Plaque build-up often doesn’t cause symptoms, but it can block blood flow to vital organs like your heart. Coronary artery disease occurs when atherosclerosis affects the arteries supplying ...
Dr. Ruthmann says thinking of an artery like a hollow pipe can help people understand what "clogged arteries" mean. "Healthy arteries have smooth inner walls without any blockages within the ...
Coronary artery disease develops when the arteries that supply your heart become clogged with a fatty substance called plaque. The build-up of plaque is also called atherosclerosis.
The thrombus then travels downstream to other blood vessels, where the blood clot may partially or completely block blood flow. If the blood flow is completely blocked, cell deaths occur due to the lack of oxygen supply to nearby cells, resulting in necrosis. [82] The narrowing or obstruction of blood flow can occur in any artery within the body.
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
[1] [2] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia. [1] Depending on the extent of ischemia, symptoms of arterial occlusion range from simple soreness and pain that can be relieved with rest, [3] to a lack of sensation or paralysis that could require amputation. [3]
Those symptoms can also come as a result of a coronary artery spasm, which occurs when an artery in the heart squeezes shut. Clogged arteries can cause those events, as well. 4.
In treating renal artery disease, a 2014 study indicates that balloon angioplasty can improve diastolic blood pressure and potentially reduce antihypertensive drug requirements. [30] In the case of peripheral artery disease, treatment to prevent complications is important; without treatment, sores or gangrene (tissue death) may occur. [citation ...
