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 often brought on by exercise and activity and gets better with rest. When the body requires the heart to pump more blood, the heart muscle is asked to do more work and that can cause it to outstrip its energy supply. When the body rests, angina should start to subside.
