Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS). The true
incidence of SCAD is underestimated. The pathophysiology is still not fully understood and its management can
be challenging.Patients may present with a broad spectrum of clinical scenarios, ranging from angina pectoris
to myocardial infarction, cardiogenic shock, and sudden death. Standard therapy has not been established;
current treatments range from conservative management to percutaneous revascularization or coronary
artery bypass surgery. SCAD greatly mimics ACS, and this diagnosis should be considered when
evaluating young patients who present with ACS with or without classical risk factors for coronary
artery disease.
We report a case of a 39-year old man who presented with diabetic ketoacidosis (DKA) and presentation of
ACS. He had multiple risk factors for CAD such as a smoking history of two pack-years, hypertension and poorly
controlled diabetes mellitus type I. Once the clinical findings were suggestive of acute anterior and inferior
myocardial infarction, the patient underwent emergent cardiac catheterization, which revealed distal left
anterior descending coronary artery dissection.
Conclusion: This case highlights the fact that although SCAD is a rare entity, it is increasingly being recognized
as a significant cause of ACS. Urgent angiography should be considered if SCAD is suspected, because early
diagnosis and appropriate management significantly improves the outcome.
