Angina Pectoris Introduction

Home/Coronary Heart Disease/Angina Pectoris Introduction

‘Angina’ is a Greek word which means strangulation. Pectoris on the other hand is derived from the Latin word ‘pector’ which means chest. Angina therefore refers to chest pain or discomfort (like heaviness, tightness, or a squeezing/ burning sensation) due to insufficient blood supply (hence oxygen) to the heart muscles. It is typically precipitated by exertion and relieved by taking rest or anti-anginal drugs. The usual site of pain is the centre of the chest  but it may also be felt (radiation) in the left shoulder, upper arm, wrist, neck or jaw. The pain usually subsides within five minutes .
