Coronary Microvascular Disease Early After Myocardial Infarction: Diagnostic Approach and Prognostic Value-A...

Area of Science:

• Cardiology
• Vascular Biology

Background:

• Coronary microvascular disease (CMVD) frequently complicates acute myocardial infarction (AMI), even after successful revascularization.
• Compromised microvascular function post-AMI is associated with increased cardiovascular mortality and heart failure hospitalizations.
• CMVD remains underdiagnosed, impacting patient prognosis significantly.

Purpose of the Study:

• To review diagnostic modalities for CMVD in the early post-AMI period.
• To examine the prognostic significance of CMVD development after AMI.
• To highlight challenges and opportunities in diagnosing and managing CMVD.

Main Methods:

• Review of invasive diagnostic techniques, including index of microvascular resistance (IMR) and coronary flow reserve (CFR).
• Evaluation of non-invasive methods such as echocardiography Doppler, positron emission tomography (PET), and cardiac magnetic resonance imaging (CMR).
• Analysis of the diagnostic and prognostic value of CMVD assessment early after AMI.

Main Results:

• Invasive methods (IMR, CFR) are gold standards but pose risks and complexity.
• Non-invasive techniques offer alternatives but face accessibility, cost, and implementation barriers during the peri-AMI phase.
• Early detection of CMVD is critical for patient outcomes.

Conclusions:

• Accurate diagnosis and prognostic assessment of CMVD post-AMI are essential for improving long-term results.
• Further large-scale diagnostic and prognostic studies are needed.
• A comprehensive understanding of CMVD pathophysiology is required for effective management.
