Survivors of a first acute myocardial infarction (MI) face a substantial risk of further cardiovascular events, including death, recurrent MI, heart failure, arrhythmias, angina, and stroke. Patients (and family members) often ask what their future holds; thus, information regarding prognosis after MI is necessary for patient care.

The outcomes discussed in this topic, such as mortality, are presented using pooled data. However, the prognosis may vary widely between individuals, according to the presence or absence of risk factors present before the MI. These risk factors are discussed elsewhere. (See "Risk factors for adverse outcomes after non-ST elevation acute coronary syndromes" and "Risk factors for adverse outcomes after ST-elevation myocardial infarction".)

The prognosis of young men and women after MI is discussed separately. (See "Coronary heart disease and myocardial infarction in young men and women", section on 'Prognosis after MI'.)

The likelihood of subsequent events presented here are rough estimates. For most patients with MI, clinicians should risk stratify them using validated risk prediction models. This process is described in detail separately. (See "Risk stratification after acute ST-elevation myocardial infarction" and "Risk stratification after non-ST elevation acute coronary syndrome".)

The discussion of sudden cardiac death following MI is found elsewhere. (See "Incidence of and risk stratification for sudden cardiac death after acute myocardial infarction" and 'Adverse non-fatal outcomes' below.)
