Appropriate measures for secondary prevention of MI offer significant benefits with typically low treatment costs. Despite this, according to the World Health Organization, secondary prevention measures are implemented in less than half of eligible patients, even in high-income countries.

Statins are effective for both secondary and primary prevention of fatal and nonfatal MIs. Similarly, beta-blockers have been shown to reduce the incidence of recurrent MI, sudden death, and all-cause mortality following an MI.

ACE inhibitors have been shown to reduce recurrent nonfatal MI in patients with left ventricular dysfunction who have had an MI. Additionally, ACE inhibitors are also effective in reducing ischemic events after an MI, risk for recurrent MI, unstable angina, and death from recurrent MI.
