Pulse wave analysis as a tool to assess endothelial function following lipid lowering intervention in hypercholesterolemia.

Background: Pulse wave analysis (PWA) assesses endothelial dependent vasodilation (EDV) via the change in augmentation index (AIx) and has been used as a tool to assess endothelial function. However, its effectiveness in assessing the response to lipid lowering treatment has not been evaluated. The study aimed to describe and correlate the change in EDV following lipid lowering intervention in patients with hypercholesterolemia.

Endothelial Microparticles as Potential Biomarkers in the Assessment of Endothelial Dysfunction in Hypercholesterolemia.

Background and Objectives: Endothelial microparticles (EMP) particularly CD31+/42−/AV+, CD144+/AV+ and CD62e+/AV+ have been reported as having increased in cardiovascular-related diseases, making them potential biomarkers for endothelial dysfunction. This study aimed to compare these EMPs in patients with hypercholesterolemia and healthy controls and to correlate their levels with endothelium-dependent vasodilation (EDV) assessed via pulse wave analysis (PWA); an established method of assessing endothelial function. Materials and Methods: EMPs from 88 subjects (44 hypercholesterolemia patients and 44 controls) were quantified from whole blood using flow cytometry analysis.

Systemic and coronary levels of CRP, MPO, sCD40L and PlGF in patients with coronary artery disease.

Background: Biomarkers play a pivotal role in the diagnosis and management of patients with acute coronary syndrome. This study aimed to investigate the differences in level of several biomarkers, i.e.

Prevalence of beta-2 adrenergic receptor (beta 2 AR) polymorphisms and its influence on a model used to assess endothelial function using pulse wave analysis (PWA).

Background: Pulse wave analysis (PWA) combined with beta(2)-agonist challenge has recently been used to assess endothelial function. beta-2 adrenergic receptor (beta(2)AR) polymorphisms may affect response to beta(2)-agonist. We determined whether beta(2)AR polymorphisms influence endothelial response in our model using PWA and salbutamol.
