angiosclerosis
Pronunciation: AN-jee-oh-skler-OH-sis
Hardening and thickening of arterial walls due to various pathological processes.
Full Definition
A general term describing the pathological hardening and loss of elasticity in arterial walls, encompassing various forms of vascular sclerosis. This condition reduces vessel compliance and can lead to increased systolic pressure and decreased diastolic filling. Angiosclerosis is distinguished from atherosclerosis by being a broader category that includes arteriosclerosis, arteriolosclerosis, and Mönckeberg's sclerosis, not just atherosclerotic plaque formation.
Usage
Usage note: Broader term than atherosclerosis; avoid using interchangeably with specific types of arterial hardening.
In Context
- "Age-related angiosclerosis contributed to the patient's elevated pulse pressure." — Clinical assessment
