Angina pectoris is a common symptom, usually reflecting obstructive coronary
artery disease (CAD). As the location and extent of the coronary disease, along
with the quality of left ventricular (LV) function, determine prognosis it is important
to make an accurate diagnosis as soon as possible. Management is designed
not only to relieve symptoms and thereby improve the quality of life, but also, by
appropriately timed non-invasive and invasive investigations, to identify those at
most risk so that we can select optimal therapy which will also lengthen life.
