The figures show endothelial microparticles (EMPs), as defined by CD31+/41−, CD62e+, and CD144+ surface markers (Fig. 1), and vascular hemodynamic parameters including office and central blood pressure, heart rate, aortic augmentation index, pulse wave velocity, flow-mediated dilation, nitroglycerin-mediated dilation, brachial artery diameter, hyperemic wall shear stress, and laser Doppler perfusion of the cutaneous microcirculation (Fig.2) of normotensive and hypertensive patients with and without CAD. This evidence concerns the gene PECAM1 and coronary artery disorder.
