Cardiovascular magnetic resonance (CMR) is crucial for diagnosing myocardial infarction with nonobstructive coronary arteries (MINOCA). It helps differentiate causes of heart injury, guiding effective patient management.
Area of Science:
- Cardiology
- Medical Imaging
Context:
- Myocardial infarction with nonobstructive coronary arteries (MINOCA) represents 5-10% of acute myocardial infarction cases.
- Recent guidelines (AHA 2019, ESC 2020) recommend cardiovascular magnetic resonance (CMR) for MINOCA diagnosis.
Purpose:
- To define the role and utility of CMR in evaluating patients with suspected MINOCA.
- To summarize current guidelines and present characteristic CMR findings in MINOCA.
Summary:
- CMR is recommended (Class 1B) for MINOCA cases lacking a clear cause.
- CMR excels at distinguishing between non-ischemic and ischemic myocardial injury.
Impact:
- CMR serves as a key noninvasive tool for differential diagnosis in MINOCA.
- Establishes CMR as the most important diagnostic modality for suspected MINOCA.
