Referral to a well-structured cardiac rehabilitation program should be considered for all patients following an MI. This will encourage compliance with the program's medical regimen and improve the adoption of needed lifestyle changes. In addition, aerobic exercise training within a cardiac rehabilitation program should be offered to patients after an MI, with the need for an evaluation of both exercise capacity and exercise-associated risk.

Eating oily fish or taking omega-3 fatty acid supplements have not been shown to be effective as preventive agents following an MI (although eating oily fish has not been shown to cause harm and is part of the heart-healthy Mediterranean diet).

Smoking cessation reduces the risk for recurrent MI by 50%. All patients who smoke should be encouraged to cease smoking and be provided with smoking cessation counseling, as needed.

In addition to smoking cessation, a number of lifestyle modifications have been strongly linked to a reduction in recurrent MI and prevention of further progression of cardiovascular disease. These include the adoption of a low-fat and low-salt diet with dietary counseling (a Mediterranean-style diet is recommended), up-to-date vaccinations, and increasing physical activity and exercise.
