Study Notes
Atherosclerotic Cardiovascular Disease (ASCVD)
- A group of conditions caused by atherosclerosis that can affect different locations throughout the body
- Examples include coronary artery disease (CAD), peripheral artery disease (PAD), and ischemic stroke
Risk Factors
- Advanced age
- Smoking
- Diabetes mellitus
- Hypertension
- Dyslipidaemia
Pathogenesis of Atherosclerosis
- Precipitated by endothelial damage, leading to inflammation and formation of atheromas in vessel walls
- Chronic stress on the endothelium due to arterial hypertension and turbulence
- Endothelial cell dysfunction leads to invasion of inflammatory cells, adhesion of platelets, and release of inflammatory mediators
- Inflammation of the vessel wall
- Macrophages and smooth muscle cells ingest cholesterol from oxidized LDL, transforming into foam cells
Definition of ASCVD
- An umbrella term for clinical manifestations of atherosclerosis, including:
- Coronary artery disease (CAD)
- Cerebrovascular disease (stroke, TIA, carotid artery stenosis)
- Peripheral artery disease
- History of arterial revascularization
- Abdominal aortic aneurysm, thoracic aortic aneurysm
- Intestinal ischemia
Atherosclerosis and Arteriosclerosis
- Atherosclerosis is a type of arteriosclerosis, characterized by build-up of cholesterol plaques in the tunica intima
- Arteriosclerosis is an umbrella term for arterial wall thickening and elasticity loss with variable pathogenesis
- Other types of arteriosclerosis include Monckeberg arteriosclerosis and arteriolosclerosis (hyaline and hyperplastic)
