Dipping phenomena is defined as nocturnal BP fall >10% during 24-h ambulatory blood pressure (BP) monitoring (ABPM) which carries a favorable cardiovascular risk (CVR) prognosis due to reduced 24-h hypertension burden. To date, extreme dipping phenotype (defined as BP decrease ≥20%) has led to controversial prognostic results regarding CVR. We aimed to explore hypertension-mediated organ damage (HMOD) in extreme dippers compared to the other dipping phenotypes (nondipping, dipping).

Loss of endothelial glycocalyx (EG) integrity, as part of the endothelium, represents endothelial dysfunction. The authors aimed to investigate the role of increased HDL cholesterol levels (HDL-C), which usually are considered protective against CV disease, in aortic stiffness and endothelial integrity in middle-aged treated hypertensive patients regarding smoking habit.

Endothelial dysfunction indicates target organ damage in hypertensive patients. The integrity of endothelial glycocalyx (EG) plays a vital role in vascular permeability, inflammation and elasticity, and finally to cardiovascular disease. The authors aimed to investigate the role of increased HDL cholesterol (HDL-C) levels, which usually are considered protective against cardiovascular disease, in EG integrity in older hypertensive patients.
