The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart. The two main branches are the left ...
Coronary vasospasm refers to when a coronary artery suddenly undergoes either complete or sub-total temporary occlusion. [1]In 1959, Prinzmetal et al. described a type of chest pain resulting from coronary vasospasm, referring to it as a variant form of classical angina pectoris. [2]
Vasospasm refers to a condition in which an arterial spasm leads to vasoconstriction. This can lead to tissue ischemia (insufficient blood flow) and tissue death . Along with physical resistance, vasospasm is a main cause of ischemia. Like physical resistance, vasospasms can occur due to atherosclerosis.
Seven major factors (i.e. history of out of hospital cardiac arrest [score = 4]; smoking, angina at rest, physically obstructive coronary artery disease, and spasm in multiple coronary arteries [score = 2]; and presence of ST segment elevations on ECG and history of using beta blockers [score = 1]) where assigned the indicated scores ...
Atherosclerosis is the most common cause of stenosis (narrowing of the blood vessels) of the heart's arteries and, hence, angina pectoris. Some people with chest pain have normal or minimal narrowing of heart arteries; in these patients, vasospasm is a more likely cause for the pain, sometimes in the context of Prinzmetal's angina and syndrome X.
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).
Coronary arteries deliver oxygen-rich blood to the heart muscle. [5] Reduced blood flow to the heart associated with coronary ischemia can result in inadequate oxygen supply to the heart muscle. [6] When oxygen supply to the heart is unable to keep up with oxygen demand from the muscle, the result is the characteristic symptoms of coronary ...
The animation shows plaque buildup or a coronary artery spasm can lead to a heart attack and how blocked blood flow in a coronary artery can lead to a heart attack. The most common cause of a myocardial infarction is the rupture of an atherosclerotic plaque on an artery supplying heart muscle.
