Endothelial dysfunction may be involved in the development of atherosclerosis [5] [6] [7] and may predate vascular pathology. [ 5 ] [ 8 ] Endothelial dysfunction may also lead to increased adherence of monocytes and macrophages , as well as promoting infiltration of low-density lipoprotein (LDL) in the vessel wall. [ 9 ]
The chronic endothelial injury hypothesis is one of two major mechanisms postulated to explain the underlying cause of atherosclerosis and coronary heart disease (CHD), the other being the lipid hypothesis. Although an ongoing debate involving connection between dietary lipids and CHD sometimes portrays the two hypotheses as being opposed, they ...
The prevention of episodes of SCLS has involved two approaches. The earliest was advocated by the Mayo Clinic, and it recommended treatment with high doses of beta agonists such as terbutaline, phosphodiesterase-inhibitor theophylline, and leukotriene-receptor antagonists montelukast sodium.

Endothelium dysfunction is a prototypical characteristic of vascular disease, which is common in patients with autoimmune diseases such as systemic lupus erythematosus. [20] Further, there is an inverse relationship between age and levels of EPCs. Inverse of endothelial dysfunction also occurs when other risk factors are treated. [21]
FMD is a noninvasive measure of blood vessel health (endothelial dysfunction [5] [6]) which (when low) is at least as predictive of cardiovascular disease as traditional risk factors. [4] [7] [8] Major cardiovascular disease associated with low FMD include cardiac death, myocardial infarction, and stroke. [8]
Microangiopathy (also known as microvascular disease, small vessel disease (SVD) or microvascular dysfunction) is a disease of the microvessels, small blood vessels in the microcirculation. [1] It can be contrasted to macroangiopathies such as atherosclerosis , where large and medium-sized arteries (e.g., aorta , carotid and coronary arteries ...
Circulating endothelial cells (CECs) are endothelial cells that have been shed from the lining of the vascular wall into the blood stream. [1] Endothelial cells normally line blood vessels to maintain vascular integrity and permeability, but when these cells enter into the circulation, this could be a reflection of vascular dysfunction and damage. [2]
Endothelial dysfunction has also been shown to be predictive of future adverse cardiovascular events including stroke, heart disease, and is also present in inflammatory disease such as rheumatoid arthritis, diabetes, and systemic lupus erythematosus. [18] [19] Endothelial dysfunction is a result of changes in endothelial function.
