Pole of Cardiovascular Research, Institut de Recherche Expérimentale et Clinique and Division of Cardiology, Cliniques Universitaires Saint-Luc, Université Catholique de Louvain, Brussels, Belgium.

Fibromuscular dysplasia (FMD) is a non-atherosclerotic vascular disease that may involve medium-sized muscular arteries throughout the body. The pathogenesis of FMD remains poorly understood, but a combination of genetic and environmental factors may be involved. The majority of FMD patients are women, but men may have a more progressive disease, especially when smoking. Read More

KLF2 Mediates the Suppressive Effect of Laminar Flow on Vascular Calcification by Inhibiting Endothelial BMP/SMAD1/5 Signaling.

Circ Res 2021 Jun 23. Epub 2021 Jun 23.

School of Biomedical Sciences, The Chinese University of Hong Kong, CHINA.

Vascular calcification in arterial intima is closely associated with atherosclerosis. Endothelial cells (ECs) sense blood flow and respond to the mechanical cues generated by different flow patterns. Laminar flow (LF) induces an anti-atherosclerotic EC phenotype whereas disturbed flow (DF) exerts an atheroprone effect. Read More

Is There a Role of Coronary CTA in Primary Prevention? Current State and Future Directions.

Curr Atheroscler Rep 2021 Jun 19;23(8):44. Epub 2021 Jun 19.

Johns Hopkins Ciccarone Center for the Prevention of Heart Disease, Baltimore, MD, USA.

Purpose Of Review: Information on subclinical atherosclerosis burden provides prognostic information on atherosclerotic cardiovascular disease (ASCVD) risk beyond what can be achieved by traditional risk factors alone and may therefore improve allocation of preventive treatment in primary prevention. The purpose of this review is to discuss the potential role and value of assessing subclinical atherosclerosis using coronary artery calcium (CAC) versus computed tomography angiography (CTA) among asymptomatic patients in the context of current primary prevention cholesterol guidelines.

Recent Findings: Since 2013, primary prevention cholesterol guidelines have lowered the treatment threshold for initiating statin therapy resulting in high statin eligibility and sensitivity for detecting ASCVD events. Read More

Lipid biomarkers in statin users with coronary artery disease annotated by coronary computed tomography angiography.

Sci Rep 2021 Jun 18;11(1):12899. Epub 2021 Jun 18.

Istituto di Fisiologia Clinica-CNR, via Giuseppe Moruzzi 1, 56124, Pisa, Italy.

Molecular markers are suggested to improve the diagnostic and prognostic accuracy in patients with coronary artery disease (CAD) beyond current clinical scores based on age, gender, symptoms and traditional risk factors. In this context, plasma lipids are emerging as predictors of both plaque composition and risk of future events. We aim to identify plasma lipid biomarkers associated to CAD indexes of stenosis severity, plaque lipid content and a comprensive score of CAD extent and its risk. Read More

Extensive and balanced reduction of myocardial blood flow in patients with suspected obstructive coronary artery disease: 15O-water PET study.

Int J Cardiol 2021 Jun 15. Epub 2021 Jun 15.

Turku PET Centre, University of Turku, Turku, Finland; Department of Clinical Physiology, Nuclear Medicine and PET, Turku University Hospital, Turku, Finland.

Background: Detection of obstructive coronary artery disease (CAD) by stress myocardial perfusion imaging (MPI) is conventionally based on relative differences in perfusion. This may lead to either underestimation of the extent of myocardial ischemia, or the ischemia might be completely missed in case of balanced perfusion reduction. Using absolute quantification of myocardial blood flow (MBF) by positron emission tomography (PET), we evaluated how common are extensive and balanced myocardial perfusion abnormalities in symptomatic patients with suspected obstructive CAD.

Left atrial function by cardiac computed tomography is a predictor of heart failure and cardiovascular death.

Eur Radiol 2021 Jun 16. Epub 2021 Jun 16.

Cardiology Department, Rambam Health Care Campus, Haaliya Street, 31096, Haifa, Israel.

Coronary Artery Calcification as a Marker for Coronary Artery Stenosis: Comparing Kidney Failure to the General Population.

Kidney Med 2021 May-Jun;3(3):386-394.e1. Epub 2021 Apr 20.

Department of Nephrology, Amsterdam UMC, Amsterdam Cardiovascular Sciences, Amsterdam.

Rationale & Objective: The presence of calcified plaques in the coronary arteries is associated with cardiovascular mortality and is a hallmark of chronic kidney failure, but it is unclear whether this is associated with the same degree of coronary artery stenosis as in patients without kidney disease. We compared the relationship of coronary artery calcification (CAC) and stenosis between dialysis patients and patients without chronic kidney disease (CKD).
