Angina Pectoris

INTRODUCTION

‘Angina’ is a Greek word which means strangulation and pectoris is derived from Latin word ‘pector’ which means chest. Angina therefore refers to chest pain or discomfort (like heaviness, tightness, 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 central chest  but it may also be felt (radiation) in left shoulder, upper arm, wrist, neck or jaw. The pain usually subsides within five minutes.
