Spontaneous coronary artery dissection (SCAD) is one of the rarest causes of acute coronary syndromes, which include myocardial infarction (MI), stable and unstable angina, cardiogenic shock, and sudden death. The course of the disease, its etiology, prevalence, prognosis, and treatment remain ill-defined. Adding to the complexity is the fact that patients may lack typical risk factors for coronary heart disease. Herein, we report a case of a 42-year-old woman with vitamin B12 deficiency, who presented with chest pain; electrocardiography (ECG) findings were consistent with the acute anterior wall MI. Cardiac catheterization was done, which showed a very large left anterior descending (LAD) artery dissection.
