Angiography-Derived and Sensor-Wire Methods to Assess Coronary Microvascular Dysfunction in Patients With Acute...

Area of Science:

• Cardiology
• Cardiovascular Research
• Interventional Cardiology

Background:

• Primary percutaneous coronary intervention significantly improves prognosis in ST-segment elevation myocardial infarction (STEMI).
• Coronary microvascular dysfunction (CMD) persists post-revascularization, negatively impacting long-term STEMI patient outcomes.
• Understanding and assessing coronary microcirculation is crucial for improving STEMI management.

Purpose of the Study:

• To review conventional and novel methods for assessing coronary microvascular dysfunction in STEMI patients.
• To highlight the emerging role of angiography-based indices for microcirculatory resistance assessment.
• To propose a procedural algorithm for optimal use of diagnostic tools in acute STEMI.

Main Methods:

• Review of current diagnostic techniques for coronary microvascular function, including cardiac magnetic resonance and invasive wire-based methods.
• Evaluation of angiography-based indices of microcirculatory resistance as emerging tools.
• Development of a procedural algorithm for integrating diagnostic indices in STEMI management.

Main Results:

• Existing methods for assessing microvascular function have technical and logistical limitations.
• Angiography-based indices are user-friendly and show potential for prognostic stratification in STEMI.
• Novel approaches are needed to effectively diagnose and manage CMD in STEMI.

Conclusions:

• Coronary microvascular dysfunction remains a significant challenge in STEMI management despite successful revascularization.
• Angiography-based indices represent a promising, accessible tool for evaluating microcirculatory resistance and guiding STEMI patient care.
• Standardized assessment and integration of microvascular evaluation are essential for optimizing long-term outcomes in STEMI.
