[Silent myocardial ischemia].

Area of Science:

• Cardiology
• Clinical Medicine

Context:

• The definition of "silent myocardial ischemia" has broadened, encompassing diverse patient groups.
• This includes asymptomatic individuals alongside those with symptomatic coronary artery disease or post-myocardial infarction.

Purpose:

• To clarify the prognostic implications of "silent myocardial ischemia" in different clinical contexts.
• To differentiate the prognosis of asymptomatic individuals with abnormal stress tests from symptomatic patients.

Summary:

• "Silent myocardial ischemia" is often applied to heterogeneous patient populations.
• Prognostic data from symptomatic patients are inappropriately extrapolated to asymptomatic individuals with abnormal ECG stress tests.
• These asymptomatic individuals generally exhibit a benign clinical course.

Impact:

• Accurate definition is crucial for appropriate patient management.
• Invasive investigations and treatments are typically not justified for properly defined "silent myocardial ischemia" in asymptomatic individuals.
• This distinction can prevent unnecessary medical interventions and associated risks.
