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 ]
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 ...
Antioxidants may have beneficial effects on diabetic complications by reducing blood pressure, attenuating oxidative stress and inflammatory biomarkers, improving lipid metabolism, insulin-mediated glucose disposal, and by enhancing endothelial function. [83] [96] [97] Vitamin C has been proposed to induce beneficial effects by two other ...
This endothelial dysfunction leads to impaired myocardial blood flow reserve as evidence by echocardiography. [10] About 50% of diabetics with diabetic cardiomyopathy show pathologic evidence for microangiopathy such as sub-endothelial and endothelial fibrosis, compared to only 21% of non-diabetic heart failure patients. [11]
The primary cause of microvascular angina is unknown, but factors apparently involved are endothelial dysfunction and reduced flow (perhaps due to spasm) in the tiny "resistance" blood vessels of the heart. [18] Since microvascular angina is not characterized by major arterial blockages, it is harder to recognize and diagnose. [19] [20] [21]
Coronary artery bypass grafting (CABG): A bypass surgery improves blood flow to your heart by taking another blood vessel from somewhere else in your body and using it to create a new passage for ...
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.
Microvascular angina (MVA), previously known as cardiac syndrome X, [1] also known as coronary microvascular dysfunction (CMD) or microvascular coronary disease is a type of angina (chest pain) with signs associated with decreased blood flow to heart tissue but with normal coronary arteries. [2] [3]
