RESUMO
A 68-year-old African American female with a prior medical history of hypertension and dyslipidemia presented with sudden onset pressure-like substernal chest pain. Initial ECG showed no ST or T wave abnormalities, and troponin elevation of 2.88 ng/mL. Two hours later, chest pain recurred with ECG change and increase in troponin to 11.97 ng/mL. She underwent urgent coronary angiography, which revealed left anterior descending artery dissection with thrombus. We successfully treated with balloon angioplasty followed by placement of 3 drug-eluting stents resulting in TIMI-3 flow; further testing for vasculitis was negative. Once spontaneous coronary artery dissection is diagnosed, the approach to treatment is controversial and treatment should be patient tailored.
