Betablockers post MI - NICE guidelines

• early after an acute MI, all patients without left ventricular systolic dysfunction or with left ventricular systolic dysfunction (symptomatic or asymptomatic) should be offered treatment with a beta-blocker
• for patients after an MI with left ventricular systolic dysfunction, who are being offered treatment with a beta-blocker, clinicians may prefer to consider treatment with a beta-blocker licensed for use in heart failure
• beta-blockers should be continued indefinitely after an acute MI
• after a proven MI in the past, all patients with left ventricular systolic dysfunction should be offered treatment with a beta-blocker whether or not they have symptoms, and those with heart failure plus left ventricular systolic dysfunction should be managed in line with 'Chronic heart failure' guidance
• after a proven MI in the past, patients with preserved left ventricular function who are asymptomatic should not be routinely offered treatment with a beta-blocker, unless they are identified to be at increased risk of further cardiovascular events, or there are other compelling indications for beta-blocker treatment
• beta-blockers should be initiated as soon as possible when the patient is clinically stable and titrated upwards to the maximum tolerated dose.
