We tend to think of angina as less serious than an acute myocardial infarction (AMI). But this study suggests that both conditions have a similar prognosis. Similar numbers of people will have a further AMI or need intervention such as a coronary artery bypass graft. And over a 4.5 year follow-up, people with angina have more physical impairment than those who have had an AMI. The implication is that we should be focused in our efforts to minimise risk factors in people with angina, not wait for them to have a heart attack.
