'angina' originates from Latin, specifically the word 'angere,' where 'angere' meant 'to strangle or choke.'

'angina' changed from the Latin word 'angina' (meaning throat inflammation or strangling) and eventually became the modern English word 'angina.'

Initially, it meant 'throat inflammation or choking,' but over time it evolved into its current meaning of 'chest pain due to reduced blood flow to the heart.'
