Introduction: Previous observation identified both hypotension and arterial aging, indexed as Pulse Wave Velocity (PWV), as significant determinants of cognitive decline in older subjects.
Aim: To investigate the role of PWV as a determinant of hypotension in older patients.
Methods: A cohort of 344 subjects came to our Outpatient Clinic, free of cancer, acute myocardial infarction or stroke, atrial fibrillation, renal, hepatic or cardiac failure, secondary hypertension, or thyroid disease.
Results: Hypotension occurred in 49% of participants. SBP levels (OR 0.79, 95% CI 0.67-0.84, p < 0.01), PWV (OR 0.86, 95% CI 0.77-0.94, p < 0.01), and use of beta-blockers (OR 2.42, 95% CI 1.09-5.36, p < 0.05), were independent determinants of the risk of hypotension.
Conclusions: Hypotension is a quite common phenomenon in older subjects. Its prevention requires a more accurate management of hypertension aimed at better identifying which older subjects in whom intensive BP control may be harmful and those who may benefit from it.

Brachial-Ankle Pulse Wave Velocity Reflects Regional Arterial Stiffness and Distensibility in Patients with Abdominal Aortic Aneurysm.

We investigated the association between brachial-ankle pulse wave velocity (PWV) and arterial stiffness and distensibility in the aneurysmal sac of abdominal aortic aneurysm (AAA). Data from 49 patients with AAA from June 2020 to November 2022 at Tokyo Medical University Hospital were retrospectively analyzed. Brachial-ankle PWV (cm/s) was obtained via an automated oscillometric method.

Sexual Dimorphism in the Downregulation of Extracellular Matrix Genes Contribute to Aortic Structural Stiffness in Female Mice.

The contribution of sex hormones to cardiovascular disease, including arterial stiffness, is established; however, the role of sex chromosome interaction with sex hormones, particularly in women, is lagging. Arterial structural stiffness depends on the intrinsic properties and transmural wall geometry that comprise a network of cells and extracellular matrix (ECM) proteins expressed in a sex-dependent manner. In this study, we used four-core genotype (FCG) mice to determine the relative contribution of sex hormones versus sex chromosomes or their interaction with arterial structural stiffness.

Unlabelled: Neuroblastoma (NB) is a highly vascularized pediatric tumor arising from undifferentiated neural crest cells early in life, exhibiting both traditional endothelial-cell-driven vasculature and an intriguing alternative vasculature. The alternative vasculature can arise from cancer cells undergoing transdifferentiation into tumor-derived endothelial cells (TEC), a trait associated with drug resistance and tumor relapse. The lack of effective treatments targeting NB vasculature primarily arises from the challenge of establishing predictive in vitro models that faithfully replicate the alternative vasculature phenomenon.
