[Risk stratification after acute myocardial infarction]

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Patient characteristics for acute myocardial infarction (AMI) without complications have shifted.
• Advancements in non-invasive diagnostic tools now offer improved evaluation of left ventricular systolic function, residual myocardial ischemia, and myocardial viability.

Purpose of the Study:

• To outline current recommendations for assessing left ventricular systolic function and residual ischemia in post-AMI patients.
• To guide the selection of appropriate non-invasive testing modalities.
• To define the role of coronary arteriography in managing these patients.

Main Methods:

• Review of current non-invasive diagnostic techniques including exercise testing, echocardiography, nuclear cardiology, and magnetic resonance imaging.
• Guidelines for patient selection for coronary arteriography based on non-invasive findings.

Main Results:

• All patients should undergo evaluation of left ventricular systolic function and residual ischemia prior to discharge.
• The choice of non-invasive testing modality is institution-dependent, based on availability and expertise.
• Coronary arteriography is indicated for patients with significant ischemia or severe left ventricular systolic dysfunction identified non-invasively.

Conclusions:

• Comprehensive non-invasive evaluation before discharge is crucial for patients with AMI.
• Coronary arteriography is essential for revascularization planning in select patients.
• Personalized diagnostic strategies improve patient management post-myocardial infarction.
