Abstract
Coronary artery disease is the commonest cause of heart failure in the western world accounting for up w x to 60% of cases 1 . Although the benefits of coronary artery surgery in patients with angina or evidence of exercise-inducible ischaemia have been defined, the role of revascularisation in patients with postischaemic heart failure remains unclear. There is a tendency to equate LV dysfunction with heart failure, and although the two conditions are often associated, there are many patients with markedly depressed LV function without significant heart failure. From a clinical point of view, therefore, we must distinguish Ž . between two possible clinical scenarios: 1 patients with severe LV dysfunction and predominant sympŽ . toms of angina; and 2 patients with severe LV dysfunction and predominant symptoms of heart failure.
