Risk stratification after myocardial infarction. Clinical evaluation before discharge

Area of Science:

• Cardiology
• Clinical Risk Assessment

Background:

• Acute myocardial infarction management has been revolutionized by reperfusion strategies.
• Risk stratification is crucial for optimizing patient outcomes post-myocardial infarction.

Purpose of the Study:

• To review the evolution of risk stratification in the reperfusion era.
• To highlight advancements in risk assessment technologies and emerging frontiers.

Main Methods:

• Review of risk stratification phases (Phase I, II, III) in the reperfusion era.
• Inclusion of novel technologies such as heart rate variability and signal-averaged electrocardiogram.
• Discussion of ongoing controversies and future directions in risk stratification.

Main Results:

• Risk stratification is now time-dependent, categorized into three phases post-admission.
• New technologies enable exploration of autonomic system activation and arrhythmia substrates.
• Despite advancements, significant controversies and new research areas persist.

Conclusions:

• Risk stratification post-acute myocardial infarction has significantly evolved due to reperfusion therapies.
• Emerging technologies offer deeper insights into patient risk, but further research is needed.
• The field of risk stratification continues to advance, addressing existing controversies and exploring new frontiers.
