Mechanisms of vascular remodeling in hypertension

JD Humphrey - American journal of hypertension, 2021 - academic.oup.com
Hypertension is both a cause and a consequence of central artery stiffening, which in turn is
an initiator and indicator of myriad disease conditions and thus all-cause mortality. Such …

Differential cell-matrix mechanoadaptations and inflammation drive regional propensities to aortic fibrosis, aneurysm or dissection in hypertension

MR Bersi, R Khosravi, AJ Wujciak… - Journal of The …, 2017 - royalsocietypublishing.org

Excessive adventitial remodeling leads to early aortic maladaptation in angiotensin-induced hypertension

MR Bersi, C Bellini, J Wu, KRC Montaniel… - …, 2016 - Am Heart Assoc
The primary function of central arteries is to store elastic energy during systole and to use it
