Case Report: Spontaneous coronary artery dissection presenting as MINOCA in uncontrolled Graves’ disease

1

Spontaneous coronary artery dissection (SCAD) is recognized as a cause of myocardial infarction with non-obstructive coronary arteries (MINOCA).
2

A 56-year-old female with uncontrolled Graves’ disease presented with ST-segment elevation myocardial infarction (STEMI) and was diagnosed with SCAD.
3

Emergent coronary angiography showed a long narrowing in the left anterior descending artery with preserved TIMI 3 flow, supporting a MINOCA diagnosis.
4

Intravascular ultrasound at three months confirmed a persistent intramural hematoma, solidifying the diagnosis of SCAD.
5

The case highlights the challenges of diagnosing MINOCA in hyperthyroid patients and suggests a staged approach to minimize procedural risks.
