Mnemonic

Secondary Prevention After Myocardial Infarction

A mnemonic for the drugs and measures given after an infarct.

Expansion

The four drugs, plus rehabilitation and risk factor control

Expansion

The four As, plus a B:

  • A - Aspirin, lifelong, plus a second antiplatelet for 12 months
  • A - ACE inhibitor, titrated to the maximum tolerated dose
  • A - Atorvastatin, high intensity, usually 80 mg
  • B - Beta blocker, continued at least 12 months, and indefinitely if the ejection fraction is reduced

Add an aldosterone antagonist within 3 to 14 days if there is heart failure with a reduced ejection fraction.

Non-drug measures, which matter as much

  • Cardiac rehabilitation, an exercise and education programme that reduces cardiovascular mortality
  • Smoking cessation, the single most effective intervention
  • Mediterranean style diet, weight and alcohol
  • Exercise, at least 150 minutes weekly of moderate activity
  • Blood pressure and diabetes control

Driving and work: DVLA rules require 1 week off driving after successful angioplasty and 4 weeks if untreated or unsuccessful; group 2 licences require reassessment.

Sexual activity may resume after about 4 weeks; sildenafil is contraindicated with nitrates and should be avoided for 6 months after an infarct.
