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]
Widow maker is an alternative name for the anterior interventricular branch of the left coronary artery. [9] [3] The name widow maker may also apply to the left coronary artery [10] or severe occlusions to that artery. [11] [12] This term is used because the left main coronary and/or the left anterior descending supply blood to large areas of ...
Coronary artery disease is characterized by heart problems that result from atherosclerosis. [34] Atherosclerosis is a type of arteriosclerosis which is the "chronic inflammation of the arteries which causes them to harden and accumulate cholesterol plaques (atheromatous plaques) on the artery walls". [35]
Symptoms include chest pain or angina, shortness of breath, and fatigue. [6]A completely blocked coronary artery will cause a heart attack. [6] Common heart attack symptoms include chest pain or angina, pain or discomfort that spreads to the shoulder, arm, back, neck jaw, teeth or the upper belly, cold sweats, fatigue, heartburn, nausea, shortness of breath, or lightheadedness.
Atherosclerosis of a coronary artery leads to coronary artery disease (CAD). Atherosclerosis is a broad term referring to loss of elasticity of arteries and more specific terms exist — arteriosclerosis and arteriolosclerosis — to narrow which arteries are diseased and can easily be confused due to similar spelling. Overall, atherosclerosis ...
Historically, vascular anomalies have been labeled with descriptive terms, according to the food they resembled (port wine, strawberry, cherry, salmon patch). This imprecise terminology has caused diagnostic confusion, blocked communication and even caused incorrect treatment, as it does not differentiate between various vascular anomalies. [4]
a history of long-term intravenous therapy [1] (for air embolism) Bone fracture (for fat embolism) [4] A septal defect of the heart makes it possible for paradoxical embolization, which happens when a clot in a vein enters the right side of the heart and passes through a hole into the left side. The clot can then move to an artery and cause ...
These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart muscle. These relatively narrow vessels are commonly affected by atherosclerosis and can become blocked, causing angina or myocardial infarction (a.k.a., a heart attack). The coronary arteries that run deep ...
