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.
Obstructive coronary artery disease which is the commonest cause of angina can be due to smoking, high blood pressure, a high blood cholesterol level, lack of exercise, obesity and diabetes.he pain of angina can be very difficult to describe. It is often described not so much as a pain, but as a squeezing, tight feeling in the chest. The feeling is also often mistaken for indigestion. The pain can radiate from the centre of the chest to the left shoulder and down the left arm.
