analysis of Randomized Controlled Trials.

Division of Cardiology, Ellis Hospital, New York, NY.
Background: In patients with coronary artery disease (CAD) and/or myocardial infarction (MI), anemia is associated with an increased risk of adverse cardiovascular (CV) outcomes. Transfusion goals in such patients remain unclear.
Study Question: A meta-analysis of the available randomized controlled trials (RCTs) was conducted comparing restrictive and liberal transfusion strategies in patients with symptomatic CAD/MI.

Coronary artery disease (CAD) is the leading cause of death worldwide. Acute coronary syndrome (ACS) encompasses a spectrum of diagnoses ranging from unstable angina pectoris to myocardial infarction with and without ST-segment elevation and frequently presents as the first clinical manifestation. It is crucial in this scenario to perform a timely and comprehensive assessment of patients by evaluating the clinical presentation, electrocardiogram and laboratory diagnostics using highly sensitivity cardiac troponin in order to initiate a timely and risk-adapted continuing treatment with immediate or early invasive coronary angiography.

Objectives: The use of deep learning models for quantitative measurements on coronary computed tomography angiography (CCTA) may reduce inter-reader variability and increase efficiency in clinical reporting. This study aimed to investigate the diagnostic performance of a recently updated deep learning model (CorEx-2.0) for quantifying coronary stenosis, compared separately with two expert CCTA readers as references.

The non-observational, international XATOA registry showed that the COMPASS results can be reproduced in clinical practice in patients with coronary artery disease (CAD) and peripheral artery disease (PAD). Here we report patient characteristics and clinical outcomes for the subgroup of German PAD patients of the XATOA registry and compare them to COMPASS PAD patients.

Background: Coronary artery disease (CAD) is a major health problem of atherosclerotic cardiovascular (CV) disease and early intervention is regarded important. Given the proven effect of a lifestyle intervention with nursing telephone counselling and mHealth use in health care, yet the comparisons of both support are lacking, this study is proposed.
Objectives: This study aimed to compare the effects of a coronary artery disease (CAD) support program using a mobile application versus nurse phone advice on exercise amount and physical and psychological outcomes for clients at risk of CAD.
