Current perspectives on revascularization in multivessel ST elevation myocardial infarction.

Area of Science:

• Cardiology
• Interventional Cardiology
• Acute Coronary Syndromes

Background:

• Multivessel coronary artery disease (CAD) affects up to 50% of ST-elevation myocardial infarction (STEMI) patients, correlating with poorer prognoses.
• Historically, infarct-related artery percutaneous coronary intervention (IRA-PCI) was favored over complete revascularization (CR) based on observational data.

Purpose of the Study:

• To evaluate the evolving strategies for revascularization in STEMI patients with multivessel CAD.
• To address the paradigm shift from IRA-PCI to CR, supported by recent randomized trials.

Main Methods:

• Review of clinical data and recent groundbreaking randomized trials comparing IRA-PCI with CR strategies.
• Analysis of guideline changes reflecting new evidence on revascularization approaches.

Main Results:

• Observational studies previously favored IRA-PCI, but recent randomized trials suggest CR may be equivalent or superior.
• This evidence has led to a paradigm shift in recent US and European guidelines regarding STEMI management.

Conclusions:

• Complete revascularization is increasingly recognized as a potentially superior strategy for STEMI patients with multivessel disease.
• Ongoing debates persist regarding optimal CR timing, extent, evaluation of intermediate lesions, and treatment of chronic total occlusions.
