    EDITOR,—Several large studies have shown that angiotensin converting enzyme inhibitors reduce mortality in patients with left ventricular dysfunction after acute myocardial infarction.1 2 However, left ventricular dysfunction after acute myocardial infarction is difficult to detect on clinical examination, and McMurray and Rankin devised a clinical algorithm to help doctors.3 This algorithm emphasises the importance of a Q wave anterior infarction, previous acute myocardial infarction, and clinical evidence of left ventricular failure, but its accuracy has not been assessed in clinical practice.

    We have assessed the …
