leprechauns definition In the folklore of Ireland, little men who resemble elves. Supposedly, leprechauns can reveal â but only to someone clever enough to catch them â the location of buried treasure, typically a crock of gold hidden at the end of the rainbow.
Exertional angina, or stable angina, is a type of chest pain caused by the blockage of blood flow through a coronary artery, or blood vessel around the heart.
Angina is most often caused by narrowing of the coronary arteries because of atherosclerotic heart disease. There may be one or more arteries that are blocked and the amount of pain or other symptom severity is not necessarily related to the number of blood vessels blocked.ome causes for angina are multifactorial. For example, a patient with atherosclerotic heart disease may become acutely ill or injured, where a fever or anemia may compound the inability of narrowed blood vessels to deliver oxygen to heart muscle cells.
