The circumflex branch of left coronary artery (also known as the left circumflex artery or circumflex artery [citation needed]) is a branch of the left coronary artery. It winds around the left side of the heart along the atrioventricular groove (coronary sulcus). It supplies the posterolateral portion of the left ventricle. [1]
Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]
Each year in the United States, according to the Centers for Disease Control and Prevention (CDC), about 735,000 people have a heart attack and 610,000 people die of coronary heart disease (CHD).
Numbness and tingling in an arm or leg [1] [2] Paleness [1] [2] of the skin of the arm or leg; Muscle weakness of an arm or leg, [1] [2] possibly to the grade of paralysis [2] Later symptoms are closely related to infarction of the tissue supplied by the occluded artery: Blisters of the skin in the affected area [1] Shedding of skin ...
Coronary ischemia can have serious consequences if it is not treated. Plaques in the walls of the coronary arteries can rupture, resulting in occlusion of the artery and deprivation of blood flow and oxygen to the heart muscle, resulting in cardiac cell death. [9] This is known as myocardial infarction. [9]
Coronary arteries are vessels supplying blood and nutrients to the heart muscle (). [1]Coronary arteries arise from ostia, openings of the aorta (the largest artery in the human body) at the upper third or middle third of the sinuses of Valsalva (the first part of the big pipe coming off the main pumping chamber).
Peripheral arteries, which supply blood to the legs, arms, and pelvis, also experience marked narrowing due to plaque rupture and clots. Symptoms of the narrowing are pain and numbness within the arms or legs. Another significant location for plaque formation is the renal arteries, which supply blood to the kidneys.
[citation needed] The left coronary artery typically runs for 10–25 mm, then bifurcates into the left anterior descending artery, and the left circumflex artery. [ 1 ] The part that is between the aorta and the bifurcation only is known as the left main artery (LM), while the term "LCA" might refer to just the left main, or to the left main ...
